The GaBP Ring Device For Banding The Pouch in Gastric Bypass and Sleeve Gastrectomy Operations Bariatec Corporation P.O Box 4257 Palos Verdes Peninsula, CA

GaBP Ring The GaBP Ring is a prefabricated, caliberated and sterilized silicone coated implantable device that is designed specifically to control the reservoir capacity in gastric operation for obesity.

The Gastric Bypass operation is the Gold standard of weight loss operations

Reports show that % of patients do not achieve successful * weight loss in the short term 1-3yrs after the operation. Reports also show that this rate increases to 25-40% in patients followed longer than three years because of weight regain. *Successful weight loss; > 50% excess weight loss and or attainment of a BMI<35. The inadequate weight loss and weight regain observed in the gastric bypass operation have been attributed mostly to the increase in the gastric reservoir size due to dilation of the pouch, stoma and the proximal small bowel.

Non Banded Gastric bypass Dilated stoma converts the pouch and the proximal small bowel into a neo-pouch that can accommodate as much as the initial Stomach. Causing inadequate weight loss and weight regain after gastric bypass Non Banded dilated Stoma and proximal Small bowel become part of neopouch

GaBP Ring Device Placement of a prosthetic device around the pouch to function as the stoma has been shown to not only reduce the pouch size but also to prevent the development of this large gastric reservoir.

Banding the pouch Banding the pouch creates a smaller pouch Banding the pouch minimizes pouch dilatation

GaBP Ring Device Reports have shown increased eight loss in more patients and less weight regain with the prevention of the formation of this large gastric reservoir. Since Roux-en-Y Gastric Bypass is primarily a restriction operation, just as with VBG, it is important that the outlet of the pouch does not stretch. ( E.Mason. Obesity Surgery 1994;4:66-72)

Based on these reports, MacLean in 1997 stated that: The most promising technique based on a large series at this time is that described by Capella and Capella Banded Gastric Bypass MacLean J Am Coll Surg 97;185:1-7

Banding the Gastric Bypass Operation Fisher after an in depth review concluded in 1999 that: Long-term results suggest that a silastic ring encircling the stomach pouch proximal to the gastroenterostomy may improve the outcome following gastric bypass surgery, resulting in more weight loss by a greater number of patients sustained for a longer time Fisher BL, Barber AE, Eur J Gastroenterol Hepatol 1999; 11:93-97
