Sigmoid looping is not always benign

Abstract

Colonoscopy is a daily procedure that has limited risk if carried out by skilled endoscopists. Unexpected turn of events during the procedure requires careful consideration of the patient's underlying medical or surgical history. Here, we present a case of inability to withdraw the colonoscope after the completion of distal colonic intubation owing to an overseen surgical defect related to inguinal hernia in which entrapment of the colonoscope took place.
