DGHAL
DGHAL or HALO is performed under general anaesthetic. This operation is designed to eradicate piles without the need for cutting. The operation uses a miniature ultrasound device to locate the blood vessels supplying the haemorrhoids. The aim of the operation is to cut off the blood supply to the haemorrhoids. This is achieved by placing a stitch around each blood vessel. Over the following few weeks to months, the piles shrink away and the symptoms resolve. Some pain is to be expected for several days after the operation and this is usual.
