The first endoluminal operation ever developed was transanal endoscopic microsurgery (TEM), years before laparoscopic cholecystectomy was first performed. Numerous procedures using its single port system (SPS) have since been done and it is now a well-established technique in colorectal surgery around the world. There are some advantages of SPS over multiple port surgery. In 2005 we expanded on the concept of single port surgery with rigid instruments and started to develop instruments for transvaginal single port laparoscopic surgery. We now describe the instruments and system, which include devices that permit a safe access to the abdominal cavity, optimal endoscopic view and instrument steering and a precision that is not reached by current flexible technologies. The devices have been put to the test in an experimental model of transvaginal cholecystectomy. The potential benefits of the technique and the new instruments are discussed.
有史以来开展的首例腔内手术是经肛门内镜显微手术（TEM），比首例腹腔镜胆囊切除术早数年。自那时起，已经使用其单端口系统（SPS）完成了许多手术，现在它在全球结直肠手术中是一项成熟的技术。SPS相对于多端口手术有一些优势。2005年，我们扩展了使用刚性器械进行单端口手术的概念，并开始研发经阴道单端口腹腔镜手术器械。我们现在描述这些器械和系统，其中包括允许安全进入腹腔、获得最佳内镜视野和器械操控以及达到当前柔性技术无法企及的精度的设备。这些设备已在经阴道胆囊切除术的实验模型中进行了测试。本文还讨论了该技术和新器械的潜在益处。
