We reviewed the long-term results and patient survival for laparoscopic-assisted resection of colorectal malignancies. The place of laparoscopic colectomy for colorectal carcinomas is controversial. The techniques and expected surgical outcomes for patients undergoing laparoscopic and laparoscopic-assisted colectomies are being defined as these procedures become more acceptable and reach parity with, or even surpass, results of traditional operations. Anecdotal reports in the literature describe port-site and incisional tumor implantation in patients undergoing laparoscopic-assisted colectomies for colorectal malignancies. This raises concerns about whether these incisional tumor sites are more common in these patients and whether their survival is compromised by the laparoscopic technique.
The authors reviewed data from 110 patients who underwent laparoscopic-assisted colectomies for colorectal cancer to determine the long-term results and survival and to compare the safety and efficacy of laparoscopic-assisted colectomy to the safety and efficacy of open colectomy. Between July 1991 and June 1999, 350 patients underwent laparoscopic-assisted colectomies. Of these, 110 patients had colorectal malignancies. Survival rates and patterns of recurrence were compared within the various TNM stages and compared with conventional data after open surgery. The American Joint Committee on Cancer staging for colorectal carcinomas and the Kaplan-Meier method were used to determine the survival curves.
Laparoscopic-assisted colon resections for colorectal malignancies were performed in 110 patients. Fifty-one percent of the patients were women, and 49% percent were men, with a mean age of 78.17 years. The mean follow-up was 43 months. Thirteen patients were converted to open operation due to various difficulties encountered during the procedure. Mean operative time was 128.16 minutes, and mean hospital stay was 6.91 days. Perioperative mortality was 2.77%. There were 4 local recurrences. The ten-year survival rates for the various stages were 78% for stage I, 33% for stage II, 30% for stage III, and 0% for stage IV. No port-site implantations occurred.
Laparoscopic-assisted colon resection of colorectal carcinomas is technically feasible and safe. It allows earlier postoperative recovery and a shorter hospital stay. The long-term survival is also satisfactory. The incidence of port-site implants is no more than that with the conventional open technique. Determination of any benefits over the conventional open technique, however, still await prospective randomized trials.

Laparoscopy-assisted surgery, fast-track perioperative treatment are both increasingly used in colorectal cancer treatment, for their short-time benefits of enhanced recovery and short hospital stays. However, the benefits of the integration of the Laparoscopy-assisted surgery, fast-track perioperative treatment, and even with the Xelox chemotherapy, are still unknown. In this study, the three treatments integration is defined as "Fast Track Multi-Discipline Treatment Model" for colorectal cancer and this model extends the benefits to the whole treatment process of colorectal cancer. The main purpose of the study is to explore the feasibility of "Fast Track Multi-Discipline Treatment" model in treatment of colorectal cancer.
The trial is a prospective randomized controlled study with 2 × 2 balanced factorial design. Patients eligible for the study will be randomized to 4 groups: (I) Laparoscopic surgery with fast track perioperative treatment and Xelox chemotherapy; (II) Open surgery with fast track perioperative treatment and Xelox chemotherapy; (III) Laparoscopic surgery with conventional perioperative treatment and mFolfox6 chemotherapy; (IV) Open surgery with conventional perioperative treatment and mFolfox6 chemotherapy. The primary endpoint of this study is the hospital stays. The secondary endpoints are the quality of life, chemotherapy related adverse events, surgical complications and hospitalization costs. Totally, 340 patients will be enrolled with 85 patients in each group.
The study initiates a new treatment model "Fast Track Multi-Discipline Treatment" for colorectal cancer, and will provide feasibility evidence on the new model "Fast Track Multi-Discipline Treatment" for patients with colorectal cancer.

In this account, addition of alvimopan to a standard perioperative recovery pathway decreased length of stay and incidence of postoperative ileus for elective laparoscopic colectomy.
Background and Objectives:
Alvimopan, a peripherally acting mu-opioid receptor antagonist, decreased time to gastrointestinal recovery and hospital length of stay in open bowel resection patients in Phase 3 trials. However, the benefit in laparoscopic colectomy patients remains unclear.
A retrospective case series review was performed to study addition of alvimopan to a well-established standard perioperative recovery pathway for elective laparoscopic colectomy. The main outcome measures were length of stay and incidence of charted postoperative ileus. Wilcoxon and chi-square tests were used to calculate P values for length of stay and postoperative ileus endpoints, respectively.
Demographic/baseline characteristics from the 101 alvimopan and 64 pre-alvimopan control patients were generally comparable. Mean length of stay in the alvimopan group was 1.55 days shorter (alvimopan, 2.81±0.95 days; control, 4.36±2.4 days; P<.0001). The proportion of patients with postoperative ileus was lower in the alvimopan group (alvimopan, 2%; control, 20%; P<.0001).
In this case series, addition of alvimopan to a standard perioperative recovery pathway decreased length of stay and incidence of postoperative ileus for elective uncomplicated laparoscopic colectomy. The improvement in the mean length of stay for patients who receive alvimopan is a step forward in achieving a fast-track surgery model for elective laparoscopic colectomies.

