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.

Risk of adhesive obstruction after colorectal surgery: the benefits of the minimally invasive approach may extend well beyond the perioperative period.
Risk of adhesive small-bowel obstruction (SBO) is high following open colorectal surgery. Laparoscopic surgery may induce fewer adhesions; however, the translation of this advantage to a reduced rate of bowel obstruction has not been well demonstrated. This study evaluates whether SBO is lower after laparoscopic compared with open colorectal surgery. ⋯ Although the rate of SBO was similar after laparoscopic and open colorectal surgery, the need for operative intervention for SBO was significantly lower after laparoscopic operations. These findings especially in the context of the longer follow-up for laparoscopic patients suggests that the lower incidence of adhesions expected after laparoscopic surgery likely translates into long-term benefits in terms of reduced SBO.

Randomized Controlled Trial Comparative Study
Laparoscopy versus open distal gastrectomy by expert surgeons for early gastric cancer in Japanese patients: short-term clinical outcomes of a randomized clinical trial.
Short-term outcomes of laparoscopy-assisted distal gastrectomy (LADG) and open DG (ODG) have been investigated in previous clinical trials, but operative techniques and concomitant treatments have evolved, and up-to-date evidence produced by expert surgeons is required to provide an accurate image of the relative efficacies of the treatments. The purpose of this study was to compare laparoscopic versus ODG with respect to specific primary and secondary short-term outcomes. ⋯ LADG performed by expert surgeons results in less postoperative pain accompanied by decreased surgical invasiveness and is associated with fewer postoperative inconveniences. No preliminary suggestions of changes in long-term curability were observed. LADG for early gastric cancer is a feasible and safe procedure with short-term clinical results superior to those of ODG.

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.
