Alongside the technique based on the creation of an abdominal cavity for surgery following the introduction of gas (usually CO2) into the peritoneal cavity, a new method has been developed. This involves the use of an atraumatic mechanical lifting device connected to the same abdominal wall (gasless laparoscopy). The authors report a technique that uses an inflatable cushion inserted into the abdomen through a periumbilical incision. The cushion is connected to an external motorized hydraulic jack fixed to the operating table, fitted with an electric motor and friction gear. Between May 1991 and June 1998, 580 patients underwent laparoscopic cholecystectomy. Since December 1995 a total of 130 patients have undergone surgery using gasless laparoscopy. Shoulder pain and pain in the upper abdominal quadrant were no longer reported; pain was present in 70% of the patients operated using the CO2 technique. There was also a marked reduction in the anesthesiological risks, above all in elderly patients with cardiopulmonary insufficiency. Surgical manoeuvres are made easier owing to the possibility of using traditional surgical instruments. Washing and continuous aspiration allow a good control of intraoperative hemostasis, and reduce the phenomenon of lens misting without the risk of losing pneumoperitoneum. Less visibility of the surgical field was reported, particularly in obese patients, above all because of the reduced diaphragmatic distension and the lack of displacement of the intestinal loops. In the authors' opinion the gasless technique is suitable above all in patients affected by cardiopulmonary disorders in whom hypercapnia might represent a significant operating risk.
