ABSTRACT
Fecal incontinence (FI) is often underreported and underestimated in men. Our aims were to clarify the causes and the physiological characteristics of FI in men and to underline the differences between etiological and physiological factors in men and women diagnosed with FI. The study cohort encompassed 200 men and 200 women who underwent anatomical and physiological evaluation for FI in a tertiary referral center specializing in pelvic floor disorders. All patients underwent endoanal ultrasound and anorectal manometry. Evacuation proctography was performed in some patients. Demographic, medical, anatomical, and physiological parameters were compared between the two study groups. Urge incontinence was the most frequent type of FI in both genders. In men, anal fistula, history of anal surgeries, rectal tumors, and pelvic radiotherapy were common etiologic factors, whereas history of pelvic surgeries was more common in women. Associated urinary incontinence was reported more frequently by women. External anal sphincter defects, usually anterior, were more common in women (M 1.5%, F 24%, P < 0.0001), whereas internal anal sphincter defect prevalence was similar in men and women (M 6%, F 12%, P = 0.19). Decreased resting and squeeze pressures were less common in men (M 29%, F 46%, P < 0.0001 M 44%, F 66%, P < 0.0001). The incidence of rectal hyposensitivity was higher in men (M 11.1%, F 2.8%, P < 0.0001), whereas rectal hypersensitivity was higher in women (M 5.8%, F 10.8%, P < 0.0001). Anorectal dyssynergia was more common in men (M 66%, F 37%, P < 0.0001). Significantly different etiological factors and physiological characteristics for FI were found in men. Acknowledging these differences is significant and may yield better treatment options.NEW & NOTEWORTHY Fecal incontinence (FI) in men has different etiological factors when compared with women. The prevalence of internal anal sphincter defect among men with FI was similar to women. Different manometric measurements were found among men with FI decreased anal pressures were less common among men, whereas rectal hyposensitivity and anorectal dyssynergia were more common among men.
