Revision of Failed Vertical Banded Gastroplasty to Non-resectional Scopinaro Biliopancreatic Diversion: Early Experience

Background: The most commonly performed revision operation following failed vertical banded gastroplasty (VBG) is Roux-en-Y gastric bypass, although revision to biliopancreatic diversion (BPD) with duodenal switch is now another common option. We describe the surgical technique for revision of a failed VBG to a non-resectional Scopinaro BPD in a series of patients, as well as the outcome in terms of complications and mean % excess weight loss (%EWL). Methods: A retrospective review was conducted on all patients who underwent revision to BPD at Mercy Bariatrics, Western Australia, between June 2001 and April 2005. This yielded 20 patients who had revision to BPD, 9 of whom had VBG as their initial operation. The mean %EWL was measured at regular intervals postoperatively (3, 6, 12, and 24 months). Results: Mean %EWL at 12 and 24 months was 69.5 and 76.7, respectively. These results are comparable to %EWL after a primary BPD. Nutritional manifestations were found to be the most common of the minor complications. Conclusion: Our technique for revision of a failed restrictive operation to a non-resectional Scopinaro BPD is described. The preliminary results in terms of %EWL and complications are comparable to other revisional malabsorptive operations. Prospective randomized controlled trials are needed to further evaluate effects of revision to a non-resectional Scopinaro BPD and to ensure that the results (in terms of %EWL) are reproducible.
