When hemorrhoids get to very intense stage, they protrude and can never be manually reinserted, the sufferer has to perform an intervention that solves the problem definitively. In particular, the action involves the hemorrhoids of grade III and IV, the most serious ones, and such operations are proposed to decongest the hemorrhoids through mechanical ways, which provide the elastic ligature, of chemical nature such as sclerotherapy, and thermal nature, that use cold or hot as cryotherapy and laser therapy.

It is important to consider that surgery for hemorrhoids is only implemented when all other remedies, both pharmacological and natural and manuals, have not produced satisfactory results in resolving the problem.
