To assess the application value of emergency colonoscopy in the diagnosis and treatment of acute colorectal obstruction. A total of 459 patients with acute colorectal obstruction received emergent colonoscopy from July 2002 to July 2010. The safety and effective rates were analyzed. The diagnostic rate of successful emergency colonoscopy was 100% (459/459) without any complication. Colorectal cancer were found in 71.3% cases (327/459), volvulus of sigmoid in 11.3% (52/459), diaphragmatocele in 0.4% (2/459), megacolon congenitum in 0.6% (3/459), fecal obstruction in 2.7% (12/459) and none in 13.7% (63/459). The therapeutic rate of colonoscopy was 83.2% (385/459). There were colorectal cancer (n = 327), volvulus of sigmoid (n = 52) and megacolon congenitum (n = 3). The successful treatment rate was 95.8% (369/385) and the complication rate 1.4% (5/385). Among all colorectal cancers, 93.9% (307/327) received endoscopic drainage (mental stents or drainage tube) so as to avoid emergency operations and stoma. And 232 cases underwent phase I operation and another 75 cases received chemotherapy or supportive treatment. Emergency colonoscopy is an effective, safe, minimal invasive approach for diagnosing and managing acute colorectal obstruction.
