1.  Systematic Review of Surgical Approaches for Adrenal Tumors: Lateral Transperitoneal versus Posterior Retroperitoneal and Laparoscopic versus Robotic Adrenalectomy 
Background. Laparoscopic lateral transperitoneal adrenalectomy (LTA) has been the standard method for resecting benign adrenal gland tumors. Recently, however, laparoscopic posterior retroperitoneal adrenalectomy (PRA) has been more popular as an alternative method. This systematic review evaluates current evidence on adrenalectomy techniques, comparing laparoscopic LTA with PRA and laparoscopic adrenalectomy with robotic adrenalectomy. Methods. PubMed, Embase, and ISI Web of Knowledge databases were searched systematically for studies comparing surgical outcomes of laparoscopic LTA versus PRA and laparoscopic versus robotic adrenalectomy. The studies were evaluated according to the PRISMA statement. Results. Eight studies comparing laparoscopic PRA and LTA showed that laparoscopic PRA was superior or at least comparable to laparoscopic LTA in operation time, blood loss, pain score, hospital stay, and return to normal activity. Conversion rates and complication rates were similar. Six studies comparing robotic and laparoscopic adrenalectomy found that outcomes and complications were similar. Conclusion. Laparoscopic PRA was more effective than LTA, especially in reducing operation time and hospital stay, but there was no evidence showing that robotic adrenalectomy was superior to laparoscopic adrenalectomy. Cost reductions and further technical advances are needed for wider application of robotic adrenalectomy.

2.  Antiadhesive effect and safety of sodium hyaluronate-carboxymethyl cellulose membrane in thyroid surgery 
Purpose
A number of researchers have suggested the use of sodium hyaluronate carboxymethyl cellulose (HA-CMC) membrane for preventing postoperative adhesion. This study evaluated the antiadhesive effect and safety of HA-CMC membrane in thyroidectomy for papillary thyroid cancer.
Methods
One hundred sixty-two patients who underwent thyroidectomy were prospectively randomized. In the study group of 80 patients, the 7.5 cm × 13 cm HA-CMC membrane was applied to the operative field after thyroidectomy. The subjects were asked about complications including adhesive symptoms using an 8-item questionnaire at 2 weeks, 3 months, and 6 months after surgery. In addition, items on the appearance of neck wrinkles and scars were evaluated by a physician who had no information about the patient's allocation.
Results
There were no significant differences in complications such as swallowing difficulty, and wrinkles between study and control groups. Both groups presented significantly decreased scores over time in swallowing difficulty, and wrinkles. There were no complications regarding the HA-CMC membrane.
Conclusion
The antiadhesive effect of HA-CMC membrane in thyroid surgery is still uncertain, although it is biologically safe. Further investigation is needed to confirm the antiadhesive effect of HA-CMC membrane in thyroid surgery.

3.  Analysis of patients with anaplastic thyroid cancer expected to have curative surgery 
Purpose
Anaplastic thyroid cancer (ATC) is rare and has a poor prognosis. The aim of this study was to analyze the clinicopathologic characteristics of patients diagnosed with ATC expected to undergo curative thyroidectomy, with the goal of finding differences between patients surviving ≥6 months and <6 months.
Methods
From 1981 to 2010, 24 patients underwent thyroidectomy due to ATC. Among those patients, 12 suspected of distant metastasis preoperatively were excluded. The remaining 12 patients were analyzed by retrospective review of electronic medical records.
Results
Median age was 55 years, and the male to female ratio was 1:5. All patients presented with neck mass at initial diagnosis. Five patients lived <6 months and seven patients lived ≥6 months after operation. In patients surviving ≥6 months, all lesions were <5 cm and all patients underwent total thyroidectomy. In patients surviving <6 months, two of the four lesions were >5 cm, and two of the five patients underwent less than total thyroidectomy (P = 0.287 and 0.152, respectively). All patients with lesion size <5 cm underwent total thyroidectomy and showed a shorter median operation time (P = 0.182 and 0.033, respectively).
Conclusion
ATC showed female predominance. Patients initially presented with neck mass, and median age was 55 years. In patients with ATC who are expected to undergo curative thyroidectomy, surgery should actively be considered as primary therapy for patient survival when the size is <5 cm.
