Specimens of excised tissue from the porta hepatis in 26 infants with extrahepatic biliary atresia undergoing hepatic portoenterostomy were analysed histologically for the presence and size of biliary ductules. No correlation could be found between the establishment of effective biliary drainage and the number or size of biliary ductules. it is suggested that prognosis after surgery may be related to the intrahepatic lesion and age of the child at operation rather than to the histology of the extrahepatic bile duct remnants. 相似文献

Purpose
Total bilirubin (T-bil) is used universally for monitoring post-portoenterostomy (PE) biliary atresia (BA) patients although other biochemical markers [BM; AST/ALT and platelet count (PC)] are also prognostic. We compared open PE (OPE) with laparoscopic PE (LPE) using T-bil, AST/ALT, and PC (3BM) as more comprehensive indicators of postoperative clinical status.Methods
Subjects were 31 PE cases (LPE: n = 17; OPE: n = 14). BA classification was type III (n = 16), type II (n = 1) in LPE and type III (n = 12), type I (n = 1), type II (n = 1) in OPE.Results
Mean ages and weights at PE were similar: 65.5 days, 4.4 kg (LPE) versus 69.3 days, 4.1 kg (OPE); and mean follow-up was 2.5 years for both LPE and OPE. Jaundice clearance (T-bil ≤1.2 mg/dL) was achieved in 16/17 (94.1 %) after LPE versus 10/14 (71.4 %) after OPE (p = NS), but 3BM were closer to normal after OPE. At the time of review, 13/17 LPE cases (76.5 %) were alive with native livers and 4/17 had received LTx (23.5 %) and 10/14 OPE cases (71.4 %) were alive with native livers and 4/14 had received LTx (28.6 %).Conclusions
Although JC was better after LPE, 3BM were better after OPE. Further follow-up will prove the comprehensive prognostic value of 3BM.3.

Hepatic calcification was found in an anicteric infant with biliary atresia after hepatic portoenterostomy. When she was 2 years of age, ultrasonography detected an echogenic structure with acoustic shadowing. Computerized tomography located it at the proximal portion of Segment 6 in the right lobe. Although both techniques failed to exhibit dilatation of the peripheral bile ducts, we believe intrahepatic cholelithiasis provides the most likely diagnosis. Although seven cases with biliary atresia were reported to have this complication, all of them were icteric when the diagnosis was confirmed. The patient should be carefully followed up since the succeeding stones may cause jaundice by obstructing the main duct. 相似文献

Conventional surgery for extrahepatic bile-duct atresia (EHBDA) usually requires a large, painful, muscle-cutting laparotomy, dislodgment of the liver, and wide manipulations, followed by adhesions and possible complications that may disturb the postoperative course and hamper liver transplantation (LT). The main role of laparoscopy in EHBDA has been for diagnostic purposes. Besides all the advantages of minimally-invasive access, it allows excellent visibility and dissection of tiny hilar structures. The authors present the first two cases of successful Roux-en-Y laparoscopic portoenterostomy (LARP) for EHBDA, showing the importance of advanced technical skills and a new approach for extracorporeal enteroanastomosis. Laparoscopic hilar dissection and portoenterostomy was accomplished using four trocars. The umbilical site was used for extracorporeal Roux-en-Y enteroenterostomy, in the first case using a laparoscopic stapler and in the second a hand-sewn suture. Mean operative time was 190 min, and no operative complications were observed. Both girls became anicteric. The first is doing well 15 months after the operation with good hepatic function. The other was anicteric for 6 months, had one episode of cholangitis, developed an umbilical hernia, has shown slow and progressive hepatic failure, and is now being evaluated for possible LT. It is concluded that LARP for EHBDA can be done safely in infants using an extracorporeal transumbilical enteric anastomosis, with several advantages compared with open surgery. The role of LARP in facilitating LT is yet to be defined. 相似文献

BACKGROUND: The outcome of the hepatic portoenterostomy (Kasai) procedure for biliary atresia is improved when it is performed before 90 days of age. However, it is not known whether intervention before 30 days is better than intervention between 30 and 90 days. METHODS: The authors reviewed the records of all patients seen by the Pediatric Gastroenterology Service at St. Louis Children's Hospital from 1984-1999 to ascertain the outcome of patients who underwent Kasai procedure before or after 30 days of age. RESULTS: Of 92 patients with biliary atresia treated at St. Louis Children's Hospital over 15 years, 9 underwent the Kasai procedure before 30 days of age. Liver transplantation was necessary in 77.8% of these patients at a mean age of 11.0 +/- 4.26 months, as compared with 53.4% at 32.14 +/- 7.14 months for the remainder of the patients who underwent the procedure after 30 days of age. CONCLUSIONS: Although these data suggest that outcomes are worse for patients who undergo the procedure before 30 days of age, they may reflect a difference in the pathogenesis of biliary atresia that brings it to clinical attention earlier and may provide further evidence that biliary atresia is a phenotype for a number of distinct underlying disease processes. 相似文献

