Does surgery for piles result in loss of control of stools ?

Whenever a patient is subjected to an operative procedure for any anorectal conditions the first step is to stretch the anal sphincter gently till it admits 2 or 3 fingers. This is known as anal dilatation. This procedure is learnt by surgeons in their training period under supervision of seniors. During a surgical residency a surgeon will perform and teach to juniors this procedure hundreds of times and hence it is very unlikely that incontinence will occur at the hands of a trained surgeon.
Sporadically, patients develop incontinence after a procedure if inadvertent over stretching is done.This problem is so peculiarly unpleasant that it is a sensational news in the patients family and acquaintances and spreads reasonably fast and wide leading to adverse publicity that "piles operation leads to incontinence".
