Defecatory difficulties may be a source of great distress to patients. Normal defecation requires the coordination of abdominal and pelvic muscles. Throughout the last decade, many studies have demonstrated various and often mixed abnormalities of these mechanisms. Pathophysiological studies are able to determine, in a specific patient, the most probable causes of the obstructive symptom. Progress in the management of such disorders can only be achieved by understanding their pathophysiology.
排便困难可能给患者带来极大困扰。正常排便需要腹部和盆底肌肉的协调配合。在过去十年间，许多研究已证实这些机制存在多种且常常是混合性的异常。病理生理学研究能够确定特定患者中梗阻症状最可能的病因。只有了解这些疾病的病理生理学，才能在其治疗上取得进展。
