Abstract The aim of this study was to assess the risk and prognostic factors of gut perforation after orthotopic liver transplantation in children with biliary atresia using univariate and stepwise regression analysis. Among 51 pediatric recipients who underwent transplantation because of biliary atresia after failure of portoenterostomy, 10 patients (20%) had 19 episodes of gut perforations after 14 transplantations. The median delay between transplantation and perforation was 13 days. These perforations were treated either by suture (n = 21) or ostomy (n = 11). The study of preoperative and perioperative variables showed that children with gut perforation were in surgery for a significantly longer period of time including a longer period of receiving hepatectomy and undergoing portal venous clamp. These children also needed large amounts of blood transfused during hepatectomy. After transplantation there was no difference regarding total steroid doses and early occurrence of cytomegalovirus disease between the two groups. Stepwise regression analysis identified three factors associated with the occurrence of gut perforation: duration of transplant operation, posttransplant intra‐abdominal bleeding requiring reoperation, and early portal vein thrombosis. During the postoperative course, severe fungal infections were significantly more frequent in the gut perforation group. The 3‐year patient survival rate was 70% in the group with gut perforation and was not different from the group without perforation (80%). This study shows that children with previous portoenterostomy carry a high risk of developing gut perforation after liver transplantation. This is especially true for those patients with the most difficult hepatectomies, which are responsible for the iatrogenic injury of the bowel. Other risk factors pointed out in this study were splanchnic congestion in case of prolonged portal venous clamp time or early portal vein thrombosis and repeated trauma of the bowel caused by reoperations. On the other hand, other well known risk factors, such as steroid therapy and viral diseases, were not involved in the occurrence of gut perforations in this study. Besides emergent surgical treatment, this type of complication requires aggressive therapy against fungal infections. Copyright © 1995 by the American Association for the Study of Liver Diseases.
