目的:进一步探讨粪造影检查在功能性出口梗阻疾病的诊断价值及临床应用。材料与方法:对照组13例,均无排便障碍,其中男7例,女6例,年龄24~64岁,平均38岁。异常组25例,男3例,女22例,年龄6~81岁,平均39岁,病程2个月至26年。主要症状有排便困难,排不尽,腹胀等。大部分患者需借助泻药才能完成排便,严重者需手助。临床检查:10例(40%)可触及前突,7例(12%)有外痔,1例可扪及耻骨直肠肌不放松。造影方法:检查前1d用15g番泻叶冲服清洁肠腔,造影前2~3h口服稀钡200ml以观察有无小肠疝或下垂。造影时用?5%(w/u)硫酸钡300ml灌肠,一般灌至降结肠即可(本组16例为先检查大肠,后做排粪造影)。灌完钡后,将特制便桶置于X线机踏板上,让患者侧身坐在便桶上,调整便桶高度,使躯干与下肢成钝角,透视下分别摄取静坐、提肛及力排像,照片要求包括骶尾骨、肛门和耻骨联合。对照组结果:正常X线表现,静坐时,直肠充盈均匀,壁光滑,肛直角约为90~110°,肛上距<30mm(经产妇<35mm),肛门紧闭,提肛时,肛直角和肛上距均缩小,耻骨直肠肌切迹加深;力排时耻骨直肠肌切迹消失,肛直角增大(约为120~1400),肛管呈漏斗状开放,直肠大部或全部排空,直肠粘膜呈纵行,粗细较均匀。异常组:25例患者中以直肠前突和会阴下降最多见,各有12例,但多为合并存在。前突系 Objective: To further explore the diagnostic value and clinical application of fecal angiography in functional outlet obstruction diseases. Materials and Methods: The control group of 13 cases, no defecation disorders, including 7 males and 6 females, aged 24 to 64 years, mean 38 years. Abnormal group of 25 patients, 3 males and 22 females, aged 6 to 81 years, mean 39 years, duration of 2 months to 26 years. The main symptoms are defecation difficulties, row endless, bloating and so on. Most patients need to use laxatives to complete defecation, severe hand need help. Clinical examination: Ten cases (40%) could touch the protrusion, seven cases (12%) had external hemorrhoids, one case palpable puborectalis did not relax. Contrast method: check before 1d with 15g senna wash clean the intestine, 2 ~ 3h before angiography oral dilute barium 200ml to observe whether there is intestinal hernia or sagging. Contrast with? 5% (w / u) barium sulfate 300ml enema, the general irrigation to the descending colon can be (this group of 16 cases first check the large intestine, defecography). After filling barium, the special pail will be placed on the X-ray pedals, allowing the patient to sit sideways on the pail, adjusting the height of the pail, making the trunk and lower extremity an obtuse angle, respectively taking pictures of sit-ins and levator ani, Including sacrococcygeal, anal and pubic symphysis. The control group results: normal X-ray performance, sit-in, the rectum filling evenly, the wall smooth, anus right angle of about 90 ~ 110 °, anal distance <30mm (maternal <35mm), anal anus, anal anal, And anal spacing are narrowing, puborectalis notch deepening; force row when the puborectalis notch disappears, anal angle increases (about 120 ~ 1400), the anal canal was open funnel, most or all of the rectum emptying , Rectal mucosa was longitudinal, thicker and more uniform. Abnormal group: 25 cases of patients with rectal prolapse and perineum decreased the most common, each 12 cases, but mostly merged. Projection system
