Short Gastric Pouch for Laparoscopic Conversion of Failed Band to Roux-en-Y Gastric Bypass

Abstract

BackgroundLaparoscopic gastric banding (LGB) is associated with high rate of failure (Stenard and Iannelli. World J Gastroenterol; 21:10348-57 2015, Lazzati et al. Ann Surg. 2016). In case of failure, conversion to Roux-en-Y gastric bypass (RYGB) is preferred (Noel et al. Surg Obes Relat Dis;10:1116-22; 2014, Schneck et al. Surg Obes Relat Dis;12:840-8, 2016).MethodsWe present the case of a 63-year-old woman with a BMI of 57\xa0kg/m2 who underwent LGB in 2011. In 2015, she consulted for intolerance of the banding and weight regain, with a BMI of 52. The gastric band was removed, and 6\xa0months later conversion to RYGB was performed.ResultsThe main technical problem of conversion of LGB to RYGB is where to staple the stomach, either below or above the band-related scarring tissue. Stapling below the band in a fresh non-scarring area often results in the creation of a large pouch; furthermore, the vertical part of the pouch stapling is done on scarring tissue, with a risk of leak. Stapling above the band leaves a very small part of stomach and may be technically challenging. The present video shows the conversion of LGB to RYGB. The hiatal region is dissected, and a small pouch stapling above the band-related scarring tissue is fashioned. An RYGB with a 150-cm alimentary limb and a 50-cm biliopancreatic limb is confectioned.ConclusionsFor conversion of LGB to RYGB, a small gastric pouch above the gastric band scar tissue is confectioned, after dissection of the hiatal region and abdominal esophagus. The small pouch ensures the restriction, and all the stapling and suturing are done on healthy, fresh tissue.
