摘　　要：控便功能是指当产生便意时,可以辨别粪便干稀急缓,并能正常控制其排出的能力。因一些意外因素,如盆底功能障碍、某些先天性疾病及盆腔恶性肿瘤术后会导致此功能受损,而严重影响患者的生活质量。近年来,诸多国内外学者对控便功能障碍患者进行了临床和影像学研究,能够认知控便功能受损的造成因素及改善方法,对于术前术后制定治疗方案具有重要的临床价值,是目前研究的焦点。以MRI从影像学角度为阐述其障碍发生的可能机制及改善预后提供一定依据。因此,笔者对近年来控便功能障碍的MRI研究进展做简要综述。The function of defecation control refers to the ability to distinguish the dryness of stool and control its discharge normally when it produces the meaning of defecation.This function will be impaired after operation due to some unexpected factors,such as pelvic floor dysfunction,some congenital diseases and pelvic malignant tumors,which seriously affect the quality of life of patients.In recent years,many scholars at home and abroad have carried out clinical and imaging studies on patients with defecation dysfunction,which can recognize the causes and improvement of defecation dysfunction,which has important clinical value for preoperative and postoperative treatment.It is the focus of the current research.From the perspective of imaging,MRI provides a basis for explaining the possible mechanism of its disorders and improving the prognosis.Therefore,the author briefly reviews the research progress of MRI in defecation control dysfunction in recent years.
