Summary

Patients on warfarin can safely undergo colonoscopy. While procedures like hot biopsy slightly increase bleeding risk, overall complications remain low, suggesting current management is effective.

Area of Science:

  • Gastroenterology
  • Cardiology
  • Internal Medicine

Background:

  • Warfarin (a common anticoagulant) management requires careful consideration during procedures like colonoscopy.
  • Assessing perioperative risks is crucial for patient safety.

Purpose of the Study:

  • To evaluate the safety and complication rates of perioperative warfarin management in patients undergoing colonoscopy.
  • To analyze bleeding risks associated with specific colonoscopic interventions.

Main Methods:

  • Retrospective review of 109 colonoscopies in 94 patients on warfarin.
  • Warfarin was stopped 3 days prior and restarted the day after the procedure.
  • Coagulation parameters (prothrombin time, international normalized ratio) were measured before colonoscopy.

Main Results:

  • A low hemorrhagic complication rate of 0.92% was observed.
  • 47% of patients underwent hot biopsy or snare polypectomy.
  • Therapeutic procedures showed a slightly elevated complication rate of 1.96%.

Conclusions:

  • Colonoscopy appears safe for patients on warfarin.
  • Hot biopsy and snare polypectomy procedures are associated with a minor increase in bleeding risk.
  • Further research is recommended to refine anticoagulation guidelines for colonoscopy.
