"Post-Kasai Portoenterostomy Cholangitis: What Have We Learnt So Far?"

Area of Science:

• Hepatology
• Infectious Diseases
• Surgical Complications

Background:

• Post-Kasai portoenterostomy (KPE) cholangitis is a frequent complication impacting liver function and survival.
• Current diagnostic definitions and management guidelines for post-KPE cholangitis are lacking.
• Effective management is crucial to prevent liver damage and decompensation.

Purpose of the Study:

• To review current research on diagnostic advancements for post-KPE cholangitis.
• To summarize therapeutic challenges and antibiotic strategies for managing cholangitis.
• To highlight the potential of novel molecular techniques in diagnosis.

Main Methods:

• Literature review of diagnostic approaches for post-KPE cholangitis.
• Analysis of current evidence on antibiotic prophylaxis and treatment.
• Exploration of metagenomic next-generation sequencing (mNGS) in pathogen detection.

Main Results:

• No consensus exists on the definition or management of post-KPE cholangitis.
• Metagenomic next-generation sequencing shows promise for broader pathogen detection, including in blood culture-negative cases.
• Evidence on antibiotic prophylaxis efficacy is conflicting, with unsettled questions on optimal use.

Conclusions:

• Improved diagnostic criteria and standardized management guidelines for post-KPE cholangitis are needed.
• Molecular diagnostic techniques like mNGS offer potential for earlier and more accurate diagnosis.
• Further research is required to optimize antibiotic strategies for cholangitis prevention and treatment.
