排粪造影的检查方法和正常测量

Defecographical Method and Its Measurement

本文介绍了排粪造影的方法和排粪造影测量尺的制作。96例无排粪障碍者中有26例(27.08％)有异常表现。70例正常者的测量结果:肛直角:静坐98.67±13.84度;力排114.84±14.92度。肛上距:静坐9.87±7.72 mm;力排20.36±8.37 mm。建议将国人力排时肛上距的正常值定为<30 mm;对经产妇<35 mm为相对正常值。肛管长:力排时为37.03±6 mm。乙耻距:力排时应为负数。

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.
