An undamaged specimen of an imperforate anal membrane, including the rectum, anal canal and its sphincters became available for serial histological sections. The membrane was diaphanous, the internal, and the external sphincters were defective, but the puborectalis muscle though modified by the ...
Eight patients with traumatic transverse lesions of the spinal cord and eight healthy controls were examined with respect to the function of the anal sphincters. Continuous recordings of anal pressure and electromyograms from the striated sphincter muscles were obtained during gradual rectal distension by...
Autonomic Nervous System Function refers to the precise regulation of cardiac activity in normal physiological conditions, which can be disrupted in cardiac diseases leading to disease progression and arrhythmias. AI generated definition based on: Autonomic Neuroscience, 2022 ...

Objectives To evaluate anal sphincter anatomy using three-dimensional ultrasonography (3-DAUS) in incontinent women with vaginal delivery, correlate anatomical findings with symptoms of fecal incontinence and determine the effect of vaginal delivery on anal canal anatomy and function. Methods Female with ...
These data support the hypothesis that sensory function of both the rectum and the anal canal is an important and independent factor in the preservation of continence . 展开 关键词: Fecal incontinence Anorectal motor function Rectal sensitivity Anodermal sensitivity ...
For patients with fecal incontinence that does not resolve on antidiarrheal treatment, functional and structural evaluation with anorectal manometry and endoanal ultrasound or magnetic resonance (MR) of the anal canal may help to guide management. Sacral nerve stimulation is a rapidly evolving alternative...
The distensibility and threshold volume of those with a pouch were significantly greater than in those without a pouch 6 months or more after stoma closure. Anal resting pressure, squeeze pressure, anal canal length and a positive inhibitory reflex were similar in both groups. Anal resting ...
Sphincter muscles are located at different transitional points through the digestive tract. In the anal canal, there are two sphincter muscles. Function of a Sphincter Thesphincteris used to describe contracting circular muscles found throughout the body.Sphincter musclesperform valve-like functions to ...
Preservation of continence after ileoanal anastomosis by the coordination of ileal pouch and anal canal motor activity Nocturnal incontinence may occur after ileoanal anastomosis and may be related to loss of an effective anal canal pressure barrier during sleep; how pressu... A, Ferrara,JH Pembe...
