Summary

The aim of this study is evaluating and safety and efficacy between the modified double snare EMR and ESD. It is intended to prove that for rectal neuroendocrine tumors within 1 cm, the complete resection rate of the mDS-EMR is not inferior to that of ESD, but may with shorter operation time, lower complication rate and lower treatment cost.

Conditions

  • Rectal Neuroendocrine Tumors

Interventions

PROCEDURE

modified double snare assisted endoscopic mucosal resection

A polypectomy snare (resection snare) was placed outside of the endoscope. After approaching the lesion, a second polypectomy snare (capture snare) was inserted through the biopsy channel of the endoscope to grasp and lift the lesion. The snare preloaded outside of the endoscope was released, passed through the capture snare and positioned below the capture snare to grasp the base of the lesion. Once the lesion was securely grasped, it was resected by resection snare to achieve en bloc resection. The wounds were closed by clips.

PROCEDURE

endoscopic submucosal dissection

The procedure includes submucosal injection of normal saline and methylene blue suspension, cutting and dissection by mucosal incision knife (such as Dual knife, Golden knife or Kunpeng knife, etc.) , hemostasis and sealing of the wound. Traction is allowed during the operation.
