Abstract
BACKGROUND To predict native liver survival (NLS) after Kasai portoenterostomy (KP) for biliary atresia (BA) using pre-operative clinical data. MATERIALS AND METHODS Pre-operative data were collected from 29 patients with BA who underwent KP at our department between 1989 and 2017 and were analysed including serum albumin, bilirubin, prothrombin time-international normalised ratio, body height, body weight, age at KP, paediatric end-stage liver disease score calculated using the pre-operative data and the period of NLS. RESULTS The 10-year NLS rate of all patients was 51%. A multivariate analysis revealed that among all factors, the pre-KP serum albumin level was the only independent predictor of NLS ( P = 0.04, hazard ratio = 0.269, 95% confidence interval = 0.077-0.934). The area under the receiver operating characteristic curve for NLS, determined using pre-KP serum albumin was 0.760 and 3.75 mg/dl was selected as the cut-off value. There was a significant difference in NLS between patients with high (≥3.8 mg/dl) and low (≤3.7 mg/dl) pre-KP serum albumin (90.0% vs. 31.5%, P < 0.01). CONCLUSIONS Decreased pre-KP serum albumin may reflect not only functional impairment of the liver, but also the inflammatory process, which is hypothesized to occur during its advancement. The pre-KP serum albumin level may be a good prognostic factor for NLS in post-KP BA patients.

Lu C, Xie H, Zhu Z, Ding Z, Geng Q, Tang W. A convenient nomogram for predicting early death or liver transplantation after the Kasai procedure in patients with biliary atresia. Langenbecks Arch Surg 2024; 409:30. [PMID: 38189999 DOI: 10.1007/s00423-023-03216-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Accepted: 12/28/2023] [Indexed: 01/09/2024]
Abstract
PURPOSE Many patients with biliary atresia (BA) after the Kasai procedure (KP) progress to death or require liver transplantation to achieve long-term survival; however, most cases of death/liver transplantation (D/LT) occur in the early period after KP (usually within 1 year). This study was designed to construct a convenient nomogram for predicting early D/LT in patients with BA after KP. METHODS A BA cohort was established in May 2017, and up to May 2023, 112 patients with 1-5 years of follow-up were enrolled in the study and randomly (ratio, 3:1) divided into a training cohort for constructing a nomogram (n = 84) and a validation cohort (n = 28) for externally validating the discrimination and calibration. The training cohort was divided into two groups: the early D/LT group (patients who died or had undergone LT within 1 year after KP [n = 35]) and the control group (patients who survived through the native liver more than 1 year after KP [n = 49]). Multivariate logistic regression and stepwise regression were applied to detect variables with the best predictive ability for the construction of the nomogram. The discrimination and calibration of the nomogram were internally and externally validated. RESULTS The Kaplan-Meier (K-M) curve showed an actual 1-year native liver transplantation (NLS) rate of 57.1% and an estimated 2-year NLS rate of 55.2%. By multivariate regression and stepwise regression, age at KP, jaundice clearance (JC) speed 1 month after KP, early-onset PC (initial time < 36.5 days) after KP, sex, aspartate aminotransferase-to-platelet ratio index (APRI), and weight at KP were identified as the independent variables with the best ability to predict early D/LT and were used to construct a nomogram. The developed nomogram based on these independent variables showed relatively good discrimination and calibration according to internal and external validation. CONCLUSION Most D/LTs were early D/LTs that occurred within 1 year after KP. The established nomogram based on predictors, including sex, weight at the KP, the APRI, age at the KP, JC speed 1 month after the KP, and early PC, may be useful for predicting early D/LT and may be helpful for counseling BA patients about patient prognosis after KP. This study was retrospectively registered at ClinicalTrials.gov (NCT05909033) in June 2023.

