Symptomatic
Sclerosation therapy with 5% phenol in almond oil
Rubber band ligation
Open haemorrhoidectomy
Stapled haemorrhoidectomy
HALO/THD procedure
What is the HALO/TDH procedure?
Hemorrhoidal artery ligation
Mini doppler ultrasound device locates branches of arteries supplying the haemorrhoids. Blood vessels tied off and haemorrhoids shrink over days and weeks.
(Pain free as stitch is placed in lower rectum where virtually no sensory nerves)
