There are certain treatments that you’ll need to go into hospital for as an outpatient. You won’t usually have to stay overnight. These include the following :-
Banding. This treatment of piles involves placing a small elastic band around the pile, which cuts off the blood supply. This causes it to die and fall off after a few days. The area left behind will heal up naturally.
Sclerotherapy. In this treatment of piles oily phenols are injected into the base of the pile masses (lumps) .This shrinks the piles & clots the blood inside piles.
Infra-red coagulation or laser treatment of piles. This treatment of piles uses infra-red light to seal the veins above the pile, which causes it to shrink.
Bipolar diathermy and direct current electrotherapy treatment of piles - This treatment of piles uses an electrical current to destroy the pile.
Ksahrasutra (Thread Therapy)- Special Ayurvedic medicine for piles are coated on threads which are tied on hemorrhoids to shrink it.
Doppler-guided haemorrhoidal artery ligation. This treatment of piles uses an ultrasound probe to find an artery in your anal canal that can be stitched up to limit the blood supply to your piles.
