ABSTRACT
BACKGROUND: Matrix metalloproteinase-7 (MMP-7) is associated with biliary injury. This study aimed to evaluate the relationships of serum MMP-7 with clinical characteristics in choledochal cysts (CDC) children. METHODS: Between June 2020 and July 2022, we conducted a prospective study of CDCs who underwent one-stage definitive operation at our center. Serum MMP-7 was measured using an enzyme-linked immunosorbent assay. We evaluated the relationships between serum MMP-7 and age, laboratory tests, imaging examinations, liver fibrosis, MMP-7 expression, and perforation. RESULTS: A total of 328 CDCs were enrolled in the study, with a median serum MMP-7 of 7.67 ng/mL. Higher serum MMP-7 was correlated with younger age at diagnosis (p < 0.001), larger cyst sizes (p < 0.001), higher liver fibrosis stages (p < 0.001), and higher incidence of perforation (p < 0.01). Liver MMP-7 was mainly expressed in intrahepatic and extrahepatic biliary epithelial cells. The area under the receiver operating characteristic curve (AUROC) was 0.630 (p < 0.001) for serum MMP-7 in predicting perforation. When serum MMP-7 was combined with γ-glutamyl transferase (GGT), the AUROC increased to 0.706 (p < 0.001). CONCLUSIONS: Serum MMP-7 was associated with biliary obstruction in CDCs. Patients with high serum MMP-7 were more likely to have severe liver damage and biliary injury, with higher incidences of liver fibrosis and perforation.

Purpose: During the second stage surgery for anorectal malformations (ARM), patients whose distal intestine of the colostomy is particularly short underwent laparoscopic-assisted distal colon excision and proximal colon pull-through anorectoplasty (PCPARP). This study aimed to discuss the outcomes of PCPARP after colostomy in patients with ARM. Methods: This is a single-center propensity score-matched (PSM) study which was retrospectively initiated patients with intermediate- or high-type ARM who underwent laparoscopic surgery from June 2007 to December 2018. These patients were divided into PCPARP group and conventional laparoscopic-assisted anorectoplasty (LAARP) group according to specific surgical methods. The general data, surgical data, postoperative complications, and functional results were evaluated. Results: In total, 216 patients were included in this study: 190 (88.0%) undergoing LAARP approach and 26 (12.0%) undergoing PCPARP approach. After PSM, two well-balanced groups of 26 patients were analyzed and showed the postoperative complications (P = 0.126) and bowel function (P = 0.809) were similiar between the two groups. Conclusions: The curative effect of PCPARP after colostomy is similar to that of classic LAARP surgery, which can be used for ARM patients with a very short and abnormal distal intestine of the stoma.
ABSTRACT
BACKGROUND AND OBJECTIVE: Neuromuscular blocking agents are routinely used in laparoscopic surgery to optimize operative conditions. We compared the effect of a deep and moderate neuromuscular blockade (NMB) on surgical conditions and postoperative outcomes in children undergoing major laparoscopic surgery. METHODS: Sixty children aged 2-14 years scheduled to undergo major laparoscopic surgery were randomly allocated to deep (post-tetanic count 1-2 twitches) or moderate (train-of-four 1-2 twitches) NMB groups. The anesthesia was maintained with propofol and remifentanil, and the NMB was maintained with a rocuronium continuous infusion. At the end of the operation, the NMB were antagonized with sugammadex. The intra-abdominal pressure, airway pressure, Leiden Surgical Rating Scale, intraoperative hemodynamics, drug usages, duration of surgery, postoperative recovery time, pain, and complications were compared between the groups. RESULTS: The maximum and mean intra-abdominal pressure, the peak inspiratory pressure, and mean airway pressure were significantly lower in the deep NMB group than in the moderate NMB group (p < 0.001). The Leiden Surgical Rating Scale and the dosage of rocuronium were significantly higher in the deep NMB group than the moderate NMB group (p < 0.001). The intraoperative hemodynamics, duration of surgery, post-operative recovery time, pain, and the incidence rate of complications were not significantly different between the groups (p > 0.05). CONCLUSIONS: A deep NMB provided better operative conditions and similar recovery profiles compared with a moderate NMB as reversed with sugammadex in children undergoing major laparoscopic surgery.

