Laparoscopic Sleeve Gastrectomy: Investigation of Fundus Wall Thickness and Staple Height—an Observational Cohort Study

Background Staple line leakage is a well-known complication after laparoscopic sleeve gastrectomy (LSG). Gastric wall thickness and the staple height may be determining factors for the occurrence of insufficiencies. To investigate this problem, an observational cohort study was carried out. Investigation concentrated on the gastroesophageal junction close to the angle of His, since this area is at highest risk for a leakage.
