Laparoscopic Roux-en-Y Gastric Bypass for Failed Vertical Banded Gastroplasty.

Zakaria, Mahmoud; Elhoofy, Ahmad

BACKGROUND Although the vertical banded gastroplasty (VBG) is effective in achieving weight loss without metabolic side effects during the first few years, late failures cause weight regain in about 20% of the patients. The laparoscopic Roux-en-Y gastric bypass (LRYGB) is the procedure of choice to convert a failed VBG. MATERIALS AND METHODS Between August 2014 and June 2016, 37 patients (23 females and 14 males) underwent revisional LRYGBs after failed VBGs. Thirty-four patients had open VBGs and two patients had laparoscopic butterfly gastroplasties. These patients completed follow-ups of at least 1 year. RESULTS The median operating time was 164 min (range 132-246), and the mean length of the hospital stay was 2.4 days (range 2-7). The mean body mass index (BMI) of the study group was 42.5 kg/m2, while the mean BMI and the percentage of excess body weight loss (%EBWL) for the patients 6 months after the operation were 31.7 kg/m2 and 52.1%, respectively. The mean BMI and %EBWL for the patients 1 year after the operation were 29.5 kg/m2 and 67.7%, respectively. There were neither intraoperative complications nor postoperative mortalities, but the overall complication rate was 22% (eight patients). CONCLUSION An LRYGB following a VBG is technically challenging, but safe, with low morbidity and mortality rates. Moreover, a revisional LRYGB provides excellent weight loss results.
