直肠内脱垂和盆底痉挛的会阴下降测定

目的研究直肠内脱垂(internal rectal prolapse,IRP)和盆底痉挛(pelvic floor dyssynergia,PFD)的会阴下降。方法应用自制的会阴测量仪和排粪造影片测量IRP和PFD各32例的摒便时会阴下降。IRP中直肠粘膜脱垂(rectal mucosal prolapse,RMP)22例、直肠全层套叠(full thickness rectal intussusception,FTRI)10例。以同期18例无排便功能紊乱症状的健康人作对照组。结果会阴测量仪测定结果与排粪造影测量结果等效性检验具等效性(P<0.01)。IRP摒便时会阴大于对照组,且FTRI摒便时会阴下降大于RMP;PFD摒便时的会阴下降低于对照组(均为P<0.01)。结论IRP和PFD都存在摒便时会阴下降异常,前者表现为会阴下降幅度增大,后者表现为会阴下降不全。

Objective To determine the change of perinaeum descent in patients with internal rectal prolapse and pelvic floor dyssynergia. Methods The perinaeum descent was measured in 32 IRP patients, 32 PFD patients and 18 healthy volunteers with the device self-made and defecography graph. The IRP patients included 22 rectal mucosal prolapse patients and 10 full thickness rectal intussusception patients. Results The perinaeum descent measured by the device self-made equal to the results measured with defecography graph （P〈0.01）. The perinaeum descent in IRP proup was significantly higher than that in control group （P〈0.01）.The perinaeum descent in FTRI proup was significantly higher than that in RMP group （P〈0.01）. The perinaeum descent in PFD proup was significantly lower than that in control group （P〈0.01）. Conclusion The perinaeum descent in IRP and PFD were both abnormal, the former became high and the the latter became low.
