Management of haemorrhoids conservative and non-surgical
Conservative -
- Topical treatments e.g. anusol (contains astringents to shrink the haemorrhoids, germoloids cream (contains lidocaine)
- Prevention of constipation - good fluids/ fibre intake, laxatives PRN
- Avoiding straining
Non-surgical:
- Rubber band ligation
- Injection sclerotherapy - injection of phenol oil into the haemorrhoid to cause sclerosis and atrophy)
- Infra-red coagulation (infra-red light is applied to damage the blood supply)
- Bipolar diathermy (electrical current applied directly to the haemorrhoid to destroy it)
Surgical management of haemorrhoids
Haemorrhoidal artery ligation
Haemorrhoidectomy (or stapled haemorrhoidectomy)
A complication of haemorrhoids can be
Thrombosed haemorrhoids
These are caused by strangulation of the haemorrhoid causing thrombus formation
Present with severe pain - PR often not possible as a result
Resolve with time but can take several weeks
