Hemorrhoid surgery & surgical treatments

Hemorrhoid surgery in the UK is an expanding field with increasing diversity. If other treatments haven’t worked or your hemorrhoids are not suitable for non-surgical procedures, then surgery for hemorrhoids may be an option. There are a number of procedures available, but the main ones are set out below.

What is hemorrhoid surgery?

In short, these treatments involve the assistance of a surgeon, usually to physically remove the offending hemorrhoid(s). Hemorrhoid surgery is almost always done under anaesthesia.  Surgical procedures are likely to remove most hemorrhoids. Balanced against this is the potential discomfort and invasive nature of such treatments.

How long does hemorrhoid surgery take?

This varies depending on the type of hemorrhoid surgery which you choose to undertake. Other questions such as “how long does it take to recover from hemorrhoid surgery?” and “what should I expect after hemorrhoid surgery” fall into this same boat. The type of surgery which you undergo as well as the type and size (or grade) of your piles both have a bearing on the answer. Read on to learn more.

What are the risks of any hemorrhoid surgery?

The risk of any serious problems is small, but complications are not unheard of. These can include:

  • Bleeding or passing of blood clots after the operation leading to either delayed discharge or readmission following discharge, depending on the timing of the bleed
  • Unsatisfactory pain control
  • Post-operative nausea and vomiting
  • Infections that can lead to an abscess – usually treated with antibiotics or, in some cases, further surgery.
  • Difficulty in emptying your bladder (urinary retention)
  • Involuntary passing of gas or stools (gas or faecal incontinence)
  • A small anal fistula – a channel that develops between the anal canal and the skin near the anus.

There are other risks as well, including strictures, the need for a colostomy, etc. (some particular ones associated with stapling are mentioned below.)

All of the above are treatable but we’d advise talking to your surgeon who will be able to explain the risks in more detail.


What is involved with the operation?

A haemorrhoidectomy is carried out under a general (or spinal) anaesthetic. The operation involves opening the anus so that the hemorrhoids can be cut out. The operation is usually carried out under general anaesthetic and you will need to take at least a week or two off work to recover. There are variations on the actual technique used in terms of the cutting instruments employed for hemorrhoid surgery, and afterwards in either closing the resultant wounds using stitches or leaving the wounds open to heal naturally.

After the operation

Patients will experience variable amounts of pain during the initial hemorrhoid surgery recovery period, but your medical team should supply you with strong pain killers to help this. After hemorrhoid surgery, you may be in some level of discomfort for a few weeks, but this residual pain can usually be controlled with milder over the counter pain killers.

Transanal doppler-guided hemorrhoidal artery ligation.

What is involved with the operation?

This hemorrhoid surgery is designed to reduce the blood flow to your hemorrhoid(s). It is usually carried out under a general (or spinal) anaesthetic and involves a small ultrasound probe being inserted into your anus, which creates high frequency sound waves allowing the surgeon to locate any blood vessels that are supplying blood to the hemorrhoid so that they can be targeted. Once the blood vessels feeding into the hemorrhoid are located, a needle and surgical thread is used to stitch them closed, to cut off the blood supply to the hemorrhoid, causing it to shrink. Other hemorrhoids present are similarly targeted.

After the operation

The National Institute of Health and Care Excellence (NICE) recommends this procedure as an alternative to hemorrhoidectomy or stapled hemorrhoidopexy as it causes less pain and recovery time is improved. There is a low risk of bleeding when passing stools and of the hemorrhoid prolapsing. A systemic review of this treatment revealed pain relief being needed in 0-38% of patients, bleeding postoperatively in 5% and an overall reintervention rate of 6.4%.

NICE evaluation

Stapling – Hemorrhoidopexy.

What is involved with the operation?

This procedure is carried out under a general (or spinal) anaesthetic to treat prolapsing or prolapsed hemorrhoids. The treatment itself involves removing a section of the large intestine and stapling the ends back together. This results in the hemorrhoids being less likely to prolapse. It also reduces the supply of blood to the hemorrhoid, causing it to shrink.

After the operation

It has a shorter recovery time than a conventional hemorrhoidectomy and on average you can return to work after a week. It also tends to be a less painful experience.

But, it is reported that more people experience another prolapsed hemorrhoid after this operation compared to alternative surgical hemorrhoid procedures. Other complications include severe pain, and an increased risk of a stricture (a tightening of the anal canal) developing, as well as bleeding, skin tags, hemorrhoidal thrombosis, faecal urgency, gas and faecal incontinence.

In addition to the various complications listed above, rare but potentially life-threatening complications have also been described, including anovaginal fistula (a connection between the anal canal and the vagina), anastomotic leakage with associated pelvic sepsis (the stapling line leaking bowel contents into the pelvis leading to infection), and Fournier’s gangrene (tissue death in the groin and perianal area).
