Background Cancer, perforation and bleeding in the bypassed stomach after RYGBP are rare but serious complications that require early diagnosis. Our goal was to perform a Roux-en-Y gastric bypass (RYGBP) whereby the traditional endoscopic and x-ray study of the bypassed stomach was possible, and at the same time obtain a good weight loss, similar to the standard RYGBP. We developed the RYGBP-on-Vertical banded gastroplasty (RYGBP on VBG), where a Goretex[TM] band surrounds the gastro-gastric outlet. Methods From June 2002 to September 2005, 128 patients, 94 female and 34 male, with age 50.5+-14.8 SD years, BMI 51.6+-7.2 SD kg/m.sup.2, and %EW 117.9+-33.5 SD underwent RYGBP on VBG via an open approach. Radiological and, if necessary, endoscopic study has been carried out at 6 months, 1 year and then annually postoperatively. Results Two cases of anastomotic ulcer were detected, but no case of infection of the prosthetic material was found. Preoperative BMI fell from 51.6+-7.2 to 38.1+-6.6 after 6 months, to 35.0+-7.1 after 1 year, to 34.4+-6.1 after 2 years, and to 33.2+-5.5 after 3 years. Conclusion RYGBP on VBG was effective the weight loss curve, compared to standard RYGBP, is similar, while allowing the traditional x-ray and endoscopy of the bypassed stomach and thus the biliary tract.
