    Abstract:
    BACKGROUND: Ingestion of cold fluids may induce pain in patients with esophageal motility disorders. Hot fluids, on the other hand, may help to relieve pain. We studied changes in esophageal motility as a variable of water bolus temperature using high-resolution manometry (HRM) in healthy human. METHODS: Thirty-two healthy subjects were recruited at Kosin University Hospital. HRM was performed in a sitting position, with room temperature (RT, 25 °C), hot (45 °C), and cold (2 °C) water swallowed in that order. This exam included single swallowing (10 swallows of 5 mL water, 30 s intervals) and multiple water swallows (MWS; 100 mL water within 30 s). KEY RESULTS: In the single swallowing, hot water caused a decrease in lower esophageal sphincter (LES) residual pressure (5.87 ± 4.20 mmHg vs 7.45 ± 4.17 mmHg (RT), p = 0.001) and duration of esophageal body (EB) contraction (3.01 ± 0.80 s vs 3.15 ± 1.16 s (RT), p = 0.009). Cold water caused an increase in the duration of EB contraction (3.52 ± 0.87 s vs 3.15 ± 1.16 s (RT), p = 0.001) and a decrease in contractile front velocity (CFV) (4.43 ± 1.50 cm/s vs 4.90 ± 2.53 cm/s (RT), p = 0.007). Similarly, in the MWS, hot water caused a decrease in the duration of EB contraction (12.95 ± 5.02 s vs 16.33 ± 5.94 s (RT), p = 0.024) and an increase in the amplitude of EB contraction (114.27 ± 83.36 mmHg vs 82.70 ± 46.77 mmHg (RT), p = 0.007). Cold water caused an increase in the duration of EB contraction (27.38 ± 2.89 s vs 16.33 ± 5.94 s (RT), p = 0.03) and a decrease in the amplitude of EB contraction (51.68 ± 33.94 mmHg vs 82.70 ± 46.77 mmHg (RT), p = 0.001). CONCLUSIONS & INFERENCES: This study showed changes in esophageal motility to be dependent on water temperature. Especially, MWS showed clear changes in esophageal motility at different temperatures of water.
