Endoscopic Resection for Small Rectal Neuroendocrine Tumors
June 27, 2022 updated by: Nanfang Hospital of Southern Medical University
Modified Cap-assisted Endoscopic Mucosal Resection and Endoscopic Submucosal Dissection for Small Rectal Neuroendocrine Tumors Less Than 1 cm: a Muticenter Randomized Noninferiority Trial
In previous single center study, both modified cap-assisted endoscopic mucosal resection (mEMR-C) and endoscopic submucosal dissection (ESD) were reported to be effective for the treatment of small rectal neuroendocrine tumors (NETs) and mEMR-C was inferior to ESD for the treatment of small rectal NETs (≤10 mm), as it has shorter operation times and lower hospitalization costs.
However, a multicenter randomized controlled trial is needed to prove the universality and generality of these findings.

Description
Inclusion Criteria:
- Age from 18 to 75 years;
- With a high suspicion or evidence of rectal NET assessed using EUS or colonoscopy;
- With tumor size ≤10 mm assessed by colonoscopy;
- Plan to receive mEMR-C or ESD treatment and provide written informed consent;
Exclusion Criteria:
- Unable to tolerate ESD or MEMR-C as assessed by the research team of each center;
- Complicated with serious diseases such as malignant tumor, which may lead to shorter life expectancy, the research team considers that it is not suitable for inclusion in the study after comprehensive evaluation;
- Rectal NET with lymph node metastasis or distant metastasis;
- Received resection of rectal neuroendocrine tumor by other surgical procedures;
- Multiple rectal neuroendocrine tumors;
- Vulnerable groups such as pregnant women or patients with mental disorders;
- Poor compliance, unable to cooperate with treatment.

Arms and Interventions

Intervention / Treatment |
---|---|
Experimental: mEMR-C group
In mEMR-C group, enrolled patients will receive modified EMR-C without submucosal injection.
|
A transparent cap with an inner groove (MH-593; Olympus, Tokyo, Japan) was attached to the forward-viewing colonoscope.
After the endoscope was inserted into the rectum, a crescent-shaped electrosurgical snare was passed through the sheath and looped along the inner groove of the cap.
Submucosal injections were not required in this method.
The tumor was suctioned into the cap and grasped by tightening the snare.
After confirming the appropriate snare placement, both the tumor and overlying mucosa were resected using electric cautery (Endocut Q, effect 2, VIO 200D; ERBE, Tübingen, Germany), and the resected tumor was sent for pathological examination.
Endoscopic examination was repeated without a transparent cap to evaluate the wound carefully in cases of perforation or bleeding and to ensure the absence of residual tumor tissues.
If there was spurting or active bleeding, hot forceps were used to stop the bleeding.
|
Active Comparator: ESD group
In ESD group, enrolled patients will receive the standard treatment modality of ESD to remove the rectal NET
|
ESD was performed as the standard procedure and has been widely described and used.
First, dots were marked approximately 5 mm from the periphery of the lesion using coagulation.
Subsequently, a diluted sodium hyaluronate solution with indigo carmine dye was injected submucosally.
Mucosal incision and submucosal dissection were performed using a T-Type ESD Knife (Micro-Tech, Nanjing, China) or Dual-knife (Olympus Medical, Tokyo, Japan).
After resection was completed, all visible vessels on the artificial wound were thoroughly coagulated to prevent postoperative bleeding.
