Novel Technique of Distal Roux-en-Y Gastric Bypass for Insufficient Weight Loss After Primary Procedure: Personal Experience and Primary Results at 12 Months.

PURPOSE: In the literature, up to 20% of patients present a failure of weight loss after primary Roux-en-Y gastric bypass (RYGBP) or other restrictive procedures. Our aim is to describe the midterm results of our novel technique of distal Roux-en-Y gastric bypass (DRYGBP) as a revisional procedure.

MATERIALS AND METHODS: We performed our DRYGBP in 21 patients. The length of the common channel was 100 cm, whereas the lengths of the alimentary and the biliopancreatic limbs were 2/3 and 1/3 of the remaining bowel, respectively. We created 2 subgroups, a "revisional" group after failed restrictive procedures and a "distalization" group after failed RYGBP.

RESULTS: The mean excess weight loss at 12 months in the "revisional" group (10 patients) was 67.8% and in the "distalization" group (11 patients) 57.1%. We did not experience any mortality nor severe morbidity rates.

CONCLUSIONS: In our experience, our DRYGBP differentiated procedure seems to be effective at 12 months.
