A Technique for Converting the Roux-en-Y Gastric Bypass to a Modified Biliopancreatic Diversion

Our group has performed the Roux-en-Y gastric bypass (RYGB) in 1450 patients since 1983: 805 patients had primary operations, and 645 were converted from previous gastroplasty procedures, i.e. horizontal gastroplasty, vertical banded gastroplasty, and gastrogastrostomy. Within the last 2 years, 38 patients who failed the RYGB were converted to a modified biliopancreatic diversion (BPD) using a technique that did not require dismantling a major portion of the original gastric exclusion. A 24-month follow-up has demonstrated a significant and sustained weight loss in all patients. In addition, the modified BPD completely eliminated the problem of reflux bile gastritis in those patients with a short Roux-en-Y jejunal limb.
