We correlated the amount of gastric fluid identified by sonography in 143 fasting patients with the presence of duodenal ulcer disease and gastric-outlet obstruction as seen on barium studies. Unselected consecutive patients who were referred for a barium study of the upper gastrointestinal tract were included in a double-blinded prospective study. Sonograms were obtained in the right lateral decubitus position to allow gastric fluid to accumulate in the antrum, where it was quantified by measuring the maximal cross-sectional area of antral fluid in square centimeters. Sonograms revealed no fluid or a small amount (less than 5 cm2) in 87 (61%) of the patients and a large amount of fluid (greater than or equal to 5 cm2) in 56 patients (39%). Barium examinations showed a duodenal ulcer in 26 (46%) of the 56 patients with sonographic evidence of a large amount of gastric fluid compared with 10 patients (11%) in the group with little or no fluid on sonography (p = .001). Sonographic evidence of a large amount of fluid was found in all five patients who had gastric-outlet obstruction on barium examination (p = .02). The detection of a large amount of fluid in the stomach on sonography appears to be a feature of duodenal ulcer disease and gastric-outlet obstruction.
我们将143例空腹患者超声检查所确定的胃液量，与十二指肠溃疡疾病及钡餐检查所见胃出口梗阻情况进行了相关性分析。连续入选的因上消化道钡餐检查而转诊的患者纳入一项双盲前瞻性研究。超声检查在右侧卧位进行，以使胃液积聚在胃窦部，通过测量胃窦部液体的最大横截面积（平方厘米）对其进行定量。超声检查显示，87例（61%）患者无液体或少量液体（小于5平方厘米），56例（39%）患者有大量液体（大于或等于5平方厘米）。钡餐检查显示，56例超声检查有大量胃液证据的患者中，26例（46%）有十二指肠溃疡，而超声检查显示少量或无液体的患者组中有10例（11%）有十二指肠溃疡（p = 0.001）。在钡餐检查有胃出口梗阻的所有5例患者中均发现超声检查有大量液体的证据（p = 0.02）。超声检查发现胃内有大量液体似乎是十二指肠溃疡疾病和胃出口梗阻的一个特征。
