Brief summary: Hemorrhoidal artery ligation with Doppler guidance (HAL) and suture fixation of hemorrhoidal nodes (RAR) is a popular minimally invasive technique for hemorrhoidal disease (HD) treatment which uses an ultrasound probe to detect hemorrhoidal arteries for further ligation. We hypothesized that ultrasound guidance has no advantages over manual hemorrhoidal arteries detection for HD treatment.

The aim is to compare the results of HAL-RAR procedure in patients with stage II-III HD with Doppler and manual HA detection.

In this ongoing randomized, controlled, single center clinical study 200 patients randomly divided into group A (HAL-RAR with Doppler US navigation) and group B (HAL with manual HA detection and mucopexy) are planned to be included. The primary endpoint was recurrence of any symptoms of HD; secondary endpoints were pain syndrome severity (VAS), treatment satisfaction (1 to 5 points) and need for the drug therapy in 30 days and 8 weeks after surgery.

Ultrasound guidance technology of HAL with mucopexy could have the same efficacy the manual HA detection regarding the HD treatment effectiveness and patient satisfaction.

Detailed description: Hemorrhoidal disease (HD), in its different manifestations, is not only the most frequented grounds of referring for medical attention, but also one of the reasons for the modest deterioration in the quality of life that can possibly result in temporary or permanent reduction of work capacities. Today, the doppler-guided dearterialization of hemorrhoidal arteries and the following suture-fixation mucopexy in the anal canal (synonyms: mucopexy, hemorrhoids lifting, HAL-RAR) is one of the most popular and actively studied methods of the stage II - III hemorrhoidal disease surgical treatment. A number of publications raise an issue whether it is really necessary to use a doppler while the localization of the hemorrhoidal arteries is typical in the vast majority of the observations and can be easily determined on palpation.

The aim of the study is to compare the direct and long-term results of the II - III grade HD surgical treatment with the use of two techniques of the suture ligation of the hemorrhoidal arteries with mucopexy. One of these methods is classic and widely known HAL-RAR, the other one has a principal differ in no-using the doppler to find the arteries, the surgeon defines them on palpation.

The hypothesis of the study is that the digital detection of hemorrhoidal arteries pulsation followed by suture ligation and mucopexy may be no less effective in the treatment of grade II - III hemorrhoids than the use of a doppler guide.
