Abstract

BACKGROUND/AIMS
The aim of this study was to evaluate the effect of meal temperature on gastroduodenal motility and gastric myoelectrical activity. For eight healthy volunteers, we performed antroduodenal manometry and electrogastrography after ingestion of either a cold or a warm test meal.
METHODS
This study was performed in 8 healthy male volunteers aged 21-35 years, who had no history of gastrointestinal diseases or taking medication. On each study day, the subjects underwent simultaneous antroduodenal manometry and cutaneous electrogastrography (EGG). The test meal (516 kcal, 4C degrees or 50C degrees) consisted of 20.0 gm protein, 20.8 gm fat, and 62.3 gm carbohydrate, and was given on phase I of the migrating motor complex. The each test meal was consumed within ten minutes. RESULTS: Differences in the power ratio and the number of dysrhythmias on EGG findings were not found between the 4C degrees and 50C degrees meals. During the first postprandial 10 min, the peak frequency (cpm) was higher after the ingestion of the 50C degrees meal (3.4+/-0.3) than after the ingestion of the 4C degrees meal (2.7+/-0.2)(p<0.05). There were no differences between the 4C degrees meal and 50C degrees meal in the frequency, amplitude, and motility indices of the antral and duodenal contractions. CONCLUSIONS: The meal temperature affected gastric myoelectrical activity by postprandial transient shift in frequency. However, differences in antroduodenal motility were not associated with meal temperature.
