OBJECTIVES: To evaluate endoscopic improvement after argon plasma coagulation (APC) in symptomatic patients with chronic radiation proctopathy.
METHODS AND PATIENTS: A prospective study of 38 patients with radiation proctitis (26 males and 12 females, mean age 70.9 +/- 7.38 yrs), and with rectal bleeding and or anemia. We performed monthly interviews, blood tests, and APC sessions until rectal bleeding had ceased and hemoglobin and ferritin levels were improved, with a follow-up of 24 months. We used blood testing, bleeding scores (Chutckhan's index), and endoscopic scores to evaluate improvement.
RESULTS: Mean time between inclusion and follow-up completion was 28.5 +/- 3.9 months. Mean number of sessions per patient was 3.6 +/- 2.7. There was a significant decrease (2.29 +/- 1.8 vs. 0.59 +/- 1.12, p < 0.05) in rectal bleeding (Chutckan score) from baseline after APC. There was a significant increase in hemoglobin levels (11.3 +/- 3.05 vs. 14.014 +/- 1.29, p < 0.001) and ferritin levels (31.15 +/- 66.45 vs. 80.60 +/- 55.6, p < 0.05) from baseline after APC. Also, there was improvement in the endoscopic index at the end of treatment, as well as in friability (p < 0.0001) and involved surface area (p < 0.0001).
CONCLUSION: Argon plasma coagulation is an effective technique, and the endoscopic index is a useful tool to evaluate endoscopic improvement.
