Diverticular Disease of the Stomach and Small Bowel
Introduction
Diverticula are saclike mucosa-lined pouches that protrude from a tubular structure (see also Definition of Diverticular Disease ). Diverticula rarely involve the stomach but are present in the duodenum in up to 25% of people. Most duodenal diverticula are solitary and occur in the second portion of the duodenum adjacent to or involving the ampulla of Vater (periampullary). In the remainder of the small bowel (jejunum and ileum), diverticula occur in up to 5% of patients, occur most commonly in the jejunum, and are more common among patients with disorders of intestinal motility. Meckel Diverticulum occurs in the middle to distal ileum. Most diverticula of the stomach and small bowel are asymptomatic and are detected incidentally. Complications of diverticula include Overview of Gastrointestinal Bleeding ,
