Free Intraperitoneal Gallstone: An Unusual Case of Small Bowel Obstruction from Extrinsic Compression.

Laparoscopic cholecystectomy (LC) is preferred in the treatment of symptomatic cholecystolithiasis. Gallstone spillage is not uncommon, and there have been reports of associated complications. We report a case of a free intraperitoneal gallstone, left inadvertently during LC, which developed an inflammatory phlegmon with abscess containing gallstone, causing extraluminal compression on the distal ileum, resulting in small bowel obstruction. This complication in particular is almost unheard of. The patient underwent laparoscopic drainage of abscess and retrieval of gallstone, which relieved the obstruction. Clinicians, therefore, need to keep an open mind in the workup for bowel obstruction. During LC, gallstone spillage should be prevented and retrieved whenever possible to minimize early and late complications associated with it.
