Anal sphincter dilatation with forefinger and middle fingers of both hands for a two-minute period under strong pressure results in a measurable tonus-decrease of the sphincter ani over a period of 2-3 weeks. This tonus-decrease is of therapeutic advantage in numerous diseases, particularly in those of the anal area. At the same time, the stretching may well be used to protect anastomoses in the colon or to dilate the operative access in transanal operations. Complications arising from the stretching described are insignificant.
双手食指和中指在强压力下对肛门括约肌进行两分钟扩张，会导致肛门括约肌张力在2至3周内出现可测量的下降。这种张力下降在许多疾病中具有治疗优势，尤其是在肛门区域的疾病中。同时，这种拉伸很可能用于保护结肠吻合口或在经肛门手术中扩大手术入路。所述拉伸引起的并发症并不严重。
