[Laparoscopic nephron-sparing surgery for Wilms tumor: description of two cases]

Area of Science:

• Pediatric Surgery
• Surgical Oncology
• Nephrology

Background:

• Wilms tumor is a common pediatric kidney cancer, primarily treated with surgical resection.
• Advancements in large study group research have significantly decreased Wilms tumor mortality rates.
• Minimally invasive surgical techniques are increasingly explored to reduce patient morbidity.

Observation:

• This study details two pediatric cases of Wilms tumor treated with laparoscopic nephron sparing surgery.
• Case 1 involved a patient with Beckwith-Wiedemann syndrome and bilateral Wilms tumors.
• Case 2 presented a non-syndromic patient with unilateral Wilms tumor.

Findings:

• The laparoscopic nephron sparing surgery was performed using an intraperitoneal approach in both cases.
• No intraoperative complications were encountered during the procedures.
• Follow-up assessments at 18 months (Case 1) and six months (Case 2) revealed no evidence of tumor recurrence or metastatic disease.

Implications:

• Laparoscopic nephron sparing surgery is a viable and safe option for select pediatric patients with Wilms tumor.
• This minimally invasive technique may help preserve renal function and reduce long-term morbidity.
• Further research into minimally invasive approaches can refine treatment strategies for Wilms tumor.
