Mesodiverticular Band with Meckel’s Enterolith Caused Acute Small Bowel Obstruction and Perforation: A Case Report and Review of Literature

The most common congenital anomaly of the gastrointestinal tract is the Meckel’s diverticulum which is a true diverticulum, involving the whole walls of the small intestine. John Friedrich Meckel described the embryological basis for congenital diverticulum of the midgut in 1809. Meckel’s diverticulum is complicated with enterolithiasis in 3 - 10% of cases. Adults with Meckel’s diverticulum are most likely to present with intestinal obstruction. Meckel’s primary enterolith and Meckel’s mesodiverticular band rarely cause acute small bowel obstruction. However, we did a thorough literature search, and we were unable to find a single case where both Meckel’s primary enterolith and Meckel’s mesodiverticular band were causing acute small bowel obstruction and perforation. We report such a case, and ours is the first of its type.
