Colon perforation during colonoscopy is a rare but serious complication. While surgery is often necessary, conservative management can be successful in select cases with careful monitoring.
Area of Science:
- Gastroenterology
- Surgical Gastroenterology
- Endoscopy
Context:
- Colonoscopy is a widely used diagnostic and therapeutic tool.
- Colon perforation is a known, albeit infrequent, complication of colonoscopy.
- Understanding incidence and management is crucial for patient safety.
Purpose:
- To determine the incidence of colon perforations from colonoscopies.
- To evaluate the management strategies and outcomes of these perforations.
- To analyze factors influencing diagnosis and treatment.
Summary:
- A retrospective review of 16,285 colonoscopies identified 15 perforations (0.09%).
- Most perforations occurred during diagnostic procedures and were detected intra-procedurally.
- Delayed diagnosis occurred in 40% of cases, with surgery in 80% and a 25% mortality rate.
Impact:
- Highlights the rarity and potential severity of colon perforation.
- Suggests conservative management is viable for selected patients.
- Emphasizes that mortality is linked to patient status, not surgical technique.
