Randomized Controlled Trial Multicenter Study Comparative Study
Randomized clinical study for assessment of incision characteristics and pain associated with LESS versus laparoscopic cholecystectomy.
Laparoendoscopic single-site surgery (LESS) has emerged as a technique that uses a natural scar, the umbilicus, within which a multiple-entry portal is placed into a 3.0-4.0-cm single incision to perform operations. The objective of this study was to compare incision size, wound complications, and postoperative pain of LESS compared with those of laparoscopic cholecystectomy (LC). ⋯ The LESS single-port (SP) operations demand a bigger incision than LC surgery. However, there were no differences in healing, wound infections, and hernia development. We found a tendency of less postoperative pain associated with LESS/SP than with LC.

Multicenter Study
The laparoscopic modified Sugarbaker technique is safe and has a low recurrence rate: a multicenter cohort study.
Parastomal hernia is a frequent complication of intestinal stomata. Mesh repair gives the best results, with the mesh inserted via laparotomy or laparoscopically. It was the aim of this retrospective multicenter study to determine the early and late results of the laparoscopically performed, modified Sugarbaker technique with ePTFE mesh. ⋯ The laparoscopic Sugarbaker technique is a safe procedure for repairing parastomal hernias. In our study, the overall morbidity was 19 % and the recurrence rate was 6.6 % after a mean follow-up of 26 months. Moreover, the laparoscopic approach revealed concomitant hernias in 41 % of the patients, which could be repaired successfully at the same time.

Laparoscopic intersphincteric resection (Lap ISR) is not yet an established technique and its safety and feasibility are unclear. Our aim was to clarify the safety and feasibility of Lap ISR for clinical stage 0/I rectal cancer (Lap RC) in a prospective multicenter study of laparoscopic surgery in Japan. ⋯ Lap ISR was feasible and safe for clinical stage 0/I rectal cancer with favorable short-term outcome.

Randomized Controlled Trial Multicenter Study
Drain after elective laparoscopic cholecystectomy. A randomized multicentre controlled trial.
Routine drainage after laparoscopic cholecystectomy is still debatable. The present study was designed to assess the role of drains in laparoscopic cholecystectomy performed for nonacutely inflamed gallbladder. ⋯ The present study was unable to prove that the drain was useful in elective, uncomplicated LC.

Multicenter Study Controlled Clinical Trial
The LINX® reflux management system: confirmed safety and efficacy now at 4 years.
Sphincter augmentation with the LINX® Reflux Management System is a surgical option for patients with chronic gastroesophageal disease (GERD) and an inadequate response to proton pump inhibitors (PPIs). Clinical experience with sphincter augmentation is now available out to 4 years. ⋯ Sphincter augmentation with the LINX Reflux Management System provided long-term clinical benefits with no safety issues, as demonstrated by reduced esophageal acid exposure, improved GERD-related quality of life, and cessation of dependence on PPIs, with minimal side effects and no safety issues. Patients with inadequate symptom control with acid suppression therapy may benefit from treatment with sphincter augmentation.
