Endosurgical procedures for pediatric solid tumors, including neuroblastoma and ovarian tumors, offer shorter hospital stays and faster feeding post-operation. While effective and minimally invasive, careful patient selection is needed to minimize complications and conversions to open surgery.

Area of Science:

  • Pediatric Surgery
  • Surgical Oncology
  • Minimally Invasive Surgery

Background:

  • Pediatric solid tumors require effective diagnostic and therapeutic interventions.
  • Endosurgical (laparoscopic) techniques offer a minimally invasive approach for tumor management.
  • Comparison with traditional open surgery is essential to evaluate benefits and risks.

Purpose of the Study:

  • To evaluate the advantages and complications of endosurgical procedures for benign and malignant pediatric solid tumors.
  • To compare endosurgical techniques with open surgery regarding operational outcomes and complications.
  • To assess the effectiveness of laparoscopic biopsy and excision in pediatric oncology.

Main Methods:

  • Retrospective analysis of 24 biopsies and 24 excisions performed laparoscopically for neuroblastoma, ovarian, and other solid tumors since July 1997.

  • Comparison of operative length, blood loss, postoperative feeding time, chemotherapy initiation, and hospital stay between endosurgical and open surgery groups.
  • Analysis of intraoperative and postoperative complications, including conversions to open surgery and port-site recurrences.

    • Main Results:

    • Endosurgical procedures resulted in significantly shorter hospital stays and earlier initiation of postoperative feeding for abdominal neuroblastoma and ovarian tumors compared to open surgery.
    • Time to start postoperative chemotherapy was reduced only in the abdominal neuroblastoma group.
    • Two cases required conversion to open surgery due to large tumor size; one case had cerebrospinal fluid leakage post-thoracoscopic excision.

    Conclusions:

    • Endosurgical procedures are effective and minimally invasive for pediatric solid tumors.
    • Careful patient selection and improved indicators are necessary to prevent complications and reduce conversions to open surgery.
    • Laparoscopic techniques demonstrate significant benefits in recovery time for specific pediatric tumor types.
