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

## TL;DR

A new surgical technique using a single incision for both abdominal and chest biopsies in a rare infant tumor case is described.

## Contribution

A port-sharing procedure enables simultaneous laparoscopic and thoracoscopic biopsies through a single skin incision.

## Key findings

- A port-sharing approach successfully obtained biopsies from both abdominal and thoracic sites in an infant with neuroblastoma.
- The method reduced the number of port-side wounds compared to traditional approaches.
- The case suggests potential applicability for other patients needing combined thoracic and abdominal access.

## 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.
