肛管直肠压力测定诊断盆底失弛缓综合征的临床研究

目的通过肛管直肠压力测定研究盆底失弛缓综合征(unrelaxed pelvic floor syndrome，UPFS)的肛管直肠动力学变化。方法对天津市人民医院2006年1月至2007年8月收治的有便秘症状并经排粪造影诊断为UPFS的57例病人用肛管直肠压力测定仪行肛管直肠压力测定。以无排便功能紊乱症状的30名健康志愿者作对照组。结果与对照组相比, UPFS病人肛管静息压直肠静息压差异无统计学意义(P>005),肛管最大收缩压差异具有统计学意义(P<001)，力排时直肠肛管压力差差异具有统计学意义(P<001),且此压力差为负值,引起直肠初始感觉和初始便意感觉的容积及最大耐受容积差异均有统计学意义(P<001)。结论UPFS病人存在明显的直肠感觉功能下降和盆底肌肉协调运动障碍。

Clinical research of anorectal manometry in unrelaxed pelvic floor syndrome

Objective To explore the changes of anorectal manometry in unrelaxed pelvic floor syndrome(UPFS).Methods Anorectal pressure,rectal evacuation were measured in 57 UPFS patients(UPFS group) and 30 healthy volunteers(control group) between January 2006 and August 2007 at the People's Hospital of Tianjin City.Results The anal resting pressure in UPFS group had no significant difference with that in control group(P>0.05).The anal maximum contractive pressure in UPFS group was higher than that in control group(P<0.01).The rectal anal pressure difference when straining to defecate in UPFS group was negative and lower than that in control group(P<0.01).The minimum rectal volumes to first sensation and desire to defecate in UPFS group were higher than those in control group(P<0.01).Conclusion There are decreased rectal sensation and pelvic floor muscle dysfunction in patients with UPFS.
