Dysphagia is a common reason for referral for investigations of oesophageal motility. Impedance measurement has now been incorporated into commercially available diagnostic manometry systems for more than a decade. This innovation, which offered the ability to record patterns of bolus transport without the need for simultaneous radiology, has for the most part failed to live up to expectations, offering few additional diagnostic insights. This review examines the potential pitfalls related to how impedance patterns are currently analysed and introduces and discusses the new concept of pressure-flow analysis integrating pressure and impedance measurements to derive new metrics linked to the pressures occurring within and around the bolus as it is being transported.
吞咽困难是进行食管动力检查的常见原因。阻抗测量技术已经在商业上可用的诊断测压系统中应用了十多年。这项创新技术提供了在无需同时进行放射学检查的情况下记录食团输送模式的能力，但在大多数情况下未能达到预期，并未提供更多的诊断见解。本文回顾了与目前分析阻抗模式相关的潜在问题，并介绍和讨论了新的压力-流量分析概念，该概念将压力和阻抗测量相结合，以得出与食团输送过程中内部和周围压力相关的新指标。
