Summary
Radiofrequency ablation (RFA) offers a safe and effective treatment for chronic radiation proctitis, successfully reducing bleeding and achieving transfusion independence in patients. This approach shows promise as an alternative to existing therapies.
Area of Science:
- Gastroenterology
- Oncology
- Medical Devices
Background:
- Chronic radiation proctitis is a debilitating condition following pelvic radiation therapy for malignancies.
- Current treatments like argon plasma coagulation (APC) have limitations, including ulceration and stricture complications.
- Radiofrequency ablation (RFA) is emerging as a potential alternative, particularly for transfusion-dependent patients.
Observation:
- Two cases of chronic radiation proctitis, including one transfusion-dependent patient, were treated with focal RFA.
- Significant reduction in haematochezia was observed the day after treatment.
- Transfusion independence was achieved after a single RFA session.
Findings:
- Focal RFA demonstrated safety and efficacy in treating chronic radiation proctitis.
- Neovascular lesions required three to four RFA sessions for eradication.
- Successful rectal re-epithelialisation and sustained absence of bleeding up to nine months post-treatment were noted.
Implications:
- RFA presents a viable and potentially superior alternative to APC for managing radiation-induced proctitis.
- The technique offers a promising solution for transfusion-dependent patients, improving quality of life.
- Further research into RFA for radiation proctitis is warranted to confirm these findings in larger cohorts.
