Abstract
Biliary atresia is an occlusive biliary disease involving intrahepatic and extrahepatic bile ducts. Its etiology and pathogenesis are unclear. There are many manifestations of bile duct involvement in biliary atresia, but little is known about its occurrence and development. In addition, different classification methods have been proposed in different periods of biliary atresia, each with its advantages and disadvantages. The combined application of biliary atresia classification will help to improve the survival rate of patients with native liver. Therefore, this article reviews the development, pathological features, and classification of intrahepatic and extrahepatic bile ducts in biliary atresia, to provide a reference for the study of the pathogenesis and the choice of treatment methods.

Abstract
Exposure to plant toxins or microbiota that are able to digest common food ingredients to toxic structures might be responsible for biliary atresia (BA). An isoflavonoid, biliatresone is known to effectively alter the extrahepatic bile duct (EHBD) development in BALB/c mice. Biliatresone causes a reduction of Glutathione (GSH) levels, SOX17 downregulation and is effectively countered with N-Acetyl-L-cysteine treatment in vitro. Therefore, reversing GSH-loss appears to be a promising treatment target for a translational approach. Since BALB/c mice have been described as sensitive in various models, we evaluated the toxic effect of biliatresone in robust C57BL/6J mice and confirmed its toxicity. Comparison between BALB/c and C57BL/6J mice revealed similarity in the toxic model. Affected neonates exhibited clinical symptoms of BA, such as jaundice, ascites, clay-colored stools, yellow urine and impaired weight gain. The gallbladders of jaundiced neonates were hydropic and EHBD were twisted and enlarged. Serum and histological analysis proved cholestasis. No anomalies were seen in the liver and EHBD of control animals. With our study we join a chain of evidence confirming that biliatresone is an effective agent for cross-lineage targeted alteration of the EHBD system.

Abstract
OBJECTIVE To explore the diagnostic performance of prenatal ultrasound in the prediction of biliary atresia (BA). METHODS We prospectively collected cases of suspected biliary abnormalities in the 2nd trimester of pregnancy and performed a series (at least 3) of prenatal ultrasound examinations in the 2nd and 3rd trimester. The presence of the gallbladder was examined each time, and its size and shape were assessed if the gallbladder was visible. The existence of other abnormalities was carefully evaluated. Neonatal ultrasound examination was conducted within 1 month after birth, and clinical data were followed-up for 6 months after birth. RESULTS Among the 41 895 patients, 298 were suspected to have biliary abnormalities, while 82 patients were excluded due to loss to follow-up or induced labor caused by other abnormalities. A total of 216 patients were included in this study, and 15 were diagnosed with BA. We summarized the ultrasound findings of the gallbladders and defined a high-risk gallbladder for the prenatal diagnosis of BA. This was demonstrated to have the best diagnostic performance as a single parameter, with an area under the curve of 0.914 (95 %CI: 0.869-0.948). In addition, higher incidences of biliary cysts, right hepatic artery dilation, echogenic bowel, and ascites were observed in BA fetuses. Logistic regression analysis showed that the combination of 5 parameters had better diagnostic performance, with an area under the curve of 0.995 (95 %CI: 0.973-0.999). CONCLUSION The fetal gallbladder was found to be a critical feature for the identification of BA. Concomitant abnormalities could be helpful to improve the accuracy of the diagnosis.

Abstract
Hereditary cholestatic liver disease caused by a class of autosomal gene mutations results in jaundice, which involves the abnormality of the synthesis, secretion, and other disorders of bile acids metabolism. Due to the existence of a variety of gene mutations, the clinical manifestations of children are also diverse. There is no unified standard for diagnosis and single detection method, which seriously hinders the development of clinical treatment. Therefore, the mutated genes of hereditary intrahepatic cholestasis were systematically described in this review.

