RESUMO
BACKGROUND: Robotic-assisted Kasai portoenterostomy (RAKPE) has been used to treat biliary atresia (BA). This study aimed to compare the efficacy of RAKPE and open Kasai portoenterostomy (OKPE) for BA. METHODS: Thirty-one children with type III BA who underwent surgical treatment in two centers from January 2022 to December 2023 were retrospectively collected. According to the operative techniques, the participants were divided into the RAKPE group (13 cases) and the OKPE group (18 cases). The operative time, jaundice clearance (JC) rate, and incidence of cholangitis were analyzed. RESULTS: The operative time in the RAKPE group (204.3 ± 19.9 min) was significantly longer than that in the OKPE group (186.2 ± 22.2 min), P < 0.05. However, the blood loss (8.1 ± 2.5 ml) in the RAKPE group was significantly decreased compared with the OKPE group (13.6 ± 4.8 ml), and 15.4% patient need blood transfusion in RAKEP group was litter than that 55.6% in the OKPE group, P < 0.05. The time to oral feeding (2.8 ± 0.4 days vs. 4.3 ± 0.7 days) and the time to pass ICG-positive stools (3.6 ± 0.6 days vs. 4.7 ± 0.9 days) in the RAKPE group were significantly shorter than those in the OKPE group, P < 0.05. No significant differences were observed in the bile excretion rate, hospital stay time, and JC rate. The incidence of cholangitis in the RAKPE group was significantly lower than that in the OKPE group during short follow-up. CONCLUSION: RAKPE may be associated with lower intraoperative blood loss, decrease need for postoperative transfusions and decreased rate of postoperative cholangitis compared to OKPE. LEVEL OF EVIDENCE: III.
RESUMO
PURPOSE: Stool color (SC) for monitoring prednisolone use in biliary atresia (BA) patients after laparoscopic portoenterostomy (LPE) was reviewed. METHODS: Subjects were 47 post-LPE BA patients given a reducing dose course of intravenous prednisolone. The course started at 4 mg/kg/day and gradually reduced, ultimately reaching a final total dose (TD) of 31.5 mg/kg. Normal SC indicated a course could progress until finished and was repeated until jaundice clearance (JC) was achieved. Abnormal SC persisting for two consecutive courses was the absolute indication for redo or liver transplantation (LTx). RESULTS: JC was achieved in 38/47 (80.9%) LPE cases and 4/6 redos to give an overall JC rate (JCR) of 42/47 (89.4%). Outcomes after one course (n = 5; JCR: 80.0%; median TD: 30.0 mg/kg, interquartile range [IQR: 26.0-31.5]), two courses (n = 10; JCR: 90.0%; median TD: 62.5 mg/kg [IQR: 60.8-66.0]), three courses (n = 13; JCR: 92.3%; median TD: 90.0 mg/kg [IQR: 86.0-90.0]), four courses (n = 10; JCR: 80.0%; median TD: 120.0 mg/kg [IQR: 116.7-123.3]), five courses (n = 7; JCR: 100%; median TD: 156.0 mg/kg [IQR: 154.3-157.5]), six courses (n = 1; JCR: 100%; TD: 189.0 mg/kg), ten courses (n = 1; JCR: 100%; TD: 308 mg/kg). CONCLUSION: Indications for repeat prednisolone and timing of redo/LTx based on SC monitoring appeared effective based on high JCR and successful redo/LTx. LEVELS OF EVIDENCE: III.

