Introduction
Welcome to the world of modern surgery ruled by Laparoscopy, Laser and many other minimal invasive techniques which you are going to marvel as you read on. Gone are the days when surgeons used to make big cuts to remove gall bladder stones, darn a defect in a hernia, or take out colon or rectum cancers. Now they do the same job using a few holes to send their instruments inside the abdomen which is relatively painless and reduces the hospital stay! Or take the case of one of the commonest ailments like Piles and Fistula. Earlier, surgeons left a severely painful wound around the anus after surgery that needed months of dressing, restricted activity and inability to resume work for a long period. With Laser, there is no wound at all because nothing is cut. Using laser energy the surgeon ablate the piles, close a nagging fistula.
