Abstract:
Lateral lymph node metastasis (LLNM) is the main metastatic mode and the major cause of locoregional recurrence of mid-low rectal cancer. Single chemoradiotherapy cannot achieve good local control for LLNM, while the argument against performing lateral lymph node dissection (LLND) is the increased rate of urinary and sexual dysfunction after surgery. Ultra-high definition surgical field and delicate resolution by 4K laparoscopic surgical system will be helpful to achieve good tumor clearance and function preservation by identification and exposure of the important anatomic structures such as pelvic autonomic nerve and internal iliac vessels. Therefore, selective LLND can reduce local recurrence rates, particularly in the pelvic sidewall. LLND with autonomic nerve preservation by 4K laparoscopic system is expected to further decrease the risk of perioperative complications and urinary and sexual dysfunction in appropriate patients with neoadjuvant chemoradiotherapy.
