A stricture is a narrowing of the intestinal diameter or lumen which can lead to an obstruction of
Strictures of the large intestine may be caused by cancer, diverticulitis, ischemia (poor blood flow),
Crohns disease and ulcerative colitis. Strictures of the small intestine may also be caused by
cancer, Crohns disease and ischemia.
- Abdominal distention
- Narrowed caliber stool
Some strictures may be dilated and "opened up" with a specialized balloon dilator that can be
inserted through a colonoscope. Strictures of the small bowel secondary to Crohns disease may
be "opened up" surgically without resecting the intestine (strictureplasty) which preserves
the amount of intestine. Patients with strictures secondary to diverticulitis and colon cancer
warrant an operation which we typically perform laparoscopically.
