The study of portal pressure during surgical exploration for biliary atresia in the series of 260 children operated at the Hospital Saint-Vincent de Paul since 1968 showed that portal hypertension could be demonstrated in 61.8% of the cases before the age of 3 months. Among the 54 children surviving without jaundice, splenomegaly was found in 35 cases; esophageal varices were seen in 14 children, more frequently after 5 years of age. Bleeding from esophageal varices occurred only in cases with recurrence of jaundice or moderate biliary retention, i.e. for 6 children. A portocaval shunt was constructed in 7 cases; all had bled except one. One child died two and a half years later from pneumococcal sepsis after a splenorenal shunt with splenectomy; another child had numerous recurrence of bleeding episodes. Five children have a functional shunt and have not rebled. When biliary atresia is cured by hepatoportoenterostomy, with complete disappearance of biliary retention, the risk of bleeding from esophageal varices is unlikely, in spite of persistent cirrhotic alterations of the liver; in these children, there should very seldom be an indication for a portocaval shunt.

Orthotopic liver transplantation (OLT) is a life-saving procedure for end-stage liver failure. We reviewed 39 children (24 girls, 15 boys) who received OLT for biliary atresia from 1987 to 1991. Twenty had unsuccessful portoenterostomy, 6 were referred too late for a drainage operation, and the remaining 13 achieved bile drainage but developed portal hypertension. At transplant 37 had decompensated liver disease with varices (28), ascites (24), encephalopathy (17), and gastrointestinal bleeding (12). The median weight and age at transplant were 8 kg and 12.6 months, respectively. The median waiting time was 65 days. Forty-eight grafts (30 reduced and 18 whole) were performed; graft loss was 33% and 27%, respectively. Of the 30 segmental grafts, 15 were reduced conserving the left lateral segment and hepatic vein (Brisbane technique)--13 were from the left lobe and 2 from the right lobe. The overall subject survival rate is 72%. Eleven deaths occurred: primary nonfunction (3), sepsis (3), perioperative bleed (3), and other causes (2). Early complications included: hepatic artery thrombosis (5), hepatic vein thrombosis (2), bowel perforation (3), biliary leak (3), and acute rejection (8). Later complications were chronic rejection (4) and biliary stricture requiring reconstruction (3). Follow-up at 12 months confirms good quality of life for both child and family with catch up growth and normal development. Technical advances in reduction hepatectomy have allowed us to treat small babies under 1 year with an urgent requirement for OLT, with comparable results to those obtained with whole grafts. In conclusion, in the future size and age need not be a contraindication to OLT in children with biliary atresia.

Therapy for patients with biliary atresia (BA) has become controversial, with orthotopic liver transplantation (OLTx) suggested in place of portoenterostomy. This is based on the unpredictable success of portoenterostomy, and the increased difficulty of the OLTx procedure following prior extensive liver surgery. The survival rate reported here for infants transplanted after unsuccessful portoenterostomy does not support this approach. OLTx was undertaken in 37 patients when end-stage liver failure followed primary portoenterostomy. Recipient age ranged from 6 months to 14 years (median, 13 months), and weight ranged from 5 to 45 kg (median, 8 kg) at the time of OLTx. Reduced-size allografts were used as the primary allograft in 25 patients (23 left lobe), and 12 received whole-organ allografts. Retransplantation was required in 5 patients, each received a reduced-size allograft. There was no increased incidence of vascular complications, primary nonfunction, irreversible rejection, intestinal perforation, biliary complications, sepsis, or lymphoma comparing the BA patients with all other non-BA patients who had undergone OLTx (all P = .16). There was no statistically significant difference in mean operative blood loss between BA patients (EBL = 1.99 BV) and non-BA patients (1.50 BV) (P = .14). Actuarial survival for the series of BA patients was 89% at 1 year, and 80% at 2 years. Following the introduction of reduced-size allografts, donor organs were selected for use with a priority on donor stability. The actuarial survival for BA patients during this time has improved to 96% at 1 year, and 91% at 2 years.(ABSTRACT TRUNCATED AT 250 WORDS)

