Summary
Colonoscopy can cause rare but serious complications like superior rectal artery injury leading to bleeding. Prompt diagnosis and intervention, including embolization, are crucial for patient recovery.
Area of Science:
- Gastroenterology
- Interventional Radiology
- Surgical Oncology
Background:
- Colonoscopy is a widely used diagnostic and management tool for colon lesions worldwide.
- Complications following colonoscopy, though not frequent, are a recognized concern.
Purpose of the Study:
- To report a rare case of massive hemoperitoneum following colonoscopy.
- To highlight the diagnostic and management challenges of post-colonoscopy arterial injury.
Main Methods:
- A 79-year-old male patient presented with intraperitoneal bleeding post-colonoscopy.
- Diagnostic imaging included computed tomography (CT) and angiography to identify the bleeding source.
- Interventional management involved embolization of the injured right superior rectal artery followed by surgical intervention.
Main Results:
- The patient experienced massive hemoperitoneum due to injury of the right superior rectal artery.
- Angiography successfully identified the bleeding vessel.
- Embolization and subsequent operation effectively managed the hemorrhage.
Conclusions:
- This case represents the second reported instance of mesentery tear post-colonoscopy and the first with massive hemoperitoneum.
- Early identification and meticulous evaluation are critical for successful diagnosis and treatment of rare post-colonoscopy complications.
