非器质性便秘分为缓慢通过(结肠无力)和盆底痉挛综合征(出口梗阻)两类。后者是正常盆底肌的一种功能异常。排便时,紧张的盆底肌收缩而不是松弛,肛管保持关闭状态,于是产生功能性的出口梗阻。74例功能性便秘患者,女性4倍于男性,年龄15～82岁(平均42岁),症状期1～38年(平均10年),排便频率1～21天1次(平均6.4天)。主要的主诉是腹痛、腹胀满、需使劲排便等。81%的患者使用泻药,39%需灌肠。6例有结肠手术史。全部患者均做排便造影,盆底肌电描记并服入20粒不透X线的标志物,每天摄片
Non-organic constipation is divided into slowly through (colon weakness) and pelvic floor spasm syndrome (outlet obstruction) two categories. The latter is a normal pelvic floor dysfunction. When defecating, the tension of the pelvic floor muscle contraction rather than relaxation, the anal tube to maintain the closed state, then produce a functional outlet obstruction. 74 cases of functional constipation patients, four times the number of women in men, aged 15 to 82 years (mean 42 years), symptoms 1-38 years (average 10 years), defecation frequency of 1 to 21 days 1 (average 6.4 days). The main complaint is abdominal pain, abdominal distention, need to stool and so on. 81% of patients use laxatives, 39% need enema. 6 cases had a history of colon surgery. All patients were done defecography, pelvic electromyography and into the 20 radiopaque markers, daily radiography
