Bladder wall necrosis in an extremely low-birth-weight infant: a thought-provoking complication of necrotizing enterocolitis.

An 879-g baby boy had catastrophic necrotizing enterocolitis (NEC) at 29 days of life and underwent surgical laparotomy with a subsequent ileostomy and peritoneal drain placement. The infant was subsequently stable until 42 days of life when a spontaneous perforation of the bladder apex was diagnosed by a suprapubic cystogram. Laparotomy on day of life 46 found a loop of dead bowel herniating into a necrotic hole of the bladder dome. This case shows a previously unreported complication of NEC and discusses the possibility that prolonged use of a peritoneal drain may have permitted its genesis.
