Comparative ts udy of gasless laparoscopic cholecystce tomy using umbrella-like abdominal wall-lifting device versus pneumopre itoneum in animal experiments
Abstract：Objective To evaluate the application effect of gasless laparoscopic cholecystectomy using um-brella-like abdominal wall-lifting device in animal experiments .Methods Twenty-seven pigs who received laparosop-ic cholecystectomy were randomly divided into two groups .One group was treated with gasless technique using um-brella-like abdominal wall-ifting device (umbrella group,n=15 ).Another group underwent pneumoperitoneum (gas group,n=12).The parameters were compared , including time of establishing operation space , time of gallbladder removal, bleeding volume and the unexpected occurrences during the operation between two groups .Results All the surgeries were completed successfully without conversion to open procedure in two groups .The time of establishing operation space was no difference between two groups ( P>0.05 ) .The greater omentum got stuck on the spokes dur-ing the process of opening the umbrella in two cases of umbrella group , there were no complications of massive hemor-rhage and internal organ injury during the operations .There was no significant difference in unexpected occurrences between two groups ( P=0.487 ) .Conclusion These exeperiment outcomes indicate that the umbrella-like abdominal wall-lifting device is feasible and safe in gasless laparoscopic cholecystectomy in animal experiments .
