A case series of prenatal hepatic hilar cyst in the presence of a gallbladder - navigating the dilemma between biliary atresia and choledochal cyst. BMC Pediatr 2024; 24:580.

Abstract
BACKGROUND Prenatally diagnosed hepatic hilar cysts are a challenging finding for the clinician. They can either be a sign of cystic biliary atresia (BA) or a choledochal cyst (CC), two diagnoses with different postnatal management and prognosis. Based on a case report of four patients, we aim to propose a management algorithm for prenatally diagnosed "hepatic hilar cysts". CASE PRESENTATION A hepatic hilar cyst, ranging from 5 to 25 mm, was detected prenatally in all four girls confirmed postnatally along with the presence of a gallbladder. Stool color was normal until two weeks of life at which time the stool color became lighter, and the patients developed cholestasis. All were operated before seven weeks of life: Case 1 had a CC with patent but irregular intrahepatic bile ducts at intraoperative cholangiogram, and no communication with the duodenum. A Roux-en-Y bilioenteric anastomosis was performed. The cyst showed complete epithelial lining loss, and liver pathology showed BA features. Case 2 had the final diagnosis of cystic BA with patent but abnormal intrahepatic bile ducts. She underwent two operations: the first operation at four weeks as described for case 1, since intraoperative findings were similar, as was histology. As cholestasis increased postoperatively, she underwent a Kasai hepato-porto-enterostomy six weeks later, where distinct BA findings were found with complete scarring of the hilar plate. Case 3 had a cystic BA with the cyst located within the common bile duct and atretic bile ducts proximal to the porta hepatis. It exhibited no communication with the liver or duodenum. A Kasai operation was performed, with histology showing complete epithelial loss within the cyst wall and scarring of the hilar plate. Case 4 had a cystic BA presenting a completely obliterated hepatic duct with the cyst lying within the common bile duct. A Kasai procedure was performed. Histology showed a common bile duct with a residual lumen of 0.1 mm. CONCLUSIONS The spectrum of disease from CC to BA in the setting of a prenatally discovered hepatic hilar cyst is emphasized. Even if cholangiogram differentiates most patients with BA from those with CC, caution is advised for transitional types.

Biliary Atresia: Clinical Phenotypes and Aetiological Heterogeneity. J Clin Med 2021; 10:jcm10235675.

Abstract
Biliary atresia (BA) is an obliterative condition of the biliary tract that presents with persistent jaundice and pale stools typically in the first few weeks of life. While this phenotypic signature may be broadly similar by the time of presentation, it is likely that this is only the final common pathway with a number of possible preceding causative factors and disparate pathogenic mechanisms-i.e., aetiological heterogeneity. Certainly, there are distinguishable variants which suggest a higher degree of aetiological homogeneity such as the syndromic variants of biliary atresia splenic malformation or cat-eye syndrome, which implicate an early developmental mechanism. In others, the presence of synchronous viral infection also make this plausible as an aetiological agent though it is likely that disease onset is from the perinatal period. In the majority of cases, currently termed isolated BA, there are still too few clues as to aetiology or indeed pathogenesis.

Abstract
A choledochal cyst is a rare abdominal malformation and was first reported almost three centuries before. There are few theories describing the evolution of the cyst through the lifespan of affected patients until diagnosis and prompt treatment; however, there is no image documentation of the evolution of the malformation. In this report, we demonstrate the evolution of a type I choledochal cyst in a fetus from the 24th to the 37th week of gestation using magnetic resonance imaging and perinatal outcomes with correlation with pathophysiological mechanisms.

Abstract
Liver and biliary pathology in the neonate are rare and include a broad range of structural, neoplastic, infectious, genetic, and metabolic diseases. While most conditions present postnatally, antenatal detection is increasing given recent advances in antenatal imaging capabilities. In certain structural or obstructive liver diseases, antenatal detection now proves essential to help guide treatment and prevent morbidity. We review the epidemiology, pathophysiology, common antenatal diagnostic findings, and recommendations for surgical liver and biliary pathology in the neonate.

