The duodenal tube test is more specific than hepatobiliary scintigraphy for identifying bile excretion in the differential diagnosis of biliary atresia. Surg Today 2020; 50:1232-1239.

Abstract
PURPOSE Confirmation of bile excretion into the gastrointestinal tract is important to exclude biliary atresia (BA). We compared the duodenal tube test (DTT) with hepatobiliary scintigraphy (HS) for their efficiency in detecting bile secretion. METHODS The subjects of this retrospective study were 47 infants who underwent both DTT and HS to diagnose or exclude BA between January 2000 and March 2018. RESULTS BA was diagnosed in 32 of the 47 patients, and 7 of the remaining 15 non-BA patients underwent intraoperative cholangiography. Among the various DTT parameters, the total bile acid in duodenal fluid (DF-TBA)/serum (S) gamma-glutamyl transferase (γGTP) ratio was found to be the most specific for BA, with sensitivity and specificity of 98.0-100%, respectively. One BA patient in whom cut off values were not met was a premature infant. The sensitivity and specificity of HS were 100-56.3%, respectively. The diagnostic accuracy of the DF-TBA/S-γGTP parameter was higher than that of HS (98.6% vs. 85.1%, respectively). CONCLUSIONS The DTT could be more a specific method than HS to detect bile excretion. Thus, the DTT should be incorporated into the multidisciplinary diagnostic approach for the differential diagnosis of BA to prevent unnecessary intraoperative cholangiography in patients who do not have BA.

Abstract
AIM OF STUDY The diagnosis of biliary atresia (BA) remains challenging and delay can lead to significant morbidity with time to surgery a key factor in determining outcome. Prematurity may impact on outcome potentially delaying diagnosis. We sought to assess whether the premature BA infants (PBA) have a delayed time to surgery and as such, worse outcomes? METHODS Review of a single-centre prospectively maintained database. Prematurity was defined as delivery < 37/40 gestation. PBA was compared with date-matched term biliary atresia controls on a 2:1 basis. Primary outcomes were clearance of jaundice (< 20 μmol/L) and native liver survival. A retrospective assessment of liver fibrosis was made on biopsies at diagnosis and at Kasai portoenterostomy (KPE) in both premature and term cohorts. Data are quoted as median (range) unless indicated. A P value of ≤ 0.05 was considered statistically significant. RESULTS 21 (female n = 14, 67%) premature infants with BA were treated in the period Jan. 1988-Dec. 2016 and compared with 41 contemporaneous term BA controls. Median gestation was 33 (29-36) weeks and birth weight 1930 (948-4230)g. Twin pregnancy (n = 10) was the leading cause for prematurity and significantly higher than the controls (48 vs. 0%; P < 0.0001). Maternal co-morbidity was high (n = 10, 48%) including pre-eclampsia (19%) and diabetes (14%). Liver biopsy was performed in 19 (90%) patients (all diagnostic) at a median of 57 (4-266) days. Delayed diagnosis (> 50 days) was seen in n = 13 but not associated with parenteral nutrition use (46 vs. 33%, P = 0.59) or phototherapy (50 vs. 83%, P = 0.19). Both BASM (33 vs. 7.5%; P = 0.01) and duodenal atresia (19 vs. 0%; P = 0.01) were seen more frequently in the PBA cohort. Mean fibrosis scores (Ishak) from diagnostic biopsies were lower in the premature group than the control group (2.71 vs. 3.53, P = 0.043) indicating less fibrosis but this equalized by time of subsequent KPE (P = 0.17). Primary surgery was Kasai portoenterostomy (n = 20) at an older median age than controls (65 vs. 56 days; P = 0.06). Liver transplantation was the primary procedure in one late-presenting child. There was an increased but non-significant clearance of jaundice in the PBA group [n = 12/20 (60%) vs 20/41 (48%); P = 0.23] post-KPE. Native liver survival and true survival were not different (P = 0.58 and 0.23). CONCLUSIONS PBA infants have similar outcomes to term infants, despite delayed diagnosis and higher frequency of the syndromic form. The high incidence of discordant twins supports the theory that epigenetic modifications could contribute to the pathogenesis of BA. LEVEL OF EVIDENCE IIIc Retrospective Matched Cohort Study.

Abstract
OBJECTIVES Biliary atresia (BA) occurs in 0.54 of 10.000 of overall live births in the Netherlands. BA has an unfavorable prognosis: <40% of patients are cleared of jaundice after Kasai portoenterostomy (KPE), 4-year transplant-free survival rate is 46% and the 4-year survival rate is ∼75%. Little is known on difficulties in diagnosis and the outcome of BA in preterm infants. We aimed to analyze the incidence and outcome of BA in preterm infants in the Netherlands. METHODS Retrospective study including Dutch preterm infants treated for BA. Parameters included gestational age, congenital anomalies, age at KPE, days between first symptoms, and KPE and referral interval (first hospital to KPE). Outcome parameters were clearance of jaundice (COJ) and (transplant-free) survival. Data are presented as medians (ranges). RESULTS Included 28 preterm infants (13 boys/15 girls) between March 1988 and December 2015. The incidence of BA was 1.06 of 10.000 preterm live births. Gestational age was 34.8 (27.3-36.9) weeks. Congenital anomalies were present in 11 of 28 (39%) infants. Time between first symptoms and KPE was 57 (9-138) days. Referral interval was 28 (8-86) days. Age at KPE was 70 (35-145) days. COJ was achieved in 23% of cases. Four-year transplant-free survival rate was 21%. Four-year overall survival was 61%. CONCLUSIONS BA has a higher incidence in the preterm population compared to the overall BA population. The outcome of BA in preterm infants is poor, regarding COJ and (transplant-free) survival. We speculate that timely recognition of BA-related signs and symptoms in preterm infants will improve prognosis.

Abstract
The age threshold at the time of Kasai hepatic portoenterostomy associated with a prognosis of biliary atresia (BA) is becoming clearer as 10-year native liver survival data become more frequent in the recent literature, whereas the age at diagnosis has not dramatically decreased during the last 3 decades. A stool color card screening implemented in 1994 in Japan is now expanding worldwide. However, the contribution of this modality will probably be limited because of the nature of this disease, for example, 'progressive obliterative cholangiopathy'. A cholic stool was actually observed only in 50% before diagnosis according to the Japanese BA Registry data. Thus, color card screening does not appear to be instrumental in detecting patients with BA early enough before 1 month of age. A highly sensitive, adequately specific, noninvasive and quantitative method may be expensive, but the overall cost would be lower than that of liver transplant.
