Abstract

Background: In Roux-Y gastric bypass surgery pouch formation is the most demanding part of the operation. The vagal nerve is usually tempted to be preserved although results reporting beneficial effects are lacking. Dividing the perigastric tissue including the anterior vagal trunk may technically alleviate gastric pouch formation. We evaluated the clinical outcome in patients with and without vagal nerve dissection in patients after Roux-Y gastric bypass (RY-BP). Methods: In this study 40 morbidly obese patients undergoing RY-BP have been included. Patients were divided into two groups according to vagal nerve preservation (Group 1, n∈=∈25) or vagal nerve dissection (Group 2, n∈=∈22). Clinical parameters (weight loss, complications, gastrointestinal symptoms), esophageal endoscopy, and motility data (manometry, pH-metry) and a satiety score were assessed. Serum values of ghrelin and gastrin were measured. Results: All procedures were performed by laparoscopy with a 0% mortality rate. One patient of each groups necessitated redo-laparoscopy (bleeding and a lost drainage). All patients significantly reduced body weight (p∈