Malnutrition is a critical predictor of mortality and morbidity in children with biliary atresia who undergo orthotopic liver transplantation. Growth hormone (GH) enhances nitrogen retention in patients with chronic obstructive lung disease, sepsis, and in fasted adult volunteers. The goal of this study was to assess the acute response to recombinant human GH (rhGH) treatment in children with biliary atresia to determine whether GH therapy was likely to improve pretransplant nutritional status. Five children, aged 10-32 months, with biliary atresia and persistent cholestasis despite surgical attempts to reestablish bile flow, were studied. All five children had portal hypertension, conjugated hyperbilirubinemia, and decreased serum albumin concentrations. Length, weight, and growth velocity were decreased in all five children. Despite adequate energy and protein intake, fat stores were depleted in all five subjects, and somatic protein stores were diminished in all except one child. Baseline serum concentrations of insulin-like growth factor-1 (IGF-1) and IGF-binding protein-3 (IGFBP-3) were low (8.4 +/- 2 ng/ml and 0.2 +/- 0.1 mg/l respectively). In the four children who completed the study, serum IGF-I and IGFBP-3 levels did not change after treatment with rhGH (0.1 mg/kg/day) for 4 days. Our findings indicate that children with biliary atresia awaiting liver transplantation are insensitive to GH and that treatment with GH is unlikely to promote anabolism. A rationale exists for examining the effect of treatment with IGF-I, which mediates the anabolic effects of GH.

Technetium Tc-99m disofenin cholescintigraphy (CS) and ultrasonography (US) are two major clinical methods used in differentiating biliary atresia (BA) from neonatal jaundice. To compare the diagnostic utility of these two modalities, 66 patients with neonatal cholestasis (15 BA, 3 choledochal cyst (CC), 32 neonatal hepatitis, 13 prolonged jaundice, 2 total parenteral nutrition, and 1 sepsis) underwent Tc-99m disofenin CS and US. The diagnostic sensitivity, specificity, and accuracy of CS in differentiating BA from other forms of neonatal jaundice was 100%, 87.5%, and 90.5%, respectively, and for US 86.7%, 77.1%, and 79.4%, respectively. Tc-99m disofenin CS after premedication with phenobarbital and cholestyramine is a convenient and reliable method of differentiating BA from neonatal hepatitis, with a diagnostic accuracy superior to that of US. However, US is the initial imaging procedure of choice in patients presenting with jaundice to rule out anatomic anomalies such as CC.

Nine pediatric patients (mean age, 10 years) with biliary atresia, who had hypoxemia related to intrapulmonary shunting, underwent living related liver transplantation. The effects of hypoxemia during the early postoperative period after liver transplantation on cardiopulmonary and renal function, as well as on transplanted liver, were analyzed. Based on the degree of shunt ratio calculated by technetium-99m macroaggregated albumin scintigraphy, the nine patients were included in the moderate group (shunt ratio under 40%, n=4) or the severe group (shunt ratio over 40%, n=5). Partial pressure of arterial oxygen was maintained at normal range in the moderate group, while that in the severe group persistently had very low values (<50 mmHg), in spite of a high degree of oxygen supply. However, all patients in the severe group maintained stable cardiopulmonary vital signs, including systemic blood pressure, heart rate, respiratory rate, and cardiac index. They also demonstrated stable renal function. None of the patients died of cardiopulmonary or renal insufficiency after transplantation, but three patients died of portal vein thrombosis, sepsis, and intracranial hemorrhage (one each). The minimal adverse effect of hypoxemia on the transplanted liver was confirmed by a rapid increase of arterial ketone body ratio, low peak values (under 200 IU/L) of aspartate aminotransferase, and a steady decrease of serum total bilirubin. Four patients encountered surgical complications, including two bile leaks from the cut liver surface, two leaks from bilioenteric anastomosis, and one intestinal perforation. Six patients suffered from bacterial infections, including four wound infections, three right subphrenic abscesses, one cholangitis, and two systemic sepses. All patients in the moderate group recovered from hypoxemia, but four of five patients in the severe group have not recovered during the follow-up period between 4 and 9 months. It was concluded that the adverse effects of hypoxemia on cardiopulmonary and renal function and transplanted liver were minimal, so that patients with severe hypoxemia could tolerate the stress of liver transplantation without special management. However, the high incidence of surgical complication and infection suggested the adverse effects of hypoxemia on wound healing and resistance to bacteria infection.

