OBJECTIVE: to evaluate the average resulting area from the Pressure x Time curves resulting from the manometric anorectal exam and compare it with the support capacity of voluntary squeeze.
MATERIALS AND METHODS: the data set was represented by data from 11 exams from continent patients and eight exams from patients with grade III fecal incontinence. The manometric curves were delineated, and the areas and support capacity of voluntary squeeze calculated, by means of the R computer language and the algorithm developed.
RESULTS: the resulting averages for support capacity of voluntary squeeze in continent patients and patients with grade III fecal incontinence were 33.07 seconds and 30.76 seconds (p>0.05) and the averages for area were 2362.04 mmHg x second and 947.92 mmHg x second (p<0.05), respectively.
CONCLUSION: the average resulting area is able to differentiate continent patients from incontinent and is shown to be a possible parameter in the analysis of biomechanical behavior related to the mechanisms of anorectal continence.
