Whether used as the primary diagnostic test or reserved as a problem-solving examination, fluoroscopic defecography (FD) remains an important tool in the workup and treatment of defecatory disorders. FD is a well-established, simple, and rapid examination that most closely resembles the actual process and position that a patient uses to enable defecation and provides both qualitative and quantitative information on the defecatory process. FD is indicated when re-creating the act of defecation is necessary, especially in patients with symptoms of obstructed defecation and where symptoms do not correlate with prior examinations such as MRI. Also, FD may help the patient understand the severity of their condition, better informing them of the structural and functional pathology, and aid in discussions with the surgeon regarding plans for treating their complex pelvic floor and defecatory problems. This review provides an up-to-date, comprehensive summary of FD and describes the indications for, techniques of, and common pathology encountered.
无论是作为主要的诊断测试还是保留为解决问题的检查，荧光透视排粪造影（FD）仍然是排便障碍诊治中一个重要的工具。FD 是一种成熟的、简单的、快速的检查，最接近患者实际排便的过程和姿势，提供了排便过程的定性和定量信息。当需要重现排便动作时，需要进行 FD，特别是在有阻塞性排便症状的患者中，且症状与 MRI 等先前的检查不相符时。此外，FD 可以帮助患者了解自己病情的严重程度，更好地了解他们的结构和功能病理，并有助于与外科医生讨论治疗他们复杂的盆底和排便问题的计划。本综述提供了 FD 的最新、全面的概述，描述了 FD 的适应证、技术以及常见的病理表现。
