Laparoscopic Lateral Pelvic Lymph Node Dissection for Advanced Lower Rectal Cancer: a Preliminary Vietnamese Study

Area of Science:

• Surgical Oncology
• Gastrointestinal Surgery
• Rectal Cancer Treatment

Background:

• Lateral pelvic lymph node dissection (LPLD) is debated for rectal cancer regarding feasibility, safety, and oncological outcomes.
• This study evaluates short-term outcomes, safety, and feasibility of LPLD in lower rectal cancer patients.

Discussion:

• LPLD identified lateral pelvic lymph node metastasis in 16% of advanced lower rectal cancer cases.
• The LPLD group experienced a significantly higher rate of intraoperative complications (16.0%) versus TME alone (3.3%).
• No significant difference in postoperative complication rates was observed between LPLD and TME-only groups.

Key Insights:

• LPLD is a safe and feasible surgical option for advanced lower rectal cancer.
• The procedure can detect lateral pelvic lymph node metastasis, crucial for staging and treatment.
• While intraoperative risks are elevated, long-term postoperative outcomes appear comparable to standard TME.

Outlook:

• Further research with larger patient cohorts and extended follow-up is essential.
• Long-term oncological outcomes and survival rates need comprehensive evaluation.
• Refining LPLD techniques may mitigate intraoperative risks and improve patient safety.
