BACKGROUND: Three hundred and forty-five patients who underwent urgent colonoscopy for acute hematochezia during the past 20 years (from 1976 to 1995) were retrospectively analyzed. METHODS: Urgent colonoscopy was defined as endoscopy performed within 24 h after a bleeding episode. Preparation was initially minimal with a water or glycerine enema. Recently, however, polyethylene glycol is used. RESULTS: The overall diagnostic accuracy for bleeding site detection was 89.1% (307 cases). Successful insertion was made to the ileocecal region in 193 cases (55.9%). The disease most frequently discoverd by urgent colonoscopy was transient ischemic colitis (62 cases). Negative urgent colonoscopy specimens (18 cases) were later diagnosed by other methods as being small intestinal bleeding foci. In 10 cases, initial colonoscopy failed to detect the bleeding foci. Endoscopic hemostasis was performed in 48 cases. Permanent hemostasis succeeded in 32 cases (66.7%). Complications of urgent colonoscopy were fever after the examination (22 cases) and hypotension during endoscopy (7 cases). CONCLUSION: Urgent colonoscopy is considered to be a safe and useful examination for acute lower gastrointestinal bleeding and hemostasis. Copyright 2000 S. Karger AG, Basel
