Conventional videodefecography: Pathologic findings according to gender and age

Abstract

Objectives: To review the most common disorders depicted with conventional videodefecography, and to compare the defecographic abnormalities between symptomatic patients according to their gender and age. Methods: Conventional videodefecography studies of 300 patients (24 men, 266 women; mean age – 57.7) performed in a 32-month period were reviewed for the following parameters: anorectal angle, movement of the pelvic floor, intussusceptions, incontinence and rectocele. The results were analyzed using the chi-square test. Results: Normal findings were observed in 16.7% men and 7.5% women. In women, the most frequent pathological findings were rectocele (62%), descending perineum syndrome (42.8%), intussusceptions (33.8%), incontinence (10.5%), dyskinetic puborectalis syndrome (9.4%) and rectal prolapse (4.5%); in men the most frequent pathology was the dyskinetic puborectalis syndrome (37.5%). This syndrome is more likely in men than in women (p = 0.01; OR 5.78); descending perineum syndrome (p = 0.027; OR 2.8) is more likely to occur in women. Women with perineal descent younger than 50 years frequently present an increased descent during evacuation (81.8%), while those older than 50 years already have a low pelvic floor during rest (60.3%) (p < 0.001; OR 6.8), with little change in evacuation. Conclusion: Videodefecographic findings vary with age and gender.
