Anorectal Disease Treatments and Outcomes

Objective : To determine how parturient women tolerate the use of a perineal distensibility assessment technique using the EPI-NO device. Methods : An observational study with a total of 227 full-term parturient women was performed. During the evaluation with EPI-NO, parturient patients were asked about their sensation of discomfort. The degree of discomfort was measured using the Visual Analogue Scale, with a score from zero to 10. The Mann-Whitney test was applied to assess perineal distensibility measured by EPI-NO and the degree of discomfort caused by the test according to parity. The relation between perineal distensibility and discomfort was analyzed by using the Spearman correlation test (r). Results : The test with EPI-NO caused only slight discomfort (mean Visual Analogue Scale of 3.8), and primiparous women reported significantly greater discomfort (mean Visual Analogue Scale of 4.5) than did multiparous (mean Visual Analogue Scale=3.1), with p<0.001 women. A negative correlation was observed, in other words, the greater the perineal distensibility on the EPI-NO, the lower the pain reported by the patients (r=-0.424; p<0.001). Conclusion : The assessment of perineal distensibility with EPI-NO was well tolerated by the parturient women.
