One of the main challenges in transluminal surgery is sterile and safe access. For many interventions, a transanal approach would be ideal but it is considered too risky because of contamination and the danger of secondary leakage. A new safe and sterile transanal access was developed, combining four basic principles: (i) the creation of a decontaminating hydroperitoneum, (ii) the use of an overtube, (iii) defining the entry point with ultrasound and (iv) dedicated closure technique. Applicability and reliability was first proven in extensive animal experiments. Feasibility of the concept in humans was subsequently demonstrated in cadavers.
经腔手术的主要挑战之一是无菌和安全的进入途径。对于许多介入手术，经肛门入路是理想的，但由于污染和二次渗漏的危险，被认为风险太大。开发了一种新的安全和无菌的经肛门进入方法，结合了四个基本原理：（i）创建一个消毒的腹腔积气，（ii）使用护套管，（iii）用超声定义进入点，以及（iv）专用的闭合技术。该方法的适用性和可靠性首先在广泛的动物实验中得到了验证。随后在尸体上证明了该概念在人体中的可行性。
