Fecal incontinence is a physically and psychologically disabling condition that affects millions of Americans, especially those over the age of 65 years. The pathophysiology is often multifactorial, with decreased anorectal sensation, reduced rectal compliance. anal sphincter dysfunction, altered stool consistency and immobility playing significant roles. A detailed history and a thorough physical examination are always necessary in patients with fecal incontinence and physiologic tests, including anorectal manometry, cinedefecography and electromyography, may be required for proper diagnosis and treatment. In most patients fecal incontinence is initially treated with conservative measures, such as biofeedback training or alteration of the stool consistency (if appropriate). If conservative management fails, surgical intervention, such as sphincteroplasty or gracilis muscle transposition, may be considered.
大便失禁是一种会对身体和心理造成损害的病症,影响着数百万美国人,尤其是65岁以上的人群。其病理生理学通常是多因素的,肛门直肠感觉减退、直肠顺应性降低、肛门括约肌功能障碍、粪便稠度改变和活动不便都起着重要作用。对于大便失禁患者,详细的病史和全面的体格检查总是必要的,可能还需要进行生理测试,包括肛门直肠测压、排粪造影和肌电图检查,以进行正确的诊断和治疗。在大多数患者中,大便失禁最初采用保守措施治疗,如生物反馈训练或改变粪便稠度(如适用)。如果保守治疗失败,可以考虑手术干预,如括约肌成形术或股薄肌移位术。
