This study was designed to investigate the feasibility and technical strategies of laparoscopic complete mesocolic excision (CME) for right-hemi colon cancer. ⋯ CME is a novel concept for colon cancer surgery and might be a standard for the procedure. Laparoscopic CME with medial access is technically feasible and randomized trials are needed to evaluate its long-term outcomes.

Bedside diagnostic laparoscopy has an important role of diagnosing acute abdomen in critically ill patients hospitalized in the intensive care unit (ICU). Delayed diagnosis of intraabdominal pathology increases the morbidity and mortality rates for these patients, whose clinical signs often are absent due to analgesic medication and sedation. ⋯ As a minimally invasive procedure, bedside diagnostic laparoscopy can be performed in the ICU for hemodynamically unstable patients. It is safe procedure with high diagnostic accuracy for acute intraabdominal conditions that avoids negative laparotomies for unstable patients. The bedside diagnostic laparoscopy procedure is not performed widely, and prospective studies are needed to better evaluate outcome and advantages for critically ill patients.

Randomized Controlled Trial Comparative Study
Prospective randomized clinical trial comparing laparoscopic cholecystectomy and hybrid natural orifice transluminal endoscopic surgery (NOTES) (NCT00835250).
Natural orifice transluminal endoscopic surgery (NOTES) is a technique still in experimental development whose safety and effectiveness call for assessment through clinical trials. In this paper we present a three-arm, noninferiority, prospective randomized clinical trial of 1 year duration comparing the vaginal and transumbilical approaches for transluminal endoscopic surgery with the conventional laparoscopic approach for elective cholecystectomy. ⋯ NOTES approaches using the flexible endoscope are not inferior in safety or effectiveness to conventional laparoscopy. The transumbilical approach with flexible endoscope is as effective and safe as the transvaginal approach and is a promising, single-incision approach.

Randomized Controlled Trial Comparative Study
Comparison of long-term outcome and quality of life after laparoscopic repair of incisional and ventral hernias with suture fixation with and without tacks: a prospective, randomized, controlled study.
Technique of mesh fixation in laparoscopic incisional hernia repair is a matter of debate. Literature is lacking in randomized trials comparing various methods of mesh fixation. This study was designed to compare the cost-effectiveness and long-term outcomes following the two methods of mesh fixation. ⋯ The suture fixation method is a cost-effective alternative to tacker fixation in patients with small- to medium-sized defects in laparoscopic incisional and ventral hernia repair. Suture fixation is better than tacker fixation in terms of early postoperative pain and return to activity. The two procedures are equally effective regarding the recurrence rates, complications, hospital stay, chronic pain, quality of life determinants, and patient satisfaction.

Intraductal papillary mucinous neoplasm (IPMN) is characterized by intraductal proliferation of neoplastic mucinous cells with a variable extent along the main duct or its branches. The lesion may be continuous or discontinuous. Skip lesions have been described in about 6-19% of cases. Complete resection without leaving behind any skip lesions is important, to such an extent that many groups suggest even total pancreatectomy, a major and morbid surgery. ⋯ Intraoperative pancreatoscopy, especially with NBI, is a good diagnostic tool for IPMN and also helps in intraoperative decision-making of the resection margins.
