Duodenojejunal Bypass and Strictureplasty for Diffuse Small Bowel Crohn’s Disease with a Step-by-Step Visual Guide

Abstract

Lay Summary Crohn’s disease is an inflammatory condition of the intestine with an unknown cause and can result in inflammation, narrowing (stricuture) or penetrating disease (fistula that inflammation goes through the wall of the bowel and into another structure). Unfortunately Crohn’s disease can affect anywhere in the gastrointestinal tract, all the way from the mouth to the anus. Sometimes Crohn’s disease can affect the duodenum, the portion of the small intestine just after the stomach. When Crohn’s disease is in the duodenum and causes narrowing, it is difficult to treat medically, and often needs a surgical intervention. When the narrowing is short, less than a few centimeters, the surgeon can do a strictureplasty which means opening the intestine across the stricture and sewing it back shut in the horitzontal direction to make the opening larger. When the narrowing, or stricture, is longer, then the surgeon may have to connect the stomach to another part of the small intestine (gastrojejunostomy) to avoid or bypass the duodenum, or may have to perform a large reconstructive operation to remove that portion of the small intestine. the challenge is that those operations have significant potential complications associated with them. Therefore, sometimes a bypass operation can be done instead to connect the duodenum to the next part of the small intestine, the jejunum. In this manuscript the authors describe this surgical technique is a 38 year old male with Crohn’s disease who was referred with multiple areas of narrowing in his intestine.
