Hemorrhoids or piles are swellings containing enlarged blood vessels that are found inside or around the rectum and anus. Hemorrhoids result from increased pressure on the anus.
Risk factors for developing hemorrhoids
The exact cause of hemorrhoids is unclear, but they’re associated with increased pressure in the blood vessels in and around your anus. This pressure can cause the blood vessels in the rectum and anus to become swollen and inflamed.
Factors predisposing to the development of hemorrhoids include:
The pressure causes the normal anal veins and tissue to swell. This tissue can bleed, often during bowel movements.
You may notice the following symptoms:
The severity of symptoms vary in patients and depends upon the grading of the piles and the type of piles:
If untreated, hemorrhoids may cause complications such as anemia with resultant generalized weakness from the chronic blood loss during defecation. There is a risk of developing strangulated haemorrhoids where the blood supply of a prolapsed pile gets occluded by the constriction of the anal sphincter.
What are the treatment options?
Lifestyle changes to reduce the strain on the blood vessels in and around your anus is recommended to reduce the risk of hemorrhoids developing or recurring:
Banding is a non-surgical procedure where a very tight elastic band is put around the base of the haemorrhoid to cut off its blood supply. The hemorrhoid should fall off after about a week.
Sclerotherapy: A chemical is injected into the haemorrhoid to shrink it
Coagulation techniques: Laser or heat energy is used to coagulate blood in the internal hemorrhoids and harden them.
Surgery may be recommended if other treatments for hemorrhoids don’t work. Surgery carried out under general regional anaesthesia is sometimes used to remove or shrink large or external hemorrhoids.
Hemorrhoidectomy: Hemorrhoidectomy is the surgery to remove hemorrhoids. Conventional hemorrhoidectomy involves gently opening the anus so the hemorrhoids can be cut out. Hemorrhoidal artery ligation: Hemorrhoidal artery ligation is an operation to reduce the blood flow to your hemorrhoids. It involves inserting a small ultrasound probe into your anus that locates the vessels supplying blood to the hemorrhoid. Each blood vessel is stitched closed to block the blood supply to the hemorrhoid, which causes the hemorrhoid to shrink over the following days and weeks. The stitches can also be used to reduce prolapsing hemorrhoids (hemorrhoids that hang down from the anus).
Stapling, also known as stapled hemorrhoidopexy, is an alternative to a conventional hemorrhoidectomy. It’s sometimes used to treat prolapsed hemorrhoids.
Stapled hemorrhoidectomy is a misnomer since the surgery does not remove the hemorrhoids but rather, removes the abnormally lax and expanded hemorrhoidal supporting tissue that causes the hemorrhoids to prolapse downward.
In stapled hemorrhoidectomy, the surgery is done through the anal canal. A circular, hollow tube is inserted into the anal canal. The procedure is done through this tube.
During stapled hemorrhoidectomy, the arterial blood vessels that travel within the expanded hemorrhoidal tissue and feed the hemorrhoidal vessels are cut. This reduces the blood flow to the hemorrhoidal vessels and reduces the size of the hemorrhoids.
The staples are needed only until the tissue heals. They then fall off and pass in the stool unnoticed after several weeks. Stapled hemorrhoidectomy is designed primarily to treat internal hemorrhoids, but if external hemorrhoids are present, they may be reduced as well.
Stapling has a shorter recovery time than a traditional hemorrhoidectomy, and you can probably return to work about a week afterwards. It also tends to be a less painful procedure.
What is the post-surgery care that should be taken?
Arthroscopy is a procedure in which a surgeon inspects a joint through a tiny camera. The surgery performed is a nominal insidious surgery.
A knee replacement surgery is performed in order to reduce pain by removing the diseased or damaged part of the knee bone and is replaced.
Hip replacement is also known as Total Hip Arthroplasty and is performed to remove the worn out joint of the hip with an artificial joint or prosthesis.
