Abstract

Background: The transanal hemorrhoidal dearterialization (THD) Doppler procedure is a minimally invasive technique to treat symptomatic hemorrhoids. The aim of the study was to assess the clinical efficacy and the satisfaction of patients in a large series treated with THD and to review the relevant literature.

Methods: In this retrospective, single-institution, study consecutive patients with grade 2, 3, or 4 hemorrhoidal disease were treated with the THD Doppler procedure. Dearterialization was performed in all cases and mucopexy in case of prolapse. The dearterialization procedure evolved from "proximal artery ligation" to "distal Doppler-guided dearterialization." Follow-up was scheduled at 15 days, 1, 3, 12 months, and once a year thereafter. Complications were recorded. Clinical efficacy was assessed comparing both frequency of symptoms and disease grading (Goligher's classification) at baseline versus last follow-up. Uni-/multivariate analysis evaluated factors affecting the outcome.

Results: There were 1000 patients (619 men; mean age: 48.6 years, range 19-88 years). Acute postoperative bleeding was observed in 14 patients (1.4%), pain/tenesmus in 31 patients (3.1%), and urinary retention in 23 patients (2.3%). At mean follow-up duration of 44 ± 29 months, the symptomatic recurrence rate was 9.5% (95 patients; bleeding in 12 (1.2%), prolapse in 46 (4.6%), and bleeding and prolapse in 37 (3.7%) patients). The recurrence rate was 8.5, 8.7, and 18.1% in patients with grade 2, 3, and 4 hemorrhoids, respectively. Seventy out of 95 patients with recurrence needed surgery (reoperation rate: 7.0%). At final follow-up and taking into account the reoperations, 95.7% of patients had no hemorrhoidal disease on examination. Younger age, grade 4 disease, and high artery ligation affected the outcome negatively.

Conclusions: Our results show that the THD Doppler procedure is safe and effective in patients with hemorrhoidal disease and associated with low morbidity and recurrence rates and a high rate percentage of treatment success.
