Abstract:
A 68-year-old woman presented with vomiting and upper abdominal pain. Computed tomography (CT) and endoscopic ultrasound revealed a stone in the peripapillary diverticulum, with biliary dilation due to extrinsic compression, consistent with Lemmel's syndrome. Although the symptoms initially improved, they worsened 2 days later. The CT imaging showed migration of the diverticular stone to the small intestine portion corresponding to pelvic region, resulting in bowel obstruction. The patient underwent laparoscopic stone removal and had a smooth recovery. This report presents a rare case of bowel obstruction caused by migration of a stone originating from a duodenal peripapillary diverticulum, with detailed follow-up of the clinical course.
