Summary
Radiofrequency ablation (RFA) effectively controlled rectal bleeding in chronic radiation proctitis (CRP) patients. This minimally invasive treatment demonstrated safety and efficacy in a small case series, warranting further investigation.
Area of Science:
- Gastroenterology
- Oncology
- Radiation Therapy
Background:
- Chronic radiation proctitis (CRP) affects up to 20% of patients post-pelvic radiotherapy.
- Rectal bleeding is the primary symptom of CRP.
- Radiofrequency ablation (RFA) is a novel treatment option for gastrointestinal conditions.
Purpose of the Study:
- To evaluate the efficacy and safety of RFA for treating CRP.
- To describe the outcomes of four patients with CRP managed using RFA.
Main Methods:
- RFA procedures were performed using HALO 90 or HALO 90 Ultra ablation catheters.
- Treatments were delivered via a standard flexible endoscope.
- Symptom severity was assessed before and after RFA sessions.
Main Results:
- Complete symptom control was achieved in all patients.
- An average of two RFA sessions (range: 2-4) at three-month intervals were required.
- No major complications were reported during or after the procedures.
Conclusions:
- RFA is a safe and effective treatment for controlling rectal bleeding in CRP.
- Further randomized controlled trials are necessary to confirm the long-term safety and efficacy of RFA for CRP.