Due to the controversy on the feasibility of laparoscopic-assisted anorectoplasty (LAARP) for the treatment of the anorectal malformation (ARM) with rectobulbar fistula (RBF), this study aimed to compare the outcomes of LAARP and posterior sagittal anorectoplasty (PSARP) for ARM with RBF. Demographic data, postoperative complications, and bowel function of RBF patients who underwent LAARP and PSARP at 2 medical centers from 2016-2018 were retrospectively reviewed. Eighty-eight children with RBF were enrolled, including 43 in the LAARP group and 45 in the PSARP group. There were no significant differences in the sacral ratio (P = .222) or sacral agenesis (P = .374). Thirty-seven and 38 patients in the LAARP and PSARP groups were followed up for a median of 4.14 years. The postoperative complications were comparable between the groups (P = .624), with no cases of urethral diverticulum. The urination of all cases was normal and no evidence of cyst formation was found on MCU or MRI during the follow-up period. The incidence of rectal prolapse was similar between the 2 groups (9.3% vs 17.8%, P = .247). The groups had equivalent Bowel Function Score (15.29 ± 2.36 vs 15.58 ± 2.88, P = .645), but the LAARP group had better voluntary bowel movement (94.6% vs 84.2%, P = .148) by Krickenbeck classification. The intermediate-term outcomes of LAARP show that the urethral diverticulum was rare by the intraluminal incision of the fistular and the bowel function was comparable to that of PSARP in ARM with rectobulbar fistula. However, LAARP was associated with smaller perineal wounds.

Introduction: Inflammation is closely associated with tumor development and patient prognosis. The objective of this study is to assess the prognostic value of the preoperative inflammatory indexes in pediatric hepatoblastoma patients who receive neoadjuvant chemotherapy. Methods: A retrospective analysis was performed on clinical and pathological data of 199 hepatoblastoma patients who underwent hepatectomy with preoperative neoadjuvant chemotherapy from January 2015 to June 2020. The receiver operating characteristic curve was used to evaluate the prognostic value of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune-inflammation index (SII), and systemic inflammation response index (SIRI) in predicting OS and EFS. Patients were grouped based on optimal cutoff values of preoperative inflammatory indexes. Survival rates were calculated using the Kaplan-Meier method, and survival outcomes were compared between groups using the log-rank test. Univariate and multivariate Cox proportional hazards regression models were used to identify independent prognostic factors, and a nomogram was constructed using R software to predict the probability of OS. Results: The receiver operating characteristic curve showed prognostic value for OS, not EFS, in preoperative inflammatory indexes. Patients were categorized into low/high groups: SII ≤ 266.70/higher, NLR ≤ 1.24/higher, PLR ≤ 85.25/higher, and SIRI ≤ 0.72/higher. High NLR, PLR, SII, and SIRI groups had significantly lower 5-year OS than their low counterparts (all p-value < 0.05). The Cox analysis identified four independent prognostic factors: SIRI (HR=2.997, 95% CI: 1.119-8.031), microvascular invasion (HR=2.556, 95% CI: 1.14-5.73), the post-treatment extent of disease (POSTTEXT) staging (IV vs. I: HR=244.204, 95% CI:11.306-5274.556), and alpha-fetoprotein (>100 ng/ml: HR=0.11, 95% CI: 0.032-0.381) for hepatoblastoma patients with neoadjuvant chemotherapy. High SIRI group had more patients with adverse NLR, SII, and POSTTEXT III (all p-value < 0.05). Independent prognostic factors led to an OS nomogram with a concordance index of 0.85 (95% CI: 0.78-0.91, p-value = 1.43e-27) and the calibration curve showed a good fit between the prediction curve and the true curve. Conclusions: SIRI is an independent prognostic factor of hepatoblastoma patients receiving neoadjuvant chemotherapy. The OS nomogram based on SIRI, POSTTEXT staging, MiVI, and AFP can be used to assess the prognosis of those patients.