Abstract
BACKGROUND This study examines the results of liver transplantation (LT) in patients with biliary atresia, considering whether they underwent the Kasai procedure beforehand. LT and determine postoperative and long-term graft outcomes. METHODS This single-center, retrospective study included 72 pediatric patients diagnosed with postpartum biliary atresia who underwent LT between 2010 and 2022. We included patients who underwent LT either after or without the Kasai procedure and compared the demographic data of the patients with various factors, such as the Pediatric End-Stage Liver Disease scores and laboratory values. RESULTS The study included 72 patients, with 39 of them being female (54.2%) and 33 of them being male (45.8%). Of the 72 patients in the study, 47 (65.3%) had undergone the Kasai procedure, and 25 (34.7%) had not. The preoperative and postoperative month 1 bilirubin values were lower in patients who underwent the Kasai procedure and were higher in postoperative months 3 and 6. Preoperative bilirubin values, postoperative month 3 bilirubin values, and preoperative albumin values were higher in patients who developed mortality (P < .05). Cold ischemia time was longer in patients who developed mortality (P < .05). CONCLUSIONS Our study showed a higher mortality rate in patients who underwent the Kasai procedure. The results also showed that LT was more effective in children, as patients with Kasai had higher mean bilirubin values and higher preoperative albumin values than patients without Kasai.

Abstract
BACKGROUND The appropriate timing of liver transplantation (LT) in patients with biliary atresia (BA) who survived with their native livers until adolescence remains controversial. The liver-spleen volume ratio (LSR) has been reported to be efficacious in predicting the prognosis of chronic liver disease. We investigated whether LSR could predict long-term native liver prognosis and serve as an indication for LT in patients with BA. METHODS Patients with BA who survived with their native liver until the age of 15 years were included. These patients were classified into 2 groups. The unfavorable prognosis group included patients who underwent or were awaiting LT or developed complications such as refractory cholangitis or gastrointestinal bleeding due to esophagogastric or intestinal varices. The favorable prognosis group included patients who survived with their native liver without complications. We compared the 2 groups regarding LSR, hematological, and histologic data. RESULTS Of 19 patients, 8 were in the unfavorable prognosis group, and 11 were in the favorable prognosis group. LSR was significantly lower in the unfavorable prognosis group (P = .009). Analysis of the receiver operating characteristic curve showed that the area under the curve of the LSR was 0.891, which was higher than the area under the curve of liver fibrosis markers. The optimal LSR cut-off value for predicting poor native liver prognosis was 1.97, with a sensitivity of 75.0% and a specificity of 87.5%. CONCLUSIONS The LSR reflects splenomegaly and liver atrophy. The LSR might be a reliable predictor of native liver prognosis and could guide decisions about LT in patients with BA.

Abstract
OBJECTIVES To develop and validate a biliary atresia (BA) diagnostic score based on serum gamma-glutamyl transferase (GGT) levels and conventional ultrasound features for discriminating BA in patients with jaundice from two centers. METHODS A total of 958 patients from one hospital were classified as the derivation cohort, and 725 patients from another hospital were classified as the validation cohort. The optimal GGT cutoff value for diagnosing BA was calculated in the derivation cohort and subsequently verified in the validation cohort. Gallbladder abnormalities and the triangular cord (TC) sign were evaluated in all patients. A BA diagnostic score was developed for diagnosing BA using the GGT levels, gallbladder abnormalities and the TC sign based on the data from the derivation cohort followed by external validation. RESULTS Based on the optimal cutoff value 350.0 U/L, GGT yielded a sensitivity of 59.3% and specificity of 85.4% in diagnosing BA. The area under the receiver operating characteristic curve (AUC 0.724) was inferior to that of the gallbladder (AUC 0.911, P < .001) and comparable to that of the TC sign (AUC 0.771, P = .128). The combination of GGT and ultrasound diagnosis could help to reduce the misdiagnosis of 9 infants with BA. The BA diagnostic score yielded a sensitivity of 93.3% and specificity of 95.0% with the highest AUC in this study (0.941). CONCLUSIONS GGT can add diagnostic value to ultrasound examination when diagnosing BA. The BA diagnostic score based on GGT, gallbladder abnormalities and the TC sign shows satisfactory discrimination abilities in BA.

