THD and HALO Treatment for Haemorrhoids

Transanal haemorrhoid dearterialization (THD) or haemorrhoidal artery ligation operation (HALO) are minimally invasive surgical procedures for treating haemorrhoids/piles.

Haemorrhoids are lumps caused by swollen veins that are located inside and around your anus. Many haemorrhoids get better on their own, but if you have haemorrhoids that are not improving after lifestyle changes and homecare then you should seek medical guidance to help relieve you of troubling symptoms.

Minimally Invasive Haemorrhoid Treatment

When searching for haemorrhoid treatment, there is a wide variety of techniques available and many patients are keen to choose one that promotes a quick recovery time like THD or HALO.

Also known as doppler guided ligation, haemorrhoid ligation or haemorrhoidal artery ligation, THD is an innovative surgical treatment that is designed to cure haemorrhoids in a minimally invasive way. The procedure has been approved by the National Institute for Clinical Excellence (NICE) in 2010 as an effective alternative to haemorrhoidectomy or stapled haemorrhoidopexy.

The procedure uses a micro- doppler ultrasound device to guide the to place a suture across the arteries. Haemorrhoidal blood supply to the haemorrhoids so by these, the haemorrhoids should shrink.

What is a HALO treatment for piles and how does it differ from a THD procedure?

Haemorrhoidal Artery Ligation Operation more commonly known as HALO is an almost identical procedure to THD. The main difference between the two is that the name is based on the company that supplied the disposable with an embedded Doppler ultrasound that the surgeon will use to perform the procedure.

At The Private Clinic, we use a THD doppler and will therefore predominately refer to the procedure as THD Treatment for Haemorrhoids.

What to Expect

A consultation will take place with one of our colorectal surgeons who are experts in haemorrhoids. Your surgeon will:

You will then meet with your dedicated coordinator who will provide you with a detailed treatment plan with full cost and pricing so you can leave feeling well-informed and able to decide if to go ahead with treatment or not.

In the interests of patient safety, all our patients are assessed against our patient criteria. Following your haemorrhoid treatment consultation and review of your past medical history, the physician or pre-operative nurse will decide if any pre-operative tests are required ahead of your procedure. If considered to be appropriate, these may routine blood tests.

You will be provided with a pre-operative instruction sheet ahead of your procedure which will help you to prepare for your haemorrhoid treatment.

Transanal haemorrhoid dearterialization is performed under general anaesthetic and takes around minutes to complete.

The treatment is known as being invasive as it does not require cutting any tissue which means there will be no raw or open wounds to heal . The procedure is performed in an area of the rectum that sits above the anal canal. This area has very few nerve and little sensation there is very little risk of pain in the area being felt after the procedure.

Following your THD procedure, you will be closely monitored in hospital for a short time before being discharged the same day by your surgeon once they are happy with your recovery. The rest of your recovery period will be carried out at home.

THD / Halo procedure for haemorrhoids recovery time

Overall, THD does have a shorter recovery period in comparison to a haemorrhoidectomy procedure. Most patients can return to their usual daily activities after 1 week.

Medication

A course of medication painkillers will be provided to patients following the procedure to help them feel comfortable.

Bathing

Showering and bathing can be resumed 24 hours post procedure. Sitz baths may be recommended for the first two weeks to help keep the area clean, especially after bowel movements.  

What is a sitz bath?

A sitz bath is a warm shallow bath of usually around 2-3 inches of water. It can take place in a bathtub or designated kits can be purchased that sit over a toilet. The bath should be sat in for minutes. Add any bath salts, oil or other to the bath should be avoided unless advised to by your surgeon. Once out of the bath, the bathed area should be patted dry with a warm towel and the water in the bath disposed of. You may be recommended to have multiple sitz baths a day to keep the area clean whilst also providing relief from any pain or discomfort following bowel movements.

Return to work

We recommend that patients allow 1 week off work, however this will depend on the requirements of your job role. Your surgeon will be able to advise further on this, but overall you should be comfortable and feel confident that you are able to fulfil your duties.  

Exercise

Excessive physical exertion or straining should be avoided for 1-2 weeks following THD treatment for haemorrhoids. Light physical exercise such as walking can be a few days following your procedure.

Driving

Driving should be avoided for at least 24 hours but overall, it is best advised not to drive whilst on painkiller medication. We would recommend letting your insurance company know of your circumstances as you may not be covered for a certain period of time following surgery. When you return to driving you should have full control of the car and be able to perform an emergency stop comfortably.

Lifestyle

We recommend that patients maintain a high-fibre diet and stay well-hydrated at all times to avoid painful bowel movements caused by constipation during recovery.