Abstract
OBJECTIVE The objectives of this study is to compare the prognostic differences between cystic biliary atresia (CBA) and non-CBA, analyze the clinical and liver pathological differences between the two groups, and explore the possible factors that affect the native liver survival of infants with CBA after Kasai portoenterostomy (KPE). METHODS From 2013 to 2020, 131 infants with BA were admitted to Tianjin Children's Hospital. A total of 108 infants with BA were included after excluding those who did not undergo surgery after diagnosis (n = 23), including 12 cases of CBA and 96 cases of non-CBA. The clinical data, native liver survival and liver pathology, including liver fibrosis, bile ductular proliferation (BDP), bile plug, and portal area inflammation infiltration of the two study groups were compared. RESULTS CBA accounts for 9.16% (12/131) and type I CBA accounts for 6.87% (9/131) of all types of BA. 16.7% (2/12) of CBA were detected prenatally with diagnosis of choledochal cyst (CC). The age at KPE, total bilirubin, direct bilirubin, and total bile acid levels of CBA were significantly lower than those of non-CBA (P = 0.047, P = 0.013, P = 0.009, P = 0.010, respectively). The long and wide diameters of the gallbladder were significantly larger than those of non-CBA (both P < 0.001). The 1-, 3-, and 5-year survival rates of CBA were 83.3%, 71.4%, and 71.4%, respectively, and 56.5%, 32.5%, and 29.8%, respectively, in non-CBA. The difference between the two groups was statistically significant (P = 0.031). The degree of liver fibrosis and bile plug in non-CBA was higher than that of CBA (P = 0.004, P < 0.001, respectively). There was no difference of BDP and inflammation infiltration between the two groups (P = 0.285, P = 0.243, respectively). CONCLUSION CBA is a distinct type different from non-CBA, with different pathological processes, pathological manifestations, and clinical prognosis. The favorable prognosis of CBA may be derived from the early diagnosis, early operation, and mild pathological changes.

Abstract
The liver emerges from the ventral foregut endoderm around 3 weeks in human and 1 week in mice after fertilization. The fetal liver works as a hematopoietic organ and then develops functions required for performing various metabolic reactions in late fetal and neonatal periods. In parallel with functional differentiation, the liver establishes three dimensional tissue structures. In particular, establishment of the bile excretion system consisting of bile canaliculi of hepatocytes and bile ducts of cholangiocytes is critical to maintain healthy tissue status. This is because hepatocytes produce bile as they functionally mature, and if allowed to remain within the liver tissue can lead to cytotoxicity. In this review, we focus on epithelial tissue morphogenesis in the perinatal period and cholestatic liver diseases caused by abnormal development of the biliary system.

Abstract
Purpose This study explored the performance of prenatal ultrasonography in the differential diagnosis of cystic biliary atresia (CBA) and choledochal cyst (CC). Methods Fetuses diagnosed with hepatic hilar cyst in the second trimester were included in this study. A series of prenatal ultrasound examinations were performed in the second and third trimesters. The diameter of the gallbladder (GB) and hepatic cyst were measured, as well as the wall thickness of the GB. The GB-cyst connection, visibility of the right hepatic artery (RHA), and other concomitant abnormalities were carefully evaluated. A neonatal transabdominal ultrasound examination was performed within 1 week after birth, and clinical data were followed up to 6 months after birth. Results Between January 1, 2016 and January 31, 2020, 53 fetuses diagnosed with hepatic hilar cyst were recruited. Eight were excluded because they were lost to follow-up. Among the 45 cases included in this study, 10 were diagnosed with CBA and 35 with CC after birth. Statistically significant differences were found in GB width, wall thickness, change in GB width, change in cyst length, GB-cyst connection, and RHA visibility between the CBA and CC groups. GB width showed the best diagnostic performance with an area under the curve (AUC) of 0.899. The combination of GB width, GB wall thickness, and GB-cyst connection yielded a comparable AUC of 0.971. Conclusion The GB should be carefully evaluated in fetuses with hepatic hilar cyst. Prenatal ultrasound findings could provide suggestive parameters for the differential diagnosis of CBA from CC.

Abstract
A 126-day female child presented with jaundice since day 7 of life. She was icteric and had hepatosplenomegaly. Radiological investigations revealed three extrahepatic and multiple intrahepatic biliary cysts, absent gall bladder and portal vein. These findings were confirmed on laparotomy. To the best of our knowledge, this is the first report of cystic biliary atresia associated with congenital absence of portal vein.

