We performed this study to investigate defecographic findings in patients with fecal<br>incontinence and to compare these findings with age-matched asymptomatic controls.<br>Twenty patients with fecal incontinence and 20 asymptomatic subjects were included.<br>Videodefecography and pelvic electrophysiologic test were performed. There were no<br>significant differences on the presence of rectal wall changes such as rectocele, mucosal<br>prolapse, or incomplete evacuation, but intussusception was more common in patients<br>group. The anorectal angle were 112.8?6.2? 93.0?5.0? 118.8?6.3?at resting,<br>squeezing, and straining, respectively in controls, whereas 121.5?0.8? 110.8?2.2?<br>132.0?1.1? respectively in patients group. There were significant differences of<br>anorectal angle at squeezing and straining in patients group compared with controls(p<<br>0.05). Perineal descent was significantly decreased at squeezing in patients group<br>compared with controls(p<0.05). Anal canal width was signi(icantly widened in patients<br>group compared with controls(p<0.05). There were no differences in various<br>defecographic parameters depending on the presence of pudendal neuropathy. In<br>conclusion, defecographic findings in fecal incontinence showed more obtuse anorectal<br>angle, poorer perineal descent at squeezing, and widening of anal canal.<br>
