Intestinal obstruction secondary to a colonic lithobezoar.

A bezoar is an accumulation of indigestible exogenous matter in the stomach and intestine. A myriad of ingested substances have been found impacted in the digestive tract. Bezoars are uncommon causes of intestinal obtruction during childhood. Lithobezoar, an accumulation of ingested stones within the alimentary tract, is an extremely rare clinical entity. We report one such case in a 9-year-old boy with a history of pica and long-term constipation resulting in intestinal obstruction secondary to a colonic lithobezoar. Only two such cases have been reported previously.
