Abstract

PURPOSE: Defecography is a technique of examining the rectum and anal canal by using fluoroscopy duringdefecation. This study was done to determine the range of normal findings of defecography in young asymptomaticKorean volunteers. MATERIALS AND METHODS: Twenty-nine asymptomatic young volunteers underwent defecography.Anorectal angle, perineal descent, length and width of anal, rectocele, rectal intussusception and incontiencewere evaluated. RESULTS: The range of anorectal angle was 82 -149 in resting state, compared to the 63 -116 insqueezing state, and 95 -116 in straining state respectively. The pelvic floor in straining state descended onaverage of 1.62cm from the inferior margin of ischial tuberosity that its broad range of position from -5.2cm to0.8cm implies a wide variation of anorectal angle and perineal descent. Mild degree of rectocele with less than2cm of depth was found in 12 out of 29 cases. Rectal intussusception was noted in six and rectal incontinence wasseen in one case. Formation of rectocele and intussusception during defecation was common in asymptomatic youngvolunteers. CONCLSION: The wide range of defecographic measurements warrants the necessity of other complementarystudies on anorectal function to improve the diagnostic accuracy. The interpretation of defecographic measurementshould therefore be made with caution and should not be used as the sole criteria for seliction of treatmentmodality.
