Summary

The purpose of this study is to investigate the metastatic status of lateral pelvic lymph nodes in rectal neuroendocrine neoplasms (rNENs) undergoing laparoscopic total mesenteric excision (TME). The hypothesis is that the rate of lateral lymph node metastasis is underestimated in rNENs undergoing TME, necessitating concurrent lateral Pelvic lymph node dissection.

Conditions

  • Rectal Neuroendocrine Neoplasm

Interventions

PROCEDURE

lateral pelvic lymph node dissection

Following the total mesorectal excision principle, the rectum and mesentery are removed, with careful protection of the pelvic autonomic nerves. After completing laparoscopic rectal resection, lateral lymph node dissection is performed. The lateral dissection follows these steps: ① Open the peritoneum at the bifurcation of the iliac vessels, dissect along the retroperitoneum adjacent to the ureter-bladder fascia, expose the lateral pelvic area, and carefully protect the ureter and hypogastric nerves. Open the peritoneum along the edge of the external iliac vessels close to the inguinal ligament, clear the lymphatic fatty tissue alongside the external iliac vessels along the edge of the iliopsoas and internal oblique muscles; ② After identifying the hypogastric nerve, dissect along the bladder-bladder fascia, separate the bladder and the fat tissue around the lateral pelvic space, completely remove the lymphatic tissue around the internal iliac vessels and hypogastric nerves.
