Intramural Hematoma Causing Hematochezia After Colonoscopy With Polypectomy

Aleksandar Gavrić et al. ACG Case Rep J. .

Abstract

Intramural hematoma of the colon is a rare complication of colonoscopy. We present a case of a 78-year-old woman on warfarin who presented with hematochezia and hypotension due to intramural hematoma of the sigmoid colon after colonoscopy with polypectomy of small polyps in the right colon.