Objectives: To explore the outcomes and related factors in children without cholangitis after Kasai portoenterostomy (KPE). Methods: We retrospectively analyzed the data of infants with type III BA who underwent KPE from June 2016 to December 2021. We compared and analyzed the difference in native liver survival (NLS) rates in different types of cholangitis. We also investigated the relationship between the absence of cholangitis and the effect of early bile drainage (EBD) as well as the related factors affecting EBD efficacy. Results: A total of 145 children were included in this study. Among these children, 82 (56.6%, 82/145) had cholangitis, including 40 (48.8%, 40/82) with early cholangitis and 33 (40.2%, 33/82) with recurrent cholangitis. The median follow-up period was 29 months (range, 2-75 months). The NLS rates were 67.6%, 51.7%, 45.5% and 43.4% at 6 months, 1 year, 2 years and 5 years following KPE, while the NLS rates for infants without cholangitis after KPE were 68.3%, 50.8%, 46.0% and 46.0%, respectively. Higher gamma-glutamyl transferase (γ- GT) and total bile acid (TBA) before KPE were risk factors for cholangitis (P < 0.05). The NLS rate in recurrent cholangitis was significantly lower than that in occasional cholangitis (P < 0.01). Compared with the EBD-poor group, the NLS rate in the EBD-good group of infants was significantly increased (P < 0.001). EBD was significantly correlated with the occurrence and frequency of cholangitis (P < 0.05). Conclusions: Recurrent cholangitis was an important factor affecting NLS. For children without cholangitis after KPE, early bile drainage was better, and the NLS was longer.
RESUMO
Objective: To investigate the clinical features and prognosis of biliary atresia (BA) with normal or minimally elevated gamma-glutamyl transpeptidase (GGT). Methods: The clinical data of patients with BA in our hospital between 2012 and 2017 were retrospectively studied. The patients were divided into a low-GGT group (GGT ≤ 300 IU/L) and a high-GGT group (GGT > 300 IU/L) according to the preoperative GGT level. The perioperative clinical parameters, the postoperative jaundice clearance within 6 months, and the 2-year native liver survival were compared among the groups. Results: A total of 1,998 children were included in this study, namely, 496 in the low-GGT group and 1,502 in the high-GGT group. The ages and weights at the surgery in the low-GGT group were significantly lower than those in the high-GGT group (64.71 ± 21.35 vs. 68.64 ± 22.42 days, P = 0.001; 4.67 ± 1.03 vs. 4.89 ± 0.98 kg, P < 0.001). The levels of serum ALP, ALT, and AST in the low-GGT group were significantly higher than those in the high-GGT group before and 2 weeks after the surgery (ALP: 647.52 ± 244.10 vs. 594.14 ± 228.33 U/L, P < 0.001; ALT: 119.62 ± 97.14 vs. 96.01 ± 66.28 U/L, P < 0.001; AST: 218.00 ± 173.82 vs. 160.71 ± 96.32 U/L; P < 0.001). The INR of the low-GGT group was higher than that of the high-GGT group (1.05 ± 0.34 vs. 0.98 ± 0.20, P < 0.001), while FIB was lower than the high-GGT group (2.54 ± 0.67 vs. 2.73 ± 1.44 g/L; P = 0.006). The decreasing amplitude of TB and DB within 2 weeks after surgery in the low-GGT group was smaller than those in the high-GGT group (TB: 51.62 ± 71.22 vs. 61.67 ± 53.99 µmol/L, P = 0.003; DB: 33.22 ± 35.57 vs. 40.20 ± 35.93 µmol/L, P < 0.001). The jaundice clearance rate in the low-GGT group was significantly lower than that in the high-GGT group at 1, 3, and 6 months after surgery (17.70 vs. 26.05%; 35.17 vs. 48.58%; 38.62 vs. 54.64%, P < 0.001). In addition, the 2-year native liver survival rate in the low-GGT group was significantly lower than that of the high-GGT group (52.5 vs. 66.3%, P < 0.001 HR 1.80, 95% CI 1.38-2.33). Conclusion: Compared to patients with high GGT, patients with normal or minimally elevated pre-operative GGT in BA were found to have poorer pre-operative liver function parameters, and post-operatively had lower jaundice clearance rates and worse 2-year native liver survival. This suggests a lower GGT at presentation in biliary atresia could be a sign of more severe liver injury.
