Bowel perforation after paediatric orthotopic liver transplantation.

Bowel perforation is a well-recognized complication following orthotopic liver transplantation. Of 194 paediatric liver transplantations performed in our hospital, 13 patients (6.7%) developed bowel perforation post-transplantation. Contributory factors included previous operation, steroid therapy and viral infection. The incidence was higher in children who underwent transplantation for biliary atresia after a previous Kasai portoenterostomy. Seven patients (53% of this group) reperforated. Diagnosis may be difficult and a high index of suspicion is needed.
