PURPOSE Transanal hemorrhoidal dearterialization is an innovative technique to treat hemorrhoids using a specially designed proctoscope for Doppler-guided transanal ligation of hemorrhoidal arteries. We analyzed results of experience at a single-institution with this transanal hemorrhoidal dearterialization device. METHODS Overall, 170 patients were submitted to transanal hemorrhoidal dearterialization during the period July 2005 through October 2008. The operation consisted of hemorrhoidal dearterialization (of 6 arteries) in all patients, with major mucosal/submucosal pexy in 56 patients (32.9%). The first consecutive 11 patients (6.4%) were treated under general/spinal anesthesia, the remaining 159 (93.6%) by sedation with propofol, supported by analgesia with remifentanil. Following transanal hemorrhoidal dearterialization surgery, patients were regularly evaluated at 2 weeks, 1 and 3 months, and once a year after operation. RESULTS The mean age of the 170 patients was 47.3 +/- 13.0 years; 102 (60%) were men. Hemorrhoidal disease was grade II in 13 (7.6%); grade III in 141 (82.7%), and grade IV in 16 (9.6%). Postoperative bleeding requiring surgical hemostasis occurred in 2 cases (1.2%). Mean follow-up was 11.5 +/- 12 (range, 1-41) months. Hemorrhoidal thrombosis occurred in 4 patients (2.3%), chronic pain and fecal incontinence in none. Hemorrhoidal prolapse was reported at follow-up by 50 patients (29.5%), but prolapse was confirmed only in 18 (10.5%) and was mild; some patients reporting prolapse were found to have skin tags. Overall, long-term control of bleeding was obtained in 159 patients (93.5%) and control of prolapse in 152 (89.5%). Recurrence of hemorrhoidal disease requiring surgery was found in 7 patients (4.1%). CONCLUSIONS Transanal hemorrhoidal dearterialization appears to be a very effective minimally invasive option to treat hemorrhoids and can be performed in a day-surgery setting. Future controlled trials comparing transanal hemorrhoidal dearterialization with other procedures will show the real potential of transanal hemorrhoidal dearterialization and define adequate indications for this approach.

Perianal abscess following doppler-guided transanal hemorrhoidal dearterialization

The doppler-guided transanal hemorrhoidal dearterialization (DGTHD) is a well-established and validated minimally invasive procedure for the treatment of symptomatic hemorrhoids. As compared to the excisional technique, DG-THD has the advantage of being associated with less post-operative pain and do not compromise the anatomy or the physiology of the anal canal. Our objectif is to describe the...

A randomized trial of transanal hemorrhoidal dearterialization with anopexy compared with open hemorrhoidectomy in the treatment of hemorrhoids.

BACKGROUND Doppler guidance in hemorrhoidal surgery has become more frequent during the past decade. The method is mainly studied in nonrandomized trials. Data from randomized controlled trials are lacking. OBJECTIVE The aim of this study was to compare early and midterm results of transanal hemorrhoidal dearterialization with anopexy to open hemorrhoidectomy. DESIGN, SETTINGS, PATIENTS, AND ...

Brain Abscess after Transanal Hemorrhoidal Dearterialization: A Case Report

A relatively new therapy in the treatment of hemorrhoids is transanal hemorrhoidal dearterialization (THD). We report a case of brain abscess caused by Streptococcus milleri following THD. Although a brain abscess after drainage of a perianal abscess has been described in the literature, no report exists of a brain abscess following treatment of hemorrhoids. A healthy 51-year-old man with hemor...

The current patho-physiologies of hemorrhoids include the degenerative change of supportive tissue within the anal cushions, vascular hyperplasia, and hyper perfusion of the hemorrhoidal plexus. On the one hand hemorrhoidectomy has been the mainstay of surgical treatment, while more recently other approaches have been employed including stapled hemorrhoidopexy and Dopplerguided hemorrhoidal art...