RESUMO
PURPOSE: This study aimed to evaluate the efficacy of adding a spur valve to laparoscopic portoenterostomy for patients with biliary atresia. METHODS: We retrospectively reviewed the records of all patients diagnosed with biliary atresia (BA) who underwent laparoscopic portoenterostomy (Lap-PE) between 2013 and 2021. The patients were divided into two groups: Lap-PE with a spur valve (spur group) and without it (control group). Perioperative management was the same in both groups. We compared patient backgrounds and clinical outcomes, including jaundice clearance and the number of postoperative cholangitis episodes. RESULTS: Of 63 patients reviewed, 16 received a spur valve. There were no statistically significant differences in the patient backgrounds between the groups. All patients in the spur group achieved jaundice clearance. The number of postoperative cholangitis episodes one year after surgery was significantly lower in the spur group than in the control group (1 [0-3] vs. 3 [0-9], p = 0.04). The jaundice-free survival rate with the native liver at one year after surgery was significantly higher in the spur group (100% vs. 53%, p = 0.01). CONCLUSIONS: Adding a spur valve during Lap-PE significantly lowered the number of cholangitis episodes 1 year after surgery.

Background: Biliary atresia (BA) is the most common cholestatic liver disease in neonates. Herein, we aimed at characterizing the gut microbiota and fecal bile acid profiles of BA patients, defining the correlations between them, and evaluating the relationship between the clinical pathogenesis and changes in the gut microbiota and bile acid profiles. Methods: A total of 84 fecal samples from BA patients (n = 46) and matched healthy controls (HCs, n = 38) were subjected to sequencing by 16S rRNA gene amplification, and fecal bile acid were analyzed by targeted metabolomics. Findings: Compared with the controls, a structural separation of the intestinal flora of BA patients was uncovered, which was accompanied by changes in the composition of fecal bile acids. In the BA group, Actinobacillus, Monoglobus, and Agathobacter were enriched in patients without cholangitis (p < 0.05). Selenomonadaceae and Megamonas were more abundant in patients without recurrent cholangitis episodes (p < 0.05), while Lachnospiraceae and Ruminococcaceae were enriched in patients with multiple recurrences of cholangitis (p < 0.05). Postoperative jaundice clearance was associated with Campylobacter and Rikenellaceae (p < 0.05), and tauroursodeoxycholic acid was associated with jaundice clearance (p < 0.001). Conclusion: BA patients are characterized by different compositions of gut microbiota and bile acids, and their interaction is involved in the process of liver damage in BA, which may be closely related to the occurrence of postoperative cholangitis and jaundice clearance.

PURPOSE: Open portoenterostomy (PE) for biliary atresia (BA) is currently more extended (EP) than the original (OP). Typical OP techniques, shallow transection of the biliary remnant and shallow suturing, both lost in EP, were revived as a modified procedure (MP). Postoperative outcomes of EP and MP were compared. METHODS: Subjects were 55 consecutive BA patients treated by EP (n = 18) or MP (n = 37) at a single center between 2004 and 2021. RESULTS: Mean follow-up duration was: MP: 15.5 years (range 0.1-12.3 years) and EP: 15.5 years (range 0.38-17.1 years). The ratio of jaundice free (JF; total bilirubin ≤ 1.2 mg/dL) subjects was significantly higher in MP (78.4%) versus EP (50%); p > 0.05, the incidence of bile lakes at the porta hepatis was significantly higher in MP (7/37: 18.9%) versus EP (0/18: 0%); p > 0.05, and Kaplan-Meier analysis showed JF survival with the native liver (JF + SNL) was significantly better in MP (26/37: 70.2%) versus EP (4/18: 22.2%); p > 0.05. All other criteria were similar. Of note, time taken to become JF and the incidence of cholangitis were not significantly different. CONCLUSIONS: Shallow transection and shallow suturing would appear to influence postoperative outcome. The etiology of bile lake formation in MP requires urgent confirmation.

