Revisional Surgery for Severe Obesity with Fascia Banded Stoma Roux-en-Y Gastric Bypass.

The fascia banded stoma Roux-en-Y gastric bypass (RYGBP) has been effective both as a primary and revision operation for severe obesity or failure of another operation. Since May 1984, 361 primary and 100 revisional fascia banded RYGBP operations have been reported. Weight loss achieved a mean body mass index of 30 for primary and 31 for revision patients at most recent follow-up of 3-6 years (mean 4.3 years) postoperatively. Mean overweight was 28% for primary, and 34% for revision patients. Eighty percent of primary and 79% of revision patients were within 50% of ideal weight. Revision rates for these patients were 0 for primary and 1% for revision patients. Operative mortality was 0 for primary and 1% for revision patients. Since morbidity and mortality, although low, are higher for revision than primary surgery, it is important to use an effective primary operation.
