Summary
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.
