Abstract

With the advent of laparoscopic operations, a new age in the surgery was initiated. It was the change of the paradigm "great surgeons - great incisions", for the new concept of less invasive surgery and its consequences: lesser surgical trauma, lesser postoperative pain, better aesthetic result and less complication in the incision. However, the scientific and technological advances had not ceased, and the search for less invasive surgical accesses has been a constant. In this context appeared a new way to do laparoscopic surgery, known as SILS (single incision laparoscopic surgery), where only one troccar is introduced in the abdominal wall. With the published initial results, this surgical technique presents as promising in relation to little postoperative pain and better aesthetic effect. However, if confirmed with an adequate number of patients, it's expected that this technique can generate a less systemic inflammatory response in comparison with the conventional laparoscopy, what it would have an evident benefit in the patients of higher surgical risk that must be submitted to the possible minor stress. The great problem of this new technique is the high cost. We hope, with this work, to demonstrate the real value of this new way of surgical access in comparison with the conventional laparoscopy, in terms of lesser systemic inflammatory response, using a number of patients ideal for statistical analysis.
