Piles surgery is also known as hemorrhoid surgery. Hemorrhoids are the swollen vessels inside or around the anus and rectum and this surgery is aimed at removing these swollen blood vessels that cause severe bleeding, or pain. However, it is important to understand that surgery is recommended only when other changes such as a change in diet, etc. are ineffective or to remove multiple hemorrhoids.
Piles can be of two types depending on their location:
External: They form under the skin of the anus. Symptoms of this condition are itching, pain around the anus, or formation of tender lumps.
Internal: They form within the lining of the anus and lower rectum. Symptoms of this condition include bleeding during bowel movements, or hemorrhoid falling out of the anus.