Objective: The etiology of biliary atresia is unclear, but viral infection has been implicated. The aim of the current meta-analysis was to investigate relationships between cytomegalovirus (CMV) and the prognosis of biliary atresia. Methods: PubMed, Embase, the Cochrane Library, the China National Knowledge Infrastructure database, and Wanfang Data electronic databases were searched for eligible studies. Each relevant text was thoroughly reviewed and examined, including related papers in their reference lists. Results: A total of nine studies including 784 patients were included in the analysis. Biliary atresia patients with CMV exhibited significantly lower jaundice clearance (odds ratio: 0.46, p < 0.0001; I 2 = 15%, p = 0.31). There were no significant differences in the rates of cholangitis or native liver survival. CMV-pp65-positive biliary atresia patients had a significantly lower rate of jaundice clearance (odds ratio: 5.87, p = 0.003; I 2 = 0%, p = 0.71) and a significantly higher rate of cholangitis (odds ratio: 0.21, p = 0.01; I 2 = 0%, p = 0.43) than CMV antibody-positive biliary atresia patients. Conclusion: Biliary atresia patients who were also infected with CMV had a poorer prognosis, particularly with respect to jaundice clearance. CMV status may influence the prognosis of biliary atresia. Clinicians should be able to routinely identify the subset of biliary atresia patients who are also CMV-positive, in order to improve native liver survival.
RESUMO
PURPOSE: Portoenterostomy (PE) is the standard treatment for biliary atresia (BA). However, micro-bile ducts are difficult to identify with surgical loupes and dissect systematically. We report the effects of our attempts to dissect hilar tissue using a surgical microscope. METHODS: Microscopy-assisted portoenterostomy (MAPE) was initiated in 2014. Patients born between 2000 and 2013 who underwent PE until day 70 without a surgical microscope for BA were gathered as historical control. MAPE in re-do PE cases (Re-MAPE) was evaluated in the same manner. RESULTS: Ten patients underwent MAPE for BA during the study period. 17 patients in the conventional PE group were gathered. In the MAPE group, the jaundice clearance rate was 80%, compared with 53% in the conventional PE group. Re-MAPE was performed in four patients, who had a jaundice clearance rate of 75%, essentially identical to the rate with initial MAPE. At age 4 years, the native liver survival rate was 58% in the MAPE group and 38% in the conventional PE group. The native liver survival rate in the Re-MAPE group was 75%. CONCLUSION: MAPE is useful for sharing the surgical field during open PE in patients with BA. It may improve the rate of jaundice clearance.

Purpose: To analyze the influence of perioperative complications in the management of biliary atresia (BA). Methods: A retrospective study was performed using a total of 422 BA patients who underwent Kasai portoenterostomy (KPE) in a single institution between February 2016 and May 2017. Data on patients' clinical characteristics, laboratory examinations, perioperative complications, and outcomes were collected. Unpaired two-tailed t-test and χ2 test were employed for the comparison between BA patients with and without perioperative complications. Cox regression analysis was used to screen the risk factors for 2-years NLS in BA, and their influence on the 2-years NLS was analyzed using Kaplan-Meier survival analysis as well as the log-rank test. Results: The incidence of perioperative complications, 6-months jaundice clearance (JC) and 2-years native liver survival (NLS) rate were 60.4, 59.5, and 56.6%, respectively. Patients with perioperative complications had lower serum albumin (ALB) level, but higher aspartate aminotransferase-to-platelet ratio index (APRI) and international normalized ratio (INR) levels when compared with those without perioperative complications (ALB, P < 0.05; APRI, P < 0.01; INR, P < 0.05). Moreover, perioperative complications were correlated with glucocorticoid administration (P = 0.002). Univariate Cox regression analysis showed no relationship between perioperative complications and 2-years NLS (P > 0.05). However, multivariate Cox regression analysis indicated 6-months JC was an independent protective factor for 2-years NLS [P < 0.0001, hazard ratio (HR) = 0.074, 95% confidence interval = 0.05-0.11], and concordance index of this prediction model including age, weight, APRI, glucocorticoid, and 6-months JC was 0.811. Conclusion: Although perioperative complication is common during and after KPE, it had no influence on the prognosis of BA. However, assessment of the serum level of total bilirubin after KPE may serve as an important predictor for the outcome in BA.
