After a brief account of the origins of laparoscopy and of its development into an interventional technique thanks to technical improvement, the author gives a dynamic state of the art in laparoscopic surgery, beginning with a description of his original classification method for laparoscopic procedures according to their level of use. Before tackling the highly controversial issue of laparoscopic surgery for cancer, he reviews in detail the various operations successfully performed by laparoscopy for the treatment of nonmalignant abdominal disorders and acute syndromes, all the while checking their results against those obtained with their open counterparts. As the various procedures are described, the interest of the laparoscopic approach becomes clearly visible, based on the excellent view of the operative field that allows diagnostic accuracy, thus avoiding unnecessary operations, and precise dissection with minimal damage. However, the laparoscopic approach is highly dependent on the surgeon’s proficiency, itself depending on experience and therefore on the frequency of occurrence of the disorder, and on the progress in and availability of adequate equipments. The last chapter looks into the future of this ever-expanding approach and defines two great trends in its evolution, one accessible to the individual surgeon, the gradual adaptation of open procedures into laparoscopic ones, the other at the institutional level, in view of the huge financial support involved if high technologies are to be systematically integrated in this new surgery. What will the future be like?