Abstract
Introduction: Both cystic biliary atresia and choledochal cyst present as infantile obstructive cholangiopathy. Methods: We detail an infant with congenital biliary dilatation and obstructive cholangiopathy where clinicoradiological features (antenatally imaged subhepatic cyst, early onset jaundice, intrahepatic dilated biliary radicals) suggested a choledochal cyst but operative findings (lack of a distal communication of cyst with duodenum) and histomorphological features (cicatricial collagen and myofibroblastic hyperplasia in the cyst wall; ductal plate malformation, ductular cholestasis and strong expression of CD56 in the liver) were those associated with biliary atresia. Conclusion: The observations support the contention that BA and CC may be interim entities in a continuum of manifestation of the same pathology.

Abstract
Background In biliary atresia, the disease process of obliterative cholangiopathy may begin in the perinatal period; however, no chronological evidence exists on how the cholangiopathy progresses to biliary obliteration. This is the first acquired case with the final diagnosis of type III cystic biliary atresia with an extrahepatic biliary cyst which showed the progression of obliterative cholangiopathy in chronological order after birth. Case presentation An 81-day-old girl presented with acute abdominal distress due to bilious peritonitis caused by biliary cyst perforation, for which she underwent emergency biliary drainage. Postoperative images showed a dilated common bile duct and hepatic ducts bilaterally, with flow of the contrast medium to the duodenum through the dilated common bile duct. Biochemistry of the bile collected during and after the operation revealed elevated levels of pancreatic enzymes in the bile from the gallbladder. The patient was diagnosed as having a congenital choledochal cyst and underwent laparotomy at 120 days of age which revealed that she had pancreaticobiliary maljunction. The biliary cyst was resected at the narrow portion just above the junction with the main pancreatic duct. During dissection up to the hepatic hilum, we found that the hilar hepatic ducts were bilaterally replaced by fibrous tissue and were obstructed, leading to a diagnosis of type III a1, μ biliary atresia. The fibrous tissue was excised, and hepatic portoenterostomy was performed according to the Kasai procedure. The patient’s postoperative course was uneventful and the jaundice resolved within 1 month. She has had normal liver function tests with no episode of cholangitis for 3 years after discharge. Conclusions We demonstrated the process of acquired type III biliary atresia in a patient with cystic biliary atresia and biliary cyst perforation. To the best of our knowledge, this is the first case of acquired cystic biliary atresia showing chronological progression of the course of obliterative cholangiopathy, providing a better understanding of the development of type III biliary atresia as an acquired disease.

Abstract
Pediatric gallbladder and bile duct disease encompasses a broad spectrum of processes, from congenital to developmental to neoplastic. We describe normal pediatric biliary anatomy and summarize the most common pathologic entities, with a focus on non-invasive imaging techniques and findings. Ultrasound is the first-line imaging modality in children with suspected biliary pathology based on its widespread availability, cost effectiveness, and lack of ionizing radiation. MRI and MRCP are often used for further evaluation in cases of diagnostic uncertainty and for surgical planning.

Abstract
Biliary atresia is a severe cholangiopathy of early infancy that destroys extrahepatic bile ducts and disrupts bile flow. With a poorly defined disease pathogenesis, treatment consists of the surgical removal of duct remnants followed by hepatoportoenterostomy. Although this approach can improve the short-term outcome, the liver disease progresses to end-stage cirrhosis in most children. Further improvement in outcome will require a greater understanding of the mechanisms of biliary injury and fibrosis. Here, we review progress in the field, which has been fuelled by collaborative studies in larger patient cohorts and the development of cell culture and animal model systems to directly test hypotheses. Advances include the identification of phenotypic subgroups and stages of disease based on clinical, pathological and molecular features. Stronger evidence exists for viruses, toxins and gene sequence variations in the aetiology of biliary atresia, triggering a proinflammatory response that injures the duct epithelium and produces a rapidly progressive cholangiopathy. The immune response also activates the expression of type 2 cytokines that promote epithelial cell proliferation and extracellular matrix production by nonparenchymal cells. These advances provide insight into phenotype variability and might be relevant to the design of personalized trials to block progression of liver disease.

Abstract
Extrahepatic biliary atresia (EHBA) is an uncommon cause of neonatal jaundice. Antenatal Magnetic Resonance Imaging (MRI) diagnosis of EHBA has not been published to the best of our knowledge till date. EHBA with cystic component is likely to be mistaken for choledochal cyst. A case that was antenatally predicted and postnatally confirmed by surgery and histopathology is being reported. All imaging signs are analyzed herewith. Imaging helps in the prediction of EHBA and also helps in early postnatal surgical referral which in turn improves the results of Kasai's portoenterostomy.

