Summary
Laparoscopic lateral pelvic lymph node dissection (LPLD) after rectal cancer surgery is feasible. This minimally invasive approach offers reduced blood loss and transfusion rates compared to open surgery, with comparable lymph node removal.
Area of Science:
- Surgical Oncology
- Minimally Invasive Surgery
- Rectal Cancer Management
Background:
- Advanced lower rectal cancer requires comprehensive treatment.
- Lymph node status is critical for prognosis and treatment planning.
- Lateral pelvic lymph node dissection (LPLD) is a component of surgical management.
Purpose of the Study:
- To assess the technical feasibility of laparoscopic LPLD following total mesorectal excision (TME).
- To evaluate LPLD as prophylaxis in rectal cancer patients without lymph node metastasis.
- To compare laparoscopic versus open LPLD outcomes.
Main Methods:
- TME followed by LPLD in 30 patients with lower rectal cancer.
- Laparoscopic LPLD (LAP group, n=12) versus open LPLD (Open group, n=18).
- Comparison of harvested lymph nodes, operative time, blood loss, and transfusion parameters.
Main Results:
- No significant difference in the number of harvested lymph nodes between groups.
- Longer operative time in the LAP group.
- Significantly lower operative blood loss, transfusion rate, and volume in the LAP group.
Conclusions:
- Laparoscopic LPLD is safe and feasible for selected rectal cancer patients by experienced teams.
- Laparoscopic LPLD achieves oncologic clearance comparable to open surgery.
- This approach may mitigate the higher blood loss and urinary dysfunction associated with open LPLD.
