Conventional oesophageal manometry and intraluminal electrical impedance measurement were simultaneously applied in eight healthy volunteers to study the effect of wet and semisolid bolus viscosities on oesophageal motility and bolus transit. Contraction front velocity measured by electrical impedance and manometry were identical for wet and semisolid swallows and highly associated. Bolus front velocity as measured by electrical impedance was significantly faster than contraction front velocity in both wet and semisolid swallows. Bolus front velocity during semisolid swallows was significantly slower compared to wet swallows. It is concluded that intraluminal electrical impedance measurement is a reliable technique to detect oesophageal motility as well as to differentiate between transit of wet and semisolid bolus consistencies.
对8名健康志愿者同时进行传统食管测压和腔内电阻抗测量，以研究湿食团和半固体食团粘度对食管动力和食团通过的影响。通过电阻抗和测压测量的湿食团和半固体食团吞咽时的收缩波前沿速度相同且高度相关。通过电阻抗测量的食团前沿速度在湿食团和半固体食团吞咽时均显著快于收缩波前沿速度。半固体食团吞咽时的食团前沿速度显著慢于湿食团吞咽时。结论是，腔内电阻抗测量是检测食管动力以及区分湿食团和半固体食团通过情况的可靠技术。
