Investigators assess the gastric contents by ultrasonography in fasted patients undergoing cholecystectomy.
Investigators evaluate the gastric volume through cross sectional area and amount of clear fluid using Perlas grade by ultrasound in the supine and right lateral position of fasted patients undergoing cholecystectomy. Full stomach is regarded if solid gastric contents are detected or clear fluid is more than 1.5 ml/kg. The frequency of full stomach will be analyzed.