Laparoscopic colectomy for colon cancer has been compared with open colectomy in randomized controlled trials, but these studies may not be generalizable because of strict enrollment and exclusion criteria which may explicitly or inadvertently exclude older individuals due to associated comorbidities. Previous studies of older patients undergoing laparoscopic colectomy have generally focused on short-term outcomes. The goals of this cohort study were to identify predictors of laparoscopic colectomy in an older population in the United States and to compare short-term and long-term outcomes.
Patients aged 65 years or older with incident colorectal cancer diagnosed 1996-2002 who underwent colectomy within 6 months of cancer diagnosis were identified from the linked Surveillance, Epidemiology, and End Results-Medicare database. Laparoscopic and open colectomy patients were compared with respect to length of stay, blood transfusion requirements, intensive care unit monitoring, complications, 30-day mortality, and long-term survival. We adjusted for potential selection bias in surgical approach with propensity score matching.
Laparoscopic colectomy cases were associated with left-sided tumors; areas with higher population density, income, and education level; areas in the western United States; and National Cancer Institute-designated cancer centers. Laparoscopic colectomy cases had shorter length of stay and less intensive care unit monitoring. Although laparoscopic colectomy patients (n = 424) had fewer complications (21.5% versus 26.3%), lower 30-day mortality (3.3% versus 5.8%), and longer median survival (6.6 versus 4.8 years) compared with open colectomy patients (n = 27,012), after propensity score matching these differences disappeared.
In this older population, laparoscopic colectomy practice patterns were associated with factors which likely correlate with tertiary referral centers. Although short-term and long-term survival are comparable, laparoscopic colectomy offers shorter hospitalizations and less intensive care.
Laparoscopic colon surgery that incorporates multimodal perioperative care may allow patients to be discharged within the first 24 hours.
Background and Objectives:
A short hospital stay is one of the main advantages of laparoscopic surgery. Previous studies have shown that after a multimodal fast-track process, the hospital length of stay can be shortened to between 2 and 5 days. The objective of this review is to show that the hospital length of stay can, in some cases, be reduced to <24 hours.
This study retrospectively reviews a surgeon's experience with laparoscopic surgery over a 12-month period. Seven patients were discharged home within 24 hours after minimally invasive laparoscopic surgical treatment, following a modified fast-track protocol that was adopted for perioperative care.
Of the 7 patients, 4 received laparoscopic right hemicolectomy for malignant disease and 3 underwent sigmoid colectomies for recurrent diverticulitis. The mean hospital stay was 21 hours, 47 minutes; the mean volume of intraoperative fluid (lactated Ringer) was 1850 mL; the mean surgical blood loss was only 74.3 mL; the mean duration of surgery was 118 minutes; and the patients were ambulated and fed a liquid diet after recovery from anesthesia. The reviewed patients had functional gastrointestinal tracts and were agreeable to the timing of discharge. On the follow-up visit, they showed no adverse consequences such as bleeding, infection, or anastomotic leak.
Laparoscopic colon surgery that incorporated multimodal perioperative care allowed patients to be discharged within the first 24 hours. Careful postoperative outpatient follow-up is important in monitoring complications such as anastomotic leak, which may not present until postoperative day 5.

Evidence of benefits of laparoscopic and laparoscopic-assisted colectomies (LAC) over open procedures in gastrointestinal surgery has continued to accumulate. With its wide implementation, technical difficulties and limitations of LAC have become clear. Hand-assisted laparoscopic surgery (HALS) was introduced in an attempt to facilitate the transition from open techniques to minimally invasive procedures. Continuing debate exists about which approach is to be preferred, HALS or LAC. Several studies have compared these two techniques in colorectal surgery, but no single study provided evidence which procedure is superior. Therefore, a systematic review was carried out comparing HALS with LAC colorectal resection.
Eligible studies were identified from electronic databases (Medline, Embase Cochrane) and cross-reference search. The database search, quality assessment, and data extraction were independently performed by two reviewers. Minimal outcome criteria for inclusion were operating time, conversion rate, hospital stay, and morbidity.
Out of 468 studies a total of 13 studies were selected for comprehensive review. Two randomized controlled trials (RCT) and 11 non-RCTs, comprising 1017 patients, met the inclusion criteria. Because of possible clinical heterogeneity two groups of procedures were created: segmental colectomies and total (procto)colectomies. In the segmental colectomy group significant differences in favor of the HALS group were seen in operating time (WMD 19 min) and conversion rate (OR of 0.3 conversions). In the total (procto)colectomy group a significant difference in favor of the HALS group was seen in operating time (WMD 61 min).
This systematic review indicates that HALS provides a more efficient segmental colectomy regarding operating time and conversion rate, particularly accounting for diverticulitis. A significant operating time advantage exists for HALS total (procto)colectomy. HALS must therefore be considered a valuable addition to the laparoscopic armamentarium to avoid conversion and speed up complicated colectomies.

