排粪造影是近年来在国内外逐渐开展的一项对诊断排粪障碍的重要检查手段。本文介绍了用钡悬液灌肠同时置浸钡棉条显示肛管、肛缘涂钡标记进行排粪造影的检查方法。对肛直角、功能性肛管长度、骶耻线及会阴下降度等的测量方法进行了改进。报告了我们对100例无排粪障碍的健康志愿者的排粪造影片所测量的结果,并探讨了国人排粪造影的正常值,同时指出直肠前突可发生在无排粪障碍的女性,其发生率与顽固性便秘的患者几乎相同,所以在排粪造影中发现有直肠前突的患者,除仔细阅读排粪造影片外,尚须行盆底肌电图等检查,以明确导致顽固性便秘的原因。
Defecation radiography in recent years at home and abroad gradually carried out an important diagnostic tool for defecation obstacles. This article describes the use of barium suspension enema at the same time set barium impregnated cotton sliver shows anal canal, barium labeled anal marker for defecography. The anal angle, functional anal canal length, sacral line and perineal descending degree of measurement methods have been improved. We report the results of the fecal screenings of 100 volunteers without defecation disorders and discuss the normal values of defecography in our country. We also point out that rectocele can occur in females without defecation disorders, The incidence of refractory constipation and refractory patients are almost the same, so in defecography found in patients with rectocele, in addition to carefully read the video of defecation, the need to line pelvic floor electromyography and other tests in order to clearly lead to stubborn Cause of constipation.
