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.
Objective:
Biliary atresia (BA) is a neonatal liver disease and requires Kasai portoenterostomy. Many patients develop postoperative cholangitis, resulting in a poor prognosis. The preventive strategy of antibiotics is empirical and lacks a standard regimen. We aimed to analyze the effect of different durations of prophylactic intravenous antibiotics against post-Kasai cholangitis.
Study Design:
A single-center, open-labeled, randomized clinical trial was performed from June 2016 to August 2017. One hundred and eighty BA patients were recruited and randomized into a short-term (n = 90) and a long-term (n = 90) treatment group, and prophylactic intravenous antibiotics were used for 7 versus 14 days, respectively. The primary outcome was the overall cholangitis incidence within 6-months post-Kasai portoenterostomy. The secondary outcomes included cholangitis incidence within 1 and 3 months post-Kasai portoenterostomy, the onset and average episodes of cholangitis, jaundice clearance rate, native liver survival rate, and adverse events within 6-months post-Kasai portoenterostomy.
Results:
The cholangitis incidence within 6-months post-Kasai in the short-term group was similar to the long-term group (62% vs. 70%, p = 0.27) with intention-to-treat and pre-protocol analysis. There was no significant difference in jaundice clearance rate or native liver survival rate between the two groups. However, the percentage of early onset (61% vs. 38%, p = 0.02) and average episodes (2.4 ± 0.2 vs. 1.8 ± 0.1 episodes, p = 0.01) of cholangitis were lower in the long-term group.
Conclusion:
Long-term intravenous antibiotics can be replaced by the short-term regimen in the general protection against post-Kasai cholangitis.
