Gallstone in rectum causing mechanical large bowel obstruction: A case report and literature review

An 87 y/o lady initially presented with a fall and urinary retention, with no abdominal pain or symptoms of obstruction. She proceeded to develop mechanical large bowel obstruction 10 days following her admission. CT confirmed the presence of gallstones in the gallbladder and a large laminated calculus in the rectum with colonic distension up to the anal verge. An examination under anaesthetic was performed which confirmed anal stenosis and the presence of a large stone obstructing the anorectal junction with no evidence of malignancy.
