Six patients underwent objective measurement of anorectal sensory function following abdominoperineal excision of the rectum and total anorectal reconstruction. No patient perceived neorectal distension as a desire to defaecate or as a feeling of flatus. Anal mucosal sensation was preserved in two patients in whom some anal mucosa was retained. These sensory deficiencies may result in faecal retention and incontinence in patients undergoing reconstructive surgery. The loss of rectal sensation suggests that the prime sensors of rectal filling may lie within the rectum itself.
六名患者在接受直肠腹会阴切除及全肛管直肠重建术后接受了肛管直肠感觉功能的客观测量。没有患者将新直肠扩张感知为排便欲望或肠胀气感觉。两名保留了部分肛管黏膜的患者保留了肛管黏膜感觉。这些感觉缺陷可能导致接受重建手术的患者出现粪便潴留和失禁。直肠感觉的丧失表明直肠充盈的主要感受器可能位于直肠本身。
