Does Antrum Size Matter in Sleeve Gastrectomy? Randomized Study

This study was conducted from January 2015 to November 2017 in the Department of General and Emergency Surgery of "A. Rizzoli" Hospital in Lacco Ameno (Naples, Italy). All the procedures were performed by the same surgeon. Morbid obesity was preoperatively diagnosed according to the International Federation for Surgery of Obesity (IFSO) guidelines (1). Patients were randomized into 2 groups: Group A (dissection starts at 2 cm proximally to the pylorus and continued along the greater curvature to the left crus) and Group B (dissection starts at 6 cm proximally to the pylorus and continued along the greater curvature to the left crus). Results were obtained at 1 and 2 years follow-up.
