NCT02484079

Brief Summary

This study aims to investigate the comparative effectiveness between polyp removal with or without electrical current. The investigators want to include 600 polyps in the trial. It is known that polyps have the potential to develop to cancer if left in situ, but the investigators do not know the best way to remove them completely.

Outcome Measures

Primary Outcomes (1)

  • Complete resection rate

    We want to measure the rate of polyps that are resected completely, both with biopsies from the margin and the histopathologists evaluation of the resection margins of the polyp itself.

    Hopefully within 4 weeks, when the histopathologist has examined the biopsies

Secondary Outcomes (5)

  • Complications

    4 weeks

  • Factors explaining the primary outcome

    During the hospital stay and up to 4 weeks.

  • Factors explaining the primary outcome

Study Arms (2)

Cold polypectomy

ACTIVE COMPARATOR

Patients in this arm will have their polyps removed by cold polypectomy, i.e. a metal sling that is closed around the basis of the polyp, and the polyp is cut off. After removal there will be taken biopsies from the resection margins, and both the polyp and the biopsies will be examined by a histopathologist to see if the polyp is removed completely.

Procedure: Polypectomy

Hot polypectomy

ACTIVE COMPARATOR

Patients in this arm will have their polyps removed by hot polypectomy, i.e. a metal sling taht is closed around the basis of the polyp, electrical currents is applied, and the polyp is cut off. After removal there will be taken biopsies from the resection margins, and both the polyp and the biopsies will be examined by a histopathologist to see if the polyp is removed completely.

Procedure: Polypectomy
