Effects of postoperative adjuvant steroid therapy on the outcomes of biliary atresia: A systematic review and updated meta-analysis

Abstract

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.

Prognostic factors and outcomes of Kasai portoenterostomy (KPE): nine-year experience from a lower-middle income country

“…Being a retrospective analysis, we took available bilirubin level closest to 3 months (within 3 weeks) which in some instances might have been too early. Majority of our sample have not received adjuvant steroids which have shown to improve jaundice clearance [12,13]. Studies have shown in CMV -associated biliary atresia COJ can be as low as 15% [14] .Exact prevalence of congenital CMV infection in Sri Lanka is not known but postulated to be much higher than in western countries [15].…”

Dexamethasone may affect the occurrence of parenteral nutrition-associated cholestasis in preterm neonates

“…Adjuvant steroid therapy has become popular for the postoperative management of biliary atresia in infants ( 6 , 23 ) because steroid therapy improves jaundice clearance. However, it has been questioned that postoperative steroid therapy did not bring certain benefits for patients with biliary atresia in some studies ( 24 ). Due to the inconsistency of previous research results, the impact of postoperative steroid treatment on the prognosis of biliary atresia patients is questionable.…”

Major surgical conditions of childhood and their lifelong implications: comprehensive review

“…After surgery, the use of steroids is widely adopted for its anti-inflammatory effect and promotion of bile flow. A recent RCT and meta-analysis both confirmed that postoperative adjuvant steroid therapy improved bile drainage and native liver survival 161 , 162 . Recurrent cholangitis is another significant factor which negatively affects native liver survival.…”