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
PURPOSE Biliary atresia is managed surgically by the Kasai portoenterostomy (KP). It has been reported by some groups that the outcomes of patients who have an early failed KP requiring a liver transplant (LTx) within the first year of life are worse than the outcomes of patients who undergo a primary LTx. The aim of this study was to identify preoperative parameters that could help predict what patients are at risk for the early failure of the procedure. MATERIALS AND METHODS We conducted a retrospective chart review of all patients who underwent a KP between January 2008 and May 2018. The following preoperative parameters were analyzed: age at KP, anatomical variant of the biliary atresia, degree of liver fibrosis, CMV status, and PELD score. The main outcome of the study was the early failure of the KP (EF-K), which was defined as the need for LTx before 1 year of age, or BA-related death before 1 year of age. Second, we analyzed the risk factors associated with death without LTx within the first year of life. RESULTS A total of 58 patients were included in the analysis. The native liver survival (NLS) was 56.5% and 48% at 1 and 5 years post KP, respectively. Overall survival (OS) was 79% and 76% at 1 and 5 years post KP, respectively. Early failure of KP occurred in 23 (39.7%) patients. OS in this group was 47% and 40% at 1 and 5 years, respectively. On the contrary, the OS of the remaining 35 (60.3%) patients was 100% at 1 and 5 years (P < 0.0001). When we compared all preoperative parameters, the only predictor of EF-K was the PELD score. When we analyzed the cases in the EF-K group who died without LTx, we found that the significant predictors were the cystic variant, a degree of liver fibrosis >4, and the PELD score. Nevertheless, on multivariate analysis, only PELD score was found as a statistically significant variable. CONCLUSION Due to bad prognosis found in EF-K patients, we believe that it could be reasonable to offer them a primary LTx. PELD score was found to be the strongest preoperative parameter that allows predicting which patient will likely have an early failed KP. Further prospective and multicenter studies are needed to reinforce these results.

Abstract
It is still challenging to make accurate diagnosis of biliary atresia (BA) with sonographic gallbladder images particularly in rural area without relevant expertise. To help diagnose BA based on sonographic gallbladder images, an ensembled deep learning model is developed. The model yields a patient-level sensitivity 93.1% and specificity 93.9% [with areas under the receiver operating characteristic curve of 0.956 (95% confidence interval: 0.928-0.977)] on the multi-center external validation dataset, superior to that of human experts. With the help of the model, the performances of human experts with various levels are improved. Moreover, the diagnosis based on smartphone photos of sonographic gallbladder images through a smartphone app and based on video sequences by the model still yields expert-level performances. The ensembled deep learning model in this study provides a solution to help radiologists improve the diagnosis of BA in various clinical application scenarios, particularly in rural and undeveloped regions with limited expertise.

Abstract
Several patient and treatment related factors significantly modify outcomes of biliary atresia. The extremely variable prognosis mandates intensive postoperative monitoring following portoenterostomy. Accurate prediction of outcome and progression of liver injury would enable individualized treatment and follow-up protocols, patient counseling and meaningful stratification of patients into clinical trials. While results on most biomarkers of cholestasis, hepatocyte function, fibrosis and inflammation studied so far are inconsistent or have not been validated in independent patient cohorts, postoperative serum bilirubin level 3 months after portoenterostomy remains the most accurate clinically feasible predictor of native liver survival. Although liver stiffness and a novel marker of cholangiocyte integrity, serum matrix metalloproteinase-7, correlate with liver fibrosis and may discriminate biliary atresia from other causes of neonatal cholestasis, further information on their ability to predict portoenterostomy outcomes is needed. Recent gene expression profiling has shown promise in overcoming the sampling error associated with histological quantification of liver fibrosis, and provides an important possibility to stratify patients for clinical trials according to the prognosis of native liver survival already preoperatively. As activity and extent of ductular reaction is linked with progression of liver fibrosis in cholangiopathies, further research is also warranted to evaluate predictive value of ductular reaction, matrix metalloproteinase-7 and the underlying gene expression signatures in relation to circulating bile acids in biliary atresia. Discovery of accurate predictive tools will ultimately increase our understanding of the unpredictable response to surgery and pathophysiology of progressive liver injury in biliary atresia.

