We found the infection rate to be significantly lower performing metachronous procedures although surgery lasted significantly longer than synchronous extirpation. From our results and other data from literature we conclude that occlusion of the natural anus in case of treatment with synchronous procedure leads to high intraluminal pressures during mobilisation of the rectum from sacral cavity. This enables germs to pass through the intact intestinal wall and results in contamination of the wound cavity.
我们发现，尽管异时手术的持续时间明显长于同期切除手术，但异时手术的感染率显著更低。根据我们的研究结果以及文献中的其他数据，我们得出结论，在进行同期手术治疗时，自然肛门的闭塞会导致在从骶骨腔游离直肠的过程中管腔内压力升高。这使得细菌能够穿过完整的肠壁，从而导致伤口腔污染。
