Abstract

Background

Adjustable gastric banding (AGB) and vertical banded gastroplasty (VBG) have been extensively used to treat morbid obesity. Patients with insufficient weight loss or complications may require surgical revision. The laparoscopic Roux-en-Y gastric bypass (LRYGBP) is one of the most common procedures currently used for revision. The aim of the study was to analyze surgical outcomes of 30 consecutive patients who underwent revision to LRYGBP in a 2-year period.

Methods

The prospectively constructed database and the medical records of all patients undergoing revision to LRYGBP were reviewed. Demographics, surgical details, results, and complications were analyzed.

Results

There were 23 women and seven men with a mean age of 41.1 ± 9.7 years (r = 25-61). Mean body mass index (BMI) was 40.0 ± 7.5 kg/m2 (r = 27.2-65.2). Initial operation was AGB in 24, VBG in five, and both in one patient. In ten patients, the band had been removed before revision, in 13 cases, band removal and LRYGBP were performed in one surgical intervention, and in two patients, it was performed in a two-step surgery. There were two conversions to open surgery. Five patients presented major surgical complications. Hospital stay averaged 5.1 days (r = 3-25). Mean percent excess body weight loss at 6 and 12 months was 61.7 ± 27.5 and 81.2 ± 20.5 kg/m2, respectively. Mean percent low body mass index at 6 and 12 months was 22.5 ± 9.1 and 29.1 ± 11.4 kg/m2, respectively.

Conclusions

LRYGBP as a revision procedure is feasible in most patients. Surgical complications are more frequent.