Abstract
BACKGROUND Living donor liver transplantation (LDLT) in children has achieved promising outcomes during the past few decades. However, it still poses various challenges. This study aimed to analyze perioperative risk factors for postoperative death in pediatric LDLT. METHODS We retrospectively analyzed medical records of pediatric patients who underwent LDLT surgery from January 1, 2014, to December 31, 2016, in our hospital. Predictors of mortality following LDLT were analyzed in 430 children. Cox regression and Kaplan-Meier curve analysis were used for covariates selection. A nomogram was developed to estimate overall survival probability. The performance of the nomogram was assessed using calibration curve, decision curve analysis, and time-dependent receiver operating characteristic curve. RESULTS Among the 430 patients in this cohort (median [interquartile range] age, 7 [6.10] mo; 189 [43.9%] female; 391 [90.9%] biliary atresia), the overall survival was 91.4% (95% confidence interval, 89.2-94.4), and most of the death events (36/37) happened within 6 months after the surgery. Multivariate analysis indicated that the Pediatric End-stage Liver Disease score, neutrophil lymphocyte ratio, graft-to-recipient weight ratio, and intraoperative norepinephrine infusion were independent prognostic factors. A novel nomogram was developed based on these prognostic factors. The C index for the final model was 0.764 (95% confidence interval, 0.701-0.819). Decision curve analysis and time-dependent receiver operating characteristic curve suggested that this novel nomogram performed well at predicting mortality of pediatric LDLT. CONCLUSIONS We identified several perioperative risk factors for mortality of pediatric LDLT. And the newly developed nomogram can be a convenient individualized tool in estimating the prognosis of pediatric LDLT.

Abstract
Background Kasai procedure is the standard initial treatment of infants with biliary atresia. The key to perform a successful surgery is to accurately remove the fibrous portal plate near the liver hilum. Yet how to estimate surgical difficulty pre-operatively remains unclear. This study aims to design an algorithm that predicts the difficulty of Kasai procedure using liver stiffness measurement (LSM). Methods One hundred ninety-nine patients were included from April 2012 to December 2016. The patients were all surgically diagnosed with biliary atresia. Group A comprised of patients with porta hepatis retraction (the angle between the plane of the fibrous porta plate and the plane of the medial liver closest to the plate was equal to or smaller than 90°), group B comprised of patients without porta hepatis retraction (the angle between the plane of the fibrous porta plate and the plane of the medial liver closest to the plate was greater than 90°). Liver function measurements and LSM were measured for all patients within three days before surgery. Results Our study included 19 cases in group A (9 males, 10 females) and 180 cases in group B (87 males, 93 females). LSM had statistical differences between the two groups, 28.10(14.90) kPa VS 10.89(7.10) kPa, P = 0.000. There was a significant relationship between LSM and operative age, TBA, AST, GGT (P = 0.000, 0.003, 0.003, 0.012, correlation coefficient = 0.323, 0.213, 0.207, 0.179). The AUROC of LSM was 0.919. When the cutoff value was 15.15 kPa(OR = 3.989; P = 0.000), the sensitivity, specificity, PPV, NPV and diagnostic accuracy were 0.947, 0.750, 0.285, 0.992 and 0.768, respectively. When the value was 23.75 kPa(OR = 3.483; P = 0.000), the sensitivity, specificity, PPV, NPV and diagnostic accuracy were 0.631, 0.950, 0.571, 0.960 and 0.919, respectively. Conclusions LSM can be used to predict the difficulty in dissecting fibrous portal plate, and in turn, the difficulty of Kasai procedure. LSM > 23.75 kPa suggests a more complicated surgery.