ABSTRACT
BACKGROUND: This study aimed to screen the impact factors for clinical symptoms of prenatally diagnosed choledochal cysts (CDCs), to warn about the occurrence of clinical symptoms and the timing of surgery. METHODS: Medical records of patients with prenatally diagnosed CDCs admitted to our hospital from April 2013 to April 2018 were retrospectively reviewed. Fetal hilar or abdominal cysts were found by prenatal ultrasonogram. All patients underwent laparoscopic cyst excision and hepaticojejunostomy in our center. Univariate analysis and multivariate logistic regression analysis were performed to screen the factors related to clinical symptoms intimately. RESULTS: Two hundred eighteen cases were included. One hundred thirty-four patients (134/218, 61.5%) presented clinical symptoms before surgery. The results of univariate analysis showed that patients with clinical symptoms had earlier time of prenatal diagnosis (P = 0.002), higher values of GGT, TBIL, DBIL (P < 0.001, P < 0.001, P < 0.001, respectively) and larger maximum diameter of cyst before surgery (P = 0.012). Multivariate logistic regression analysis suggested that the time of prenatal diagnosis (P = 0.001, OR = 0.898, 95% CI: 0.845 ~ 0.955) and the GGT value within one week of life (P = 0.028, OR = 1.002, 95% CI: 1.000 ~ 1.003) were independent influencing factors for symptoms. CONCLUSIONS: For children with prenatally diagnosed CDCs, approximately 2/3 patients presented noticeable clinical symptoms before surgery. The time of prenatal diagnosis and the GGT value within 1 week of life were independent impact factors for the occurrence of clinical symptoms.

PURPOSE: Ectopic distal location of papilla of Vater (EDLPV) is an obvious pathological feature of choledochal cyst (CDC). This study aimed to investigate the correlation between EDLPV and clinical characteristics of CDCs. METHODS: Three groups were studied: Group 1 (G1), papilla in the middle third of second part of duodenum (n = 38); Group 2 (G2), papilla from the distal third of second part to the beginning of third part of duodenum (n = 168); Group 3 (G3), papilla from the middle of third part to fourth part of duodenum (n = 121). Relative variables among three groups were compared. RESULTS: Compared with G1 and G2, G3 patients had the largest cysts (relative diameter: 1.18 vs. 1.60 vs. 2.62, p < 0.001), the youngest age (20.52 vs. 19.47 vs. -3.40 months, p < 0.001), the highest rate of prenatal diagnosis (26.32% vs. 36.31% vs. 62.81%, p < 0.001), the lowest occurrence of protein plugs in common channel (44.74% vs. 38.69% vs. 16.53%, p < 0.001), and the most elevated total bilirubin level (7.35 vs. 9.95 vs. 28.70 µmol/L, p < 0.001). Prenatally diagnosed G3 patients had heavier liver fibrosis than G2 (13.16% vs. 1.67%, p = 0.015). CONCLUSION: The more distal papilla location, the more severe clinical characteristics of CDCs, suggesting a crucial role in its pathogenesis.

Butylated hydroxyanisole (BHA) is mainly used as a food additive due to its antioxidant properties, which prevent or delay oxidation reactions and extend the storage life of products. The widespread use of BHA has led to its extensive presence in various environmental matrices and human tissues. Food intake is the main route of human exposure to BHA. Under different conditions, BHA can produce different metabolites, with tert-butyl hydroquinone (TBHQ) being one of the major products. Several studies have shown that BHA could cause thyroid system damage, metabolic and growth disorders, neurotoxicity, and carcinogenesis. Mechanisms such as endocrine disruption, genotoxicity, disturbances of energy metabolism, reactive oxygen species (ROS) production, signaling pathways, and imbalances in calcium homeostasis appear to be associated with the toxic effects of BHA. Avoiding the toxic effects of BHA to the maximum extent possible is a top priority. Finding safe, non-toxic and environmentally friendly alternatives to BHA should be the focus of subsequent research. In all, this review summarized the current situation related to BHA and might make recommendations for future research directions. © 2023 Society of Chemical Industry.