Abstract
Neonatal obstructive jaundice is frequently explained by biliary atresia (BA) or the presence of a choledochal cyst (CC). Cystic biliary atresia (CBA) has been a proposed as a subtype of BA with projected improved outcomes. We aimed to characterize these lesions further. We conducted an Institutional Review Board-approved review of all patients treated for obstructive jaundice at our tertiary children's hospital over 10 years. Over the decade we evaluated 91 children with obstructive jaundice: 13 CBA, 52 BA, and 26 CC. Patients with isolated CBA and BA were diagnosed significantly earlier than those with CC (15.9, 54, and 281 days, respectively; P = 0.0001). There was a significant delay between diagnosis and surgical intervention for patients with CBA compared with BA: 17 days versus 5.7 days ( P = 0.004). There was no difference in rate of transplant between CBA and BA (31 vs 50%; P = 0.35). The time from surgery until transplant was 13.9 and 18.6 months for CBA and BA, respectively ( P = 0.62). Although radiographically similar to CC, CBA behaves similarly to isolated BA. Delay in recognition and surgical treatment may affect outcomes and lead to an increased incidence of liver failure. The presence of a cystic biliary malformation in the setting of neonatal jaundice should be regarded as CBA until proven otherwise.

Abstract
Biliary atresia (BA) is the most common reason for pediatric liver transplant. BA's varied presentation, natural history, and treatment with the Kasai portoenterostomy have been well described; however, when BA starts relative to birth has not been clearly defined. In this review, we discuss laboratory, imaging, and clinical data which suggest that most if not all forms of BA may start before birth. This early onset has implications in terms of delivering treatments earlier and identifying possible factors underlying BA's etiology.

Abstract
Congenital anomalies of the biliary tract include a variety of pathologic conditions, such as biliary atresia, choledochal cysts, gallbladder agenesis, congenital cholelithiasis, and gallbladder duplication. Although most of these malformations are rare and benign conditions, they may occasionally represent a major threat to extrauterine life. Visualization of a normal-sized gallbladder should be a mandatory component of the second-trimester anomaly ultrasound scan. Advances in prenatal sonography enable the detection of biliary tract congenital malformations. In this review, we discuss the detection rates, sonographic features, and prognosis of the most frequently prenatally diagnosed biliary tract malformations.

Abstract
We present antenatal three-dimensional (3D) sonographic features of fetal biliary atresia. A 38-year-old pregnant Japanese woman was referred to our ultrasound clinic because of a fetal intra-abdominal cyst at 19 weeks of gestation. Conventional two-dimensional (2D) sonography and 3D sonography with an inversion mode showed a round cyst with a tiny dip in the subhepatic area. At 34 weeks, conventional 2D sonography and 3D sonography with inversion and transparent X-ray modes clearly revealed a round to oval cyst connected with the gallbladder via the cystic duct. A diagnosis of choledochal cyst (type I) was suggested antenatally. However, the final diagnosis made by employing operative cholangiography during surgery was biliary atresia (type I cyst) at 25 days of life. To the best of our knowledge, this is the first report of biliary atresia employing antenatal 3D sonography with inversion and transparent X-ray modes.

Abstract
OBJECTIVES Fetal gallbladder non-visualization on prenatal ultrasound in the second trimester is uncommon and in most cases the gallbladder is detected eventually. Associations of gallbladder non-visualization with cystic fibrosis, aneuploidy, agenesis of the gallbladder and biliary atresia have been reported. We present our experience and review the literature. METHODS During the study period from January 2004 to June 2009 we collected prospectively cases of non-visualization of the fetal gallbladder in the second trimester. In each case the fetus was evaluated by two examiners on at least two occasions, at least a week apart. Cases with no additional sonographic malformations were designated as isolated. Further evaluation included follow-up scans and a meticulous search for fetal anomalies. All patients were offered genetic consultation. Cystic fibrosis testing, amniocentesis for karyotyping and analysis of fetal digestive enzymes in the amniotic fluid were offered. RESULTS We collected 21 cases of non-visualization of the fetal gallbladder, 16 of which were isolated and five of which had additional malformations. In four of these five, the associated anomalies were severe and the pregnancies were terminated for aneuploidy (two cases of trisomy 18 and one triploidy) or for the severity of the associated anomalies. Associated anomalies included left isomerism with complex cardiac anomaly and intrauterine growth restriction with multisystem anomalies. The fifth fetus had interrupted inferior vena cava with azygos continuation without other anomalies and the child was alive and well at the age of 4 years. In 15 of the 16 isolated cases, antenatal and postnatal development were normal at the last follow-up, ranging from 4 months to 2.5 years. One case of cystic fibrosis was diagnosed prenatally and this pregnancy was terminated. There were no diagnoses of abnormal karyotype or biliary atresia among cases of isolated non-visualization of the gallbladder. CONCLUSIONS When prenatal non-visualization of the fetal gallbladder is associated with other severe malformation, aneuploidy should be suspected. When it is isolated, if cystic fibrosis is ruled out, the outcome is good.

