| 1 | Effects of anatomical position on esophageal transit time:A biomagnetic diagnostic technique显示文摘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; 90o, 45o and 0o, 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 90o, 45o and 0o, 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. | Teodoro Cordova-Fraga Modesto Sosa Carlos Wiechers Jose Maria De la Roca-Chiapas Alejandro Maldonado Moreles Jesus Bernal-Alvarado Raquel Huerta-Franco | 2008 | World Journal of Gastroenterology2008，14，37： | 1 |
