Combined multichannel intraluminal impedance and manometry (MII-EM) is a relatively new technique that allows simultaneous measurement of intraesophageal pressures and bolus transit. Combined MII-EM has the ability to identify what percentage of manometric normal/peristaltic, ineffective, and simultaneous swallows have complete or incomplete bolus transit. Predictors of normal bolus transit in patients with ineffective esophageal motility are the distal esophageal amplitude, the number of sites with low amplitudes, and the overall number of manometric ineffective contractions. Outcome studies are necessary to evaluate whether combined MII-EM is superior to traditional manometry in evaluating patients with nonobstructive dysphagia and in identifying patients at risk for developing dysphagia after antireflux surgery.
联合多通道腔内阻抗与测压技术（MII-EM）是一项相对较新的技术，它能够同时测量食管内压力和食团通过情况。联合MII-EM有能力确定测压正常/蠕动、无效及同步吞咽中食团完全或不完全通过的百分比。食管动力无效患者食团正常通过的预测因素包括食管远端振幅、低振幅部位数量以及测压无效收缩的总数。有必要开展结果研究，以评估联合MII-EM在评估非梗阻性吞咽困难患者以及识别抗反流手术后发生吞咽困难风险患者方面是否优于传统测压法。