Eleven children, 4 males and 7 females, with biliary atresia receiving living related liver graft were studied. The mean age was 1.8 years and the mean body weight was 10.3 kg. The donors were 4 fathers and 7 mothers. The graft was the lateral segment or left lobe. ABO blood group matching was compatible in 9 and incompatible in 2. All patients except one were crossmatch negative. Immunosuppression at induction was triple therapy (cyclosporine, azathioprine and steroid) or FK506 plus steroid. Acute rejection episodes were treated with pulse steroids. When the signs of rejection persisted despite steroid pulse therapy, 15-deoxyspergualin (DSG) was added. The survival rate of the patients was 73%. Three patients died of portal vein thrombosis, hepatic artery thrombosis and sepsis respectively. Other major complications included hyperbilirubinemia, bile duct stenosis, bile leakage and portal vein anastomosis narrowing. Complications of the donor were sepsis in one, and liver dysfunction in two. Although there are some complications related to graft size mismatch and operative procedure, living related partial liver transplantation is an effective therapy in countries where donor source is restricted.

The diagnosis of acute rejection in liver transplantation usually needs hepatic biopsy, but hepatic biopsy sometimes involves severe complications. We analyzed biliary bilirubin fraction after living related liver transplantation by using high performance liquid chromatography (HPLC) and investigated availability for the early diagnosis of acute rejection retrospectively. Nine children with liver cirrhosis due to biliary atresia were included in this study, who underwent living related liver transplantation at The Second Department of Surgery, Tohoku University School of Medicine. Bile was collected daily from a biliary canulae inserted into the hepatic duct of the graft under aseptic and without exposure to the light. We measured the proportion of bilirubin diglucuronide (BDG), bilirubin monoglucuronide (BMG) and unconjugated bilirubin (UCB) of bile pigments in the bile by HPLC. In three of four patients with acute rejection, BDG + BMG (= Bc) was above 85% and BDG/Bc ratio was below 0.6 at the time of hepatic biopsy. After rejection therapy, BDG/Bc ratio increased in their bile. The remaining one case with acute rejection as well as bile duct injury due to arterial thrombosis of S2, Bc was below 85%, and BDG/Bc ratio was below 0.6. In four of the other five patients who had several severe complications, i.e., arterial or portal vein thrombosis, bile stasis due to cholangitis and sepsis due to necrotizing myofascitis, Bc was below 85% and BDG/Bc ratio was below 0.6. We concluded that analysis of biliary bilirubin fraction after liver transplantation could be reliable as a noninvasive maker and valuable for the early diagnosis of acute rejection.

The presence of jaundice in the neonate, infant or young child presents a broad differential diagnosis. The 'disease' may be benign, as in breast-milk jaundice, or potentially fatal, as in hereditary fructose intolerance. The cause of the jaundice may be a primary hepatic disorder, such as extrahepatic biliary atresia, or secondary to a non-hepatic cause, such as haemolysis or sepsis. There may be significant hepatic injury and dysfunction, as in fulminant viral hepatitis, or simply elevation of plasma bilirubin, as in Gilbert's syndrome. In this chapter we will discuss the familial hyperbilirubinaemia syndromes. This diverse group of disorders is characterized by hepatic dysfunction in the absence of hepatocellular injury. The first section of the chapter will discuss the unconjugated hyperbilirubinaemias: Crigler-Najjar syndrome I, Crigler-Najjar syndrome II and Gilbert's syndrome. The discovery of the gene for bilirubin uridine diphosphate glucuronosyltransferase has increased our understanding of the genetic heterogeneity and clinical presentation of the Crigler-Najjar syndromes. The remainder of the chapter will discuss the conjugated hyper-bilirubinemias: Rotor syndrome and Dubin-Johnson syndrome. These rare diseases share many clinical features; however, they can be readily distinguished by biochemical markers in the urine and bile.

A hepatic portocholecystostomy (HPC) has been recommended to avoid postoperative cholangitis in the case of a patent distal extrahepatic bile duct (PDEBD) for the treatment of biliary atresia (BA). We investigated the efficacy and clinical problems of HPC in BA. The clinical records of eight patients with BA and PDEBD were reviewed. The diameter of the common bile duct was compared between the patients with BA and PDEBD and age-matched patients with neonatal hepatitis (NH). Five of 8 patients with PDEBD underwent HPC. One patient had to be converted to a cholecystojejunostomy because of common bile duct stenosis at 19 years of age. The other two patients underwent a reoperation by a hepatic portojejunostomy due to poor bile drainage after HPC. Another patient became jaundice-free one month after HPC, but died of sepsis due to bile leakage 3 months thereafter. The mean diameter of the common bile duct in BA with PDEBD was significantly smaller than that of NH (0.76 +/- 0.16 mm (n = 8) in BA vs. 1.90 +/- 0.39 mm (n = 11) in NH, p<0.01). HPC was thus found to be an excellent operative method for preventing postoperative cholangitis in BA, however, many clinical problems still need to be overcome for such a narrow distal duct.
