THE ROLE OF MANOMETRY, ELECTROMYOGRAPHY AND RADIOLOGY IN THE ASSESSMENT OF FECAL INCONTINENCE

Abstract

The results of laboratory investigations in 156 patients presenting with faecal incontinence are reviewed to see if and how these investigations supplement a careful clinical evaluation, and in particular to see if they help in the practical management of the problem. All patients underwent anal manometry, and in addition 52 underwent anal sphincter electromyography and 27 defaecatory proctography. Anal manometry quantified sphincteric weakness, and proved superior to digital assessment in this regard. Resting and squeeze pressures were less in those with complete than those with partial incontinence but the differences were not statistically significant. The measurements of rectal sensation..
