Evaluation of the efficacy and morbidity of radiofrequency thermocoagulation in the treatment of hemorrhoidal disease

Abstract

Introduction: Grade III hemorrhoidal disease may require surgical treatment. Several minimally invasive techniques can be offered to the patient, particularly ligation of the hemorrhoidal arteries/mucopexy or even stapled hemorrhoidopexy. A technique of radiofrequency thermocoagulation of hemorrhoids has recently been introduced. The aim of our study was to assess the efficacy and early morbidity of this procedure.

Methods: Data from successive patients undergoing radiofrequency thermocoagulation for grade II to IV hemorrhoidal disease between December 2017 and December 2019 were retrospectively collated.

Results: Seventy-four patients, with a mean age of 53 years, underwent operation during the study period. The major indication was grade III hemorrhoidal disease in 95% of patients. More than 80% of patients underwent operation as an outpatient. Eighteen (24.3%) patients developed a postoperative complication within 30 days, of whom two (2.7%) required revisional surgery for rectal bleeding and severe anal pain, respectively. Seven (9.5%) patients were re-admitted to hospital and 18 (24.3%) had an unscheduled early return visit within 30 postoperative days. At three months following surgery, the anatomical and functional result was satisfactory in more than 93% of patients.

Conclusion: Radiofrequency hemorrhoidal thermocoagulation is an effective technique in the treatment of grade III hemorrhoidal disease. Despite a non-negligible rate of minor postoperative complications requiring an early consultation or re-hospitalisation, severe complications occurred in less than 3% of operated patients.
