Gastric Bypass Revisions
The gastric bypass revisions process can be finally fail for many reasons, the most common of which is gastric pouch dilation, where the stomach enlarge in the size over time. Of course, as the stomach gets bigger, the patient is able to eat more. During the primary gastric bypass revisions process, the stomach is reduced to about 20% of its original size.
But the stomach is a very flexible organ and, with improper aftercare, can increase in size. If pouch dilation does, in fact, occur it normally becomes apparent many years after the procedure.Other less common reasons for a revision can include a stricture, where scar tissue partially blocks the opening to the small intestine and serious dumping syndrome. The gastric bypass, like all bariatric surgery procedures can be revised. Since the gastric bypass affects both the stomach and small intestine, there are fewer options to definitively restore the previous function than the gastric banding or sleeve. The most commonly performed gastric bypass revision is the duodenal switch, which itself is sometimes used as a primary procedure. The duodenal switch essentially reactivates the portion of the stomach that was cut away. The duodenal switch procedure maintains the bypass’s combination of restriction and malabsorption.
