BACKGROUND: The upper esophageal sphincter is composed of striated muscle. The stress of intubation and the need to inhibit dry swallows during an esophageal manometry test may lead to variations in basal pressure of this sphincter. Upper esophageal sphincter is usually only studied at the final part of the test. Was observed during the performance of high resolution manometry that sphincter pressure may vary significantly over the course of the test. AIM: To evaluate the variation of the resting pressure of the upper esophageal sphincter during high resolution manometry. METHODS: Was evaluated the variation of the basal pressure of the upper esophageal sphincter during high resolution manometry. Were reviewed the high resolution manometry tests of 36 healthy volunteers (mean age 31 years, 55% females). The basal pressure of the upper esophageal sphincter was measured at the beginning and at the end of a standard test. RESULTS: The mean time of the test was eight minutes. The basal pressure of the upper esophageal sphincter was 100 mmHg at the beginning of the test and 70 mmHg at the end (p<0.001). At the beginning, one patient had hypotonic upper esophageal sphincter and 14 hypertonic. At the end of the test, one patient had hypotonic upper esophageal sphincter (same patient as the beginning) and seven hypertonic upper esophageal sphincter. CONCLUSION: A significant variation of the basal pressure of the upper esophageal sphincter was observed in the course of high resolution manometry. Probably, the value obtained at the end of the test may be more clinically relevant.

Abstract Introduction The number of pressure measurements that need to be recorded using high-resolution manometry (HRM) for the accurate evaluation of pharyngeal function is not well established. Objective The purpose of this study is to clarify the number of swallows required to obtain an accurate pharyngeal manometric profile of a person. Methods Forty healthy adults performed a dry swallow and bolus swallows using 3-, 5-, or 10 ml of water and underwent measurements using the Starlet HRM system. Each subject underwent 10 swallows for each of the four bolus volume conditions. Results The mean of up to seven measurements of maximum pre-swallow upper esophageal sphincter pressure with 10 ml of swallow was close to the mean of up to eight measurements in 95% of the subjects. Similarly, the rate of change of the average for the eighth and ninth measurements and the rate of change for the average of the ninth and tenth measurements were less than 5%. When the other parameters were similarly measured up to the sixth measurement, no major change in the average value was observed even if more measurements were taken. Conclusion A minimum of six measurements are required, and seven swallows are sufficient for evaluating the pharyngeal manometric profile of a single person. This number of measurements can be a useful criterion when performing HRM measurements on individual subjects.

Pharyngeal Swallowing

Objectives This study aimed to demonstrate the feasibility of a novel high-resolution manometry (HRM) system, and to establish normal values of swallowing pressures along the velopharynx and upper esophagus. Methods 33 asymptomatic adult Japanese controls were studied. A solid-state HRM assembly with 36 circumferential sensors spaced 1 cm apart was positioned to record pressures during swallowing from the velopharynx to the upper esophagus. The maximum values of the swallowing (dry and 5 ml of water) pressures at velo, meso-hypopharynx, and at the upper esophageal sphincter (UES) were measured. The resting UES pressure, the length of the part in the cervical esophagus showing the resting UES pressure, and the distance from the nostril to the above-mentioned points of pressure were also measured. Results The maximum value of dry and water swallowing pressures at the velopharynx, meso-hypopharynx and UES, and the distances from the nasal vestibulum to each point were 132.3±61.3 (mmHg, mean ± standard deviation), and 146.5±77.5, 171.6±52.0, and 176.3±74.4, 163.5±70.6, and 239.3±80.1, and 9.8±1.2 (cm), and 9.8±1.3, 13.6±1.6, and 13.7±1.5, 17.0±1.9 and 17.1±1.6, respectively. The maximum value of the resting USE pressure, the length of the part in the cervical esophagus showing the resting USE pressure, and the distance from the nostril to the mid-point of the length of the resting UES pressure were 66.6±28.1 mmHg, 3.8±0.7 cm, and 18.2±1.6 cm, respectively. Conclusions The present study provides anatomical and physiological information about normal swallowing along the velopharynx and upper esophagus, which will be an aid to future clinical and investigative studies.
