Gastroduodenal mucosal intussusception causing gastric outlet obstruction: a complication of gastrostomy tubes.

Acquired gastric outlet obstruction occurred in a neonate following gastrostomy, after surgery to salvage a dehisced primary repair of an esophageal atresia. Despite free drainage of the gastrostomy and total support of the neonate, the gastric outlet obstruction persisted and required a further operation. An anterograde gastric mucosal intussusception was found to be the cause.
