Modern haemorrhoid procedures: HAL/RAR, laser and stapled (PPH) explained

If your doctor has told you that your piles need more than creams and lifestyle changes, the good news is that haemorrhoid surgery has moved a long way from the older “cut it out” operation many people still fear. Today there are several tissue-sparing options that aim for the same result — comfortable, bleed-free bottoms — with far less post-operative pain and a quicker return to work.

This guide walks through the three most useful modern options Dr Pieter Marais offers in Johannesburg: HAL/RAR (Doppler-guided haemorrhoidal artery ligation with recto-anal repair), laser haemorrhoidoplasty, and PPH (stapled haemorrhoidopexy). If you are still working out whether you actually have piles, our plain-language piles guide and the haemorrhoids service page are the right places to start.

Why “modern” matters

The classic operation for piles — an excisional haemorrhoidectomy or " classical milligan morgan" — works extremely well, but it involves cutting tissue below the dentate line, the part of the anal canal that has pain-sensitive nerves. That is why recovery has a reputation for being sore. The newer procedures share one core idea: treat the piles from above the pain-sensitive line, or shrink them from the inside, so the wound area is smaller and the nerves are largely left alone. For most patients that translates into less pain, less time off work and a faster return to normal life.

None of these procedures is a magic wand. They suit specific grades of piles and specific patients — which is why the consultation and examination matter as much as the technology.

A quick recap: when is surgery considered?

Haemorrhoids are cushions of blood vessels inside the anal canal that everyone has. They become a problem when they enlarge, bleed, prolapse (come out) or thrombose (clot painfully). Doctors grade internal piles I to IV based on how far they prolapse:

Grade I — bleed but don’t come out.
Grade II — prolapse on straining but slip back in on their own.
Grade III — prolapse and need to be pushed back in.
Grade IV — stay prolapsed all the time.

Surgery is generally considered when fibre, hydration, topical treatments and office-based procedures haven’t settled things, or when the grade is already too high for those to work.

HAL/RAR — Doppler-guided artery ligation with mucopexy

HAL/RAR is often the first “modern” option we discuss for symptomatic grade II and grade III piles, especially where prolapse is a big part of the problem.

What actually happens: a small probe with a tiny Doppler ultrasound sensor is inserted into the anal canal. The Doppler beeps when it finds the small arteries that are feeding the pile cushions. A stitch is placed around each artery to tie it off (ligation) — this cuts the blood supply so the piles shrink over the following weeks. In the same sitting, extra stitches are used to lift and gather up any prolapsing lining back into its normal position — that’s the “RAR” (recto-anal repair, also called mucopexy).

Why it’s comfortable: everything is done above the dentate line, so the pain-sensitive skin is not cut.

Who it suits: mainly grade II and grade III piles, particularly bleeders with prolapse.

Recovery snapshot: general or spinal anaesthetic, day case, most patients back at desk work within 3–5 days. Some fullness and mild discomfort with the first few bowel motions is normal.

Laser haemorrhoidoplasty (LHP)

Laser haemorrhoidoplasty shrinks the pile from the inside using a fine laser fibre.

What actually happens: through a tiny opening, a laser fibre is passed into the body of the pile. Controlled pulses of laser energy heat the tissue from within, collapsing the enlarged vessels and shrinking the cushion. There is no large external wound and, in most cases, no stitches on the sensitive skin.

Why it’s comfortable: the energy is delivered inside the pile, sparing the anal skin and dentate line.

Who it suits: grade II and selected grade III piles, particularly patients whose main complaint is bleeding and swelling rather than significant prolapse. It can be combined with a mucopexy when there is prolapse to address.

Recovery snapshot: day case under general or spinal anaesthetic. Pain scores are usually low, and many patients need only simple analgesia. Back to office work within a few days is typical.

PPH — stapled haemorrhoidopexy

PPH stands for “Procedure for Prolapse and Haemorrhoids”. It is designed for patients whose main problem is prolapse right around the anal canal — the classic grade III (and selected grade IV) piles.

What actually happens: a specialised circular stapler is placed into the anal canal. A ring of the prolapsing lining is removed from above the pain-sensitive line, and the stapler simultaneously rejoins the tissue, lifting the whole pile complex back into its normal anatomical position. Because the piles are pulled up rather than cut out, they shrink over the following weeks as their blood supply is interrupted.

Why it’s comfortable: the staple line sits above the dentate line, so — as with HAL/RAR — the pain-sensitive skin is largely undisturbed.

Who it suits: circumferential grade III prolapse, and some grade IV cases where the tissue can still be reduced.

Honest note: PPH gives excellent results in the right patient, but it is a stapling procedure and, rarely, has specific complications (staple line issues, urgency, or narrowing) that we discuss carefully at your consultation. Choosing the right procedure for the right patient is exactly why the examination matters.

Recovery snapshot: day case or overnight stay, general or spinal anaesthetic, most patients back to office work within a week.

At a glance

HAL/RAR — best for bleeding grade II–III piles with some prolapse; day case; low post-op pain; back to desk work in 3–5 days.
Laser (LHP) — best for bleeding grade II and selected grade III piles; day case; very low post-op pain; back to desk work in a few days.
PPH (stapled) — best for circumferential grade III (selected grade IV) prolapse; day case or one night; low post-op pain relative to classic surgery; back to desk work within a week.
Classic haemorrhoidectomy — still the right answer for large, external, skin-tag-heavy or thrombosed piles; more painful early recovery but definitive.

How Dr Marais chooses

The right procedure depends on more than the grade. At your consultation we look at:

How many pile cushions are involved and how much they prolapse.
Whether the main complaint is bleeding, prolapse, discomfort or hygiene.
Whether there is a significant external component or skin tags.
Your priorities — pain tolerance, time available off work, and how important minimising recurrence risk is to you.
Any medications (especially blood thinners) and other health conditions.

Sometimes the honest answer is that a combined approach — for example laser plus a small mucopexy, or PPH with a targeted excision of an external tag — gives the best result. That plan is made together with you before the day of surgery.

On the day and afterwards

All three procedures are done in theatre under general or spinal anaesthetic. You are usually home the same day. In the first two weeks:

Take the prescribed pain medication regularly for the first few days rather than waiting for pain to build up.
Keep stools soft — plenty of water, fibre, and a stool softener if prescribed. Straining is what caused the piles in the first place.
Warm sitz baths after bowel motions help enormously.
Some bright red spotting for a week or two is normal. Heavy bleeding, fever, or difficulty passing urine is not — contact us straight away.

Booking a consult

If piles are affecting your daily life, the sensible next step is an examination — grading them properly is what makes the treatment decision straightforward. You can book a consultation on the contact page, or read more about our approach on the haemorrhoids and piles treatment page.
