Clinical Report: Minimally Invasive Laparoscopic Catheterization with Bleomycin Quadruple Sclerotherapy

Overview

This study presents a case series of five pediatric patients with massive retroperitoneal lymphatic malformations (rLMs) treated using a novel minimally invasive technique combining laparoscopic catheterization and bleomycin quadruple sclerotherapy. All patients achieved clinical cure with minimal complications and favorable outcomes.

Background

Retroperitoneal lymphatic malformations are rare congenital anomalies that pose significant surgical challenges due to their complex anatomy and proximity to vital structures. Traditional treatment methods often result in high complication and recurrence rates, necessitating the exploration of safer, more effective minimally invasive alternatives. This study aims to establish a standardized protocol for managing massive rLMs using laparoscopic techniques.

Data Highlights

Key Findings

• All patients completed treatment without conversion to open surgery or adjacent organ injury.
• Mean operation time was 128 ± 25 minutes with minimal blood loss (2 ± 2 mL).
• Patients ambulated within 6 hours and resumed oral intake at 20 ± 3 hours post-surgery.
• One patient experienced a grade I complication (self-limiting abdominal discomfort); no higher-grade complications were observed.
• All patients achieved clinical cure with complete radiographic resolution during a median follow-up of 46 months.

Clinical Implications

The findings suggest that laparoscopic catheterization combined with bleomycin quadruple sclerotherapy is a safe and effective treatment for massive rLMs, offering a minimally invasive alternative to traditional surgical approaches. This technique may reduce the risk of complications and improve recovery times for pediatric patients.

Conclusion

Laparoscopic intracavitary catheterization with bleomycin quadruple sclerotherapy represents a promising minimally invasive strategy for managing massive retroperitoneal lymphatic malformations, with favorable outcomes and a low complication profile.
