Haemorrhoid Banding in Hong Kong

A general guide to rubber-band ligation for selected internal haemorrhoids. This information does not confirm that a particular clinician or clinic provides the procedure.

Dr Paul Ng is a Hong Kong gastroenterologist and hepatologist. Consultations in Central and Tsim Sha Tsui are by appointment; confirm the procedure location with the nurses.

PROCEDURE INFORMATION

Introduction

Rubber-band ligation places a small elastic band around the base of an internal haemorrhoid, above the sensitive area at the anal opening. Reduced blood flow allows the banded tissue to wither and detach; a small scar may help hold the lining in place.

When banding may be considered

A clinician may discuss banding for bleeding or prolapsing internal haemorrhoids that remain troublesome despite measures such as fibre, fluids and avoiding straining. It is an office-based option for selected internal haemorrhoids, not a treatment for every anal symptom or for external haemorrhoids.

Rectal bleeding should not automatically be attributed to haemorrhoids. Examination and, depending on age, symptoms and history, further investigation may be needed to check for another cause before treatment is chosen.

What to expect

After assessment, a small instrument is used to place one or more bands around the selected tissue. The band is placed above the sensitive anal canal; the procedure is usually brief. A pressure sensation, urge to pass stool or mild discomfort can occur. The banded tissue commonly separates over several days, sometimes with a small amount of bleeding.

The number of areas treated and whether repeat sessions are appropriate depend on the findings and symptoms. The treating team should explain preparation, medicines that affect bleeding, aftercare and who to contact before the procedure.

Risks and other options

Possible effects include pressure, pain, bleeding when the banded tissue separates, and difficulty passing urine. Rare but serious complications include heavy bleeding or infection. Seek urgent care for heavy bleeding, fever, severe or increasing pain, or difficulty urinating.

Options depend on the diagnosis and severity: bowel-habit changes, other office treatments, or surgery may be discussed. Banding does not guarantee that symptoms will not return. A clinician should review personal risks, including blood-thinning medicines, before deciding.

This is general patient information, not an offer of treatment or a personal recommendation. Seek medical assessment for new or persistent rectal bleeding.
