Luminal narrowing after autoanastomosis and intraluminal slough in intussusception: a case report and historical review.

Historical literature notes slough of an intussusceptum with autoanastomosis as an infrequent natural course of childhood intussusception resulting in survival. The case of an 8-year-old boy with abdominal pain several years after an apparent untreated childhood intussusception is presented. Cecal resection shows evidence of previously sloughed intussusceptum with cicatral luminal narrowing at site of autoanastomosis. This case illustrates a rare cause of abdominal pain and partial intestinal obstruction in childhood.
