Haemorrhoids Flashcards
1) What are haemorrhoids?
2) What are anal cushions?
1) Enlarged and swollen anal vascular cushions
2) Specialised submucosal tissue that contain connections between the arteries and veins, making them very vascular
Name 2 risk factors for developing hemorrhoids
- Obesity
- Pregnancy
- Older age
- Increased intra-abdominal pressure i.e. weightlifting
1) What 2 things are haemorrhoids often associated with?
2) Name 2 ways haemorrhoids may present
1) Constipation and straining
2) Painless, bright red bleeding that is not mixed with stool, sore or itchy anys and feeling a lump around or inside the anus
Name 2 aspects of the medical management of haemorrhoids
- Topical analgesics
- Laxatives
- Topical steroids for short periods only
Name a non-surgical treatment of haemorrhoids
- Rubber band ligation (fitting a tight rubber band around the base of the haemorrhoid to cut off the blood supply)
- Injection sclerotherapy (injection of phenol oil into the haemorrhoid to cause sclerosis and atrophy)
- Infrared coagulation (infrared light is applied to damage the blood supply)
- Bipolar diathermy (electrical current applied directly to the haemorrhoid to destroy it)
Name a surgical treatment of haemorrhoids
- Haemorrhoidal artery ligation involves using a proctoscope to identify the blood vessel that supplies the haemorrhoids and suturing it to cut off the blood supply.
- Haemorrhoidectomy involves excising the haemorrhoid. Removing the anal cushions may result in faecal incontinence.
- Stapled haemorrhoidectomy involves using a special device that excises a ring of hemorrhoidal tissue at the same time as adding a circle of staples in the anal canal. The staples remain in place long-term.
What causes thrombosed haemorrhoids?
Strangulation at the base of the haemorrhoid that can become very painful
