ABSTRACT
AIM:
To study the esophageal transit time (ETT) and compare its mean value among three anatomical inclinations of the body; and to analyze the correlation of ETT to body mass index (BMI).METHODS:
A biomagnetic technique was implemented to perform this study (1) The transit time of a magnetic marker (MM) through the esophagus was measured using two fluxgate sensors placed over the chest of 14 healthy subjects; (2) the ETT was assessed in three anatomical positions (at upright, fowler, and supine positions; 90 degrees , 45 degrees and 0 degrees , respectively).RESULTS:
ANOVA and Tuckey post-hoc tests demonstrated significant differences between ETT mean of the different positions. The ETT means were 5.2 +/- 1.1 s, 6.1 +/- 1.5 s, and 23.6 +/- 9.2 s for 90 degrees , 45 degrees and 0 degrees , respectively. Pearson correlation results were r = -0.716 and P < 0.001 by subjects' anatomical position, and r = -0.024 and P > 0.05 according the subject's BMI.CONCLUSION:
We demonstrated that using this biomagnetic technique, it is possible to measure the ETT and the effects of the anatomical position on the ETT.
