Small-bowel obstruction associated with Crohn's enterolith.

One of the lesser known clinical manifestations of Crohn's disease is the formation of small-bowel enteroliths. These concretions precipitate in the setting of small-bowel stasis within the alimentary tract and are associated with a variety of disease states causing strictures or diverticula. In the acute setting, patients typically present with signs of intestinal obstruction due to stone impaction. The case we report involves a 67-year-old female with long-standing Crohn's disease who presented with a 6-day history of worsening abdominal pain. Plain abdominal radiographs demonstrated dilated bowel loops consistent with intestinal obstruction. Computed tomography revealed a 2.5-cm calcified density at the transition point in the distal ileum, and two additional stones were present in the proximal ileum. At surgery, multiple ileal strictures were found, and ileocolic resection with primary anastomoses was performed. The accurate diagnosis of enterolithiasis in the setting of Crohn's disease has significant clinical implications for management and is a harbinger of underlying bowel stenosis.