Abstract
BACKGROUND The aim of this study was to retrospectively investigate whether Kasai Procedure (KP) improves nutritional status and whether KP decreases liver transplantation (LT)-associated complications in children with biliary atresia (BA). METHODS From March 1st 2014 to February 28th 2015, 103 patients underwent LT and the other 17 without prior KP died during the waiting period. In 103 patients undergoing LT, 58 patients received KP previously (Group A), and 45 only underwent primary LT (Group B). The nutritional status, liver function and LT-related short-term complications were analyzed. RESULTS Compared to Group B, patients in Group A had significantly increased time interval when undergoing LT (p < 0.05). Persistently, the bodyweight, albumin and hemoglobin in Group A were significantly increased compared to Group B (all, p < 0.0001). The bilirubin, ALT/AST and PELD score in Group A were all decreased compared to Group B (p < 0.05) prior to LT. The incidences of post-LT severe infection and hypoalbuminemia in Group A were significantly lower than those of Group B (p < 0.05). CONCLUSIONS KP improves the nutritional status, preserves liver function for patients who finally undergo LT, and decreases the incidence post-LT severe infection and hypoalbuminemia. Mental health can be improved in parents whose children underwent previous KP.

Abstract
PURPOSE The objective of this study was to determine the predictive index for prognosis in patients with biliary atresia (BA). METHODS A total of 71 patients were divided into two groups. Group A included 39 postoperative BA patients who survived for more than 5 years with normal liver function and did not present cirrhosis, and group B included 32 patients who died from liver failure within 1 year after surgery. The clinical data of the two study groups were compared, and liver pathology was evaluated using a scoring system. RESULTS The average age and weight were similar in the two groups (64.1 ± 16.8 days vs. 60.7 ± 19.3 days, p > 0.05; 4.9 ± 0.9 kg vs. 4.7 ± 0.8 kg, p > 0.05). There were no significant intergroup differences in preoperative total bilirubin (TB), direct bilirubin (DB), alanine transaminase, aspartate transaminase, and international normalized ratio. The preoperative levels of gamma-glutamyl transpeptidase (γ-GT) and albumin in group A were significantly higher than those in group B (γ-GT: 956.8 ± 503.8 IU/L vs. 620.2 ± 437.1 IU/L, p = 0.00; ALB: 40.8 ± 2.5 g/L vs. 36.8 ± 3.6 g/L, p = 0.04), whereas alkaline phosphatase was significantly lower in group A compared to group B (512.2 ± 224.6 IU/L vs. 631.7 ± 254.7 IU/L, p = 0.02). The postoperative TB and DB after 2 weeks of the Kasai procedure decreased significantly more in group A than in group B (TB: 53.9 vs. 21.4%, p = 0.00; DB: 51.0 vs. 22.7%, p = 0.00), whereas γ-GT increased significantly less in group A than in group B (48.3 vs. 142.1%, p = 0.00). Cystic structures were observed at the porta hepatis on ultrasound in more patients from group A (28.2 vs. 3.2%, p < 0.00). There was no significant difference in the total pathological score between the two groups (p = 0.38) whereas the score of bile plugs was significantly higher in group A (0.95 vs. 0.38, p = 0.03). CONCLUSION The cystic structures observed at the porta hepatis on ultrasound preoperatively and the rapid decrease in TB and DB within 2 weeks postoperatively predict good long-term prognosis, whereas a significant increase in γ-GT with a lower preoperative level predicts poor long-term prognosis. The development of bile plugs may be an indicator of favorable prognosis.

Abstract
PURPOSE OF REVIEW Biliary atresia is the most common indication for liver transplantation among children. In recent years, prospective, multi-centre collaboration has been underway with the aim of providing high-quality data on the natural history of the condition, prior to and following hepatic portoenterostomy. RECENT FINDINGS There is increasing evidence that specific histological findings, and age, at the time of portoenterostomy have relevance as prognostic indicators. Recent data suggest that the sub-type of biliary atresia, its co-existence with other anomalies and concurrent infection may also be important variables. This review provides a comprehensive summary of the histological predictors of outcome following portoenterostomy. Later age at portoenterostomy, advanced degree of hepatic fibrosis and co-existence with other congenital anomalies are strongly correlated with poor outcomes following portoenterostomy. There is increasing evidence to suggest that common serological indices and the presence or absence of cytomegalovirus (CMV) co-infection may have utility as early prognostic indicators.

