Internal Hernias After Laparoscopic Gastric Bypass (IHafterLRYGB)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The main goal of this study is to describe the trends in the incidence rate of internal hernia presentation after different modifications of the mesenteric closure technique after primary laparoscopic Roux-en-Y gastric bypass (RYGB) surgery from 1997-2009.
Closure technique for mesocolic defect: 1- non-closure, 2- running with absorbable material, 3- interrupted with non-absorbable material, and 4- running with non-absorbable [ Time Frame: throughout follow-up ]
recurrence of symptomatic mesocolic internal hernia [ Time Frame: throughout follow-up ]
