“…In some studies, the volume of the proximal stomach reached a peak value at about 2-5 min after ingestion of the test meal (Gilja et al, 1995;Gilja et al, 1996;Undeland et al, 1998;Lunding et al, 2006). In contrast, in the standard procedure using a barostat, the volume of the intragastric bag connected to the barostat increases every 2-3 min (Mearin et al, 1991;Kim et al, 2001).…”

“…In previous studies (Gilja et al, 1995;Gilja et al, 1996), US has been confirmed to be a simple and non-invasive technique for the assessment of gastric motility, including gastric accommodation. The authors of these reports chose the sagittal section and the maximal diameter in an oblique frontal section to evaluate gastric accommodation of the proximal stomach.…”

Background: Impaired gastric accommodation of the proximal stomach is one of the major pathophysiological mechanisms in functional dyspepsia (FD). However, no useful method exists for the clinical evaluation of this phenomenon. Aim: The aim of the present study was to establish a simple and non-invasive method for evaluating the accommodation reflex of the proximal stomach. Methods: Nine healthy subjects received up to 1,700 mL water (stepwise administration in 100-mL increments) using a nasogastric tube while they were in a supine position. To assess the meal-induced gastric accommodation reflex, we measured the cross-sectional area of the proximal stomach via ultrasonography (US) at 3-min intervals after administration of water. We also measured the pressure of the water column using the same tube. Then, we administrated up to 400 mL of water in 100-mL increments and measured the area of the proximal stomach in 44 FD patients with early satiation (the measurements were performed at intervals of 3-min), and we compared the results with those for 44 healthy subjects. Results: The incremental changes in the area of the proximal stomach corresponded well with the amount of water administered. The area of the proximal stomach increased, but the antral area and the intragastric pressure remained relatively stable. After administration of more than 100 ml water, the area of the proximal stomach in healthy subjects was significantly greater than that in FD patients.

“…Imaging-based volume methods include analysis of surface geometry of human stomach by real-time, 3D ultrasonography or, most recently, by 3D reconstruction of images acquired by ordinary ultrasonography assisted by magnetic scan-head tracking (53,78). In the most recent application of ultrasonography (54), an outline of the total stomach volume is visualized after ingestion of a liquid meal that serves as a contrast medium.…”

“…Real-time ultrasonography has been used to evaluate gastric emptying on the basis of the dynamic changes in the antral cross-sectional area in the axis of the superior mesenteric artery (9). Two-dimensional ultrasonography of the proximal stomach has been used to demonstrate volume changes after a meal (53) and its impairment in functional dyspepsia (55). Duplex Doppler has been applied to dynamically study transpyloric flow of liquid meals (61, 67); a short gush of duodenogastric reflux normally precedes the peristaltic closure of the pylorus; episodes of gastric emptying are defined as flow across the pylorus with a mean velocity of more than 10 cm/s, lasting Ͼ1 s (52).…”

First published January 15, 2009 doi:10.1152/ajpgi.90467.2008There is an array of tests available to measure gastric motility. Some tests measure end points, such as gastric emptying, that result from several different functions, whereas other tests are more specific and test only a single parameter, such as contractility. This article reviews the tests most commonly available in practice and research to evaluate in vivo the gastric functions of emptying, accommodation, contractility, and myoelectrical activity. The rationale for testing, the relative strengths and weaknesses of each test, and technical details are summarized. We also briefly indicate the applications and validations of the tests for use in experimental animal studies. contractility; emptying; accommodation; gastroparesis; dyspepsia ASSESSMENT OF THE MOTOR FUNCTIONS (motility) of the stomach is important in studies of gastric physiology and pathophysiology. Although not generally applied in gastroenterological practice, there is increasing use of tests to evaluate gastric function, particularly less invasive tests in clinical settings.There is an array of tests available to measure gastric motility.

A brief discussion is also provided for methods that have been used in animals to study motor functions of the stomach in animals. Tests to Evaluate Gastric Emptying of SolidsGastric emptying is a composite end point reflecting a variety of functions including gastric accommodation, the pressure gradient between the proximal and distal stomach, and antropyloroduodenal contractility and coordination. The trituration of solids and emptying of solid and liquid food from the stomach are arguably the most important physiological functions of the stomach. Abnormal gastric emptying, either accelerated at 1 h or delayed at 4 h, is among the factors that contribute to reporting of dyspepsia or the development of postprandial symptoms after meal challenge (35). For all tests of gastric motility and emptying, there are standard precautions (1): 1) Drugs affecting gastric motility (e.g., anticholinergics, narcotics, and prokinetics) are stopped for 48 h prior to the test, and the study is performed in the morning after an overnight fast. 2) Diabetic subjects should have a glucose level Ͻ275 mg/dl. 3) At the time the meal is ingested, Type 1 diabetic patients should receive half of their normal insulin dose.