Abstract
AIM OF THE STUDY To report the outcomes of children who underwent Sengstaken-Blakemore tube (SBT) insertion for life-threatening haemetemesis. METHODS Single institution retrospective review (1997-2012) of children managed with SBT insertion. Patient demographics, diagnosis and outcomes were noted. Data are expressed as median (range). MAIN RESULTS 19 children [10 male, age 1 (0.4-16) yr] were identified; 18 had gastro-oesophageal varices and 1 aorto-oesophageal fistula. Varices were secondary to: biliary atresia (n=8), portal vein thrombosis (n=5), alpha-1-anti-trypsin deficiency (n=1), cystic fibrosis (n=1), intrahepatic cholestasis (n=1), sclerosing cholangitis (n=1) and nodular hyperplasia with arterio-portal shunt (n=1). Three children deteriorated rapidly and did not survive to have post-SBT endoscopy. The child with an aortooesophageal fistula underwent aortic stent insertion and subsequently oesophageal replacement. Complications included gastric mucosal ulceration (n=3, 16%), pressure necrosis at lips and cheeks (n=6, 31%) and SBT dislodgment (n=1, 6%). Six (31%) children died. The remaining 13 have been followed up for 62 (2-165) months; five required liver transplantation, two underwent a mesocaval shunt procedure and 6 have completed endoscopic variceal obliteration and are under surveillance. CONCLUSIONS SBT can be an effective, albeit temporary, life-saving manoeuvre in children with catastrophic haematemesis.

Abstract
OBJECTIVES Biliary atresia (BA) is the most common liver disease leading to liver transplantation (LT) during childhood. The optimal timing of listing and LT for children with failed portoenterostomy (PE) is not clear. The aim of our study was to determine the optimal timing of LT for children with BA and failed PE by using a Markov model simulation analysis. METHODS A Markov model was constructed presenting the progression of the severity of liver status for patients with BA who underwent PE before 60 days old. Three treatment strategies were compared: LT for moderate liver disease (MLD), LT for severe liver disease (SLD), and no LT, and 10,000 patients were simulated in each strategy. Health states were defined as LT, early repeat LT (≤30 days after LT), late repeat LT (>30 days after LT), status post-LT (period after first LT), and death. RESULTS For patients with an available liver for transplantation (living donors), LT at MLD was associated with an increase of 17.4% additional expected life-years (LY) as compared with LT at SLD. Patient survival rates after 10 years were 84.7% and 75.5% in the MLD and SLD strategies, respectively. For the patients with no LT, the survival rate after 10 years was 48.1%. When the probability of deceased donor LT was lower than 50% from time of listing at 3 months, there was no increase in expected LY of MLD strategy. "No LT" resulted in approximately 60% reduction of expected LY compared with LT for patients with SLD. CONCLUSIONS Our model suggests that early listing and transplantation is beneficial in patients with an available liver for transplantation. For patients in whom the probability for LT is low, there appears to be no advantage to early listing. A validation of the present model in a "real" cohort of patients with BA is needed.

Abstract
A newborn female was transferred to our hospital presenting with severe respiratory distress. She underwent tracheal intubation and nasogastric tubing. Investigations revealed a congenital extrahepatic portosystemic shunt (CEPS) type 1, biliary atresia, heterotaxia, polysplenia, malrotation and a double aortic arch (DAA). She underwent the Kasai portoenterostomy and the Ladd procedure when she was 29 days old. On postoperative day 20, she developed sudden hematemesis with bright red blood. Endoscopy showed massive bleeding from an esophageal ulcer, and endoscopic therapy was performed successfully. During left thoracotomy, an aortoesophageal fistula (AEF) was detected and repaired by direct suturing. The postoperative course was uneventful. CEPS type 1 is commonly associated with other congenital malformations; however, there have been no previous reports of an association between CEPS and DAA. Nasogastric tube insertion in a patient with DAA can result in catastrophic AEF. The treatment strategy should be carefully considered in patients with CEPS type 1 and multiple congenital fetal anomalies.

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.
