The surgical technique of the Fobi-Pouch operation for obesity (the transected silastic vertical gastric bypass).

The Fobi-Pouch operation (FPO) for obesity is the product of clinical trials, more than 15 years of personal clinical experience and information gathered from publications, scientific meetings, and personal communications with other bariatric surgeons. The essence of the operation is the small vertical pouch (< 25 ml), an externally supported stoma, the interposed Roux-en-Y limb, the gastrostomy and the bypassed stomach marker to facilitate percutaneous transabdominal access to the bypassed segment. Patients undergoing this operation are usually given bowel prep the day before the operation, admitted the morning of the operation and started on subcutaneous heparin, prophylactic antibiotic and hydration. Antithrombotic sequential compression devices are regularly used. The hospital stay is usually 4 days. Our results and those of other surgeons who have used this modification substantiate the rationale for the modifications entailed in the FPO. Our longer-term experience and results are being compiled for publication.
