Abstract:
The method of defecography and its newly designed measuring ruler are described. There were 26 cases (27.08%) with abnormal findings in 96 subjects without defecatory disturbance. In 70 cases of normal value,the mean value of the anorectal angle(ARA) was 98.67?13.84 (62-123) at rest and 114.84?14.92 (94-151) during defecation. The distance between the anorectal junction (the upper part of anal canal) and the pubococcygeal line(DUAC) was 9.87?7.72 mm (-10-30 mm) at rest and 20.36?8.37 mm (-5-50 mm) during defecation. We suggest that the DUAC in Chinese should be ≤30 mm during defecation and the relative normal value of the parous women should be ≤35 mm. The length of the anal canal during defecation was 37.03?6 mm(25-50 mm), 39.67?5.47mm (30-50mm) in males and 34.33?4.19mm (27-50mm) in females. The distance between the sigmoid and the pubococcygeal line (DSPC) should be negative during defectation.
