In a controlled clinical trial-manual vs. stapler anastomosis in rectal surgery-it was found that both suture techniques per se made no difference in the function of anal continence. The anal pressures at rest and sphincter contraction remained unchanged. A linear reduction of functional reservoir of the "neorectum" could be shown, which depended on the level and healing of the anastomosis. An anastomosis level at 6 cm from anocutaneous line is important for functional reasons. Anastomoses above this level do not cause any consequences for anal continence. Anastomoses below this level result in a reduced functional reservoir for at least 6 months. Within this period a decrease in anal continence is possible, especially in cases of disturbed healing of the anastomosis.
在一项对照临床试验中——直肠手术中手工吻合与吻合器吻合的对比——发现两种缝合技术本身对肛门节制功能并无差异。静息时和括约肌收缩时的肛门压力保持不变。可以显示出“新直肠”功能贮器呈线性减少，这取决于吻合口的水平和愈合情况。从肛门皮肤线起6厘米处的吻合口水平出于功能原因很重要。高于此水平的吻合口对肛门节制不会造成任何影响。低于此水平的吻合口会导致功能贮器至少在6个月内减少。在此期间，肛门节制可能会下降，尤其是在吻合口愈合不良的情况下。