Abstract
AIM To investigate the ultrasound findings associated with early liver transplantation (LT) after Kasai portoenterostomy (Kasai) in children with biliary atresia (BA). MATERIALS AND METHODS Children with BA (n = 30) who underwent Kasai were classified into early LT group (n = 17, LT within 1 year after Kasai) and Kasai alone group (n = 13, alive with their native livers). Serial ultrasound (baseline and follow-up before LT or post-Kasai 1 year) images were reviewed to investigate significant ultrasound findings related to early LT using both univariate and multivariate models. Images were reviewed focusing on the hepatic artery diameter, portal vein diameter, and signs of portal hypertension. RESULTS The hepatic artery diameters in the early LT group were significantly larger than those in the Kasai alone group both at baseline (p = 0.007) and follow-up ultrasound (p < 0.001). The portal vein diameters on follow-up ultrasound were smaller in the early LT group than the Kasai alone group (p < 0.001). On multivariate analysis, baseline hepatic artery diameter (hazard ratio, 20.4; 95% confidence interval, 3.7-110.6; p < 0.001) and the presence of splenomegaly at follow-up ultrasound (17.7; 2.6-121.8; p = 0.004) were significant predictors associated with early LT. The optimal cut-off value of the baseline hepatic artery diameter was 1.9 mm (82% sensitivity and 77% specificity). CONCLUSION Enlarged hepatic artery at baseline ultrasound and the presence of splenomegaly at follow-up ultrasound were associated with early LT after Kasai in children with BA.

Abstract
Gallbladder agenesis is a rare congenital anomaly. Choledochal cysts are uncommon. The combination of both these entities in a 56-year-old woman is reported. A previously fit and well woman, presented to the emergency department with a 3-day history of abdominal pain. Preoperative imaging and intraoperative findings confirmed gallbladder agenesis and a type I choledochal cyst. There were no other anomalies. She underwent a resection of the choledochal cyst and reconstruction by hepaticojejunostomy.

Abstract
Biliary cysts (BC) are rare dilatations of different parts of a biliary tract. They account for approximately 1% of all benign biliary diseases. BC occur the most frequently in Asian and female populations. They are an important problem for pediatricians, gastroenterologists, radiologists and surgeons. Clinical presentation and management depend on the BC type. Cholangiocarcinoma is the most serious and dangerous BC complication. The other complications associated with BC involve cholelithiasis and hepatolithiasis, cholangitis, acute and chronic pancreatitis, portal hypertension, liver fibrosis and secondary liver cirrhosis and spontaneous cyst perforation. Different BC classifications have been described in the literature. Todani classification dividing BC into five types is the most useful in clinical practice. The early diagnosis and proper treatment are very important, because BC are associated with a risk of carcinogenesis. A malignancy risk increases with the age. Radiological investigations (ultrasonography, computed tomography, endoscopic retrograde cholangiopancreatography and magnetic resonance cholangiopancreatography) play an important role in BC diagnostics. Currently, prenatal diagnosis using ultrasonography is possible. It allows to differentiate biliary disorders in fetals and to perform the early surgical treatment that improves results. In most patients, total cyst excision with Roux-Y hepaticojejunostomy is the treatment of choice. Surgical treatment of BC is associated with high success rate and low morbidity and mortality. The early treatment is associated with a lower number of complications. Patients following BC surgery require permanent and careful postoperative observation using laboratory and imaging investigations because of possibility of biliary anastomosis stricture and biliary cancer in tissue remnant.

Abstract
Biliary atresia is the most common cholangiopathy of childhood. With complete obstruction of segments or the entire length of extrahepatic bile ducts, the timely pursuit of hepatoportoenterostomy is the best strategy to restore bile drainage. However, even with prompt surgical intervention, ongoing injury of intrahepatic bile ducts and progressive cholangiopathy lead to end-stage cirrhosis. The pace of disease progression is not uniform; it may relate to clinical forms of disease and/or staging of liver pathology at diagnosis. Although the etiology of disease is not yet defined, several biological processes have been linked to pathogenic mechanisms of bile duct injury. Among them, there is increasing evidence that the immune system targets the duct epithelium and disrupts bile flow. We discuss how careful clinical phenotyping, staging of disease, and basic mechanistic research are providing insights into clinical trial designs and directions for development of new therapies to block progression of disease.

