External and internal-external biliary drainage in children with malignant obstructive jaundice

Area of Science:

• Pediatric Oncology
• Interventional Radiology
• Hepatobiliary Medicine

Background:

• Obstructive jaundice presents a significant clinical challenge in pediatric cancer patients.
• Percutaneous transhepatic biliary drainage is a standard treatment for adults but less documented in children.
• Limited data exists on the efficacy and safety of biliary drainage in pediatric oncology.

Purpose of the Study:

• To evaluate the safety and efficacy of external or internal-external biliary drainage in children with malignant obstructive jaundice.
• To assess the technical success and complication rates of this procedure in a pediatric population.
• To provide evidence for the utility of biliary drainage in managing pediatric cancer-related biliary obstruction.

Main Methods:

• Retrospective analysis of six pediatric patients (ages 1-17 years) with malignant obstructive jaundice.
• Inclusion of patients undergoing external or internal-external biliary drainage.
• Monitoring of biochemical, hematological, and microbiological parameters pre- and post-procedure (7-9 days).

Main Results:

• Technical success of external or internal-external biliary drainage was achieved in all six pediatric patients.
• No instances of clinically significant biliary sepsis were observed.
• One patient experienced asymptomatic duodenal perforation, attributed to a bulky duodenal tumor after drainage conversion.

Conclusions:

• External biliary drainage is a technically successful and viable option for pediatric patients with malignant obstructive jaundice.
• The procedure demonstrates a favorable safety profile in this pediatric cohort.
• This study supports the use of external biliary drainage as a therapeutic intervention in pediatric oncology.