A fast-track perioperative procedure may achieve the same low-risk, low-morbidity results for laparoscopic colectomy patients as seen with more conventional lengths of hospital stay.
A short hospital stay is one of the main advantages of the laparoscopic surgical technique. The process of developing and studying the “fast-track” process has contributed to a better understanding of the elements of perioperative care and has resulted in the reduction in length of stay (LOS) after colectomies. As we follow and refine this well-recognized multimodal approach, further decreases in the LOS can be expected. We present 2 octogenarian patients who, after receiving laparoscopic hemicolectomies for malignant disease, were discharged home <24 hours after their operations. Postoperative follow-ups did not show any adverse reaction to the early discharge. Modifying the multimodal perioperative technique with further refinement to the surgical technique appears to allow patients to be discharged home in the first 24 hours following laparoscopic colectomy.

Laparoscopic colectomy has become the standard of care for elective resections; however, there are few data regarding laparoscopy in the emergency setting.
Using a prospectively collected database, we identified 94 patients who underwent an emergency colectomy between August 2005 and July 2008. Laparoscopic operations were performed in 42 patients and were compared to 25 who were suitable for laparoscopy but received open colectomy.
The groups had similar demographics with no difference in age, gender or surgical indications. Blood loss was lower (118ml vs. 205ml, p <0.01) and postoperative stay shorter (8 vs. 11 days, p = 0.02) in the laparoscopic patients, and perioperative mortality rates were similar between the two groups (1 vs. 3, p = 0.29).
With increasing experience, laparoscopic colectomy is a feasible option in certain emergency situations and is associated with shorter hospital stay, less morbidity, and similar mortality to that of open operation.

During the last two decades the use of laparoscopic resection and a multimodal approach known as an enhanced recovery programme, have been major changes in colorectal perioperative care. Clinical outcome improves using laparoscopic surgery to resect colorectal cancer but until recently no multicentre trial evidence had been reported regarding whether the benefits of laparoscopy still exist when open surgery is optimized within an enhanced recovery programme. The EnROL trial (Enhanced Recovery Open versus Laparoscopic) examines the hypothesis that laparoscopic surgery within an enhanced recovery programme will provide superior postoperative outcomes when compared to conventional open resection of colorectal cancer within the same programme.
EnROL is a phase III, multicentre, randomised trial of laparoscopic versus open resection of colon and rectal cancer with blinding of patients and outcome observers to the treatment allocation for the first 7 days post-operatively, or until discharge if earlier. 202 patients will be recruited at approximately 12 UK hospitals and randomised using minimization at a central computer system in a 1:1 ratio. Recruiting surgeons will previously have performed >100 laparoscopic colorectal resections and >50 open total mesorectal excisions to minimize conversion. Eligible patients are those suitable for elective resection using either technique. Excluded patients include: those with acute intestinal obstruction and patients in whom conversion from laparoscopic to open procedure is likely. The primary outcome is physical fatigue as measured by the physical fatigue domain of the multidimensional fatigue inventory 20 (MFI-20) with secondary outcomes including postoperative hospital stay; complications; reoperation and readmission; quality of life indicators; cosmetic assessments; standardized performance indicators; health economic analysis; the other four domains of the MFI-20. Pathological assessment of surgical quality will also be undertaken and compliance with the enhanced recovery programme will be recorded for all patients.
Should this trial demonstrate that laparoscopic surgery confers a significant clinical and/or health economic benefit this will further support the transition to this type of surgery, with implications for the training of surgeons and resource allocation.

Laparoscopy continues to be increasingly adopted for elective colorectal resections. However, its role in an emergency setting remains controversial. The aim of this study was to compare the outcomes between laparoscopic and open colectomies performed for emergency colorectal conditions.
A retrospective review of all patients who underwent emergency laparoscopic colectomies for various surgical conditions was performed. These patients were matched for age, gender, surgical diagnosis and type of surgery with patients who underwent emergency open colectomies.
Twenty-three emergency laparoscopic colectomies were performed from April 2006 to October 2011 for patients with lower gastrointestinal tract bleeding (6), colonic obstruction (4) and colonic perforation (13). The hand-assisted laparoscopic technique was utilized in 15 cases (65.2%). There were 4 (17.4%) conversions to the open technique. The operative time was longer in the laparoscopic group (175 minutes vs. 145 minutes, P = 0.04), and the duration of hospitalization was shorter in the laparoscopic group (6 days vs. 7 days, P = 0.15). The overall postoperative morbidity rates were similar between the two groups (P = 0.93), with only 3 patients in each group requiring postoperative surgical intensive-care-unit stays or reoperations. There were no mortalities. The cost analysis did not demonstrate any significant differences in the procedural (P = 0.57) and the nonprocedural costs (P = 0.48) between the two groups.
Emergency laparoscopic colectomy in a carefully-selected patient group is safe. Although the operative times were longer, the postoperative outcomes were comparable to those of the open technique. The laparoscopic group did not incur a higher cost.

