Beskrivelse
Inclusion Criteria:
- Patients undergoing endoscopic treatment for rectal neuroendocrine neoplasms.
- Lesion diameter less than 2 cm.
- Preoperative auxiliary examinations indicating no peripheral lymph node or distant metastasis.
- Endoscopic surgical approach limited to ESD or EPMR.
Exclusion Criteria:
- Use of non-ESD or non-EPMR endoscopic techniques, such as ligation-assisted resection or Endoscopic Mucosal Resection (EMR).
- Presence of other conditions deemed by the investigator to be unsuitable for participation in this study.
- Patient or family refusal to participate.

Aktiv komparator: ESD group
The ESD group would enroll cases undergoing endoscopic treatment for rectal neuroendocrine neoplasms, and the treatment method of all cases in this group should be 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.
|
|
Eksperimentel: EID group
The EPMR group would enroll cases undergoing endoscopic treatment for rectal neuroendocrine neoplasms, and the treatment method of all cases in this group should be endoscopic partial muscle resection ( EPMR).
|
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 resecting part of the affected inner circular muscle while preserving the integrity of the outer longitudinal muscle layer.

the positive margin rate
Tidsramme: One week after the endoscopic treatment
|
A positive margin indicates that cancer cells extend to the edge of the removed specimen, suggesting that residual tumor may remain in situ.
The positive margin rate is calculated as the number of cases with positive margins divided by the total number of resected cases, expressed as a percentage.
It serves as a critical quality indicator for the completeness of tumor removal.
