Case Report- Meckel's diverticulum lithiasis: A case of small bowel obstruction due to a migrated Meckel's Enterolith

We report a case of small bowel obstruction due to a stone formatted within a Meckel′s diverticulum, expelled into the lumen and impacted prior to the ileocecal valve. Only a small number of ileus due to Meckel′s diverticulum lithiasis has been described in the literature. Meckel′s diverticulum as congenital out-pouchings of the small bowel can be liable to bleeding, perforation, obstruction and rarely to enterolith formation. Extrusion of the stone from the diverticulum can lead to acute small bowel obstruction. In patients presenting with acute mechanical small bowel obstruction without an obvious cause, Meckel′s lithiasis should be included in the differential diagnosis.
