title: [Videolaparoscopic appendectomy with linear stapler].
abstract: It is presented the experience of 126 cases of acute appendicitis treated by a videolaparoscopic appendectomy using a 12 mm endostapler with 4 lines of staples and a linear cutting device in the middle. It has been used two trocars (5 mm) at the left side and one other (12 mm) trocar at the umbilicus. In the first cases other dispositions were used but this one seemed to be better. Through the left trocars, a dissection is promoted, isolating the appendix, its base and its mesentery, in which a small hole is made, close to the base. Through this hole, it is passed one of the sides of the 12 mm stapler. The device promotes the bilateral stapling and cuts the appendix at its base. The stapler is reloaded with vascular staples and then the mesentery is stapled and cut by the same way. It is a very fast method. Besides, the laparoscopic option gives the opportunity to equally treat appendicitis at unusual positions, to examine other pelvic organs (eventually treating diseases) and to aspirate secretions under direct view, anywhere in the cavity. The specimen is taken out of the cavity inside a plastic bag and we had no case of infection at the trocar sites. Only in 3 cases there were conversion to open surgery, due to difficult dissection and identification of structures, in all of them with very advanced disease and necrosis. It is concluded that this method is fast, safe, easy (although more expensive) and can be utilized routinely, at least in the first approach of the treatment of acute appendicitis.
