Colonoscopic polypectomy using pure cut current is safe and effective, with bleeding rates comparable to other methods when hemoclips are readily available. Expertise in hemoclip placement is recommended for this technique.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery

Background:

  • Traditional recommendations for colonoscopic polypectomy favor coagulation or blended electrosurgical currents.
  • Pure cut current has been perceived to carry a higher risk of post-procedure bleeding.

Purpose of the Study:

  • To evaluate the incidence and characteristics of complications associated with colonoscopic polypectomy performed using pure cut current in a large patient cohort.

Main Methods:

  • A retrospective review of 9555 colonoscopic examinations was conducted.
  • Complications were analyzed for 4735 polypectomy cases exclusively using the cutting waveform of electrosurgical current.

Main Results:

  • Electrosurgical polypectomy with pure cut current resulted in a 1.1% hemorrhage rate.

  • Hemoclips were used in 12% of cases to prevent bleeding.
  • Delayed bleeding was more common in younger patients (50.5 years) compared to immediate bleeding (64.7 years).
  • No perforations occurred, with one case of transmural burn.

    • Conclusions:

    • Colonoscopic polypectomy using pure cut current can achieve bleeding rates comparable to coagulation or blended currents.
    • The successful application of hemoclips is crucial for managing bleeding risk with this technique.
    • Proficiency in hemoclip placement is advised for endoscopists utilizing pure cut current for polypectomy.
