[Gasless versus conventional laparoscopic cholecystectomy. A randomized trial with regard to technical problems, postoperative course and convalescence].

Introduction: The positive CO2 pneumoperitoneum needed to create the working space for laparoscopic surgery may induce pathophysiological changes. Concern about these changes has led to the introduction of a gasless technique. The aim of the present study was to compare the gasless CLC and GLC with regard to exposure, technical problems, operation time, postoperative pain, clinical course, and convalescence.
