Stricture Rates After Gastric Bypass with Hand-Sewn Anastomosis

Abstract

Background: Anastomotic strictures at the gastrojejunal anastomosis (GJA) are relatively common after a laparoscopic Roux-en-Y gastric bypass (LRYGB). There are three different ways to perform a GJA: circular stapled (CS), linear stapled (LS), and hand-sewn (HS). The CS technique provides the most standard diameter, and the LS and HS techniques can be standardized by using a bougie to calibrate the diameter of the anastomosis. However, they can all become strictured. This study examines the stricture rate of a hand-sewn GJA over a 4-year period. Methods: A prospectively maintained database was used to retrospectively evaluate patient outcomes at our bariatric center. This database was evaluated for strictures. The gastric bypasses were performed over a 4-year period by a single surgeon. The technique remained standard over the study period. This was a two-layered HS anastomosis with four different sutures of an absorbable suture (2.0 VICRYL®). Inclusion criteria were primary laparoscopic gastric bypasses....
