目的 :研制用于排粪造影的仿真排粪造影剂及配套用的注推器和专用软肛管 ,为临床提供诊断和治疗的依据。方法 :选择无便秘症状的健康志愿者 35例 (简称正常组 ) ,男 14例 ,女 2 1例 ,平均年龄 44岁。采用了钡悬液排粪造影检查 (简称 1法 )及仿真排粪造影检查 (简称 2法 )双法对比观察。便秘病人 6 7例 (简称便秘组 ) ,男 19例 ,女 48例 ,平均年龄 47岁。也进行了双法对比观察。 1法造影剂的配方为 2 0 0 %的硫酸钡悬液 40 0 ml。 2法配方 :包括硫酸钡粉剂、麦麸及白芨粉。结果 :正常组经 1法、2法观察 18例女性有轻度直肠前凸 ,占 5 1% ,余未见异常。1法、2法对比力排状态下肛直角有显著性差异。便秘组中 5例无异常发现 ,有异常发现的 6 2例病人中盆底痉挛异常者 2 3例 (简称痉挛组 ) ,占 34% ,其中男 10例 ,女 13例。盆底松驰异常者 39例 (简称松驰组 ) ,占5 8% ,其中男 5例 ,女 34例。痉挛组 :肛直角静息状态下 1法、2法测量结果相同 ,力排状态下不同。肛门上距静息状态下 1法、2法相同 ,力排状态下不同。松驰组 :肛直角静息状态下 1法、2法测量结果相同 ,力排状态下不同。肛门上距静息状态下 1法、2法相同 ,力排状态下相同。结论 :本造影方法可准确区别直肠粘膜脱垂和全套叠 ,正确诊断耻骨直肠肌痉挛
Objective: To develop a simulation defecography contrast agent for defecography and an accompanying injection device and dedicated soft anal canal to provide the basis for clinical diagnosis and treatment. Methods: 35 healthy volunteers without symptoms of constipation (abbreviated as normal group) were selected. There were 14 males and 21 females with an average age of 44 years. The phlegm suspension defecography (abbreviated as the 1 method) and the simulated defecography (abbreviated as the 2 method) were used for double observation. There were 67 patients with constipation (abbreviated as constipation group), 19 males and 48 females, with an average age of 47 years. Double-contrast observations were also performed. The formula 1 contrast agent was a 20% 00% barium sulfate suspension 400 ml. Formula 2: Including barium sulfate powder, wheat bran and white lotus root powder. RESULTS: In the normal group, 18 cases had mild rectal lordosis, which accounted for 5 1%, and no abnormality was observed. There was a significant difference in the anal angle between the 1 and 2 methods in the contrast force row. In the constipation group, no abnormalities were found in 5 cases. Of the 62 cases with abnormal findings, 23 cases were abnormal in the pelvic floor hernia (referred to as the phlegm group), accounting for 34%, including 10 males and 13 females. 39 cases of abnormal pelvic floor relaxation (abbreviated as relaxation group) accounted for 58%, including 5 males and 34 females. The squatting group: The measurement results of the 1st and 2nd methods in the resting state of the anal squamous angle are the same, and the state of force is different. On the anus, the method of 1 and 2 is the same from resting state, and the state of force is different. Relaxation group: The measurement results of the 1st and 2nd method in the resting state of the anal angle are the same, and the state of force is different. On the anus, it is the same as the 1 method and the 2 method from the rest state, and the force is in the same state. Conclusion: This angiography method can accurately distinguish rectal mucosal prolapse and full stack and correctly diagnose puborectal muscle spasm.
