How can (DG) HAL/RAR® help me?

A product of A.M.I. (Agency for Medical Innovations) is the (DG) HAL/RAR® System. It is the first system to utilize minimally invasive surgical techniques to treat the source of hemorrhoidal disease without surgical excision, stapling or banding. It is a single system that offers two procedure options, (DG) HAL (Doppler Guided Hemorrhoidal Artery Ligation) and (DG) RAR (Doppler Guided Recto Anal Repair Proctoplasty).

How many patients have been treated and what are the results?

Available to patients since 2001, the procedures have been successfully performed on tens of thousands of patients worldwide. Physicians report an institutional success rate of 93-96% in treating patients with grades II to IV disease. Complication rates are very low, and any complications that do occur, such as minor bleeding, thrombosis, and defecation pain, are very manageable.

top

How long does the procedure take, will I be hospitalized, and when can I go back to work?

The procedure can take as little as twenty minutes and patients usually leave the same day. Most patients experience only minor pain and discomfort, and return to work the next day.

top

What kind of care will I need before, during, and after the procedure? What medications will the doctor prescribe?

Discuss this in-depth with your physician as your age, weight, and physical condition will influence how you are medicated and managed during and after the procedure. Your surgeon may opt to forgo general anesthesia for conscious sedation. Again, you should discuss these options with your doctor. Results are variable but post-procedural pain medications are usually minimal and for limited duration.

A.M.I. HAL Method

The HAL Method - Doppler Guided Hemorrhoidal Artery Ligation Procedure

1. The patient is positioned in Lateral Recumbent or in a Lithotomy Position.

2. Ultra Sound Gel is put on the A.M.I. HAL-Doppler Proctoscope before it is fully trans-anally inserted and slowly/gently turned until a typical Doppler sound of arterial blood flow can be heard.

3. The identified arteries are ligated in a distance 3 to 4 cm proximal to the Dentate Line through the ligation window of the A.M.I. HAL-Doppler Proctoscope, thus reducing the blood inflow to the inner hemorrhoidal plexus.

Good control

  • Rapid identification of terminal branches of superior hemorrhoidal artery
  • Precise, accurate ligation
  • Immediate confirmation
  • Minimum discomfort
  • Minimally invasive surgery
  • Ligation sutures are placed 2-3 cm above dentate line
  • General or MAC (Monitored Anesthesia Care) sedation
  • High success rate
  • 90% or greater success rate
  • No major complications reported
  • Ratio of inflow to outflow drops significantly

A.M.I. RAR Method

The (DG) RAR Method – Doppler Guided Recto Anal Repair Proctoplasty (Mucopexy) Procedure

1. First, a running stitch is made from the top to the bottom. The device is so designed that only the prolapsing tissue is caught by the needle.

2. The ends of the thread are pulled together and knotted at the top. This has the effect of lifting up the hemorrhoids that are hanging down.

3. With this “lifting”, the hemorrhoids are back where they belong. The tissue scars over and integrates “seamlessly” back into the anal tissue. The stitches are placed not in the anus but in the lower rectum, where there are almost no pain nerves. Patients report little discomfort or pain associated with these procedures.

Patient Satisfaction
  • “93.75% of patients would recommend treatment with (DG) HAL/RAR® to a friend because of the level of pain and effectiveness”
  • “91% of patients would ask for HAL treatment if necessary”
  • Recovery normally takes just one to three days

HAL / RAR – A Combination of Doppler-Guided Hemorrhoidal Artery Ligation and Transanal Rectal Mucopexy for the Treatment of all Stages of Hemorrhoidal Disease with the Hemorrhoidal Treatment System
Bludenz State Hospital (LKH), Department of General Surgery Hemorrhoidal disease is one of the most common diseases of the anal region. Ten percent of patients require surgical intervention. At our department, we have performed hemorrhoidal artery ligation (HAL) since 2000 and have further refined the technique of Doppler ultrasound-guided recto-anal repair (RAR), the combination of HAL and transanal rectal mucopexy (TRM). From January 2000 to July 2006, we applied HAL in 656 patients. Our results show that HAL can be performed successfully and with high patient comfort in patients with grade 2, grade 3, and grade 4 hemorrhoidal disease. Merely the recurrence rate for prolapse (13%) in grade 3 patients and a far too high rate of prolapse recurrence (almost 60%) in grade 4 patients were not satisfactory. Based on our own experience and references in the literature, we developed RAR, a combination of Doppler-guided HAL and TRM. A proctoscope, specially designed for this purpose (HTS Hemorrhoidal Treatment System), enables the standardized application of HAL and the use of continuous sutures for narrowing the prolapse. The Doppler-guided HAL leads to a reduction of the blood flow and a shrinking of existent hemorrhoidal cushions, while TRM leads to a lifting of the prolapse. On the whole, this standardized technique allows for the restoration of the normal anatomy using minimally invasive surgery with substantially reduced patient pain and discomfort. We report our first 110 cases treated with Doppler-guided RAR. The results show that with this new technique we can refer to a minimally invasive procedure for the treatment of all stages of hemorrhoidal disease that achieves high patient satisfaction and has a success rate of over 90%.