Purpose. Short hospital stay and equal or reduced complication rates have been demonstrated after fast track open colonic surgery. However, fast track principles of perioperative care can be difficult to implement and often require increased nursing staff because of more concentrated nursing tasks during the shorter hospital stay. Specific data on nursing requirements after laparoscopic surgery are lacking. The purpose of the study was to evaluate the effect of operative technique (open versus laparoscopic operation), but without changing nurse staffing or principles for peri- or postoperative care, that is, without implementing fast track principles, on length of stay after colorectal resection for cancer. Methods. Records of all patients operated for colorectal cancer from November 2004 to December 2008 in our department were reviewed. No specific patients were selected for laparoscopic repair, which was solely dependent on the presence of two specific surgeons at the same time. Thus, the patients were not selected for laparoscopic repair based on patient-related factors, but only on the simultaneous presence of two specific surgeons on the day of the operation. Results. Of a total of 540 included patients, 213 (39%) were operated by a laparoscopic approach. The median hospital stay for patients with a primary anastomosis was significantly shorter after laparoscopic than after conventional open surgery (5 versus 8 days, P < 0.001) while there was no difference in patients receiving a stoma (10 versus 10 days, ns), with no changes in the perioperative care regimens. Furthermore there were significant lower blood loss (50 versus 200 mL, P < 0.001) and lower complication rate (21% versus 32%, P = 0.006) in the laparoscopic group. Conclusion. Implementing laparoscopic colorectal surgery in our department resulted in shorter hospital stay without using fast track principles for peri- and postoperative care in patients not receiving a stoma during the operation. Consequently, we aimed to reduce hospitalisation without increasing cost in nursing staff per hospital bed. Length of stay was not reduced in patients receiving a stoma pointing at this group for specific intervention in the future. Furthermore, the complication rate was reduced in the laparoscopic group.
AIM: To analyze our results after the introduction of a fast-track (FT) program after laparoscopic liver surgery in our Hepatobiliarypancreatic Unit.
METHODS: All patients (43) undergoing laparoscopic liver surgery between March 2004 and March 2010 were included and divided into two consecutive groups: Control group (CG) from March 2004 until December 2006 with traditional perioperative cares (17 patients) and fast-track group (FTG) from January 2007 until March 2010 with FT program cares (26 patients). Primary endpoint was the influence of the program on the postoperative stay, the amount of re-admissions, morbidity and mortality. Secondarily we considered duration of surgery, use of drains, conversion to open surgery, intensive cares needs and transfusion.
RESULTS: Both groups were homogeneous in age and sex. No differences in technique, time of surgery or conversion to open surgery were found, but more malignant diseases were operated in the FTG, and then transfusions were higher in FTG. Readmissions and morbidity were similar in both groups, without mortality. Postoperative stay was similar, with a median of 3 for CG vs 2.5 for FTG. However, the 80.8% of patients from FTG left the hospital within the first 3 d after surgery (58.8% for CG).
CONCLUSION: The introduction of a FT program after laparoscopic liver surgery improves the recovery of patients without increasing complications or re-admissions, which leads to a reduction of the stay and costs.

Over the last three decades, emergency surgery for perforated sigmoid diverticulitis has evolved dramatically but remains controversial. Diverticulitis is categorized as uncomplicated (amenable to outpatient treatment) versus complicated (requiring hospitalization). Patients with complicated diverticulitis undergo computerized tomography (CT) scanning and the CT findings are used categorize the severity of disease. Treatment of stage I (phlegmon with or without small abscess) and stage II (phlegmon with large abscess) diverticulitis (which includes bowel rest, intravenous antibiotics and percutaneous drainage (PCD) of the larger abscesses) has not changed much over last two decades. On the other hand, treatment of stage III (purulent peritonitis) and stage IV (feculent peritonitis) diverticulitis has evolved dramatically and remains morbid. In the 1980s a two stage procedure (1st - segmental sigmoid resection with end colostomy and 2nd - colostomy closure after three to six months) was standard of care for most general surgeons. However, it was recognized that half of these patients never had their colostomy reversed and that colostomy closure was a morbid procedure. As a result starting in the 1990s colorectal surgical specialists increasing performed a one stage primary resection anastomosis (PRA) and demonstrated similar outcomes to the two stage procedure. In the mid 2000s, the colorectal surgeons promoted this as standard of care. But unfortunately despite advances in perioperative care and their excellent surgical skills, PRA for stage III/IV diverticulitis continued to have a high mortality (10-15%). The survivors require prolonged hospital stays and often do not fully recover. Recent case series indicate that a substantial portion of the patients who previously were subjected to emergency sigmoid colectomy can be successfully treated with less invasive nonoperative management with salvage PCD and/or laparoscopic lavage and drainage. These patients experience a surprisingly lower mortality and more rapid recovery. They are also spared the need for a colostomy and do not appear to benefit from a delayed elective sigmoid colectomy. While we await the final results ongoing prospective randomized clinical trials testing these less invasive alternatives, we have proposed (based primarily on case series and our expert opinions) what we believe safe and rationale management strategy.

