Pharmacobezoar: An Unusual Cause of Large Bowel Obstruction.

Large bowel obstruction (LBO) is an abdominal emergency with high morbidity and mortality rates if left untreated. LBO is four to five times less frequent than small bowel obstruction (SBO) and the causes of LBO and SBO differ substantially. Colonic malignancy remains the most common cause of LBO (> 60%). Additional causes of LBO include entities such as diverticulitis, colonic volvulus, and adhesion. Herein we present a case of acute LBO caused by pharmacobezoar.
