Summary
Endoscopic axillary dissection is a feasible minimally invasive technique for breast cancer staging. This cadaver study demonstrated its safety and effectiveness in removing lymph nodes, paving the way for patient trials.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
- Breast Cancer Management
Background:
- Axillary lymph node dissection is crucial for breast carcinoma staging.
- Minimally invasive techniques offer potential alternatives to open surgery.
- Endoscopic approaches are being explored for axillary lymph node dissection.
Purpose of the Study:
- To evaluate the technical feasibility of endoscopic axillary lymph node dissection.
- To assess the safety of an endoscopic approach in human cadavers.
- To compare endoscopic dissection with traditional open methods.
Main Methods:
- Twelve axillary dissections were performed on seven human cadavers.
- A small incision was used to access the axillary space, expanded with a balloon dissector.
- Endoscopic dissection utilized three to four 5-mm ports for visualization and instrument insertion.
Main Results:
- The average dissection time was 56.7 minutes.
- Key neurovascular structures, including the axillary vein and thoracic nerves, were successfully visualized.
- An average of 9.9 lymph nodes were removed per axilla, with no reported neurovascular injuries.
Conclusions:
- Endoscopic axillary dissection is technically feasible with current technology.
- The procedure demonstrated safety in cadaveric dissection.
- Further clinical trials in breast carcinoma patients are recommended to validate this technique.
