Crohn's disease has shown increased frequency in Korea. When unresponsive to medical therapy, intestinal stricture, a serious complication of Crohn's disease, sometimes requires surgical resection. However, surgical therapy has many problems because the stricture tend to recur frequently. Recently, endoscopic therapy such as bougienation or balloon dilatation has been used in treatment of intestinal stricture, because of its inexpensiveness, simplicity and safety. Combined steroid injection therapy using has shown more effective outcome than endoscopic dilatation alone by suppression of wound healing and reduction of fibrosis. We report a case of complicated rectal stricture in a patient with Crohn's disease, which dilated successfully using injection of triamcinolone following bougienation.
