A Hypothesis of Anal Continence

Influence of perineal prostatectomy on anal continence

OBJECTIVE Perineal prostatectomy has been proposed as a less invasive and safe procedure, but the risk of anal incontinence has been studied. This study aimed to evaluate the effects of perineal access on anal continence mechanisms after perineal prostatectomy. METHODS From August 2008 to May 2009, twenty three patients underwent perineal prostatectomy. These patients were evaluated before su...

Force in the anal canal and anal continence.

Maintenance of anal continence: a review of pelvic floor physiology.

The relation of sensation in the anal canal to the functional anal sphincter: a possible factor in anal continence.

In normal subjects the length of the functional anal sphincter has been compared with the extent of sensation to light touch in the anal canal. At rest, the sphincteric zone was the longer. On distension of the rectum, a decrease in pressure in the anal canal so shortened the functional sphincter that intrarectal pressure extended down to contact the sensory zone. This mechanism may allow the s...

Computerised biofeedback achieving continence in high anal atresia.

Computerised biofeedback has been used to attempt to improve continence in three boys with high anal atresia. The results obtained so far have been extremely encouraging. Over a period of six months progressive improvement has taken place and been maintained in each child.
