NCT04548947

Brief Summary

This is a prospective, multi-endoscopist, single center, clinical study at tertiary referral center that addresses an important current challenge in the prevention of colorectal cancer (CRC), namely, how to improve the complete removal of CRC precursors. This study will observe the potential benefit of specific polypectomy technique in conjunction with a systematic submucosal injection prior to the polyp resection. This study will evaluate the completeness and incompleteness of the resection of colorectal neoplastic polyps during the procedures.

Outcome Measures

Primary Outcomes (1)

  • Incomplete resection rate (IRR)

    The number of incomplete polyps resected after polypectomy, as defined by any neoplastic tissue found in marginal biopsies.

    Day 1

Secondary Outcomes (5)

  • Immediate bleeding complications

    Day 1

  • Delayed bleeding complications

    14 days after the initial procedure

  • Other severe complications

    14 days after the initial procedure

  • Proportion of polyps considered interpretable for complete polyp removal

    14 days after the initial procedure

  • Incomplete resection of colorectal polyps

    14 days after the initial procedure

Study Arms (1)

Cold snare polypectomy with a submucosal injection

EXPERIMENTAL

The procedure will include a cold snare polypectomy with a submucosal injection done prior to the resection.

Procedure: Cold snare polypectomy in conjunction with a submucosal injection

Interventions

The cold snare polypectomy in conjunction with a submucosal injection is a procedure during which the endoscopist resects the colorectal polyps during a colonoscopy, without any electrocautery.
