Hemorrhage after colonoscopic polypectomy is rare (0.2%) and typically resolves without surgery. Diagnostic imaging like technetium-tagged red blood cell scintigraphy aids in managing post-polypectomy bleeding.

Area of Science:

  • Gastroenterology
  • Endoscopic Procedures
  • Gastrointestinal Hemorrhage

Background:

  • Post-colonoscopic polypectomy hemorrhage is a potential complication.
  • Understanding its incidence and management is crucial for patient care.

Purpose of the Study:

  • To evaluate the incidence of hemorrhage after colonoscopic polypectomy.
  • To assess diagnostic methods for identifying bleeding sources.
  • To determine effective treatment strategies for post-polypectomy hemorrhage.

Main Methods:

  • Retrospective chart review of 12,058 patients undergoing colonoscopy.
  • Analysis of 6,365 patients who had polypectomies or biopsies.
  • Evaluation of diagnostic tools including scintigraphy and arteriography.

Main Results:

  • Hemorrhage occurred in 0.2% of patients (13/6365), with a mean onset of 8 days post-procedure.
  • Technetium-tagged red blood cell scintigraphy localized bleeding in 31% of cases.
  • Non-surgical interventions including vasopressin infusion and endoscopic electrocautery were effective in managing bleeding.

Conclusions:

  • Hemorrhage following colonoscopic polypectomy is infrequent and generally manageable without surgery.
  • Initial stabilization followed by diagnostic evaluation is recommended.
  • Nuclear scintigraphy is valuable for identifying active bleeding and guiding further invasive procedures.
