Summary
Laparoscopic nephrectomy is a safe and feasible surgical option for children with Wilms tumor following preoperative chemotherapy. This minimally invasive approach allows for complete tumor removal and lymph node sampling with minimal complications.
Area of Science:
- Pediatric Oncology
- Minimally Invasive Surgery
- Pediatric Urology
Background:
- Wilms tumor is the most common pediatric kidney cancer.
- Preoperative chemotherapy is a standard treatment for Wilms tumor.
- Surgical management aims for complete tumor resection and lymph node sampling.
Observation:
- Two pediatric patients with unilateral Wilms tumor received preoperative chemotherapy (vincristine/actinomycin D).
- Both patients underwent successful laparoscopic nephrectomy and lymph node sampling using a transperitoneal approach.
- Tumor extraction was achieved without morcellation through a small incision.
Findings:
- Complete tumor and lymph node removal was confirmed in both cases.
- Minimal intraoperative blood loss (50 ml) was recorded.
- Patients experienced uncomplicated postoperative recovery and were discharged within 3 days.
Implications:
- Laparoscopic nephrectomy is a viable and safe surgical technique for pediatric Wilms tumor post-chemotherapy.
- This approach facilitates complete surgical resection, crucial for oncologic outcomes.
- Further studies with longer follow-up and larger cohorts are needed to compare laparoscopic outcomes with open surgery.
