Abstract

Background Vertical banded gastroplasty (VBG) has a relatively high failure rate in the long run, requiring revisional surgery in 30-65%. A common conversion option is to Roux-en-Y gastric bypass (RYGB), which can be performed laparoscopically or open. Current literature contains small cohorts and inconclusive results. Therefore, we set out to compare our series of open and laparoscopic VBG to RYGB conversions.Methods All conversions performed between 1996 and 2020 were included. Patients were divided into 3 groups based on conversion indication: weight recurrence (group 1), excessive weight loss (group 2), and eating/pouch difficulties (group 3). The primary outcome was postoperative complications according to the Clavien-Dindo (CD) classification. Secondary outcome was %total weight loss (%TWL) 1 to 5 years after revisional surgery.Results We included 205 patients (84.9% female) of whom 105 underwent laparoscopic and 100 open VBG to RYGB conversion. Twenty-three short-term complications occurred in the laparoscopic group, with 16 >= CD3a. In the open group, 33 complications occurred with 12 >= CD3a. Overall complications were 33.3% in laparoscopic and 64% in open patients. There were no significant differences between the laparoscopic and open group in BMI (p = 0.76) and %TWL (p = 0.694) after 5 years. After 5 years, lost to follow-up was 97% in the open group. Twenty-eight percent of patients who reached follow-up in the laparoscopic group had available data.Conclusions We demonstrate that the overall complication rate is lower in the laparoscopic group compared to the open group. Regarding BMI, an improvement was achieved in both groups after 5 years.
