ENTEROLITH INTESTINAL-OBSTRUCTION OWING TO ACQUIRED AND CONGENITAL DIVERTICULOSIS - REPORT OF 2 CASES AND REVIEW OF THE LITERATURE

Diverticulosis of the small bowel, complicated by enterolith formation with ensuing obsturation obstruction, was recently documented in two patients. One patient had an enterolith formed within a Meckel's diverticulum; the other had an enterolith dislodged from an acquired diverticulum. Both patients presented with signs and symptoms of acute small bowel obstruction. Only 20 such cases of bowel obstruction secondary to jejunal enterolithiasis and five cases secondary to Meckel's enterolithiasis have been reported. The mechanism of obstruction may involve local encroachment or enterolith expulsion with distal bowel obstruction, although the latter is much more common. Optimally, enteroliths are broken up and milked into the proximal colon without incising the bowel. Alternatively, the enterolith may be milked proximally to a less edematous portion of bowel and an enterotomy may be performed. At times, the primary diverticulum is resected with the contained enterolith.
