Restrictive and Malabsorptive Procedure :
The Silastic® Ring Gastric Bypass is a banded pouch RYGBP. A Silastic® ring is placed around the vertically constructed gastric pouch above the anastomosis between the pouch and intestinal Roux limb. The band controls stomach size by prevention of dilatation of the gastric pouch outlet, and is thought to provide better long-term control of the rate of emptying of the pouch and caloric intake. This procedure also includes placement of a gastrostomy tube for decompression of the distal stomach. A radio-opaque ring marker may be placed around the gastrostomy site to facilitate future percutaneous access to the distal stomach. A small percentage (5%) of patients may have band erosion or obstruction, necessitating surgical band removal.
