Conventional videodefecography: Pathologic findings according to gender and age

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.
