Summary
Robotic extended lateral pelvic lymph node dissection (LPLD) is a safe and feasible minimally invasive approach for advanced low rectal cancer. This technique demonstrated successful completion in all patients, with no operative conversions or LPLD-related morbidity.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
- Robotic Surgery
Background:
- Advanced low rectal cancer often presents challenges in achieving adequate lymph node clearance.
- Lateral pelvic lymph node dissection (LPLD) is crucial for staging and treatment, but traditionally involves significant morbidity.
Purpose of the Study:
- To assess the technical feasibility and safety of robotic-assisted extended lateral pelvic lymph node dissection (LPLD).
- To evaluate the oncologic outcomes and functional results of robotic LPLD in patients with advanced low rectal cancer.
Main Methods:
- A retrospective review of 8 consecutive robotic LPLD cases for advanced low rectal cancer with preoperative lateral node metastasis diagnosis.
- Analysis of patient demographics, operative time, blood loss, lymph node yield, morbidity, and functional outcomes.
Main Results:
- All 8 robotic LPLD procedures were completed successfully without conversion to open surgery.
- Mean operative time was 38 minutes, with an average of 4.1 lateral lymph nodes harvested.
- 38% of patients had lymph node metastases; 25% experienced postoperative morbidity, with no LPLD-related complications.
Conclusions:
- Robotic extended LPLD is a safe and technically feasible minimally invasive surgical option for advanced low rectal cancer.
- Further large-scale comparative studies are warranted to validate these findings against conventional surgical methods.
