Bowel diversion surgery allows stool to safely leave the body when — because of disease or injury — the large intestine is removed or needs time to heal. Bowel is a general term for any part of the small or large intestine.
Some bowel diversion surgeries — those called ostomy surgery — divert the bowel to an opening in the abdomen where a stoma is created. A surgeon forms a stoma by rolling the bowel's end back on itself, like a shirt cuff, and stitching it to the abdominal wall. An ostomy pouch is attached to the stoma and worn outside the body to collect stool.
Other bowel diversion surgeries reconfigure the intestines after damaged portions are removed. For example, after removing the colon, a surgeon can create a colonlike pouch out of the last part of the small intestine, avoiding the need for an ostomy pouch.
Cancer, trauma, inflammatory bowel disease (IBD), bowel obstruction, and diverticulitis are all possible reasons for bowel diversion surgery.
Bowel diversion surgeries affect the large intestine and often the small intestine.
The small intestine runs from the stomach to the large intestine and has three main sections: the duodenum, which is the first 10 inches; the jejunum, which is the middle 8 feet; and the ileum, which is the final 12 feet. Bowel diversion surgeries only affect the ileum.
The large intestine is about 5 feet long and runs from the small intestine to the anus. The colon and rectum are the two main sections of the large intestine. Semisolid digestive waste enters the colon from the small intestine. Gradually, the colon absorbs moisture and forms stool as digestive waste moves toward the rectum. The rectum is about 6 inches long and is located right before the anus. The rectum stores stool, which leaves the body through the anus. The rectum and anus control bowel movements.
Several surgical options exist for bowel diversion.
Some people only need a temporary bowel diversion; others need permanent bowel diversion.
The type, degree, and location of bowel damage, and personal preference, are all factors in determining which surgery is most appropriate. For example, people whose disease affects the ileum are poor candidates for ileoanal reservoir surgery or continent ileostomy because of the increased risk of disease recurrence and the need for pouch removal.
Discussing treatment options with a doctor and seeking the advice of an ostomy nurse — a specialist who cares for people with bowel diversions — are highly recommended.
Although bowel diversion surgery can bring great relief, many people fear the practical, social, and psychological issues related to bowel diversion. An ostomy nurse is trained to help patients deal with these issues both before and after surgery. People living with an ostomy or who need bowel diversion surgery may also find useful advice and information through local or online support groups.
The National Institute of Diabetes and Digestive and Kidney Diseases conducts and supports basic and clinical research into many digestive disorders, including inflammatory bowel disease and diverticular disease.
Participants in clinical trials can play a more active role in their own health care, gain access to new research treatments before they are widely available, and help others by contributing to medical research. For information about current studies, visit www.clinicaltrials.gov/

The National Digestive Diseases Information Clearinghouse (NDDIC) is a service of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). The NIDDK is part of the National Institutes of Health of the U.S. Department of Health and Human Services. Established in 1980, the Clearinghouse provides information about digestive diseases to people with digestive disorders and to their families, health care professionals, and the public. The NDDIC answers inquiries, develops and distributes publications, and works closely with professional and patient organizations and Government agencies to coordinate resources about digestive diseases.
Publications produced by the Clearinghouse are carefully reviewed by both NIDDK scientists and outside experts. This publication was reviewed by Victor W. Fazio, M.D., chairman, Department of Colorectal Surgery, Cleveland Clinic Foundation, and Linda K. Aukett, advocacy chair, United Ostomy Associations of America, Inc.
