Comparative Study Observational Study
Short- and long-term outcomes of intracorporeal versus extracorporeal ileocolic anastomosis in laparoscopic right hemicolectomy for colon cancer.
We assessed the short- and long-term outcomes of intracorporeal ileocolic anastomosis (IA) in laparoscopic right hemicolectomy for colon cancer compared with extracorporeal anastomosis (EA). ⋯ Compared with the extracorporeal anastomosis technique, intracorporeal ileocolic anastomosis produces comparable short- and long-term outcomes in laparoscopic right hemicolectomy for colon cancer.

Laparoscopy-assisted gastrectomy (LG) is an established treatment for early gastric cancer. However, carbon dioxide pneumoperitoneum during laparoscopic surgery can adversely affect the pulmonary function of patients with chronic obstructive pulmonary disease (COPD). This retrospective cohort study was performed to assess the feasibility of LG for patients with COPD. ⋯ The LG procedure is tolerated in patients with gastric cancer who have mild or moderate COPD, similar to OG.

Comparative Study
Face and construct validation of a virtual peg transfer simulator.
The Fundamentals of Laparoscopic Surgery (FLS) trainer box is now established as a standard for evaluating minimally invasive surgical skills. A particularly simple task in this trainer box is the peg transfer task which is aimed at testing the surgeon's bimanual dexterity, hand-eye coordination, speed, and precision. The Virtual Basic Laparoscopic Skill Trainer (VBLaST) is a virtual version of the FLS tasks which allows automatic scoring and real-time, subjective quantification of performance without the need of a human proctor. In this article we report validation studies of the VBLaST peg transfer (VBLaST-PT) simulator. ⋯ VBLaST-PT showed both face and construct validity and has promise as a substitute for the FLS for training peg transfer skills.

Although the mortality from bariatric surgery is low, perioperative determinants of morbidity and mortality in the bariatric surgery population to date have not been fully defined. This study aimed to evaluate the factors capable of predicting perioperative mortality based on preoperative characteristics with a national patient sample. ⋯ This model provides a straightforward, precise, and easily applicable tool for identifying bariatric patients at low, intermediate, and high risk for in-hospital mortality. Notably, baseline functional status before surgery is the single most powerful predictor of perioperative survival and should be incorporated into risk stratification models.

Randomized Controlled Trial Comparative Study
Laparo-endoscopic single-site (LESS) cholecystectomy with epidural vs. general anesthesia.
Laparo-endoscopic single-site (LESS) surgery involves a single umbilical incision, lending itself to epidural anesthesia. This prospective, randomized study was undertaken to evaluate epidural anesthesia for patients undergoing LESS cholecystectomy, to assess the feasibility, and to analyze all intraoperative and postoperative complications. The secondary objectives were to determine differences in postoperative pain and time until PACU discharge-to-home readiness between patients. ⋯ LESS cholecystectomy with epidural anesthesia was completed with no operative or anesthetic conversions, and less postoperative pain at discharge. Epidural anesthesia appears to be a preferable alternative to general anesthesia for patients undergoing LESS cholecystectomy.
