    Abstract:
    The pneumoperitoneum as a precondition of laparoscopic procedures represents a restriction of the surgeons freedom of movement and causes rare but typical complications. In July 1993 we started doing laparoscopic cholecystectomy without using a pneumoperitoneum. Under direct vision and digital control the retractor blades are introduced into the abdominal cavity via minilaparotomy. The retractor is attached to an electrically powered mechanical arm and raised. The scope is introduced through the same access and the laparoscopic cholecystectomy can be performed using the established technique without instilling a pneumoperitoneum. Both conventional and laparoscopic surgical instruments were introduced through valveless trocars and unlimited suction without loss of gas and exposure is possible. Metabolic and hemodynamic alterations associated with the intraperitoneal insufflation of carbon dioxide are omitted. So far we did gasless laparoscopic cholecystectomy in 22 patients. We didn't see any related complications. Four times we had to change the surgical procedure. In comparison to the traditional laparoscopic cholecystectomy with a CO2-pneumoperitoneum the results of the first gasless procedures demonstrate possible advantages.
