Is this trial a fit for you?

Likely a good fit

Ideal candidates are infants aged 14 to 90 days diagnosed with type-III biliary atresia who have undergone Kasai portoenterostomy.

Probably not a fit

Patients with cholestasis due to non-biliary atresia diseases or those who have undergone surgery at other institutions may not benefit from this study.

What this trial studies

This study investigates the effectiveness of prophylactic oral antibiotics in preventing cholangitis in infants with biliary atresia after undergoing Kasai portoenterostomy. It is designed as a non-inferiority trial, comparing the rates of cholangitis in patients who receive antibiotics versus those who do not. The study will follow patients for two years post-surgery to assess outcomes. Given the high incidence of cholangitis and the variability in antibiotic use, this research aims to provide high-quality evidence regarding the benefits and risks of long-term antibiotic prophylaxis.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of cholangitis in biliary atresia patients, improving their overall health outcomes.

How similar studies have gone: While there is ongoing debate regarding the use of prophylactic antibiotics in similar contexts, high-quality evidence supporting their effectiveness remains limited, making this approach relatively novel.
