ABSTRACT
Obstruction of the large intestine is a serious medical problem requiring urgent attention and intervention. A variety of conditions can result in bowel obstruction, most commonly colorectal cancer, volvulus, and diverticular disease. The onset of obstruction may be gradual, as seen in patients with sigmoid cancer, or acute, as in those with sigmoid volvulus. Symptoms of obstruction include abdominal pain and distension and obstipation. Recent advances in medical care have changed the therapeutic approach to patients with obstruction, including more frequent use of one-stage surgical procedures and nonoperative methods for palliation. An understanding of the etiology of large bowel obstruction and the methodology for appropriate intervention is necessary to assure optimal outcome.