In the late '80s the successes of the laparoscopic surgery for gallbladder disease laid the foundations on the modern use of this surgical technique in a variety of diseases. In the last 20 years, laparoscopic colorectal surgery had become a popular treatment option for colorectal cancer patients.
Many studies emphasized on the benefits stating the significant advantages of the laparoscopic approach compared with the open surgery of reduced blood loss, early return of intestinal motility, lower overall morbidity, and shorter duration of hospital stay, leading to a general agreement on laparoscopic surgery as an alternative to conventional open surgery for colon cancer. The reduced hospital stay may also decrease the cost of the laparoscopic surgery for colorectal cancer, despite th higher operative spending compared with open surgery. The average reduction in total direct costs is difficult to define due to the increasing cost over time, making challenging the comparisons between studies conducted during a time range of more than 10 years. However, despite the theoretical advantages of laparoscopic surgery, it is still not considered the standard treatment for colorectal cancer patients due to technical limitations or the characteristics of the patients that may affect short and long term outcomes.
The laparoscopic approach to colectomy is slowly gaining acceptance for the management of colorectal pathology. Laparoscopic surgery for colon cancer demonstrates better short-term outcome, oncologic safety, and equivalent long-term outcome of open surgery. For rectal cancer, laparoscopic technique can be more complex depending on the tumor location. The advantages of minimally invasive surgery may translate better care quality for oncological patients and lead to increased cost saving through the introduction of active enhanced recovery programs which are likely cost-effective from the perspective of the hospital health-care providers.
Laparoscopic colon and rectal surgery requires advanced laparoscopic skills. The aim of this study was to describe a novel technique for laparoscopic-assisted colectomy using only 2 ports and to review our initial experience with this technique for patients with benign colonic pathologies.
A retrospective chart review of all patients who had laparoscopic-assisted colon surgery using this technique was performed. The technique is described.
For right colectomy, a 10-mm trocar for the camera was placed just below the umbilicus and a 5-mm working port just above the umbilicus. The colon was mobilized using one instrument and gravity assistance. The incisions were then connected, and the mobilized colon was pulled through this incision. For left-sided colectomy, the 5-mm working port was placed at the left suprapubic hairline, which was then extended for removal of the specimen. Sixty patients with benign colonic pathologies had laparoscopic-assisted colon surgery using only 2 ports. Conversion to open surgery was required in 4 cases. The average length of the skin incision was 3.82 cm, and the mean length of hospital stay was 4.18 days. Postoperative complications occurred in 11 patients (18%) and included anastomotic leak in 1 patient and wound infection in 2.
Laparoscopic-assisted segmental colectomy using 2 ports is easy and feasible, with minimal skin incisions and fast recovery. Our initial experience suggests that it may be easier for the experienced colorectal surgeon to acquire the skills needed to perform this technique.

AIM: To systematically review the evidence for the effectiveness of fast-track program vs traditional care in laparoscopic or open surgery for gastric cancer.
METHODS: PubMed, Embase and the Cochrane library databases were electronically searched for published studies between January 1995 and April 2013, and only randomized trials were included. The references of relevant studies were manually searched for further studies that may have been missed. Search terms included “gastric cancer”, “fast track” and “enhanced recovery”. Five outcome variables were considered most suitable for analysis: postoperative hospital stay, medical cost, duration to first flatus, C-reactive protein (CRP) level and complications. Postoperative hospital stay was calculated from the date of operation to the date of discharge. Fixed effects model was used for meta-analysis.
RESULTS: Compared with traditional care, fast-track program could significantly decrease the postoperative hospital stay [weighted mean difference (WMD) = -1.19, 95%CI: -1.79--0.60, P = 0.0001, fixed model], duration to first flatus (WMD = -6.82, 95%CI: -11.51--2.13, P = 0.004), medical costs (WMD = -2590, 95%CI: -4054--1126, P = 0.001), and the level of CRP (WMD = -17.78, 95%CI: -32.22--3.35, P = 0.0001) in laparoscopic surgery for gastric cancer. In open surgery for gastric cancer, fast-track program could also significantly decrease the postoperative hospital stay (WMD = -1.99, 95%CI: -2.09--1.89, P = 0.0001), duration to first flatus (WMD = -12.0, 95%CI: -18.89--5.11, P = 0.001), medical cost (WMD = -3674, 95%CI: -5025--2323, P = 0.0001), and the level of CRP (WMD = -27.34, 95%CI: -35.42--19.26, P = 0.0001). Furthermore, fast-track program did not significantly increase the incidence of complication (RR = 1.39, 95%CI: 0.77-2.51, P = 0.27, for laparoscopic surgery; and RR = 1.52, 95%CI: 0.90-2.56, P = 0.12, for open surgery).
CONCLUSION: Our overall results suggested that compared with traditional care, fast-track program could result in shorter postoperative hospital stay, less medical costs, and lower level of CRP, with no more complications occurring in both laparoscopic and open surgery for gastric cancer.