Treatment of Grade 2 and 3 Hemorrhoids with Doppler-Guided Hemorrhoidal Artery Ligation
Abstract
Aim: We evaluated the results of the Doppler-guides hemorrhoidal arterial ligation (DG-HAL) method in the management of symptomatic grade 2 and 3 hemorrhoids.
Patients and Methods:
Between June 2005 and March 2006, 110 consecutive patients with symptomatic grade 2 and 3 hemorrhoids according to the DG-HAL method were treated. All procedures were preformed in daycare under spinal anaesthesia. The primary objective was the reduction in hemorrhoidal gradation as determined by proctscopy; the secondary was patient satisfaction This was measured by interviewing patients over the telephone. Results: The average age as 47,6 years. 42 patients had grade 2 hemorrhoids, 58 grade 2. An average of 7.3 ligations were placed. Proctoscopy showed that, after 6 weeks, 97 (88%) patients had a significant improvement in their hemorrhoidal gradation. After an average follow-up of 37 weeks, 93 of the 110 (84,5%) patients ware satisfied with the postoperative result. Mortality was 0% and morbidity 3%.
Conclusion: DG-HAL is a safe and effective treatment in the management of symptomatic grade 2 and 3 hemorrhoids.

Stapled transanal rectal mucosectomy ten years after Tech Coloproctol 2007
Stapled mucosectomy (SM) was first proposed for the management of patients with rectal internal mucosal prolapse and obstructed defecation, but gained popularity worldwide for the treatment of hemorrhoids. The present review highlights the advantages and disadvantages of the operation. SM tends to decrease postoperative pain and shortens convalescence after hemorrhoid surgery, but may be followed by severe complications, e.g. rectal obliteration and pelvic sepsis requiring a diverting stoma, more frequently than after standard hemorrhoidectomy. Moreover it carries a higher recurrence rate in the treatment of fourth-degree piles. A recent Cochrane metaanalysis demonstrated that SM is less effective than standard hemorrhoidectomy since it carries a higher recurrence rate (OR=3.6) and reintervention rate (OR=2.3). When used for rectal mucosal prolapse and obstructed defecation, SM is reported to have variable results. A better outcome is likely to be achieved in patients without anismus and psychoneurosis operated on by specialists trained with this technique.

Doppler-guides hemorrhoidal artery ligation.
Excerpta Medica – The American Journal of Surgery, 2006
Background: In 1995, Morinaga reported a new technique for the treatment of hemorrhoids, hemorrhoidal artery ligation (HAL), which uses a specially designed proctoscope coupled with a Doppler transducer for identification and ligation of hemorrhoidal arteries.
Methods: Because the arteries carrying the blood inflow are ligated, internal pressure of theplexus hemorrhoidalis is decreased.
Results: We report the results of the first 308 patients (189 male and 119 female; median age 50.1 years) who have been treated at our department since 2002 and followed-up for a median period of 18 months. Eighty-nine patients had grade II, 192 patients had grade III, and 27 patients had grade IV hemorrhoids. The acute symptoms of hemorrhoids were treated immediately by performing HAL.
Conclusions: Our study showed the HAL is painless, effective and has a low rate of complications. It can be applied on a outpatient setting and is on good alternative to all other haemorrhoid treatment methods.

The surgical Management of Haemorrhoids - A Review
A number of new surgical treatments have led to a reappraisal of haemorrhoid disease over the last few decades. Despite a range of treatment modalities, the options are limited in their effectiveness and can lead to a number of complications. An inadequate classification system based on appearance rather than symptoms makes the choice of appropirate therapy difficult. More recent techniques have led to a move away from surgical excision. However, further research is required to establish their precise indications and long-term efficacy.

Values of clinical application of Doppler-guided hemorrhoid artery ligation (Dg-HAL) in treatment of hemorrhoids (a report of 40 cases) General Surgery Department of PLA General Hospital (Bejinig)
The objective of this article was to evaluate the efficacy of procedure for Doppler-guided hemorrhoid artery ligation DG|HAL in treatment of hemorrhoids. The 40 patients with the symptomatic hemorrhoids underwent a DG/HAL. The mean operation time was 26.5minutes and postoperative hospital stay was 1.15 days; the time of returning to work was 2.15 days and 94.2% of patients were satisfied with the results. There were no recurrence , and no faecal incontinence after short-up (2 weeks-3 months). Results show that DG/HAL for symptomatic hemorrhoids is a safe procedure with good results, low complications ,shorter hospital stay and earlier recovery. Doppler-guided hemorrhoid artery ligation seems to be ideal for 1-day surgery, and it fulfills the requirements of minimally invasive surgery. But long-term effect is to be investigated.
