Area of Science:

Surgical Oncology
Colorectal Surgery
Minimally Invasive Surgery

Background:

Lateral pelvic lymph node dissection (LPLND) is crucial for advanced rectal cancer but technically challenging.
The transanal approach for total mesorectal excision (TME) is gaining traction.
Integrating LPLND with transanal TME offers potential benefits.

Observation:

A two-team approach was utilized, entering the lateral pelvic area transanally.
Dissection involved separating fatty tissues from pelvic structures and vessels.
The obturator nerve was preserved while vessels were resected.

Findings:

The two-team method significantly reduced operative time and surgeon strain.
Transanal assistance facilitated secure and effective dissection, particularly in distal areas.
This approach enhances dissection around critical vessels like the internal pudendal and inferior vesical arteries.

Implications:

This combined technique offers a safe and effective method for LPLND in rectal cancer.
It may improve outcomes for patients requiring advanced rectal cancer surgery.
This technical note highlights a valuable advancement in surgical strategy for rectal cancer treatment.
