title: [Application of gasless laparoscopic device in laparoscopic surgery].
abstract: The aim of this study was to evaluate the gasless laparoscopic device (GLD) in laparoscopic surgery. GLD, independently designed and manufactured by ourselves in 1993, incorporates a manipulator and laparoscopic abdominal retractor. From August to October 1993, we conducted an experimental study on gasless laparoscopic cholecysto-duodenostomy in 5 dogs. Four of them were completely successful and one was converted to open surgery due to gallbladder rupture. The result showed that GLD could maintain good exposure in laparoscopic surgery, laparoscopic suturing and knotting could become easier and operative cost could be reduced with conventional instruments. We also developed an intracorporeal "Chinese Knotting" and a self-designed push tube for extracorporeal knot tying. During April and August 1994, we successfully applied our modified GLD in gasless laparoscopic cholecystectomy, inguinal herniorrhaphy laparoscopic-assisted sigmoidectomy, abdomino-perineal resection of rectal carcinoma.
