Summary

A prospective randomised controlled trial of cold vs hot snare polypectomy of non-pedunculated colorectal adenomas.

Conditions

  • Colorectal Polyp

Interventions

PROCEDURE

Cold snare polypectomy

After a target polyp was identified, it should be placed at the comfortable position. Then the snare will be opened and encircled the polyp without air aspiration. Then, the snare will be captured the polyp with at least 1-2 mm of surrounding normal tissue. The polyp will be guillotined and would not be lifted or tented until complete closure is achieved. After resection, the mucosal defect the marginal mucosa was carefully observed, with used of magnification and image enhancement. If residual polyp tissue was recognised, additional removal using the cold snare technique or biopsy forceps will be performed. If a submucosal injection prior to snaring was necessary it will be permitted. After polypectomy all patients will be observed for 3-4 days in-hospital

PROCEDURE

Hot snare polypectomy

After a target polyp was identified, it should be placed at the comfortable position. Then the polyp with minimal normal tissue will be captured by the snare. The ensnared polyp should be tented away from the colonic wall and removed by one the types of electric currents. After resection, the mucosal defect will be washed thoroughly and the marginal mucosa was carefully observed, with used of magnification and image enhancement, such as near focus imaging or narrow band imaging. If a submucosal injection prior to snaring was necessary it would be permitted. If residual polyp tissue was recognised, additional removal using coagulation or biopsy forceps will be performed. After polypectomy all patients will be observed for 3-4 days in-hospital