Background and Objectives:
Laparoscopic colectomies, with and without robotic assistance, are performed to treat both benign and malignant colonic disease. This study compared clinical and economic outcomes for laparoscopic colectomy procedures with and without robotic assistance.
Patients aged ≥18 years having primary inpatient laparoscopic colectomy procedures (cecectomy, right hemicolectomy, left hemicolectomy, and sigmoidectomy) identified by International Classification of Diseases, Ninth Edition procedure codes performed between 2009 and the second quarter of 2011 from the Premier Hospital Database were studied. Patients were matched to a control cohort using propensity scores for disease, comorbidities, and hospital characteristics and were matched 1:1 for specific colectomy procedure. The outcomes of interest were hospital cost of laparoscopic robotic-assisted colectomy compared with traditional laparoscopic colectomy, surgery time, adverse events, and length of stay.
Of 25 758 laparoscopic colectomies identified, 98% were performed without robotic assistance and 2% were performed with robotic assistance. After matching, 1066 patients remained, 533 in each group. Lengths of stay were not significantly different between the matched cohorts, nor were rates of major, minor, and/or surgical complications. Inpatient procedures with robotic assistance were significantly more costly than those without robotic assistance ($17 445 vs $15 448, P = .001). Operative times were significantly longer for robotic-assisted procedures (4.37 hours vs 3.34 hours, P < .001).
Segmental colectomies can be performed safely by either laparoscopic or robotic-assisted methods. Increased per-case hospital costs for robotic-assisted procedures and prolonged operative times suggest that further investigation is warranted when considering robotic technology for routine laparoscopic colectomies.

Both laparoscopic and fast-track surgery (FTS) have shown some advantages in colorectal surgery. However, the effectiveness of using both methods together is unclear. We performed this meta-analysis to compare the effects of FTS with those of traditional perioperative care in laparoscopic colorectal cancer surgery.
We searched the PubMed, EMBASE, Cochrane Library, and Ovid databases for eligible studies until April 2014. The main end points were the duration of the postoperative hospital stay, time to first flatus after surgery, time of first bowel movement, total postoperative complication rate, readmission rate, and mortality.
Five randomized controlled trials and 5 clinical controlled trials with 1,317 patients were eligible for analysis. The duration of the postoperative hospital stay (weighted mean difference [WMD], –1.64 days; 95% confidence interval [CI], –2.25 to –1.03; p < 0.001), time to first flatus (WMD, –0.40 day; 95% CI, –0.77 to –0.04; p = 0.03), time of first bowel movement (WMD, –0.98 day; 95% CI, –1.45 to –0.52; p < 0.001), and total postoperative complication rate (risk ratio [RR], 0.67; 95% CI, 0.56–0.80; p < 0.001) were significantly reduced in the FTS group. No significant differences were noted in the readmission rate (RR, 0.64; 95% CI, 0.41–1.01; p = 0.06) or mortality (RR, 1.55; 95% CI, 0.42–5.71; p = 0.51).
Among patients undergoing laparoscopic colorectal cancer surgery, FTS is associated with a significantly shorter postoperative hospital stay, more rapid postoperative recovery, and, notably, greater safety than is expected from traditional care.

Postoperative ileus (POI) is a transient loss of coordinated peristalsis precipitated by surgery and exacerbated by opioid pain medication. Ileus causes a variety of symptoms including bloating, pain, nausea, and vomiting, but particularly delays tolerance of oral diet and liquids. Thus POI is a primary determinant of hospital stay after surgery. ‘Fast-track’ recovery protocols, opioid sparing analgesia, and laparoscopic surgery reduce but do not eliminate postoperative ileus. Alvimopan is a mu opioid receptor antagonist that blocks the effects of opioids on the intestine, while not interfering with their centrally mediated analgesic effect. Several large randomized clinical trials have demonstrated that alvimopan accelerates the return of gastrointestinal function after surgery and subsequent hospital discharge by approximately 20 hours after elective open segmental colectomy. However, it has not been tested in patients undergoing laparoscopic surgery and is less effective in patients receiving nonsteroidal anti-inflammatory agents in a narcotic sparing postoperative pain control regimen. Safety concerns seen with chronic low dose administration of alvimopan for opioid bowel dysfunction have not been noted with its acute use for POI.

