Area of Science:

  • Surgical Oncology
  • Minimally Invasive Surgery
  • Anatomical Studies

Background:

  • Axillary lymph node dissection is a standard procedure for staging and treating breast cancer and extremity melanoma.
  • Conventional axillary dissection is associated with significant patient morbidity.
  • Minimally invasive techniques are being explored to reduce surgical complications.

Purpose of the Study:

  • To evaluate the feasibility and advantages of endoscopic axillary lymph node dissection compared to conventional open surgery.
  • To assess the safety and efficacy of using a preperitoneal distention balloon (PDB) system for endoscopic axillary dissection.

Main Methods:

  • Twenty endoscopic axillary dissections and 10 lymph node samplings were performed on 10 human cadavers.
  • A preperitoneal distention balloon (PDB) system was utilized for endoscopic visualization and dissection.

Related Experiment Videos

  • Procedures were followed by open surgery in four cadavers for direct comparison.
  • Pathological examination of axillary contents confirmed lymphatic tissue retrieval.

    • Main Results:

    • The endoscopic technique provided excellent access and clear visualization of critical anatomical structures, including the axillary vein and nerves.
    • Surgical outcomes and specimen quality were comparable to traditional open dissection methods.
    • The PDB system facilitated safe and effective dissection in the axillary space.

    Conclusions:

    • Endoscopic axillary lymph node dissection is a technically feasible procedure for breast cancer and extremity melanoma.
    • This approach demonstrates potential for reduced morbidity compared to open surgery.
    • Further clinical trials in patients are warranted to confirm these findings and establish definitive conclusions.
