Objectives: Clinical and paraclinical findings of chronic radiation proctitis patients who received argon plasma coagulation and evaluate the efficacy of this technique. Subjects and methods: A cross – sectional descriptive study. We enrolled all the patiens who had proctitis after receiving radiotherapy to treat pelvic cancer and were treated with the Argon Plasma Coagulation method at the Gastroenterology and Hepatology Center, Bach Mai Hospital from September 2018 to October 2023. Results: The mean age of the patients was 62,7±10,7 years (32 – 85 years old), the disease occurred predominantly in women (90,6%). The time for symptoms to appear after radiotherapy were 3 years with a rate of 93,7%. All patients were admitted to the hospital because rectal bleeding, the rate of patients requiring blood transfusion was 39,1%. 100% of patients had abnomal rectal mucosa, the mean Zinicola score was 3,5±1,1 (2-5), wacher score ≥ 3 accounts for 65,7%. The procedure was successful in 100% of cases, the recurrence rate after 12 months was 34,4%. The most side effects were abdominal pain 20%, ulcer 15,4%, and stenosis 6,2%. Conclusion: Chronic radiation proctitis usually occurs within 3 years after receiving radiotherapy, all patients had abnormal rectal mucosa. APC is the safe and effective endoscopic hemostasis treatment. The most side effects were abdominal pain, ulcer, stenosis.
