Rubber band ligation for haemorrhoids: what happens and what to expect

Banding is aimed at internal haemorrhoids that bleed or drop down but remain manageable, rather than large external lumps. For many people piles settle with changes to diet, fluids and toilet habits, and treatment is only considered when symptoms keep returning despite that groundwork. The NHS lists banding alongside sclerotherapy, electrotherapy and infrared coagulation as options carried out in a hospital clinic without a full anaesthetic.

If the piles are large, prolapse permanently or have not responded to clinic treatments, surgeons may talk instead about haemorrhoidectomy, stapled haemorrhoidopexy or haemorrhoidal artery ligation, all of which the NHS describes as surgical options. Bleeding that is new, dark or mixed with a change in bowel habit is a reason to be examined by a doctor first, because piles are not the only cause of blood from the back passage.

• Sclerotherapy injects a liquid to shrink the pile, according to the NHS.

• Infrared coagulation and electrotherapy use light or current to shrink the tissue.

• Surgery is generally kept for piles that clinic treatments cannot control.

Preparation is usually light because no general anaesthetic is involved. You will be asked about medicines that thin the blood, since these influence the bleeding that can follow once the tissue separates. Tell the clinic about anticoagulants or antiplatelet tablets rather than stopping anything on your own.

Wear loose clothing and plan a quiet rest of the day. A short note of recent bowel habit, how often you bleed and whether the piles come down on straining helps the clinician decide how many piles to treat at a visit.

A hospital leaflet describes the pile being drawn into an applicator tube and a small rubber band being applied over its base, which cuts off the blood supply. The NHS says the area may be numbed. How the procedure feels differs from person to person, so ask the clinician what to expect and tell them if anything hurts while it is happening.

The whole visit is short and you walk out afterwards. Whether one or several piles are banded in one sitting depends on the clinician and on how comfortable you are; further sessions are sometimes planned, and your clinic will tell you its approach.

The pages retrieved for this guide did not give complication percentages, so none are quoted. Aching or a feeling of fullness is common for a few days, and a trust leaflet puts discomfort at between one and seven days. Small amounts of bleeding, particularly when the band separates, are expected.

More important are the less common events: bleeding that is heavy or comes back later, pain that painkillers do not touch, difficulty passing urine and infection near the treated area. One leaflet describes delayed bleeding appearing around ten days after treatment in some people, so a clean first week does not close the matter completely. Ask the clinician what the risk is for you if you take blood thinners.

Simple painkillers such as paracetamol are the usual advice, and two trust leaflets warn against codeine-containing products because they constipate. A warm bath eases discomfort. Soft stools are the aim, so fibre such as wholemeal bread and cereals, vegetables and plenty of fluid are encouraged.

A Bedfordshire leaflet suggests putting off a bowel movement for six to twelve hours if you can, avoiding strenuous exercise on the day, not using applicators for anal creams for 48 hours, and avoiding heavy lifting for two to three weeks. A North Tees leaflet is more relaxed about work and normal activities, saying most people can return to them when they feel able. Follow the advice from your own clinic where it differs. You may notice the band in the toilet; this needs no action.

Go to an emergency department for heavy bleeding, severe pain, or pain with nausea and vomiting, a high fever, dizziness or being unable to pass urine. Call 999 if you feel faint or collapse. For worsening pain, a discharge, swelling or smaller bleeds that worry you, contact your GP, the clinic that treated you, or NHS 111 when those are closed.

• How many piles will be banded today, and could more sessions be needed?

• I take a blood thinner: should I do anything differently?

• What counts as too much bleeding, and whom do I ring out of hours?

• If banding fails, would you suggest another clinic treatment or surgery?

• What can I do to stop the piles returning?

The treatment itself is the same in both settings. The differences are about access: NHS clinics may sit behind a GP referral and a wait, while private clinics usually offer a faster appointment and a choice of clinician. Ask in either setting whether repeat sessions are included, who sees you if a problem arises after hours, and what follow-up is arranged.
