In order to avoid extension of the parietal wound when the stone load is too large to be simply extracted in laparoscopic cholecystectomy, we developed a new extraction bag. The new extraction bag has a characteristic shape to arrange the stones or fragments in a linear order. To evaluate the efficacy of the new bag we conducted in vitro stone extraction experiments and compared the new bag technique with conventional stone removal techniques. Mean experiment time to extract 60 small stones in a conventional technique group was 710 seconds, whereas it was 316 seconds with the new bag technique (p < 0.001). With this technique larger stones are also extracted without extending the parietal incision once they are fragmented in the bag. The results of our experiments suggest the new extraction bag as a simple and safe technique in minimally invasive stone extraction in laparoscopic cholecystectomy.
在腹腔镜胆囊切除术中，当结石负荷过大而无法简单取出时，为避免腹壁伤口扩大，我们研发了一种新型取出袋。这种新型取出袋具有独特形状，能将结石或碎片排列成线性顺序。为评估新型袋子的效果，我们进行了体外结石取出实验，并将新型袋子技术与传统结石取出技术进行了比较。传统技术组取出60颗小结石的平均实验时间为710秒，而新型袋子技术为316秒（p < 0.001）。采用该技术，较大结石在袋内破碎后也能在不扩大腹壁切口的情况下取出。我们的实验结果表明，新型取出袋是腹腔镜胆囊切除术中微创结石取出的一种简单且安全的技术。
