What is the difference between open and laparoscopic procedures?

Use of laparoscopic techniques promotes early recovery, and reduced complications like adhesions and hernias. Laparoscopic surgery, sometimes called keyhole surgery, also reduces the amount of pain when compared to open surgery where major, long incisions are required. By allowing the patient to breathe easier and deeper after the procedure, a laparoscopic approach reduces the chance of pneumonia, atelectasis, which is a collapse of air sacs in the lungs, and respiratory failure. In addition to reduced pain, surgery performed this way permits the patient to be up and about sooner. This reduces the chances of complications like deep vein thrombosis (blood clots in the legs) and pulmonary embolisms (blood clots in the lungs). The patient can usually return to normal functions in as little as two weeks compared to four to six weeks after open surgery.
