The HALO procedure is an operation performed under general anaesthetic to reduce the blood flow to your haemorrhoids. A small ultrasound probe is inserted into your anus to identify the blood vessels supplying the haemorrhoid, which are then tied off with stitches. This results in the haemorrhoid shrinking. Further stitches can also be used to reduce any haemorrhoidal tissue that hangs down from the anus. The procedure causes less pain than the traditional haemorrhoidectomy operation but has equally as good results. The post operative recovery time is also quicker compared to other surgical procedures. It is not suitable for all patients so a detailed discussion with your colorectal specialist is advised.
