Abstract
AIM OF THE STUDY: The outcome of Kasai operation is not uniformly successful. This objective of this study is to identify risk factors that predict early failure of this operation. METHODS: A retrospective study was carried out for all patients who received Kasai operation between 1980 and 2012. Patients referred from other centers for liver transplantation because of failed Kasai operation were also recruited. MAIN RESULTS: A total of 185 patients were reviewed. A total of 119 (64.3%) patients failed Kasai operation, whereas 86 (46.5%) were considered as cases of early failure (<3 years post-Kasai). With univariate analysis, the presence of associated anomaly (RR: 1.90, 95%CI 1:45-2:36), operation with laparoscopic surgery (RR: 3.14, 95% CI: 2.39-5.42), delayed clearance of jaundice (RR: 1.89, 95% CI: 1.56-2.67), and repeated cholangitis (RR: 2.56, 95% CI: 1.39-3.42) were associated with adverse outcome, whereas the use of adjuvant steroid at post-operative period appeared to be protective (RR: 0.64, 95% CI: 0.29-0.93). With multivariate analysis, repeated cholangitis was an independent risk factor for early failure after Kasai operation (RR: 3.16, 95% CI: 1.83-4.62). Furthermore, it was also considered as a risk factor for failure after 3 year post-Kasai (RR: 2.07, 95% CI: 1.43-3.42). CONCLUSION: Patients with above risk factors are prone to fail Kasai operation in an early stage and require more frequent monitoring. Prevention and aggressive management of cholangitis should be considered as measures to avoid disease progression in the early stage. Lastly, performing open Kasai operation and the use of adjuvant steroid are potentially beneficial.