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
BACKGROUND & AIMS To illustrate the limitations of the embryonic and perinatal classification system of biliary atresia (BA), we present a child with an antenatal diagnosis of choledochal cyst (CC) associated with BA and review the published literature. METHODS Medline and Pubmed were searched for "BA and CC," "cystic biliary atresia," "BA and cysts," and "biliary cystic malformations." RESULTS A 7-week-old with an antenatal diagnosis of CC was found to have BA associated with CC. The literature search identified 88 cases of BA with CC. Sixty-seven cases had type 1 BA (atresia of the common bile duct), 2 had type 2 BA (atresia of the common hepatic duct), and 19 had type 3 BA (atresia of the porta hepatis). Of the 27 cases of antenatal diagnosis of BA with CC only 1 had associated congenital anomalies. Outcome analysis showed poor outcomes were significantly more common (P = .009) and occurred earlier (P = .0249) in patients with type 3 BA. Children with type 3 BA were 5.4 times more likely to develop poor outcomes compared with type 1 (hazard ratio, 5.4; 95% confidence interval, 1.03-27.8). CONCLUSIONS BA associated with CC forms a distinct subtype of BA, characterized by a preponderance of type 1 BA, a relatively good clinical outcome after surgery, and an absence of associated congenital anomalies. Antenatal diagnosis of many affected infants supports their inclusion within the embryonic BA group and suggests that a broader interpretation of the embryonic phenotype and further classification of BA based on genetic susceptibility may be required.

Abstract
Biliary atresia is the single most common cause of chronic cholestasis in children and is the leading indication for liver transplantation worldwide. It results from an inflammatory and fibrosing obstruction of the extrahepatic bile ducts in the first few months of life. Early diagnosis and timely surgical portoenterostomy are necessary for improved biliary drainage, but the liver disease progresses to end-stage biliary cirrhosis in most patients. Although the pathogenesis of disease is largely unknown, recent patient- and animal-based experiments indicate interactions between infectious agents and inflammatory circuits may be important pathogenic mechanisms of disease.

Abstract
We describe a unique series of 3 cases of biliary atresia (BA) associated with a choledochal cyst. All 3 children presented with jaundice at birth and had no other abnormalities. Although these children had a fetal form of BA, their presentation and outcome differed from those of biliary atresia splenic malformation syndrome (BASM), the well-described form of early onset BA. Unlike those with BASM, these children had no other associated malformations, had a normal birth weight, and did not yet require a liver transplant. We believe that the present series of patients and their associated pathology may represent a distinct phenotype with a common, prenatally acquired etiology that is different from other fetal forms of BA, such as BASM, and from patients who present with the classic perinatal form of BA.

Abstract
Biliary atresia is a panbiliary disease causing obstructive jaundice in neonates and infants. The clinical spectrum can be broadly categorized into the fetal and perinatal types. A consistent animal model that accurately mimics the whole clinical spectrum of biliary atresia is not yet available. However, rotavirus infection of neonatal mice has been shown to produce atresia in the biliary system. This study investigates the three-dimensional computerized morphology of the murine neonatal model comparing with age-matched control mice. Newborn Balb/c mice were injected intraperitoneally with rhesus rotavirus within 24-48 h after birth. Control mice received 0.9% NaCl. Pups with symptoms of cholestasis were sacrificed from the 5th to the 15th postinjection day, as were age-matched controls. Their hepatobiliary tissues were prepared for three-dimensional computerized image reconstruction. Rotavirus infection caused obliteration of the intrahepatic bile ducts and single to multiple atresias in the extrahepatic bile duct. At 15 days postinjection, intrahepatic ductal proliferation appeared, and the three-dimensional appearances of the intrahepatic biliary structures were similar to the human disease. Cystic duct and gallbladder dilatation was frequently seen in this model, and this feature distinguishes it from the human disease in which the gallbladder is almost always atretic. This rotavirus murine model demonstrates many of the features of human perinatal biliary atresia, and can be used as an investigative tool to further study the pathogenesis of biliary atresia.

Abstract
A 2-month-old boy with biliary atresia (BA) with an extremely rare prenatal history is reported. A cystic lesion in the hepatic hilum was diagnosed during prenatal ultrasonography at 20 weeks' gestation. However, it disappeared during later prenatal observation. He was diagnosed with an uncorrectable type of BA after a massive subdural hemorrhage at the age of 66 days. A fetus suspected of having a cyst of the biliary tree should be followed even after the cyst has disappeared spontaneously.

