伞式免气腹技术与气腹技术行腹腔镜胆囊切除术的动物实验对比研究

目的：探讨伞式腹壁悬吊装置在动物实验中行免气腹腹腔镜胆囊切除术的应用效果。方法将27头实验猪随机分为两组，分别应用伞式免气腹技术（伞式组，n＝15）和气腹技术（气腹组，n＝12）进行腹腔镜胆囊切除术，比较两组建立手术空间时间、胆囊切除时间、术中出血量及术中意外情况。结果两组手术均顺利完成，伞式组建立手术空间时间、胆囊切除时间、术中出血量与气腹组比较差异无统计学意义（P均＞0.05）。伞式组有2例出现大网膜钩挂于伞叶上。两组均无中转开腹手术，无术中大出血、器官损伤等严重并发症。两组在术中意外情况的比较差异无统计学意义（ P＝0.487）。结论应用伞式腹壁悬吊装置在动物实验中行腹腔镜胆囊切除术是安全可行的。

Comparative study of gasless laparoscopic cholecystectomy using umbrella-like abdominal wall-lifting device versus pneumoperitoneum in animal experiments

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 .
