This running stitch is then tightened to draw up the lax tissue. A small dissolvable stitch (ligature) is then placed around the vessel feeding the haemorrhoid to seal it off.įor the RAR part, the Doppler probe is removed and a running stitch (plication suture) is placed along the length of the prolapsed haemorrhoid. This vessel lies within the lining of the rectum above the haemorrhoidal cushion. This ultrasound probe is then used to find the exact positions of the vessel (artery) supplying blood to the haemorrhoidal cushion containing the haemorrhoid(s). RAR ( rectoanal repair) is the second part, which fixes the prolapsing part of the haemorrhoid by lifting it up and stitching it back into its normal place in the rectum.įor the HALO part, a narrow plastic tube (proctoscope) with an embedded micro-Doppler ultrasound probe is placed in the anus. This stops the bleeding and makes the haemorrhoid smaller. HALO (haemorrhoidal artery ligation operation) is the first part, which cuts off the blood supply to the haemorrhoid. HALO-RAR* is a two-stage open procedure designed to treat internal and external haemorrhoids that are swollen, bleeding and prolapsing, without removing the haemorrhoidal tissue completely by haemorrhoidectomy.
