The comparison of two different esophageal motility catheters recording lower esophageal sphincter pressure [KARDIOOZOFAGEAL SFINKTER BASINCININ OLCULMESINDE IKI AYRI MOTILITE KATETERININ KARSILASTIRILMASI]

Lower esophageal sphincter (LES) has an asymmetric structure. Esophageal motility recording catheters usually have one side hole to measure the pressure and this may cause some errors in. the measurement of LES pressure. To get rid of this problem a new catheter that has four additional holes at the tip placed radially has been developed. In this study, to evaluate the advantage of this catheter, 23 male, 27 female patients' esophageal motility was recorded using the regular and newly developed catheter. Mean LES pressure measured with regular catheter (22.36 ± 16.6) was significantly higher than that recorded with radial catheter (15.23 ± 10.15) (p
