Example text

Elevated resting pressures are associated with the presence of anal fissures. The notion that 20 impaired vascular supply caused by raised internal anal sphincter tone causes anal fissures is supported by the findings of Doppler laser flowmetry [43]. The posterior midline, the most common site of an anal fissure, has been shown to receive the lowest flow rate of the four segments. In addition, there is a direct relationship between resting anal pressure and anodermal blood flow, with decreased resting pressures resulting in increased blood flow.

The anal sphincter is shorter anteriorly in women, which can be misinterpreted as an anterior sphincter defect. Application of pressure to the rectovaginal septum can reveal the presence of a rectocele [26]. The size of the weakness can be estimated as localised or diffuse. The anal canal pressure can be estimated digitally during straining or attempted defaecation. The absence of an increase in anal canal pressure under these circumstances suggests the absence of anismus [27]. 2 Anorectal Physiology Attempted Defaecation and Balloon Expulsion Patients with symptoms of prolapse and elderly patients with a history of constipation who present with passive incontinence should be thoroughly examined for the presence of a full-thickness rectal prolapse.

As the pudendal nerve is mixed and contains the afferent fibres from the anal canal, it follows that the anal canal sensation should be impaired in these patients. Indeed this has been shown, with reduced mucosal electrosensitivity and reduced temperature sensibility. The role of rectal hypersensitivity in faecal urge incontinence and urgency has been investigated. Chan et al. have found a small subset of individuals with urge faecal incontinence who have enhanced rectal perception of rectal distension which worsens stool frequency and urgency [91].
