1.  Inflammatory myofibroblastic tumor mimicking hepatocellular carcinoma with dense lipiodol uptake 
Inflammatory myofibroblastic tumor (IMT) of the liver is a very rare lesion that has radiologic similarity with malignant liver tumor. Differential diagnosis of IMT from a malignant lesion of the liver is very important because surgical resection is not mandatory for IMT. Lipiodol computed tomography is a very sensitive and specific diagnostic tool for hepatocellular carcinomas (HCC). Herein, we describe a case of IMT that had dense lipiodol uptake in the tumor and mimicked HCC. To our knowledge, previously, only one case of IMT with dense lipiodol retention has been reported.

2.  Outcome of total proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis 
Purpose
We evaluated the risk factors for late complications and functional outcome after total proctocolectomy (TPC) with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC).
Methods
Pre- and postoperative clinical status and follow-up data were obtained for 55 patients who underwent TPC with IPAA between 1999 and 2010. The median follow-up duration was 4.17 years. Late complications were defined as those that appeared at least one month after surgery. For a functional assessment, telephone interviews were conducted using the Global Assessment of Functioning Scale. Twenty-eight patients completed the interview.
Results
Late complications were found in 20 cases (36.3%), comprising pouchitis (n = 8), bowel obstruction (n = 5), ileitis (n = 3), pouch associated fistula (n = 2), and intra-abdominal infection (n = 2). The preoperative serum albumin level for patients with late complications was lower than for patients without (2.4 ± 0.5 vs. 2.9 ± 0.7, P = 0.04). Functional outcomes were not significantly associated with clinical characteristics, follow-up duration, operation indication, or late complications.
Conclusion
This study demonstrated that a low preoperative albumin level could be a risk factor for late complications of TPC with IPAA. Preoperative nutritional support, especially albumin, could reduce late complications. Functional outcomes are not related to late complications.

3.  Synchronous T-cell lymphoma in patient with colon cancer: a case report 
Colorectal cancer is the third most common malignancy in Korea. In contrast, pericolic or mesenteric lymphoma is relatively rare. We experienced an extremely rare case of synchronous primary colon cancer in the ascending colon with T-cell lymphoma in the pericolic lymph node. A 79-year-old woman presented with complaints of epigastric and right lower abdominal pain combined with anorexia and nausea. Colonoscopic evaluation and biopsy were performed, and the diagnosis was cecal adenocarcinoma. She underwent right hemicolectomy with lymph node dissection. The pathology report revealed adenocarcinoma in cecum with metastasis to 1 regional lymph node out of 37 lymph nodes. In addition, there was malignant angioimmunoblastic T-cell lymphoma in 1 pericolic lymph node. There was no evidence of lymphoma in ileum, cecum and ascending colon, so the possibility of early phase of lymphoma was suggested.

4.  Large tubular colonic duplication in an adult treated with a small midline incision 
Tubular colonic duplication presenting in adults is rare and difficult to diagnose preoperatively. Only a few cases have been reported in the literature. We report a case of a 29-year-old lady presenting with a long history of chronic constipation, abdominal mass and repeated episodes of abdominal pain. The abdominal-pelvic computed tomography scan showed segmental bowel wall thickening thought to be small bowel, and dilatation with stasis of intraluminal content. The provisional diagnosis was small bowel duplication. She was scheduled for single port laparoscopic resection. However, a T-shaped tubular colonic duplication at sigmoid colon was found intraoperatively. Resection of the large T-shaped tubular colonic duplication containing multiple impacted large fecaloma and primary anastomosis was performed. There was no perioperative complication. We report, herein, the case of a T-shaped tubular colonic duplication at sigmoid colon in an adult who was successfully treated through mini-laparotomy assisted by single port laparoscopic surgery.

5.  Pancreatic serous cystadenocarcinoma with invasive growth into the colon and spleen 
Serous cystic neoplasms of the pancreas are almost always benign lesions. However, there are some case reports of malignant serous neoplasms of the pancreas. It is very difficult to distinguish malignant and benign tumors. Indeed, only clinicopathologic findings of locoregional invasion and metastasis represent a malignancy. We report a serous cystadenocarcinoma of the pancreas that was initially considered to be colon cancer. Post-operatively, the tumor was confirmed to be a malignant serous cystic tumor of the pancreas. One year later, the patient remains disease-free.

6.  Routine chest computed tomography as a preoperative work-up for primary colorectal cancer: is there any benefit in short-term outcome? 
Purpose
The aim of this study was to assess the role of pre-operative chest computed tomography (CT) compared with abdominopelvic CT (AP-CT) and chest radiography (CXR) for detecting pulmonary metastasis in patients with primary colorectal cancer (CRC).
Methods
We retrospectively analyzed the data of 619 patients with primary CRC who simultaneously received a preoperative chest CT (chest CT group), AP-CT with hilar extension, and CXR (CXR group).
Results
In the chest CT group, there were 297 (48.0%) normal, 198 (32%) benign, 96 (15.5%) indeterminate, 26 (4.2%) metastasis, and two lung cancers. Eighteen patients (2.9%) in the CXR group who had no pulmonary metastasis were diagnosed with pulmonary metastasis on a chest CT. The sensitivity and accuracy were 83.9% and 99.0% in the chest CT group, respectively, and 29.0% and 91.5% in the CXR group, respectively (P < 0.0001 and P = 0.0003).
Conclusion
Chest CT appears to improve the accuracy of pre-operative staging in patients with CRC and is useful for the early detection of pulmonary metastasis as a baseline study for abnormal lung nodules.
