Migration of Over-the-scope Clip Resulting in Anal Pain and Obstructed Defecation

Abstract

Iatrogenic perforation is a known and feared complication of diagnostic and therapeutic colonoscopy. Specific locations in the gastrointestinal tract, such as the jejunum, have a higher risk of perforation owing to its difficult anatomical position. Over-the-scope clips have recently been used for the management of these perforations. We present the case of a 40-year-old male patient treated with over-the-scope (Ovesco(®), Ovesco Endoscopy AG, Tübingen, Germany) clips for an iatrogenic postpolypectomy perforation with subsequent anal pain and inability to evacuate stool occurring as a result of the migration of the clip, followed by a review of the literature.
