Insights

Short-term prophylactic antibiotics are effective in preventing post-Kasai cholangitis in biliary atresia patients. This approach offers similar protection to longer regimens, simplifying care.

Area of Science:

  • Pediatric Surgery
  • Hepatology
  • Infectious Diseases

Background:

  • Biliary atresia (BA) is a critical neonatal liver condition necessitating Kasai portoenterostomy.
  • Postoperative cholangitis is a frequent complication following Kasai portoenterostomy, leading to poorer patient outcomes.
  • Current antibiotic prophylaxis strategies for post-Kasai cholangitis lack standardization.

Purpose of the Study:

  • To evaluate the efficacy of different durations of prophylactic intravenous antibiotics in preventing cholangitis after Kasai portoenterostomy for biliary atresia.
  • To compare the incidence, onset, and severity of cholangitis between short-term (7 days) and long-term (14 days) antibiotic regimens.

Main Methods:

  • A single-center, randomized clinical trial involving 180 biliary atresia patients undergoing Kasai portoenterostomy.
  • Patients were randomized into two groups: short-term (7 days) and long-term (14 days) prophylactic intravenous antibiotic administration.
  • Primary outcome: overall cholangitis incidence within 6 months post-surgery. Secondary outcomes included early cholangitis incidence, episodes, jaundice clearance, and native liver survival.

Main Results:

  • The overall incidence of cholangitis within 6 months was comparable between the short-term and long-term antibiotic groups (62% vs. 70%, p=0.27).
  • No significant differences were observed in jaundice clearance rates or native liver survival between the groups.
  • The long-term group showed a significantly lower percentage of early-onset cholangitis (38% vs. 61%, p=0.02) and fewer average episodes (1.8 vs. 2.4, p=0.01).

Conclusions:

  • Short-term prophylactic intravenous antibiotic regimens are a viable alternative to long-term administration for preventing post-Kasai cholangitis in biliary atresia.
  • While overall incidence is similar, longer antibiotic courses may reduce early-onset cholangitis and the number of episodes.
