Abstract
INTRODUCTION
Increased intra-abdominal pressure in patients with elevated body mass index (BMI) may affect measurements of esophagogastric junction (EGJ) opening.
METHODS
Findings from adult patients who underwent both impedance planimetry with functional luminal imaging probe (FLIP) and high-resolution manometry (HRM) were compared by BMI.
RESULTS
Among patients with no EGJ outflow obstruction on HRM, abnormal EGJ classifications on FLIP were more common among those with elevated than normal BMI (61.1% vs 31.6%, P = 0.037).
DISCUSSION
Discordant results between FLIP and HRM on EGJ opening are more common in patients with elevated BMI. Body composition may impact EGJ function and measures on current testing modalities.
摘要
引言
体重指数（BMI）升高的患者腹内压增加可能会影响食管胃交界部（EGJ）开口的测量。
方法
通过BMI比较接受功能性管腔成像探头（FLIP）阻抗平面测量和高分辨率测压（HRM）的成年患者的结果。
结果
在HRM检查中无EGJ流出道梗阻的患者中，FLIP上EGJ异常分类在BMI升高的患者中比正常BMI患者更常见（61.1%对31.6%，P = 0.037）。
讨论
在BMI升高的患者中，FLIP和HRM在EGJ开口方面的不一致结果更为常见。身体组成可能会影响EGJ功能以及当前检测方式的测量结果。