The feasibility of laparoscopic sigmoid colectomy for diverticular disease has now been well established. We report herein our experience with laparoscopic sigmoid colectomy in 100 patients who underwent laparoscopic colectomy for chronic diverticular disease.
A retrospective review was performed of a 7-year period from January 1995 to June 2002. Chronic diverticular disease was treated with laparoscopic sigmoid colectomy in 100 patients. The setting was a community hospital. All cases were performed by 1 of 2 colorectal surgeons. All laparoscopic sigmoid colectomy patients received lighted ureteral stents placed preoperatively that were removed at the end of surgery.
Mean age was 61.6 years. The male to female ratio was 38:62. The mean estimated blood loss was 138 mL, liquid diet was tolerated for 2.4 days, and hospital length of stay was 4.6 days. The mean operative time for laparoscopic sigmoid colectomy was 196 minutes. Relative complications for laparoscopic sigmoid colectomy are as follows: anastomotic leak in 2 (3.0%) patients, hematuria in 95 (95%) with an average duration for 3.1 days, urinary tract infection in 6 (6%), and ureteral injury in 1 (1%). The mean operating room charges in the laparoscopic sigmoid colectomy patients was $9,643.
We recommend laparoscopic sigmoid colectomy as the modality of treatment for chronic diverticular disease. Laparoscopic sigmoid colectomy appears to be a reliable, safe, and efficacious treatment modality for chronic diverticular disease. The operative time for laparoscopic sigmoid colectomy is decreasing as surgeons gain more experience.

Several multi-institutional prospective randomized trials have demonstrated short-term benefits using laparoscopy. Now the laparoscopic approach is accepted as an alternative to open surgery for colon cancer. However, in prior trials, the transverse colon was excluded. Therefore, it has not been determined whether laparoscopy can be used in the setting of transverse colon cancer. This study evaluated the peri-operative clinical outcomes and oncological quality by pathologic outcomes of laparoscopic surgery for transverse colon cancer.
Materials and methods
Analysis of the medical records of patients who underwent laparoscopic colorectal resection from August 2004 to November 2007 was made. Computed tomography, barium enema, and colonoscopy were performed to localize the tumor preoperatively. Extended right hemicolectomy, transverse colectomy, and extended left hemicolectomy were performed for transverse colon cancer. Surgical outcomes and pathologic outcomes were compared between transverse colon cancer (TCC) and other site colon cancer (OSCC).
Of the 312 colorectal cancer patients, 94 patients underwent laparoscopic surgery for OSCC, and 34 patients underwent laparoscopic surgery for TCC. Patients with TCC were similar to patients with OSCC in age, gender, body mass index, operating time, blood loss, time to pass flatus, start of diet, hospital stay, tumor size, distal resection margin, proximal resection margin, number of lymph nodes, and radial margin. One case in TCC and three cases in OSCC were converted to open surgery.
Laparoscopic surgery for transverse colon cancer and OSCC had similar peri-operative clinical and acceptable pathological outcomes.

Compared to the open approach, randomized trials have shown that laparoscopic colectomy is associated with a shorter hospitalization without increases in morbidity or mortality rates. With broader adoption of laparoscopic colectomy for cancer in the United States, it is unclear if laparoscopic colectomy continues to be associated with shorter hospitalization and comparable morbidity.
To determine if hospitals where a greater proportion of colon resections for cancer are approached laparoscopically (laparoscopy rate) achieve improved short-term outcomes compared to hospitals with lower laparoscopy rates.
From the 2008–2009 Nationwide Inpatient Sample, we identified hospitals where ≤12 colon resections for cancer where reported with ≥1 approached laparoscopically. We assessed the correlation between a hospital’s laparoscopy rate and risk-standardized outcomes (intra- and post-operative morbidity, in-hospital mortality rates, and average length of stay).
Overall, 6,806 colon resections were performed at 276 hospitals. Variation was noted in hospital laparoscopy rates (median=52.0%, range=3.8–100%) and risk-standardized intra- (2.7%, 1.8–8.6%) and post-operative morbidity (27.8%, 16.4–53.4%), in-hospital mortality (0.7%, 0.3–42.0%), and average length of stay (7.0 days, 4.9–10.3 days). While no association was noted with in-hospital mortality, higher laparoscopy rates were correlated with lower post-operative morbidity (correlation coefficient [r]=−0.12, p=0.04) and shorter hospital stays (r=−0.23, p<0.001), but higher intra-operative morbidity (r=0.19, p<0.001) rates. This was not observed among hospitals with high procedure volumes.
Higher laparoscopy rates were associated with only slightly lower post-operative morbidity rates and modestly shorter hospitalizations.
Laparoscopic colectomy; surgical outcomes
This report suggests that the learning curve for a surgeon with advanced laparoscopic skills may be short, requiring approximately 10 cases to decrease operative times to baseline.
Background and Objectives:
Single-port laparoscopic colectomy is described as a new technique in colorectal surgery. The initial case reports show the safety and feasibility, but the learning curve for this technique is unknown.
Between July 2009 and September 2010, 20 consecutive patients with an indication for right hemicolectomy underwent a single-port laparoscopic approach without bias in selection. The only exclusion criterion was a prior midline laparotomy. The patients were followed up for 30 days. Chart review was completed for up to 35 months to assess long-term morbidity and mortality rates.
The median age was 65 years (range, 59–88 years). Ninety percent of patients were men. The median body mass index was 28 kg/m2 (range, 20–35 kg/m2). Seventy-five percent of patients had significant comorbidities with an American Society of Anesthesiologists class of 3 or 4. The estimated blood loss was 25 mL (range, 25–250 mL). The median number of pathologic lymph nodes for patients diagnosed with adenocarcinoma was 16 (range, 8–23). There was one conversion to hand-assisted laparoscopic (case 6) and one to open colectomy (case 9) because of the inability to achieve safe vessel ligation. The median hospital stay was 4.5 days (range, 3–7 days). The length of stay for the first 10 patients was 5.1 days, and it was 3.9 days for the last 10 patients (P = .045). There were no significant postoperative complications within 30 days. The mean operative time for the first 10 cases was 198 minutes (range, 148–272 minutes), and it was 123 minutes (range, 98–150 minutes) for the subsequent 10 cases (P = .0001). All intraoperative complications (minor bleeding) occurred within the first 10 patients, with no significant bleeding recorded for the last 10 cases.
Single-port laparoscopic right hemicolectomy can be safely performed in patients who are candidates for conventional or hand-assisted right hemicolectomy with very low intraoperative and postoperative complication rates. The 30-day morbidity rate remained low with this technique. The higher technical difficulty compared with conventional laparoscopy is reflected in the longer initial operative times. The learning curve for a surgeon with advanced laparoscopic skills and adequate procedure numbers seems to be short, requiring approximately 10 cases to decrease operative times to baseline. The role and feasibility of broad adaptation for single-incision laparoscopy in colorectal surgery need to be further evaluated in larger case series and trials.