Abstract
Biliary atresia and related disorders of the biliary tree, such as choledochal cyst, must be considered in the differential diagnosis of prolonged conjugated hyperbilirubinemia in infants and children. Pediatric biliary tract diseases include a variety of entities with a wide range of clinical presentations. Radiology plays an important role in the diagnosis and management of these pathologies. Unrecognized causes of biliary disease, like biliary atresia, can lead to liver transplantation during the first year of life. The aim of this article is to review the imaging of pediatric biliary disorders, including the implications of interventional radiology in some biliary diseases.

Abstract
BACKGROUND Biliary atresia (BA) with hilar cyst is an uncommon variant, which constitutes less than 10% of all types of BA, and the operative procedure for this type of BA remains controversial. METHODS We have had 200 cases with BA from 1963 to 2008 in our institute and our branch hospitals, in which 12 cases (6%) were BA with a hilar cyst. The clinical records of all cases were evaluated retrospectively. RESULTS Twelve BA patients with a hilar cyst included 2 boys and 10 girls. The diagnosis of BA was confirmed by intraoperative cholangiography (cloudy or treelike pattern). In all 12 cases, a hepaticojejunostomy was performed at a median age of 71.6 days (range, 24-136 days). The follow-up periods were 1.2 to 23.2 years. The current mean total bilirubin level was 0.8 mg/dL (range, 0.2-3.5 mg/dL), and the mean direct bilirubin level was 0.2 mg/dL (range, 0.0 to 0.8 mg/dL). Methylprednisolone or oral prednisolone was administered in 8 cases after operation, and 10 of 12 cases achieved a jaundice free state. The postoperative complications were cholangitis (n = 10), gastroesophageal varices (n = 7), splenomegaly (n = 3), ileus (n = 1), and pulmonary hypertension (n = 1). The overall survival rate with a native liver was 10 (83.3%) of 12 cases, of which 9 cases were jaundice-free and only 1 case showed recurrent jaundice. The other 2 cases underwent living-donor liver transplantation at age of 2 and 20 years, respectively, and they are currently doing well. CONCLUSIONS Most cases of BA with a hilar cyst achieved excellent clinical outcome after a hepaticojejunostomy.

Abstract
Biliary atresia (BA) is a progressive fibro-obliterative disease of the extrahepatic biliary tree that presents with biliary obstruction in the neonatal period. Untreated, BA is a uniformly fatal disease and, yet, even with our existing therapies, at least 50% of children with BA will undergo liver transplantation by the age of 2 years. Current treatment strategies are, at best, palliative; they focus on prompt diagnosis, supportive nutritional care and interventions for sequelae. The purpose of this article is to discuss the current treatment paradigm for BA and to assess the impact these strategies have on outcomes. As more children with BA survive into adulthood with their native liver, it is important to understand which factors predict good and poor outcomes.

Abstract
BACKGROUND Biliary atresia (BA) is a progressive fibro-obliterative disease of the extrahepatic biliary tree that presents with biliary obstruction before 2 months of age. Untreated BA is a uniformly fatal disease and even with our current therapies only 50% of children with BA will be transplant-free by 2 years of age. Despite descriptions of this disorder dating back to the 1800s our current therapies are palliative. They focus on prompt diagnosis, supportive nutritional care and interventions for sequelae. OBJECTIVE To present the literature supporting current treatment strategies and potential future therapies. METHOD Each of the aspects of care is described and the literature about nuances of care is provided. CONCLUSION Therapies will not improve outcomes until novel treatments are introduced, such as those suggested, which may intervene in the inflammatory or fibrotic steps of the disease process.

