Objective: Anorectal manometry is still a pillar in the study of anorectal and defecation disorder, used in research and clinical setting, giving indication for treatment and suggesting the cause of the cited disorder. In this retrospective study we analysed the demographics and the anorectal manometric profile findings of the patients with faecal incontinence submitted to anorectal manometry in a recently opened anorectal physiology service of a private hospital in São Paulo.
Method: This is a retrospective study. We analysed the patients who underwent to an anorectal manometry from October 2015 to June 2017. We analysed 29 patients, 8 males and 21 females (27,58% and 72,41% respectively), aged from 20 to 85 years old (mean age 57,97 y.o.). Wexner Incontinence Score was calculated for all patients (min 2 - max 20 mean 9,14). We measured the Mean Resting Pressure (min 6,3mmHg max 123,6mmHg mean 47,9mmHg), the Maximal Squeezing Pressure or Voluntary Contraction Pressure (56-222,5mmHg mean value 127,55). We found that 11 patients had anismus (37,9%) and 1 patient (3,45%) had no RAIR (Rectoanal Inibitory Reflex) in the exam. 6 patients has dyssynergic anorectal function (20,68%). Anal sensibility (min 10-max 135 mean 38mL), evacuatory sensibility (min 25-max 175 mean 65,34mL) and maximum rectal capacity (min 45-max 230 mean 118,10mL) were also evaluated.
Conclusion: Some peculiar data can be extracted from this population, especially the association of faecal incontinence with dyssynergic pelvic function and anismus is quite significant in a broader view of faecal incontinence as a part of a global dysfunction of pelvic function, and deserves more research studies.
