Hemorrhoid surgery - series
Normal anatomy
The rectum is the final portion of the large intestine. It empties stool from the body through the anus. Hemorrhoids are "cushions" of tissue filled with blood vessels at the junction of the rectum and the anus.
Indications
These vascular cushions can become swollen and inflamed, usually due to increased intra-abdominal pressure, such as during straining when constipated or during pregnancy. Such swelling can cause pain, bleeding, and itching. Hemorrhoid removal may be recommended when non-surgical treatment (fiber rich diet, laxatives, stool softener, suppositories, medications, warm baths) has not provided adequate relief from:
- persistent itching
- anal bleeding
- pain
- blood clots (thrombosis of the hemorrhoids)
Procedure
The hemorrhoid is ligated at its base, to prevent bleeding from the blood vessels within the hemorrhoid, then it is removed surgically. Alternatively, some surgeons will simply apply a rubber band around the base of the hemorrhoid (banding); deprived of its blood supply, the hemorrhoid will then simply fall off and be passed in the stool. Finally, some surgeons will inject the base of the hemorrhoid with a sclerosing agent (sclerotherapy), which also destroys the vessels in the hemorrhoid, causing it to fall off and be passed in the stool.
Aftercare
The outcome is very good in more than 90% of the cases. The patient may experience considerable pain after surgery as the anus tightens and relaxes. Medications to relieve pain may be used. To avoid straining, stool softeners will be used. Avoid any straining during bowel movement or urination. Soaking in a warm bath can bring additional comfort. Expect complete recovery in about 2 weeks.
