Treatment of Gastric Bypass

Gastric Bypass Procedure

Smaller Stomach

Using staples, the stomach is divided into two sections – a smaller upper section called the pouch and a larger bottom section. The food goes into the pouch which holds a very little amount, usually about an ounce. Hence, the person eats less and loses weight.

Bypass

A small part of the small intestine (the jejunum) is connected to a small hole in the pouch. The food goes directly from the pouch through the new opening in the small intestine. As a result, fewer calories are absorbed.

Roux-En-Y Gastric Bypass (RGB)

A small stomach pouch is created by stapling part of the stomach together or by vertical banding. This limits the amount of food the patient can eat. A Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the duodenum and the first portion of the jejunum. This causes reduced calorie and nutrient absorption.

Laparoscopy Surgery

Step 1

The surgeon makes 4 to 6 small incisions in the belly.

Step 2

A laparoscope is inserted through one of these cuts and is connected to a video monitor in the operating room to see inside the belly.

Step 3

The surgeon places a band around the upper part of your stomach to separate it from the lower part.

Step 4

This creates a small pouch that has a narrow opening that goes into the larger, lower part of your stomach.

Step 5

The incisions are closed and the surgery does not involve any stapling inside the belly.

Extensive Gastric Bypass (biliopancreatic diversion)

It is a more complicated gastric bypass operation wherein the lower portion of the stomach is removed. The small pouch that remains is connected directly to the final segment of the small intestine, hence, completely bypassing both the duodenum and jejunum.
