Summary

Cap-assisted endoscopic mucosal resection (EMR-C) and endoscopic submucosal dissection (ESD) have both been reported to be effective treatment methods for small rectal neuroendocrine tumor (NET) in limited studies. Which one is better has not been determined. We aimed to compare the efficacy and safety of EMR-C and ESD for the treatment of small rectal NET.

Conditions

  • Rectal Neuroendocrine Tumor

Interventions

PROCEDURE

ESD procedure

ESD were all performed as the standard procedure that has been widely described and used. A diluted sodium hyaluronate solution was injected submucosally. Mucosal incision and submucosal dissection were performed by using either Hook knife (Olympus Medical, Japan) or a dual-knife (Olympus Medical, Japan) . After the resection was finished, all of the visible vessels on the artificial ulcer bed were thoroughly coagulated with argon plasma coagulation to prevent postoperative bleeding.

PROCEDURE

EMR-C procedure

A transparent cap (MH-593; Olympus) was attached to the forward-viewing endoscope. After the endoscope was inserted to the rectum, the snare passed through the sheath and was looped along the inner lip of the cap. The tumor was then suctioned into the cap and the snare was pushed off and closed. After confirming the appropriate snare placement, both the tumor and the overlying mucosa were resected by electric cautery (Endocut Q, effect 2, VIO 200D; ERBE, Tübingen, Germany), and then the removed tumor was sent for pathological examination. Endoscopic examination then was repeated without the transparent cap in order to evaluate the wound carefully in case there was any perforation or bleeding and to ensure the absence of the residual tumor tissues. If there was spurting bleeding or active bleeding, hot forceps were usually to stop the bleeding.
