Examination for fecal incontinence is performed in order to evaluate the condition of each patient. As there is no single method that perfectly assesses this condition, there are several tests that need to be conducted. These are as follows: anal manometry, recto anal sensitivity test, pudendal nerve terminal motor latency, electromyogram, anal endosonography, pelvic magnetic resonance imaging (MRI) scan, and defecography. In addition, the mental and physical stress most patients experience during all these examinations needs to be taken into consideration. Although some of these examinations mostly apply for patients with constipation, we hereby describe these tests as tools for the assessment of fecal incontinence. Conservative therapies for fecal incontinence include diet, lifestyle, and bowel habit modification, pharmacotherapy, pelvic floor muscle training, biofeedback therapy, anal insert device, trans anal irrigation, and so on. These interventions have been identified to improve the symptoms of fecal incontinence by determining the mechanisms resulting in firmer stool consistency; strengthening the pelvic floor muscles, including the external anal sphincter; normalizing the rectal sensation; or periodic emptying of the colon and rectum. Among these interventions, diet, lifestyle, and bowel habit modifications and pharmacotherapy can be performed with some degree of knowledge and experience. These two therapies, therefore, can be conducted by all physicians, including general practitioners and other physicians not specializing in fecal incontinence. However, patients with fecal incontinence who did not improve following these initial therapies should be referred to specialized institutions. Contrary to the initial therapies, specialized therapies, including pelvic floor muscle training, biofeedback therapy, anal insert device, and trans anal irrigation, should be conducted in specialized institutions as these require patient education and instructions based on expert knowledge and experience. In general, conservative therapies should be performed for fecal incontinence before surgery because its pathophysiologies are mostly attributed to benign conditions. All Japanese healthcare professionals who take care of patients with fecal incontinence are expected to understand the characteristics of each conservative therapy, so that appropriate therapies will be selected and performed. Therefore, in this chapter, the characteristics of each conservative therapy for fecal incontinence are described.
进行大便失禁检查是为了评估每位患者的病情。由于没有一种单一的方法能完美评估这种情况,因此需要进行多项检查。具体如下:肛门测压、直肠肛门敏感性测试、阴部神经终末运动潜伏期、肌电图、肛门腔内超声检查、盆腔磁共振成像(MRI)扫描以及排粪造影。此外,还需要考虑大多数患者在所有这些检查过程中所经历的精神和身体压力。尽管其中一些检查主要适用于便秘患者,但我们在此将这些检查描述为评估大便失禁的工具。大便失禁的保守治疗方法包括饮食、生活方式和排便习惯调整、药物治疗、盆底肌肉训练、生物反馈疗法、肛门插入装置、经肛门冲洗等。已确定这些干预措施可通过确定导致大便质地更坚实的机制、加强包括肛门外括约肌在内的盆底肌肉、使直肠感觉正常化或使结肠和直肠定期排空来改善大便失禁症状。在这些干预措施中,饮食、生活方式和排便习惯调整以及药物治疗可以在一定程度的知识和经验基础上进行。因此,包括全科医生和其他非大便失禁专科医生在内的所有医生都可以实施这两种治疗方法。然而,经过这些初始治疗后仍未改善的大便失禁患者应转诊至专科医院。与初始治疗相反,包括盆底肌肉训练、生物反馈疗法、肛门插入装置和经肛门冲洗在内的专科治疗应在专科医院进行,因为这些治疗需要基于专业知识和经验的患者教育和指导。一般来说,由于大便失禁的病理生理学大多归因于良性疾病,所以在手术前应先进行保守治疗。所有照顾大便失禁患者的日本医疗保健专业人员都应了解每种保守治疗的特点,以便选择并实施适当的治疗方法。因此,在本章中,将描述大便失禁每种保守治疗的特点。
