Symptoms such as a feeling of incomplete evacuation, straining, absence of the call to stool, anal blockage, or digitation suggest the presence a functional defecation disorder. As symptoms do not distinguish between patients with and without functional defecation disorder, Rome IV criteria recommend that this disorder is diagnosed when two of three tests are positive: balloon expulsion test (BET), anorectal manometry (ARM), and defecography. However, previous studies have demonstrated that the agreement among these tests is limited. In this issue of Neurogastroenterology and Motility, Sharma et al tested the hypothesis that conducting the ARM in a seated position would increase the diagnostic accuracy of the test in discriminating between patients with normal and prolonged BET. This minireview discusses the current knowledge on the role of the techniques to diagnose defecation disorder and the potential role of the ARM in a seated position.

模拟疏散期间的坐位肛门直肠测压：生理练习还是新的临床有用的诊断测试？

症状如排便不完全、用力、没有排便、肛门阻塞或指状指征等症状表明存在功能性排便障碍。由于症状不能区分有无功能性排便障碍的患者，罗马 IV 标准建议在以下三个测试中的两个为阳性时诊断该疾病：球囊排出测试 (BET)、肛门直肠测压 (ARM) 和排便造影。然而，先前的研究表明，这些测试之间的一致性是有限的。在本期 Neurogastroenterology and Motility 中，Sharma 等人检验了以下假设：在坐姿下进行 ARM 将提高测试在区分正常和延长 BET 患者方面的诊断准确性。
