A new technique of doppler dearterialization for hemorrhoidal disease: arterial detection ligation (ADL)

Abstract

We describe the arterial detection ligation (ADL) technique, designed to find arteries at time-appropriate depth for ligating, and report our preliminary results of using this technique to treat patients with the hemorrhoidal disease (HD). The subjects of this retrospective analysis were patients with symptomatic grades 2 or 3 HD. We analyzed the clinical characteristics, postoperative complications, recurrence, and patient satisfaction of the patients treated with ADL. A total of 75 patients were included in the study (male/female ratio 1.88; mean age 48 ± 19years; mean BMI 24 ± 3kg/m2). Thirty-nine patients (52%) did not require hospitalization and were discharged from the day clinic approximately 4h postoperatively. Four patients (5.3%) suffered tenesmus for about 1week postoperatively and two (2.7%) suffered temporary rectal bleeding. The mean VAS scores 1day postoperatively, then at 1week, 1month and 1year were 2.9, 1.5, 0.4, and 0, respectively. At the 1-month follow-up, there was no sign of recurrence and the satisfaction rate was 78.6% (n = 59). At the 1-year follow-up, three patients (4%) had a recurrence and the satisfaction rate was 86.7% (n = 65). Based on our preliminary findings, ADL is an effective technique for treating HD, generally as an outpatient procedure, without serious morbidity. We anticipate that the incidence of tenesmus, which is encountered frequently after other dearterialization methods, will be lower after the ADL technique, which avoids both mass ligation of hemorrhoidal arteries deeper than 12mm and running a long mucopexy suture line.
