Core Tip

Core tip: In this retrospective study a novel endoscopic over-the-scope-clip (OTSC) was evaluated for the treatment of severe gastrointestinal bleeding, perforation and fistula. 101 OTSCs were applied in 84 patients with a primary clinical success in 75/84 patients for all applications corresponding to 89%. Severe bleeding was successfully treated in 35/41 patients with upper gastrointestinal (GI) bleeding (85.36%) and in all 3 patients with severe lower GI bleeding. Technical success of perforation closure was 100% while clinical success was seen in 4/7 cases (57.14%) due to attendant circumstances unrelated to the OTSC. Technical and clinic success was achieved in 18/18 patients for the prevention of secondary perforation or bleeding after endoscopic mucosal resection and endoscopic submucosal dissection and in 3/3 fistula closures. Two application-related complications were seen. This largest single center experience published so far confirms the high value of the OTSC for the endoscopic treatment of GI emergencies and complications.