Abstract
The diagnosis and detection of some forms of liver and bile duct disease have become possible since the adoption of routine fetal ultrasound scanning in the UK, and the remarkable advances in molecular biological techniques. Nevertheless, although antenatal detection may well have improved, it remains difficult to offer a specific diagnosis, much less a prognosis, in most cases. Cystic dilatation of the biliary tree is probably the most common finding. This may be due to cystic choledochal malformations or, occasionally but crucially, biliary atresia. Postnatal investigations (such as ultrasonography, magnetic resonance cholangiography and liver histology) must take the latter possibility into account, as early surgery is the key to a successful outcome following reconstructive biliary surgery. Antenatally diagnosed liver tumours are usually of vascular origin and have an unpredictable natural history. Some may cause fetal cardiac failure and are candidates for in-utero intervention, but in all likelihood, a large proportion will resolve without specific therapy.

Abstract
OBJECTIVES To investigate the incidence, presence of associated anomalies, type of malformation, and natural history of children with biliary atresia (BA) who presented antenatally. Study design The database of 194 infants diagnosed with BA at our tertiary referral unit between 1991 and 2002 was reviewed for infants in whom routine antenatal ultrasound had revealed biliary cystic malformations (BCMs). A retrospective analysis of their medical records was undertaken. RESULTS Nine infants (six girls) with BCM were identified (4.6% of total referred patients with BA); all were born after 37 weeks' gestational age and presented to us at a median age of 4 weeks (range, 1-14 weeks). The presence of the BCM was confirmed on postnatal ultrasonography. Median age at corrective surgery was 5 weeks (range, 2-16 weeks). At surgery, six patients had type III BA, including one with the biliary atresia-splenic malformation syndrome; two had type II BA; and one had type I BA. Postoperatively, the infants were followed for a median of 2 years (range, 6 months to 11 years). All infants successfully cleared their jaundice. CONCLUSIONS Improved techniques in routine antenatal ultrasonography can allow early recognition of BCM. This study suggests that BCM noted antenatally may represent early presentation of both biliary atresia-splenic malformation and nonsyndromic BA.

Abstract
BACKGROUND/PURPOSE Biliary tree cystic malformations (BCM) occur rarely. Current progress in ultrasonography makes it possible to identify them prenatally. The aim of this study was to analyze retrospectively prenatal ultrasound patterns of 5 consecutive subhepatic cysts in an effort to differentiate the BCM before birth and onset of symptoms. METHODS The prenatal ultrasound patterns of 5 consecutive BCM were correlated with the postnatal diagnosis. RESULTS Case 1 showed a hyperechogenic cyst that underwent enlargement during fetal life; the diagnosis at birth was an obstructed choledochal cyst (CC). In cases 2 and 3, an anechoic cyst with small, stable dimensions during pregnancy was identified; a biliary atresia (BA) type III-C was confirmed at birth. A slightly hyperechogenic cyst with no increase in size at repeated prenatal scans, was observed in cases 4 and 5; a CC and a cystic lesion at the confluence of the hepatic ducts (without obstruction) were diagnosed postnatally, respectively. CONCLUSIONS The ultrasound scan pattern and size allow to make a prenatal differential diagnosis of BCM. Anechoic, small cyst in the hepatic hilum is highly suspicious for BA. Large, echoic or enlarging cyst is strongly suggestive of "obstructed" CC. Echoic, small and stable cyst is more suggestive of "unobstructed" CC.

Abstract
BACKGROUND Although congenital biliary tree abnormalities are uncommon in the United States, more are being diagnosed antenatally with improved imaging techniques. METHODS To determine the prognosis of prenatally diagnosed biliary disease, the authors reviewed the treatment of 3 children who had biliary cystic lesions found during routine prenatal ultrasonography. RESULTS All 3 children were born at term. They had elevated bilirubin levels, and postnatal ultrasound scans confirmed the presence of a biliary cystic mass. They underwent exploration within 2 weeks of life. At operation, 2 children were found to have biliary atresia with a cystic biliary lesion. They underwent Kasai procedures and are doing well at 5 and 9 months of age. The third child was found to have a type I choledochal cyst and malrotation at exploration. He underwent cystectomy with Roux-en-Y hepaticojejunostomy and a Ladd's procedure and is doing well at 3 years of age. CONCLUSIONS Prenatally diagnosed biliary cysts represent a different spectrum of disease than those diagnosed later in life. The sequelae of biliary disease start before birth, and early operation may be necessary to achieve a good outcome. Because it is impossible to distinguish between choledochal cysts and biliary atresia on antenatal ultrasound scan or magnetic resonance imaging, children with presumed choledochal cysts should undergo early exploration to rule out potential biliary atresia. Excellent outcome is possible with early operation in the absence of severe associated anomalies.