Abstract
INTRODUCTION Cystic biliary atresia (CBA) is an uncommon variant of biliary atresia (BA) in which prognosis may be relatively favorable but liable to misdiagnosis as choledochal cyst, and potentially offers insights into the etiology of BA. Because some cases can be detected antenatally, CBA in general may have its origins in utero life. We assessed our experience with CBA. METHODS Single-center retrospective review of infants with CBA over a 13-year period (January 1994 to December 2006) was done. Data are given as medians (range). RESULTS Of 270 infants with BA, 29 (9 male) were identified as CBA. Antenatal ultrasonography had detected an abnormality in 12 (41%) infants at a median of 22 weeks (17-34 weeks) of gestation. All infants underwent postnatal excision and Kasai portoenterostomy (KP). Those with antenatally detected CBA came to surgery younger (36 [14-67] vs 48 days [35-147 days], P = .004). Twenty cysts (69%) had a fibroinflammatory wall with no biliary epithelial lining and 6 (26%) contained bile. Age at KP was significantly and positively correlated (r = 0.46, P = .01) with liver fibrosis, as assessed in liver biopsy materials obtained at KP, but not with grade of "hepatocyte disarray" (P = .74). Twenty infants (69%) cleared their jaundice (bilirubin <20 mumol/L) within 6 months after KP. Age at KP markedly affected outcome. CONCLUSION Cystic BA is a clinically distinct variant of BA. Despite onset in prenatal life, earlier than presumed for isolated BA, it has a better prognosis, particularly with early surgery.

Abstract
Although advances in the management of children with congenital cholestasis have enabled many to survive into adulthood with their native livers, even the most common of these conditions remains rare in adult hepatology practice. Among four congenital cholestatic syndromes (biliary atresia, Alagille syndrome, Caroli disease and congenital hepatic fibrosis, and progressive familial intrahepatic cholestasis), the published data on outcomes of the syndromes into adulthood suggest that a spectrum of severity of liver disease can be expected, from cirrhosis (almost universal in adults with biliary atresia who have not required liver transplantation) to mild and subclinical (eg, in the previously undiagnosed affected parent of an infant with Alagille syndrome). Complications associated with portal hypertension and nutritional deficiencies are common, and other associated features of the cholestatic syndrome may require appropriate attention, such as congenital heart disease in Alagille syndrome. Indications for liver transplantation include synthetic failure, progressive encephalopathy, intractable pruritus, recurrent biliary sepsis and recurrent complications of portal hypertension. Improved understanding of biliary physiology will hopefully translate into improved therapy for children and adults with cholestasis.

Abstract
OBJECTIVE To study the clinical presentation, management and results of treatment of 41 consecutive cases of choledochal cyst (CC) managed from 1999 to 2006. METHODS The age of the patients ranged from 20 days to 11 years. Eleven cases were 1 year or less in age (infantile group) and 30 patients were more than 1 year old (classical pediatric group). Children less than 1 year old presented with jaundice (72%), hepatomegaly (54%) and clay-colored stools (63%); whereas those above one year in age presented with pain (83.3%) and jaundice (47.6%). Three cases had biliary perforation with localized or generalized biliary peritonitis. Ultrasonography (US) diagnosed/suggested CC in all 41 patients, however, contrast-enhanced computed tomographic (CECT) scan (n=12), radionuclide DISIDA scan (n=5) and magnetic resonance cholangiopancreatogram (MRCP) (n=3) also contributed to the diagnosis. 19 patients, including 4 from the 'infantile' group, had significant dilatation of intrahepatic biliary ducts. RESULTS Nine patients from the 'infantile' group had cystic type I CC (type Ic), while 2 patients had fusiform dilatation of the common bile duct (type If disease). In contrast, 21 of the older patients had type If disease while 9 had type Ic disease. Operative management included primary complete excision of the cyst with a Roux-en-Y hepaticodochojejunostomy (HDJ) (n=32), Lilly's modification of submucosal resection with a HDJ (n=8) and cyst excision with a hepaticodochoduodenostomy (HDD) (n=1). All 3 patients with biliary perforation had primary excision of the CC with a HDJ. Unusual operative findings included accessory hepatic ducts (n=2), anteriorly placed common or right hepatic arteries (n=3) and partially or completely blocked proximal extrahepatic bile ducts (n=3). There were 2 postoperative deaths, one had cirrhotic liver disease with portal hypertension, the other had deep icterus with poor general condition. Both patients succumbed to overwhelming sepsis. One patient required reexploration and refashioning of the HDJ for biliary leak. Short-term follow-up was satisfactory in all 39 patients. CONCLUSION Infants with CC constitute a distinct group with regard to clinical presentation and the pathological should be kept in mind while evaluating neonates and infants with cholestatic jaundice and older children with recurrent abdominal pain. Primary excision of the cyst with a HDJ provides satisfactory results in the management of the vast majority of cases of CC including those in infants, massive CC and in the presence of biliary perforation and peritonitis.
