BACKGROUND: Roux-en-Y gastric bypass (RYGBP) is rarely performed in Italy because it involves gastric exclusion. RYGBP with the stomach partitioned by an adjustable gastric band has been previously described. We have developed a functional RYGBP (FRYGBP) where an adjustable band allows access from a stapled gastric bypass pouch into the distal stomach. METHODS: From October 2001 to May 2002, 16 patients underwent FRYGBP. A 30-cc vertical gastric pouch was fashioned by a 25-mm circular and 90-mm four-row stapler as in the Mason VBG. A hand-sewn retrocolic gastroenterostomy with 150-cm Roux and 30-cm afferent limbs completed the operation. The pouch outlet was encircled distal to the gastrojejunostomy by a non-inflated adjustable gastric band. The bands were inflated at 1 month during barium swallow, to demonstrate occlusion of the gastro-gastric outlet and patency of the gastrojejunostomy. RESULTS: There was no operative mortality. After 1 year, mean percent excess BMI loss (%EBMIL) was 71.2 +/- 16.2% (SD), and gastroscopy of the bypassed stomach was possible on 81% of the patients. There were three asymptomatic late complications (19%): two band erosions, converted to RYGBP, and one stenosis of the gastro-gastric outlet. CONCLUSION: FRYGBP thus far has been effective and allows the study of the excluded stomach. This ongoing study will undergo long-term evaluation.