Growth hormone secretagogue receptor 1a (GHS-R1a) is an important G protein-coupled receptor (GPCR) that regulates a variety of functions by binding to ghrelin. It has been shown that the dimerization of GHS-R1a with other receptors also affects ingestion, energy metabolism, learning and memory. Dopamine type 2 receptor (D2R) is a GPCR mainly distributed in the ventral tegmental area (VTA), substantia nigra (SN), striatum and other brain regions. In this study we investigated the existence and function of GHS-R1a/D2R heterodimers in nigral dopaminergic neurons in Parkinson's disease (PD) models in vitro and in vivo. By conducting immunofluorescence staining, FRET and BRET analyses, we confirmed that GHS-R1a and D2R could form heterodimers in PC-12 cells and in the nigral dopaminergic neurons of wild-type mice. This process was inhibited by MPP+ or MPTP treatment. Application of QNP (10 µM) alone significantly increased the viability of MPP+-treated PC-12 cells, and administration of quinpirole (QNP, 1 mg/kg, i.p. once before and twice after MPTP injection) significantly alleviated motor deficits in MPTP-induced PD mice model; the beneficial effects of QNP were abolished by GHS-R1a knockdown. We revealed that the GHS-R1a/D2R heterodimers could increase the protein levels of tyrosine hydroxylase in the SN of MPTP-induced PD mice model through the cAMP response element binding protein (CREB) signaling pathway, ultimately promoting dopamine synthesis and release. These results demonstrate a protective role for GHS-R1a/D2R heterodimers in dopaminergic neurons, providing evidence for the involvement of GHS-R1a in PD pathogenesis independent of ghrelin.

Lung cancer, a highly malignant disease, greatly affects patients' quality of life. N6-methyladenosine (m6A) is one of the most common posttranscriptional modifications of various RNAs, including mRNAs and ncRNAs. Emerging studies have demonstrated that m6A participates in normal physiological processes and that its dysregulation is involved in many diseases, especially pulmonary tumorigenesis and progression. Among these, regulators including m6A writers, readers and erasers mediate m6A modification of lung cancer-related molecular RNAs to regulate their expression. Furthermore, the imbalance of this regulatory effect adversely affects signalling pathways related to lung cancer cell proliferation, invasion, metastasis and other biological behaviours. Based on the close association between m6A and lung cancer, various prognostic risk models have been established and novel drugs have been developed. Overall, this review comprehensively elaborates the mechanism of m6A regulation in the development of lung cancer, suggesting its potential for clinical application in the therapy and prognostic assessment of lung cancer.

Background: Choledochal cyst (CDC) increases the risk (2.5%-30%) of malignancy. Metaplasia and dysplasia have been recognized as premalignant lesions among CDCs. This study aimed to evaluate the risk factors of metaplasia and dysplasia in CDC children. Methods: Two hundred and ten CDC children who underwent cyst excision and Roux-en-Y hepaticojejunostomy at our institution between July 2020 and November 2021 were included and randomly divided into the training set and validation set. Univariate and multivariate logistic regression analysis were used to identify independent risk factors of premalignant lesions in the training set and build a predictive nomogram. The performance and discriminatory abilities of the nomogram were further assessed and validated in the validation set. Results: Of the 210 CDC children, 78 (37.1%) patients developed premalignant lesions. Age (OR, 1.011, 95%CI, 1.000-1.022, P = 0.046), symptoms duration (OR, 1.021, 95%CI, 1.001-1.042, P = 0.036), cyst diameter (OR, 1.737, 95%CI, 1.328-2.273, P < 0.001), recurrent attacks of biliary pancreatitis (OR, 3.653, 95%CI, 1.205-11.076, P = 0.022), and biliary operation history (OR, 5.860, 95%CI, 1.268-27.084, P = 0.024) were identified as independent risk factors. Based on these predictors, a predictive nomogram was generated. The AUC of the nomogram was 0.873 in the training set and 0.793 in the validation set, indicating that it was robust and well calibrated. Conclusions: A novel nomogram to the individualized risk of premalignant lesions in CDC children was successfully built, on the basis of age, symptoms duration, cyst diameter, recurrent attacks of biliary pancreatitis, and biliary operation history. This nomogram, combined with the final pathological results, can help clinicians to develop more efficient follow-up strategies for the high-risk children with CDC.
