Abstract

An analysis is made of functional studies performed in 96 constipated patients to see how these studies influenced the choice of surgical treatment. All patients underwent anal manometry, and other investigations included colonic transit studies (56), anal sphincter electromyography (42) and defaecatory proctography (34). Additionally nine patients underwent full thickness rectal biopsy. The resting anal canal pressures of the patients studied were lower than controls, and fibre density studies on electromyography were abnormal in half the patients studied suggesting a degree of denervation of the sphincter muscles, which possibly related to chronic straining on the toilet. There was evidenc..
