[Use of abdominal wall retractor Laparo Tenser in gasless laparoscopic cholecystectomy].

High pressure CO2-peritoneum for laparoscopic surgery is not indicated in patients with impairment of cardiorespiratory and renal function and in high risk patients and in obesity. On the other site the uncontrolled abdominal insufflation and the blind insertion of the first trocar in patients with extended intraperitoneal adhesions, often cause bleeding and the intestinal loops dislocation, and can determine visceral lesions. In these patients gasless technique with an abdominal laparolifter can be employed. We report an experience of 36 patients undergoing laparoscopic cholecystectomy by a subcutaneous planar retractor. It was observed a good operative exposure in 83.3%; the surgery was safely performed in 88.8%. Two suprafascial hematoma related to the insertion of the needles of the Laparo Tenser occurred. A regular post-operative discharge was observed in 84.4%. These good results supports the extension of the laparoscopic approach for the cholecystectomy to complicated or to high risk patients.