ABSTRACT
PURPOSE: This study aimed to evaluate the effect of prenatal diagnosis at different gestational times on the clinical features of patients with choledochal cysts (CDCs). METHODS: Medical records of patients with prenatally diagnosed CDCs admitted to our hospital (April 2013-April 2018) were retrospectively reviewed. The clinical characteristics and pathological CDC features were analyzed. RESULTS: Two hundred eighteen cases were included. Patients were divided into two groups. Group 1 and group 2 had a prenatal diagnosis at ≤ 27 weeks of gestation (second trimester of gestation, n = 157) and > 27 weeks (third trimester of gestation, n = 61), respectively. The incidence of jaundice and the TBIL, IBIL and GGT levels were higher in Group 1 (P = 0.021, P = 0.029, P = 0.042, P = 0.007, respectively). The maximum cyst diameter at the time of surgery was larger in Group 1 (P = 0.015). An association study showed that the time of prenatal diagnosis was negatively correlated with the maximum cyst diameter both postnatally (r = - 0.223, P = 0.001) and at the time of surgery (r = - 0.268, P < 0.001). CONCLUSION: Unlike patients diagnosed at a late prenatal age, patients diagnosed at an early prenatal age tend to present clinical symptoms (jaundice, manifested as high indirect bilirubin), hepatic function damage, and large cysts at the time of surgery.

PURPOSE: Patients with choledochal cyst (CDC) develop liver fibrosis, especially advanced fibrosis without prompt surgery. This study validated the aspartate aminotransferase (AST)-to-platelet ratio index (APRI) and Fibrosis-4 index (FIB-4) and constructed a model for predicting advanced fibrosis in pediatric CDCs. METHODS: Between January 2020 and March 2022, 330 CDCs (advanced fibrosis: 34, Ludwig staging 3-4; non-advanced fibrosis: 296, Ludwig staging 0-2) were reviewed. APRI and FIB-4 were validated. The area under the receiver operating characteristic (AUROC) curve was used to assess discrimination. Relevant variables were analyzed by backward stepwise logistic regression. Enhanced bootstrap method was used for internal verification with 1000 samples. RESULTS: The AUROCs of APRI and FIB-4 were 0.761 (0.673-0.850) and 0.561 (0.455-0.667). AST to prealbumin ratio (APAR), was constructed with an AUROC of 0.776 (0.693-0.860). The AUROCs of APAR + APRI and APAR + FIB-4 were 0.791 (0.713-0.869) and 0.782 (0.699-0.865). No significant differences were noted in the AUROCs of the indices or their combinations. APAR and APRI could be used together to reduce missed diagnosis rate. The risk of advanced fibrosis varied from different APAR and APRI scores. CONCLUSION: Both APAR and APRI were indispensable to identify CDC patients at high risk of advanced fibrosis.

