The surgical removal of internal or external haemorrhoids that are extensive or severe is known as hemorrhoidectomy. It is commonly known as piles surgery. Surgical removal hemorrhoidectomy is the most effective treatment, but it is associated with the greatest rate of complications.
Haemorrhoids may occur as internal or external in nature. Internal haemorrhoids form in the anus or rectum whereas external haemorrhoids form outside the anus. Haemorrhoids are also referred to as piles. The different grades of internal haemorrhoids include:
|Grade I||Haemorrhoids bleed but do not prolapse|
|Grade II||Haemorrhoids prolapse outside the anal canal but resolve on their own|
|Grade III||Haemorrhoids protrude outside the anal canal and are usually reduced manually|
|Grade IV||Haemorrhoid prolapse that cannot be reduced|
Generally, piles are caused due to excessive pressure in the lower rectum. It may be caused by continuous constipation, diarrhoea, pregnancy, lifting heavy weights, obesity and straining while passing stool. Patients with piles complain of painless bleeding. External haemorrhoids are painful.
