Background/Aims: False positive results are common in the diagnosis of pelvic floor dyssynergia (PFD) using anorectal physiologic studies (ARPS). The aim of this study was to determine the effects of psychosocial factors on false positive results of ARPS for the diagnosis of PFD in healthy volunteers.
Methods: Forty healthy subjects were enrolled. All subjects underwent a complete self-rated inventory assessing psychological distress (SCL-90-R), personal history, anorectal manometry, balloon expulsion testing, electromyography, video-defecography and evaluation of colonic transit time. We compared a variety of psychosocial parameters between subjects with abnormal and normal results of the ARPS.
Results: There was a tendency to have a more somatizing personality in subjects with changes in the anorectal angle less than 15 degrees during straining compared to subjects with a change in the anorectal angle more than 15 degrees (p=0.092). However, there were no other differences in psychosocial factors when compared to the results of the anorectal physiologic study. A group with suggestive pelvic floor dyssynergia by video-defecography had more college graduates than the normal group (p<0.05). Also, this group had a greater income than the normal group (p<0.05).
Conclusions: Our findings suggest that psychological factors do not affect the results of ARPS. However, socioeconomic factors affect the results of defecography in the diagnosis of PFD in healthy subjects. (Kor J Neurogastroenterol Motil 2006;12:48-54)