BACKGROUND: A posterior urethral diverticulum (PUD) is a serious postoperative complication after anorectal malformation correction. Complete resection is technical demanding because of limited retrourethral working space deep in the pelvis. OBJECTIVE: We pioneered the single-incision laparoscopic approach for PUD excision and evaluated the efficacy. DESIGN, SETTING, AND PARTICIPANTS: Twenty-six PUD patients undergoing redo surgeries between June 2011 and June 2021 were reviewed. SURGICAL PROCEDURE: A series of transabdominal retraction sutures were placed through the PUD to facilitate dissection. The contents were evacuated to create a working space. Distal PUD dissection was carried along the submucosal layer to prevent injury of the urethra/pelvic nerve complex. The rectal mucosa was peeled off from the junction site for complete PUD excision. The muscular cuff of the distal rectum was then oversewn. MEASUREMENTS: Operative time, postoperative recovery, and complications were assessed. RESULTS AND LIMITATIONS: The mean age of redo surgery was 2.46 yr. The average operative duration was 2.35 h. The mean postoperative hospital stay, resumption of full diet, and bowel movement were 10.23, 2.15, and 1.54 d, respectively. The median follow-up period was 46 mo (12-132 mo). No remnant of PUD, recurrent fistula, or urinary leak was detected. None of the patients had difficulty in urination, urinary dribbling, urinary tract infection, constipation, or soiling. All patients retained morning erection, and two postpubertal patients had ejaculations. CONCLUSIONS: Our single-incision laparoscopic redo surgery provides an effective approach for PUD excision. It minimizes complications. It also preserves urinary and bowel continence and sexual function. PATIENT SUMMARY: Complete resection of a posterior urethral diverticulum (PUD) in anorectal malformation is technically demanding because of limited retrourethral working space in the deep pelvis. The outcomes of single-incision laparoscopic PUD excision were satisfactory.

BACKGROUND: Journal Impact Factor™ (JIF) is often used to evaluate the relative reputation and quality of academic journals in their respective fields, and can greatly influence the quality and scope of subsequent manuscript submissions. Therefore, many if not all academic journals are interested in increasing their JIF, to improve their academic impact. AIM: To determine the importance of the integrity of the editorial and publication process in improving the academic influence of academic journals and the JIF of academic journals. METHODS: In this paper, we describe our statistical analysis of bibliometric factors - including the 2021 JIFs released in the Journal Citation Report™ 2022, discipline rankings, received and published articles in 2019-2021, and webpage visits and downloads - for seven journals published by Baishideng Publishing Group (Baishideng) and indexed in Science Citation Index Expanded™; ultimately, we introduce and discuss the editing and publishing processes of Baishideng's journals in their entirety, as they form the basis for our objective of safeguarding and bolstering integrity in academic publication. RESULTS: For the seven journals assessed, their 2021 JIFs were basically unchanged from 2020, with the current metric ranging from 5.374 for World Journal of Gastroenterology (WJG) to 1.534 for World Journal of Clinical Cases (WJCC). Further assessments of the journals' bibliometrics from 2019 to 2020, showed that World Journal of Stem Cells has the highest self-citation rate (1.43%) and World Journal of Gastrointestinal Surgery has the lowest (0.21%). Additionally, the total 3012 articles published during this period were cited by more than 20000 articles in approximately 8000 academic journals. Of note, the 1102 articles published in WJG were cited by articles in 3059 journals, among which 171 journals have a JIF of > 10, including internationally renowned academic journals such as CA-A Cancer Journal for Clinicians (2021 JIF 286.130, record count: 1), Lancet (2021 JIF 202.731, record count: 4), Nature Reviews Immunology (2021 JIF 108.555, record count: 2), Nature Reviews Gastroenterology & Hepatology (2021 JIF 73.082, record count: 9), Lancet Gastroenterology & Hepatology (2021 JIF 45.042, record count: 8), Gastroenterology (2021 JIF 33.883, record count: 19), and Gut (2021 JIF 31.793, record count: 21). This suggests that Baishideng's journals have been widely recognized for their academic quality. In the Reference Citation Analysis (RCA) database, all seven Baishideng-published journals obtained a 2022 Journal Article Influence Index (JAII). For example, WJG has a 2022 JAII of 22.048, ranking 18th out of 102 journals in the field of gastroenterology & hepatology in the RCA, with 469909 total