Laparoscopic Roux-en-Y Gastric Bypass After Failed Vertical Banded Gastroplasty: 2-Year Follow-up of 102 Patients

Background Vertical banded gastroplasty (VBG) is now discarded from being a restrictive procedure for morbid obesity due to its many drawbacks, doubtful efficacy, and lots of post-operative complications. Roux-en-Y gastric bypass (RYGB) is the most commonly performed procedure for VBG revision. So we aimed at reporting our experience in conversional RYGB for a failed VBG. Material and Methods Analyzing follow-up records of 102 patients who underwent revisional RYGB after failed VBG in the period from April 2014 to January 2018. Results A total of 102 laparoscopic revisions of failed VBGs to RYGB were performed. The mean operating time was 161.9 min +/- 29.2 and the mean length of the hospital stay was 1.5 days +/- 1.2. Fourteen patients (13%) developed early post-operative complications (gastrojejunostomy leak 5; bleeding 9). Four patients (4.7%) developed late complications (Port site hernia 2; internal hernia 1; Stomal ulcer 1). The mean BMI pre-RYGB was 46.6 +/- 5.9 kg/m(2), and the mean %EBWL (percent excess body weight lost) of the patients at 12 and 24 months post-revision were 56.2% and 64.3%, respectively. Our patients had immediate post-revision resolution of VBG-related complications like dysphagia and vomiting. We also report improvement in all obesity-related health problems with (75.7%) complete remission rate and (24.3%) partial remission or improvement rate of diabetes mellitus. Conclusion Conversion of VBG to RYGB is a feasible procedure and is associated with acceptable early morbidity rates and reduced lengths of hospitalization also it provides acceptable weight loss and improvement in obesity-related health problems.

Conversion of VBG to RYGB is a viable option with significant improvement in VBG-related complications, providing acceptable weight loss and improvement in obesity-related health problems, such as diabetes.
