Does tissue ischemia actually contribute to leak after sleeve gastrectomy? An experimental study.

Background: Staple line leak, although rare, is among the most common postoperative complications after sleeve gastrectomy (SG) and usually occurs in the gastroesophageal (GE) junction. Increased intragastric pressure, regional ischemia, and technical failure of stapling devices have been reported as the main risk factors of postoperative leak. The aim of this study was to evaluate the impact of ischemia and intraluminal pressure in leak appearance.

C-reactive protein, white blood cells, and neutrophils as early predictors of postoperative complications in patients undergoing laparoscopic sleeve gastrectomy.

Background: Early detection and treatment of complications after laparoscopic sleeve gastrectomy (LSG) are mandatory. This study aimed to evaluate C-reactive protein (CRP), white blood cell (WBC) count, and neutrophil (NEU) count in relation to the early diagnosis of major surgical complications after LSG.

Methods: A prospective study of 177 patients who underwent LSG during 2008-2011 was performed.

Novice surgeons versus experienced surgeons in laparoendoscopic single-site (LESS) surgery: a comparison of performances in a surgical simulator.

Introduction: During the past years, there has been increasing interest in simulation-based training of technical skills especially in laparoscopy. The purpose of this study was to compare the performances of novice and experienced laparoscopic surgeons on a LESS simulator.

Methods: The study recruited 20 surgeons classified into two groups: group NS consisted of ten residents without any laparoscopic experience, and group ES consisted of ten surgeons with experience in conventional laparoscopy (performed >90 laparoscopic cholecystectomies) but without any experience in LESS surgery.

Reinforcing the staple line during laparoscopic sleeve gastrectomy: prospective randomized clinical study comparing two different techniques. Preliminary results.

Background: Sleeve gastrectomy involves the creation of small gastric reservoir based on lesser curvature of the stomach, which is fashioned by a longitudinal gastrectomy that preserves the antrum and pylorus together with its vagal innervation. The main complications in the early postoperative course are bleeding and gastric leak. In order to reduce these complications the staple line can be reinforced in many different ways.

Routine abdominal drains after laparoscopic sleeve gastrectomy: a retrospective review of 353 patients.

Complications after laparoscopic sleeve gastrectomy (LSG) are usually silent and difficult to interpret. Our purpose was to evaluate the utility of routine placement of intraperitoneal drains at the end of LSG in detection and management of postoperative complications. This is a retrospective study of all patients that underwent LSG by a standard operative team in a 3-year period.
