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.

[Liver transplantation in the child. The situation in Europe and personal results of the first 100 patients].

Pediatric liver transplantation in Europe has expanded rapidly during the last four years. The survival rate of the 254 children less than 15 years recorded in the European Registry on December 31, 1987 was 68% at one year and 61% at three years; nineteen centers have contributed to this activity, of which 11 had performed less than 5 cases each while two thirds of the experience was concentrated in three centers (Brussels, Cambridge, Hannover). The results obtained in the first 100 children (65% were younger than 3 years) who received a liver graft at the University of Louvain Medical Center in Brussels between March 1, 1984 and July 31, 1988 are reported. The survival rates (79% at one year and 73% at three year) which do not differ with regard to the age, the indication of the technical modalities (whole liver or reduced size livers) are strongly influenced by the clinical condition (84% vs 50% at one year in elective and emergency transplantations respectively). One third of the 122 grafts transplanted by the authors were reduced livers harvested from older and often adult donors. This technique provides results of equal quality and does not entail an increased rate of technical complications; on the contrary, the incidence of arterial thrombosis has been significantly reduced. Transplantation of a reduced size liver is safe and should be recommended even in elective conditions, in view of the dire shortage of small pediatric donors.

[Indications for liver transplantation in Wilson's disease].

We report the case of a 12 year-old boy with Wilson's disease, presenting with decompensated liver cirrhosis. Medical treatment failed to prevent fulminant liver failure in less than one month. Emergency liver transplantation was successfully performed. This report led us to review the prognosis of Wilson's disease with liver failure according to the present results of liver transplantation.

Hepatic transplantation in Europe. First Report of the European Liver Transplant Registry.

At the 32 European centres where livers are transplanted the actuarial survival rate for 1218 patients was 44% at 1 year and 41% at 2 years. Perioperative mortality (30 days) was 30%. Recipients aged under 15 years had a higher survival rate than those aged over 15; the differences were 22% at 1 year and 32% at 2 years. For the 97 patients who received two or more liver grafts, actuarial survival was 27.7% at 1 and 2 years. Two-thirds of the transplantations were done since 1984. Since then the best results have been obtained for biliary atresia (88 cases; survival rates at 30 days, 1 year, and 2 years were 87%, 74%, and 68%). Primary biliary cirrhosis was the commonest benign indication for transplantation, with survival of 64% at 1 and 2 years. The proportion of transplantations that were done for patients with hepatocellular carcinoma was smaller after than before 1984; among transplantations done in adults after 1984, those done because of hepatocellular carcinoma gave the best perioperative survival rate (76%) but the worst 2 year survival (30.8%).

Double-blind controlled study on the efficacy of sodium alginate (Gaviscon) in reducing gastroesophageal reflux assessed by 24 h continuous pH monitoring in infants and children.

We studied the effects of an alginate compound (Gaviscon) on the frequency and the duration of gastroesophageal reflux (GOR) episodes in children. Twenty infants and children with characteristic symptoms of GOR were divided at random into two groups which were given either Gaviscon (ten patients, mean age: 21 months) or a placebo (ten patients, mean age: 35 months). A continuous pH probe monitoring of the lower oesophageal third was performed in all the patients before and after 8 days of treatment. Before the trial, sensitive pH monitoring variables of acid reflux (Euler-Byrne index, percentage of total reflux time per 24 h, mean duration and percentage of reflux time during sleep, total number of reflux episodes per 24 h and number of reflux episodes per 2 h post-cibal periods) were abnormal in all the patients tested. The oesophagram revealed a GOR in 13 of the 20 patients; none of the children who underwent an endoscopy had evidence of oesophagitis. Episodes of regurgitation reported by the parents decreased during Gaviscon therapy while no clinical improvement was noticed in the placebo group. No adverse effects were observed. After 8 days of treatment with Gaviscon, results of all the pH monitoring variables were significantly (P less than 0.05) reduced between -35% and -61% of the initial values recorded. In the placebo treated group, the mean values remained little changes (-9.5 to +8.2% of initial values). These data suggest that Gaviscon may prove useful in the medical management of GOR in infants and children.