We report our experience with 4 cases of cystic dilatation of intrahepatic bile ducts following hepatic portoenterostomy for
biliary atresia. Two of the cases did not achieve satisfactory bile excretion and all four cases developed recurrent cholangitis
after hepatic portoenterostomy. The attacks of cholangitis seemed to be associated with the presence of intrahepatic cysts.
Although one case resulted in death from hepatic failure, three other cases are now outpatients. Patients who develop recurrent
cholangitis following hepatic portoenterostomy, should be examined to exclude the presence of intrahepatic biliary cysts.
Ultrasonography, computed tomography and percutaneous transhepatic cholangiography were all effective in detecting cysts and
provided valuable information for planning treatment. Percutaneous transhepatic or surgical drainage of the bile ducts was
effective in reducing jaundice, and recurrent cholangitis. 相似文献

Bile lakes develop after hepatic portoenterostomy in some patients with biliary atresia, and have been regarded as an indication
of poor prognosis. We reported that bile lakes have no epithelium of the bile duct on their wall, and are surrounded by bile
ducts; however, the mechanism of bile lake formation is little known. We investigated histologically how bile ducts are formed
using whole removed liver, and the characteristics of bile ducts around bile lakes. From April 1980 to July 2006, we encountered
84 patients with biliary atresia. Bile lakes were analyzed histologically in 11 patients who underwent liver transplantation
in our hospital. Bile lakes had a fibrotic cyst wall and lacked epithelia. In most cases, bile stasis, calculi formation,
damaged bile ducts, and invasion of inflammatory cells were observed around the bile lakes. Bile ducts around bile lakes were
not stained by CD56, but bile ducts around liver lobuli were stained by CD56. The present study speculates that bile lakes
would arise from original bile ducts, which are damaged, and fuse together after calculi are formed in bile ducts. 相似文献

A retrospective analysis was performed of the records of 133 patients with extrahepatic biliary atresia (EHBA) who had undergone a Kasai portoenterostomy. The patients were divided into a non-transplantation group who survived but did not receive liver transplantation after the procedure and a failure group of those who died or received liver transplantation. A score was calculated that assessed nine factors, including laboratory values and complications. The data were assessed at the time complications occurred. The scores were analysed by a trend analysis to see if serial scores predicted the evolution of liver disease. A receiver operating characteristic (ROC) curve was plotted to assess the optimal cut-point for the scoring system. There were 98 patients in the non-transplantation group and 35 in the failure group. The latter group had significantly higher post-operative bilirubin (9.3±7.2 mg/dl versus 3.5±3.1 mg/dl), ALT (136±89 U/l versus 92±88 U/l), prothrombin time, and incidence of cirrhosis, ascites, oesophageal varices, portal hypertension, cholangitis and sepsis than the non-transplantation group ( P <0.05). A score of 8 had a high sensitivity (96.9%) and specificity (89.5%) for predicting the need for liver transplant. Conclusion:based on easily available clinical information, our scoring system can predict which patients with biliary atresia who have already undergone a Kasai procedure should be considered for liver transplantation.Abbreviations EHBA extrahepatic biliary atresia - ROC receiver operating characteristic 相似文献

Portal vein (PV) shrinkage sometimes eliminates the possibility of liver transplantation in biliary atresia patients after hepatic portoenterostomy. To determine the factors leading to PV shrinkage, we performed a serial sonographic study of the portal venous system in 21 children. Cross-sectional PV area and mean portal venous velocity (PVV) were reduced in patients with refractory cholangitis and those with gastroesophageal varices and cholangitis. Although the reduction in cross-sectional PV area was greater in patients with four-time laparotomy than single laparotomy, the mean PVV was not reduced by repeated laparotomy. Patients with varices were lower in age, weight, mean PVV, cross-sectional PV area for age, and had higher serum total bilirubin levels. In conclusion, refractory cholangitis is a significant factor in shrinking the PV. With active bile drainage, varices spontaneously regress, the PV increases in both caliber and total length per unit hepatic volume, and PVV normalizes. It is suggested that pulsed Doppler PV sonography can help to determine the optimal time for liver transplantation referral in biliary atresia patients with progressive cirrhosis.This work was supported by a Grant for Pediatric Research (63-A-05) from the Ministry of Health and Welfare.
