Hepatic artery thrombosis in pediatric liver transplantation.

The incidence of hepatic artery thrombosis was analyzed in a series of 59 consecutive liver transplants performed in 52 children less than 15 years of age at the University of Louvain Medical School, Brussels, from March 1984 to March 1987. This incidence was 17% for the whole series; it was increased in small recipients less than 3 years of age and less than 15 kg (23%) in weight, as well as when the liver was harvested from a small donor less than 15 kg in weight (38%). It was also increased when the donor liver was supplied by more than one artery. This incidence was markedly reduced by arterial revascularization from the aorta, either directly or by interposition of an iliac segment; the reduced-size livers had a much lower incidence of arterial thrombosis (5%) than the whole livers (23%). In the present series, we did not find any argument to support the view that poorly controlled rejection could be implicated in the pathogenesis of arterial thrombosis

Pediatric liver transplantation: report on 52 patients with a 2-year survival of 86%.

Between March 1984 and March 1987, 59 orthotopic liver transplantations have been performed in 52 children at the Catholic University of Louvain in Brussels. The actuarial survival was 86% +/- 5 up to 3 years of evolution. The most frequent indication has been chronic hepatic insufficiency (43 patients) mainly because of biliary atresia; seven patients were transplanted for acute hepatic insufficiency and only two for liver tumor. Because of important donor/recipient weight discrepancy, a reduced-size liver was used in 20 occasions either for first or second transplant. No difference in the incidence of major complications were seen between whole liver and reduced size liver transplanted children, with the exception of more frequent subhepatic collections in the first and more hepatic artery thrombosis in the second group. Liver tests, clinical rehabilitation, and survival appear to be equal in the two groups

Liver transplantation for biliary atresia: indications and results.

This report reviews the results of some paediatric surgical departments and points out the unsolved problems in biliary atresia disease. The authors conclude that a 5-year survival rate of 60% may be achieved in long-term follow-up, but a complete cure is observed only in 30%. Children who develop a cirrhosis and portal hypertension without or in spite of bile flow can benefit only by liver transplantation. As a result of long-term clinical experience conditions are defined that should be taken in consideration in the surgical treatment of bile duct atresia. In respect of liver transplantation the disadvantages of an external bile draining fistula to prevent cholangitis, an extensive mobilisation of the liver for HPE procedure, and the disadvantages of reoperation are discussed. By avoiding these disadvantages liver transplantation procedure will be facilitated and a 1-2 year survival rate of 80% may be achieved

Outcome of Exfoliative Rejection After Isolated Intestinal Transplantation in an Adult: Case Report

A 34-year-old-man with short-bowel syndrome received an isolated small bowel graft. On postoperative day (POD) 11, ileal biopsy specimen demonstrated mild to moderate rejection that did not respond to corticosteroid bolus therapy. On POD 14, endoscopy and histologic examination revealed exfoliative rejection that was not controlled after 14 days of therapy with thymoglobulin. On POD 95, the patient underwent surgery again because of intestinal obstruction. The graft was removed 6 months after transplantation because of continuous severe abdominal pain with weight loss. After enterectomy, the patient developed multiple-organ failure and died on POD day 8. This case underlines the severity of exfoliative rejection and suggests that early enterectomy be performed when the diagnosis is made, before deterioration of clinical status and development of infectious and nutritional complications
