Abstract
The optimal distance between the starting point of gastric transection and the pylorus during laparoscopic sleeve gastrectomy (LSG), which can be referred to as the distance from pylorus (DFP), is controversial. No consensus exist for what DFP is considered antral preservation, and what DFP is considered antral resection. Some surgeons prefer shorter DFP to maximize excess weight loss percentage (EWL%), while others prefer longer DFP because they believe that it shortens length of stay (LOS) and protects against leaks, prolonged vomiting, and gastroesophageal reflux disease (GERD). We sought to compare 6-cm DFP and 2-cm DFP in postoperative outcomes. In addition, we sought to evaluate the magnitude of any observed benefit through number needed to treat (NNT) analysis.
