基于HR-ARM与盆底sEMG检查的女性功能性排便障碍患者盆底功能异常特征分析
Pelvic floor dysfunction characteristics in female patients with functional defecation disorder based on HR-ARM and pelvic floor sEMG
摘要
Abstract
Objective To summarize the characteristics of pelvic floor dysfunction in female patients with functional defecation disorder(FDD)based on high-resolution anorectal manometry(HR-ARM)and pelvic floor surface electromyog-raphy(sEMG),in order to provide clinical guidance for treatment.Methods Sixty-four female patients with FDD were included in the FDD group,and 60 healthy female volunteers were recruited as the control group.All participants under-went HR-ARM and pelvic floor sEMG examinations.The parameters including anal resting pressure,maximum anal squeeze pressure,rectal expulsion pressure,residual anal pressure,minimum relaxation volume,rectal threshold for first sensation,rectal threshold for defecatory desire,rectal maximum tolerable threshold,anterior resting mean,anterior rest-ing variability,maximum value during rapid contraction,relaxation time during rapid contraction,mean value during tonic contraction,variability during tonic contraction,mean value during endurance contraction,variability during endurance contraction,posterior resting mean,and posterior resting variability were recorded and compared between these two groups.Results Compared with the control group,the FDD group showed significantly lower anal resting pressure,max-imum anal squeeze pressure,rectal expulsion pressure,and rectal threshold for first sensation(all P<0.05),while had higher residual anal pressure,rectal threshold for defecatory desire,and minimum relaxation volume(all P<0.05).In sEMG parameters,the FDD group demonstrated significantly lower anterior resting mean,maximum value during rapid contraction,mean value during tonic contraction,mean value during endurance contraction,and posterior resting mean(all P<0.05),but had higher variability during tonic contraction,variability during endurance contraction,and relaxation time during rapid contraction than the control group(all P<0.05).Conclusions Female patients with FDD present with multiple pelvic floor dysfunction characteristics,including inadequate anorectal dynamics,rectal hyposensitivity,de-creased pelvic floor muscle endurance,reduced stability,and impaired functional coordination.Combined application of HR-ARM and pelvic floor sEMG provides a more comprehensive evaluation of pelvic floor dysfunction in female FDD pa-tients.关键词
