Laparoscopic appendectomy in complicated appendicitis with compromised appendix base: a retrospective cohort study.

Background: Patients with compromised appendix base constitute a subgroup of patients with complicated appendicitis, and there is few available information.

Objective: To study the frequency of stump leaks and fistulae in patients with complicated appendicitis with compromised stump.

Method: This is an observational, retrospective study of patients that underwent laparoscopic appendectomy with compromised appendix stump.

Peroral endoscopic myotomy as treatment for Zenker's diverticulum (Z-POEM): a multi-center international study.

Background: Peroral endoscopic myotomy for the treatment of Zenker's diverticulum (Z-POEM) is a novel technique that has been described in several recent reports. This method utilizes the third space (submucosal layer) to create a tunnel to facilitate complete visualization of the septum and hence cutting it entirely. Conventional endoscopic septotomy carries the risk of recurrence due to incomplete visualization of the septum.

Laparoscopic cholecystectomy after endoscopic treatment of choledocholithiasis: a retrospective comparative study.

Patients with combined choledocholithiasis and cholecystitis require treatment of both diseases. The aim of our study was to analyze perioperative results of next-day (< 24 h) vs. early (> 24 h) laparoscopic cholecystectomy (LC) after endoscopic clearance of common bile duct stones.

Enhanced recovery after surgery protocol allows ambulatory laparoscopic appendectomy in uncomplicated acute appendicitis: a prospective, randomized trial.

Background: Previous observational studies have demonstrated the safety of discharging patients after laparoscopic appendectomy within the same day without hospitalization. The application of Enhanced Recovery After Surgery (ERAS) guidelines has resulted in shorter length of stay, fewer complications, and reduction in medical costs. The aim of this study was to investigate if ERAS protocol implementation in patients with acute uncomplicated appendicitis decreases the length of stay enough to allow for ambulatory laparoscopic appendectomy.

Intraoperative endoscopy prevents technical defect related leaks in laparoscopic Roux-en-Y gastric bypass: A randomized control trial.

Background: Postoperative anastomotic leaks, bleeding and stenosis are major causes of morbidity after laparoscopic Roux-en-Y gastric bypass (LRYGB). Retrospective studies suggest that intraoperative endoscopy reduces the incidence of these complications.

Methods: We conducted a prospective randomized controlled trial in a single institution between March 2013 and January 2016.
