There are many treatment options when dealing with the hemorrhoids such as hemorrhoidectomy, hemorrhoid stapling and hemorrhoid banding. Each has an advantage over the other approaches. The main advantages of the hemorrhoid banding are that it is a fairly easy approach that can be done in the outpatient setting and is associated with very few recurrences compared to other modalities of treatment. In addition to this, it is very costeffective. The disadvantage of this approach is that the doctor can only put as many bands in one session; therefore the patient has to make frequent visits to the hospital especially in the case of multiple internal hemorrhoids.
The underlying principle for this form of treatment is the strangulation of the blood supply of the hemorrhoids as they are highly vascularized structures, therefore, they cut off because of the selective ischemia caused by these bands.
