Abstract:
Objective:To evaluate the gastric emptying in the patients with cholelithiasis and in the patients following cholecystectomy by ultrasonography.Methods:Thirty patients with cholelithiasis, 30 post-cholecystectomy patients and 30 healthy volunteers, of either sex, aged 18-64 yr, with body mass index of 18-30 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅰor Ⅱ, were selected and divided into cholelithiasis group (group CH), post-cholecystectomy group (group PC) and healthy volunteer group (group HV). The indigestion scores of the enrolled subjects in the past 3 months were assessed; the subjects took a semi-solid test meal (300 kcal) in the fasting state, and the cross-sectional area (CSA) of the gastric sinus was measured using ultrasound at fasting (T 0) and 5, 15, 30, 45, 60, 90 and 120 min after the test meal was taken (T 1-7). The gastric emptying fraction at T 5, 6 was calculated. The gastric half-emptying time and remaining area of the gastric sinus at T 7 were also calculated. Results:Compared with group HV, dyspepsia scores were significantly increased within the past 3 months ( P<0.05), the CSA of the gastric sinus was increased at T 3-7, the gastric emptying fraction was decreased at T 5-6, the gastric half-emptying time was prolonged, and the remaining area of the gastric sinus was increased at T 7 in group CH and group PC ( P<0.05). Compared with group CH, the CSA of the gastric sinus was significantly increased at T 4-7, the gastric emptying fraction was decreased at T 5, 6, the gastric half-emptying time was prolonged, and the remaining area of the gastric sinus was increased at T 7 in group PC ( P<0.05). Conclusions:Gastric emptying time is longer in the patients with cholelithiasis and in the patients following cholecystectomy than in healthy subjects and is further prolonged after cholecystectomy in the patients.
