Retrospective Comparative Study of Two Different Endoscopic Treatments for Rectal Neuroendocrine Neoplasms

Обзор

The aim is to compare the safety and efficacy of endoscopic submucosal dissection (ESD) versus endoscopic partial muscle resection( EPMR) for the treatment of rectal neuroendocrine neoplasms (R-NENs), thereby providing guidance for optimizing therapeutic strategies. The investigators retrospectively analyzed consecutive patients with R-NENs who underwent endoscopic resection at our center between January 2020 and February 2026. Patients were assigned to either the ESD group or the EPMR group. Baseline characteristics and perioperative outcomes were compared, including the number of lesions, maximum lesion diameter, single-lesion procedure time, postoperative complications, positive margin rate, pathological staging, lymphovascular invasion, and the need for additional therapies.

Подробное описание

The investigators compared the safety and efficacy of endoscopic submucosal dissection (ESD) versus endoscopic partial muscle resection( EPMR) for the treatment of rectal neuroendocrine neoplasms (R-NENs), thereby providing guidance for optimizing therapeutic strategies. The investigators retrospectively analyzed consecutive patients with R-NENs who underwent endoscopic resection at our center between January 2020 and February 2026. Patients were assigned to either the ESD group or the EID group. Baseline characteristics and perioperative outcomes were compared, including the number of lesions, maximum lesion diameter, single-lesion procedure time, postoperative complications, positive margin rate, pathological staging, lymphovascular invasion, and the need for additional therapies. Through this comparative analysis, The investigators would identify the optimal endoscopic technique for treating rectal neuroendocrine tumors.

Вмешательства

  • Процедура endoscopic intermuscular dissection (EID)
    EID:Endoscopic Intermuscular Dissection (EID) is an ultra-minimally invasive technique derived from conventional Endoscopic Submucosal Dissection (ESD). Its core principle is not merely to dissect within the submucosal layer, but to "deepen" the dissection plane into the muscularis propria of the rectal wall. Specifically, the surgeon utilizes the natural anatomical plane between the inner circular muscle and the outer longitudinal muscle layers for precise dissection. This procedure involves re
  • Процедура Endoscopic Submucosal Dissection (ESD)
    ESD: A solution is injected beneath the mucosa to create a submucosal cushion, followed by the use of specialized electrosurgical knives to dissect directly within the submucosal layer, thereby achieving en bloc resection of the tumor.