citations (6/102) and 21313 total articles (5/102). The numbers of manuscripts received and published in 2021 were both higher than those in 2019-2020. For example, WJCC received a total of 3650 manuscripts in 2021, which is 91.1% higher than those in 2019-2020 (average: 1910 papers/year). In 2021, WJCC published 1296 articles, representing an increase of 105.1% compared to those in 2019-2020 (average: 632 articles/year). The numbers of webpage visits and downloads received by the seven journals have increased year by year. For example, the number of total visits received by WJG in 2019-2021 was 1974052 in 2019, 2317835 in 2020 (increased by 17.4% compared with that in 2019), and 2652555 in 2021 (increased by 4.4% compared with that in 2020). The visitors were from more than 220 countries and regions worldwide, such as the United States, China, and the United Kingdom. Open access (OA) plays a vital role in improving the quality, efficiency, transparency, and integrity of academic journal publishing. From 2019 to 2021, a total of 5543 OA articles were published in the seven journals, of which 2083 (37.6%) were invited and published free-of-charge. During the same period, 1683 articles were published in WJG, and the authors were from more than 70 countries and regions. For the total 5543 articles published in the seven journals from 2019 to 2021, 3903 article quality tracking reports were received after the online publication of these articles. The quality of the articles was further evaluated through the Baishideng's article quality and author evaluation tracking system, with 4655 articles (84.0%) having received author evaluation and feedback, which contributes to tracking metrics for authors' satisfaction with the collective publication processes. From March 25, 2021 to June 28, 2022, the seven journals received a total of 424 reader evaluations and 229 letters from readers; this subsequent reader engagement demonstrates that the popularity of the published articles and the volume of their readership audience were improved through the reader evaluation system. CONCLUSION: Ultimately, the findings from our bibliometric assessments indicate that establishing, promoting and actively practicing processes that safeguard and bolster the integrity of the editing and publication process also help to improve the academic influence of academic journals, which itself is the cornerstone for improving JIF.

Background: Postoperative adjuvant steroid therapy is regarded as the conventional treatment for patients with biliary atresia (BA) who have undergone Kasai portoenterostomy (KP). However, whether the steroid therapy can improve BA outcomes is controversial. This meta-analysis aimed to evaluate the effects of adjuvant steroid therapy on the surgical prognosis of BA. Methods: We searched related studies published in PubMed, Embase, Web of Science, Cochrane, and the Chinese National Knowledge Infrastructure database up to May 2022. Data on the effect of steroid use on the clinical prognosis of the patients, including the jaundice clearance rate (JCR), native liver survival rate (NLSR) at 6, 12, and 24 months after KP, and the incidence of cholangitis, were extracted. Subgroup analyses based on age at KP, administration method, initial dosage, and steroid type were conducted. Statistical analysis was conducted using Stata/SE 12.0. Results: Eleven articles (a total of 1,032 patients) were included in the present meta-analysis. The results demonstrated that postoperative adjuvant steroid therapy improved JCR at the 6/12/24-month follow-up (RR: 1.35, 95% CI: 1.18-1.55, p < 0.001; RR:1.49, 95% CI, 1.12-1.99, p = 0.006; RR: 1.41, 95% CI: 1.14-1.75, p = 0.002) and improved NLSR at the 24-month follow-up (RR: 1.31, 95% CI: 1.03-1.68, p = 0.028). However, steroids could not significantly improve NLSR at the 6/12-month follow-up (RR: 1.06; 95% CI: 0.98-1.15; p = 0.17; RR: 1.22; 95% CI: 0.97-1.54; p = 0.095), and might not decrease the incidence of postoperative cholangitis (RR: 0.78, 95% CI: 0.60-1.01, p = 0.058). Furthermore, subgroup analyses confirmed that three variables (age at KP, administration method, and initial dosage) could affect the efficacy of steroids in BA patients. Conclusion: Postoperative adjuvant steroid therapy can significantly improve bile flow. The superiority of steroid therapy was more remarkable in patients aged ≤70 days at KP than in those aged >70 days. Additionally, intravenous followed by oral steroid administration method and medium initial dosage seemed to have the more reliable efficiency on bile flow. And patients treated by steroid had better long-term (24-month) native liver survival, but there is no significant effect on short-term native liver survival and postoperative cholangitis. Further studies are warranted.
