What is piles ligation?
Piles ligation, also known as rubber band ligation, is a non-surgical procedure to treat internal haemorrhoids that protrude during bowel movement. A small rubber band is used to tie off the base of the haemorrhoid. This cuts off the blood supply to the haemorrhoid, causing the haemorrhoid to die and fall off in a few days and the wound to heal within one to two weeks. A scar will be formed in the place of the haemorrhoid. It holds the surrounding veins to prevent them from bulging into your anal canal.
How is piles ligation carried out?
Your doctor inserts an anoscope into your anus to look inside your anus and rectum. Another special instrument is used to grasp the haemorrhoid and a device places a rubber band around the base of the haemorrhoid.
Who should undergo piles ligation?
If your piles are not prolapsed, piles ligation would be suitable to treat your condition. Piles ligation is commonly performed for recurrent haemorrhoids that cause significant pain, such as second degree haemorrhoids. It is a simple procedure that can be done in the doctor’s office or as an outpatient case.
Piles ligation is generally highly effective for second degree haemorrhoids, with 8 in 10 people recovering fully. One to two haemorrhoids can be removed in a single procedure, and another procedure can be carried out after 4 to 6 weeks. It prevents the piles from returning and repeat treatment is not needed. However, this procedure is not suitable for third or fourth degree haemorrhoids where your piles has prolapsed and require surgery. Haemorrhoidectomy may be recommended in these cases.
