The purpose of the present work is to evaluate the function of the anal sphincter following anterior resections of the rectum. Our data have shown that the anorectal reflex did not depend on the presence of the rectal mucosa. The external anal sphincter contraction involves a reflex which is initiated by stretch receptors in the levator ani muscle. The internal anal sphincter relaxation is likely a local reflex involving nerve pathways not yet completely defined.
本研究的目的是评估直肠前切除术后肛门括约肌的功能。我们的数据表明，肛门直肠反射并不依赖于直肠黏膜的存在。肛门外括约肌收缩涉及一种由肛提肌中的牵张感受器引发的反射。肛门内括约肌松弛可能是一种涉及尚未完全明确的神经通路的局部反射。
