Simultaneous Laparoscopic and Thoracoscopic Biopsy via a Single Skin Incision Using a Port-Sharing Procedure in Infantile Neuroblastoma: A Case Report

Abstract

Neuroblastoma, typically presenting with atypical symptoms, rarely manifests as a urachal tumor. We report a case of urachal neuroblastoma wherein a single port site was used for both laparotomy and thoracoscopy. A 1-month-old female presented with umbilical discharge. Enhanced computed tomography revealed a urachal tumor, later confirmed pathologically as neuroblastoma without MYCN amplification. During chemotherapy for low-risk classification, a right adrenal mass and mediastinal lymphadenopathy emerged, prompting further biopsy. We employed a port-sharing procedure at the right hypochondrium to perform simultaneous laparoscopic and thoracoscopic biopsies, reducing the number of port-side wounds. This approach could be applicable in other cases requiring combined thoracic and abdominal surgical access.
