Summary
Radiation-induced solitary rectal ulcers can cause severe lower intestinal bleeding. This case highlights embolization and surgical resection as potential treatments for massive hemorrhage from rectal ulcers involving arteries.
Area of Science:
- Gastroenterology
- Vascular Surgery
- Radiation Oncology
Background:
- Solitary rectal ulcer syndrome (SRUS) is a rare condition.
- Radiation therapy can induce rectal injury, including solitary ulcers.
- Hemorrhage is a potential complication of rectal ulcers.
Observation:
- A patient presented with radiation-induced solitary rectal ulcer.
- The ulcer was unusually located posteriorly, involving the internal iliac artery.
- This led to massive lower intestinal hemorrhage.
Findings:
- Percutaneous arterial catheter embolization provided temporary hemorrhage control.
- Surgical resection was required for definitive management of the massive bleeding.
Implications:
- This case highlights a rare but severe complication of radiation therapy.
- It underscores the importance of considering vascular involvement in rectal bleeding.
- Multidisciplinary management involving interventional radiology and surgery is crucial for such cases.