Abstract
The combination of portoenterostomy with subsequent liver transplantation is the treatment of choice for patients with biliary atresia. It is important, however, to attempt to keep the patient's own organ by continuing efforts to achieve the best possible results with portoenterostomy. Additional basic research, perhaps concerning on the role of cytokines and apoptosis in the control of biliary atresia, may provide insight into possible new medical strategies for treating patients with biliary atresia. For example, in addition to portoenterostomy, control of apoptosis at various cellular levels and of bile duct cell proliferation and maturation by manipulation of the growth factors and cytokines may become part of future treatment modalities. Another direction of research should be the control of fibrogenesis, which might be accomplished by blocking TGF-beta 1 and platelet-derived growth factor and by HGF gene therapy. The author's current strategy for surgical treatment for patients with biliary atresia include (1) early diagnosis, including prenatal diagnosis and broader use of mass screening programs, (2) hepatic portoenterostomy, without stoma formation; (3) close postoperative care, especially for prevention of postoperative cholangitis; (4) revision of portoenterostomy only in selected cases; (5) early liver transplantation in patients with absolutely failed portoenterostomy; (6) avoidance of laparotomy for the treatment of esophageal varices and hypersplenism; (7) consideration of exploratory laparotomy or primary liver transplantation for patients with advanced liver disease at the time of referral. The development of new treatment modalities based on the understanding of the pathogenesis of the disease, and especially on the biology of intrahepatic bile ducts and hepatic fibrosis, is essential.

Abstract
BACKGROUND The accuracy of the technique of antenatal ultrasonography in the diagnosis of congenital bile duct lesions is unknown. METHODS Thirteen patients with proven biliary disease who had abnormal antenatal scans were reviewed. Two infants had type I cystic biliary atresia and one had a noncommunicating segmental dilatation of the bile duct in a type 3 biliary atresia. The remainder had choledochal cysts and included two patients with intrahepatic cysts. The correct diagnosis was made antenatally in only two (15%) cases. Of the remaining patients, seven received a diagnosis of intraabdominal cysts of unknown etiology, three of duodenal atresia, and one ovarian cyst. The median gestational age at the antenatal diagnosis was 20 weeks. RESULTS Jaundice developed in 11 infants, and dilatation of intrahepatic biliary radicals was noted in four of the choledochal cysts. Obstructive jaundice and increasing cyst size were indications for early surgery, and twelve infants underwent a laparotomy at a median age of 4 weeks. During the median follow-up period of 2 years, 12 of the 13 patients have lost their jaundice or remained anicteric. Antenatal diagnosis offers the possibility of early definitive surgery for uncomplicated choledochal dilatation and the chance of improved outcome for surgically treated biliary atresia. An algorithm is suggested for the management of antenatally detected cystic biliary lesions.

Abstract
The cause of extrahepatic biliary atresia (EHBA) remains unknown, and even an animal model is still lacking. Observations in a murine infectious model (newborn Balb/c mice infected with rhesus rotavirus group A [RRV]) reported extrahepatic biliary obstruction similar to findings in children who have EHBA. In the present study, this animal experiment was repeated, and the clinical and histomorphologic changes were observed over 3 weeks. Eighty-nine newborn mice were infected with RRV, and 67% showed signs of cholestasis and delayed growth. Eight of these animals recovered spontaneously whereas the others remained icteric. Fourty-six pups were prepared for microscopic examination following a 2-day interval. From the fifth day, the whole biliary tract showed edematous swelling with cellular infiltration. Ten days later, in the extrahepatic bile duct, a transformation took place in which concentric infiltration led to complete obstruction, sometimes with prestenotic dilatation. The intrahepatic changes showed reactive necrosis and proliferation of the small bile ducts. In one 19-day-old mouse, a ballooning dilatation was observed, similar to a developing choledochal cyst. Infection with RRV induces in newborn Balb/c mice a cholestatic clinical picture with different courses of the disease leading mostly to complete biliary obstruction and secondary hepatic changes similar to EHBA in children. This is the first animal model for EHBA with complete obstruction of the extrahepatic bile duct induced by infection. These findings present a new basis for further studies.
