Laparoscopic mini-gastric bypass versus laparoscopic Roux-en-Y gastric bypass in redosurgery after failed vertical banded gastroplasty with long gastric pouch

Authors

Abstract

Background
Up to 50% of patients who undergo vertical band gastroplasty (VBG) experienced weight regain or complications, like band erosion or slippage, within 5–10 years of the procedure, the aim of the study to evaluate laparoscopic mini-gastric bypass versus laparoscopic Roux-en-Y gastric bypass as a redosurgery after failed VBG.
Patients and methods
We analyzed the data of 102 patients (38 males and 64 females) underwent revisional surgery after failed VBGs from July 2021 to August 2022, with mean age 45.92 years, follow up for 1 year in Ain Shams University Hospitals.
Results
The mean hospital stay was 1.8 days (1–4 days), 2.9 days (2–7 days) in Redo laparoscopic mini gastric bypass (R-LMNGB) and Redo laparoscopic roux en Y gastric bypass (R-LRYGB) respectively. Postoperative BMI after 1 year 31.16±27.83 and 31.94±3.69 in R-LMNGB and R-LRYGB, respectively, %EWL show significant difference between two groups after 3 months and 1 year. Postoperative complications rates were 3.92% in R-LRYGB.
Conclusions
R-LMNGB after failed VBG has almost the same results of R-LRYGB as regard weight loss, improvement of obesity-related comorbidities with less operative time, hospital stay, less anastomosis, and complications.