RESUMO
PURPOSE: Cholangitis after Kasai procedure has been previously shown to be related to poor prognosis in Biliary Atresia (BA). To investigate the risk factors and clinical outcomes of cholangitis, we did a retrospective study in post-Kasai BA patients. METHODS: Two-year follow-up data of 180 type-III BA patients after Kasai procedure in 2016 in our hospital were analyzed, including 119 cholangitis patients (66.11%). Among the cholangitis group, patients were further divided into early vs late cholangitis and single vs recurrent cholangitis groups. Liver pathology, liver function, cholangitis occurrence and frequency, jaundice clearance, and survival rates were examined. RESULTS: Higher gamma-glutamyl transferase level before Kasai is a risk factor for cholangitis (pâ¯=â¯0.0393). Older age and higher liver fibrosis score at Kasai are risk factors for recurrent cholangitis (pâ¯<â¯0.05). Shorter prophylactic intravenous antibiotics usage may contribute to early cholangitis, which may lead to higher cholangitis frequency (pâ¯<â¯0.0001). Recurrent cholangitis is associated with earlier cholangitis onsets (pâ¯<â¯0.0001). Cholangitis patients have a relatively delayed jaundice clearance, while early and recurrent cholangitis may contribute to lower overall survival. CONCLUSIONS: Personalized treatment considering risk factors in individual BA patients is needed to prevent cholangitis, especially early onsets, and to improve postoperative outcomes. LEVEL OF EVIDENCE: III.

OBJECTIVE: To explore the preoperative nutrition status in patients with biliary atresia (BA) and its effect on the cholangitis of Kasai portoenterostomy (KPE). METHODS: 106 patients who had been diagnosed with BA type III and were undergoing KPE were divided into two groups according to the score obtained using STRONGkids. Preoperative and postoperative data were collected to compare general characteristics and postoperative outcomes between the different groups. RESULTS: Forty-nine (46.2%) patients were at moderate nutritional risk (MNR) and fifty-seven (53.8%) patients were at high nutritional risk (HNR) preoperatively. The MNR group had shorter postoperative hospitalization times than the HNR group (P = 0.023). The initial postoperative cholangitis occurred later (P = 0.002) and the incidence of early cholangitis was lower (P = 0.029) in patients at MNR than in those at HNR. The ratio of jaundice clearance (P = 0.02) and 2-year native liver survival (P = 0.0109) were significantly higher in MNR group than in HNR group. CONCLUSIONS: Patients with BA presented the greatest nutritional deficiencies and patients at HNR are more vulnerable to the early cholangitis and the rate of jaundice clearance is lower than those at MNR. The occurrence of initial postoperative cholangitis in MNR group was later than in HNR group.

BACKGROUND: The purpose of this study was to assess the clinical outcome of patients treated with the current technique of Kasai procedure compared with that of those treated with previous procedures. METHODS: We retrospectively assessed the outcomes of 256 patients with biliary atresia who underwent Kasai portoenterostomy at our hospital between 1972 and 2014. Patients were divided into four groups: group 1 (1972-1981, double Roux-en Y, n=91), group 2 (1982-1991, Suruga II, n=80), group 3 (1992-2000, double-valve Roux-en Y, n=46), and group 4 (2001-2014, total removal of the extrahepatic biliary remnants at hepatic capsule and Roux-en Y reconstruction with a spur valve, n=39). Clinical outcomes were compared between the four groups. RESULTS: In groups 1, 2, 3, and 4, the rate of jaundice clearance was 65.9%, 77.5%, 63.0%, and 87.2%, respectively; incidence of early cholangitis was 60.4%, 53.8%, 37.0%, and 23.1%, respectively; requirement for redo Kasai surgery was 15.4%, 37.5%, 17.4%, and 5.1%, respectively; 10-year native liver survival rate was 53.8%, 60.1%, 44.1%, and 73.7%, respectively; and 10-year overall survival rate was 55.0%, 72.3%, 86.7%, and 97.3%, respectively. CONCLUSION: The standardized Kasai procedure was associated with favorable outcomes. Long-term outcomes remain to be evaluated. LEVEL OF EVIDENCE: Case-control/treatment study, level III.

