Ovesco system for treatment of postpolypectomy bleeding after failure of conventional treatment

The clip Ovesco (Ovesco, Tübingen, Germany) is a novel endoscopic method for mechanical compression of tissue in the gastrointestinal tract. The indications for treatment are closure of perforations and fistulas and control of bleeding in which the conventional endoscopic treatment has failed. We report two cases about the use of an Ovesco (over-the-scope clip, OTSC) system to control persistent bleeding postpolypectomy after failure of usual treatment.