The benefits of the laparoscopic approach to colon and rectal surgery do not seem as great as for other laparoscopic procedures. To study this further we decided to review the current literature and the 10-year experience of a surgical group from university teaching hospitals in Montréal, Québec and Toronto in performing laparoscopic colon and rectal surgery.
The prospectively designed case series comprised all patients having laparoscopic colon and rectal surgery. The procedures were carried out by a group of 4 surgeons between April 1991 and November 2001. We noted intraoperative complications, any conversions to open surgery, operating time, postoperative complications and postoperative length of hospital stay.
The group attempted 750 laparoscopic colon and rectal procedures of which 669 were completed laparoscopically. Malignant disease was the indication for surgery in 49.6% of cases. Right hemicolectomy and sigmoid colectomy accounted for 54.5% of procedures performed. Intraoperative complications occurred in 8.3%, with 29.0% of these resulting in conversion to open surgery. The overall rate of conversion to open surgery was 10.8%, most commonly for oncologic concerns. Median operating time was 175 minutes for all procedures. Postoperative complications occurred in 27.5% of procedures completed laparoscopically but were mostly minor wound complications. Pulmonary complications occurred in only 1.0%. The anastomotic leak rate was 2.5%. The early reoperation rate was 2.4%. Postoperative mortality was 2.2%. No port site metastases have yet been detected. The median postoperative length of stay was 5 days.
The clinical outcomes of laparoscopic colon and rectal surgery in this 10-year experience are consistent with numerous cohort studies and randomized clinical trials. Laparoscopic colon and rectal surgery in the hands of well-trained surgeons can be performed safely with short hospital stay, low analgesic requirements and acceptable complication rates compared with historical controls and other reports in the literature. Evidence from published randomized clinical trials is emerging that under these conditions laparoscopic resection represents the better treatment option for most benign conditions, but concerns regarding its appropriateness for malignant disease are still to be resolved.
Results of this study suggest that laparoscopic surgery for diverticular disease is a safe, feasible, and effective management strategy.
Surgical treatment of complicated colonic diverticular disease is still debatable. The aim of this prospective study was to evaluate the outcome of laparoscopic sigmoid colectomy in patients with diverticulitis. Patients offered laparoscopic surgery presented with acute complicated diverticulitis (Hinchey type I, II, III), chronically recurrent diverticulitis, bleeding, or sigmoid stenosis caused by chronic diverticulitis.
All patients who underwent laparoscopic colectomy within a 12-year period were prospectively entered into a database registry. One-stage laparoscopic resection and primary anastomosis constituted the planned procedure. A 4-trocar approach with suprapubic minilaparotomy was performed. Main data recorded were age, sex, postoperative pain, return of bowel function, operation time, duration of hospital stay, and early and late complications.
During the study period, 260 sigmoid colectomies were performed for diverticulitis. The cohort included 104 male and 156 female patients; M to F ratio was 4:6. Postoperative pain was controlled by NSAIDs or weak opioid analgesia. Fifteen patients (5.7%) required conversion from laparoscopic to open colectomy. The most common reasons for conversion were directly related to the inflammatory process, abscess, and peritonitis. Mean operative time was 130±54. Average postoperative hospital stay was 10±3 days. A longer hospital stay was recorded for Hinchey type IIb patients. Complications were recorded in 30 patients (11.5%). The most common complications that required reoperation were hemorrhage in 2 patients (0.76) and anastomotic leak in 5 patients (only 3 of them required reoperation). The mortality among them was 2 patients (0.76%).
Laparoscopic surgery for diverticular disease is safe, feasible, and effective. Therefore, laparoscopic colectomy has replaced open resection as standard surgery for recurrent and complicated diverticulitis at our institution.
