Area of Science:

  • Surgical Oncology
  • Rectal Cancer Management
  • Minimally Invasive Surgery

Background:

  • Rectal cancer treatment has advanced with neoadjuvant chemoradiotherapy and total mesorectal excision, achieving excellent oncological outcomes.
  • However, lateral nodal disease remains a significant cause of local recurrence, with rates up to 30% in affected patients.
  • Lateral pelvic lymph node dissection (LPLND) has demonstrated oncological benefits in reducing local recurrence, particularly in the lateral compartment.

Purpose of the Study:

  • To review current evidence on managing lateral nodal disease in rectal cancer.
  • To highlight technical advancements and outcomes of minimally invasive LPLND (laparoscopic and robotic).

Main Methods:

  • Review of recent literature on lateral nodal disease management in rectal cancer.
  • Focus on the technical aspects and outcomes of laparoscopic and robotic lateral pelvic lymph node dissection.

Main Results:

  • Minimally invasive LPLND (laparoscopic and robotic) shows feasibility and favorable short- and long-term outcomes.
  • These approaches offer advantages over open surgery, including reduced bleeding and enhanced visualization of pelvic anatomy.
  • Precise autonomic nerve preservation during minimally invasive LPLND minimizes postoperative genitourinary dysfunction.

Conclusions:

  • Lateral pelvic lymph node dissection is crucial for managing lateral nodal disease in rectal cancer to prevent local recurrence.
  • Laparoscopic and robotic approaches are becoming standardized and offer significant benefits for LPLND.
  • Minimally invasive LPLND is a safe and effective technique with potential for widespread adoption.