AIMS: In 1955, Professor Morio Kasai first performed a hepatic portoenterostomy. Since then, the procedure has changed the lives of children with biliary atresia (BA). We report our initial experience in performing "extended" Kasai portoenterostomy (KPE), a modification of the original procedure. MATERIALS AND METHODS: Since 2013, we have used the technique of "extended KPE" and prospectively recorded data on all children undergoing this operation. Data on demographics, clinical features, liver function tests, and perioperative cholangiogram findings were collected. Outcome of KPE was measured by Jaundice Disappearance Rate (JDR) and Native Liver Survival Rate (NLSR). We present our preliminary results from a 30-month period (February 2013 to May 2015). RESULTS: Thirty-one children underwent KPE during this period (19 males) and only 1 child had biliary atresia splenic malformation (BASM). The mean age at KPE was 73 ± 24 days. Five (16.1%) children were more than 90 days old at the time of KPE. Fourteen children cleared jaundice (JDR 45.2%). Eleven (35.5%) children developed episodes of cholangitis, of whom 8 had early cholangitis (within 3 months of the operation). The proportion of children who survived with their own liver 6 months after KPE (NLSR) was 84.2%. Of those children older than 90 days, 2 cleared jaundice and have survived with their native livers for more than 16 months. CONCLUSION: In our preliminary report of 31 children, we conclude that the extended KPE leads to increased jaundice clearance and improved NLSR in children with BA.
RESUMO
BACKGROUND/OBJECTIVES: Adjuvant steroid therapy has become popular in the postoperative management of biliary atresia. However, the benefits of steroid therapy are still not clear. We performed a systematic review and meta-analysis to determine the effect of steroids on bile drainage posthepatoportoenterostomy. METHODS: Studies published from 1968 to 2014 were searched from MEDLINE, EMBASE, Google scholar and Cochrane databases. A meta-analysis of randomized controlled trials (RCT) and observational studies comparing bile drainage between steroid and nonsteroid therapies posthepatoportoenterostomy was performed. RESULTS: Seven studies (2 RCTs and 5 observational studies) were included, comprising 259 cases of nonsteroid and 228 cases of steroid therapies. There was no statistical improvement in jaundice clearance in the steroid group [pooled odds ratio (OR)=1.51; 95% confidence interval (CI) 0.95-2.41; P=0.08; I(2)=30%]. Among 7 studies, 4 studies applied similar moderate high-dose steroid regimens (prednisolone 4-5mg/kg/day for 1-2 weeks followed by weeks of tapering dosage). However, these moderate high-dose regimens demonstrated improved jaundice clearance at 6 months posthepatoportoenterostomy (pooled OR=1.59; 95% CI 1.03-2.45; P=0.04; I(2)=0%). A subgroup analysis also showed that the effect of those moderate high-dose steroids was more pronounced in infants operated on by 70 days of age (pooled OR=1.86; 95% CI 1.08-3.22; P=0.03; I(2)=0%). CONCLUSION: Moderate high-dose steroid therapy improves jaundice clearance, especially for infants who undergo hepatoportoenterostomy by 70 days of age. However, more RCTs with longer follow-up are necessary to demonstrate the effect of steroids on the long-term outcomes of biliary atresia.
