This study is to analyze gastric emptying (GE) of 99mTc tagged solid meals in 43 gastric ulcer (GU), 16 duodenal ulcer (DU) patients, and 15 normal subjects. Diagnosis of active ulcers had been made through high gastrointestinal endoscopy. The patients with GU were divided into three groups according to Johnson's classification. Gastric contents were measured at 15 minute intervals over a period of 150 minutes, with the person standing in front of a gamma-counter. The GE curve was obtained from the mean percentile of radioactivity of all the groups measured at 15 minute intervals. Results were submitted to statistical analysis. Significant delay in GE in DU patients compared to normals, type II and Type III group. However, GE of type I GU was not statistically different from the DU group nor of types II and III GU, occupying an intermediate e position.
本研究旨在分析43例胃溃疡（GU）患者、16例十二指肠溃疡（DU）患者及15名正常受试者中99mTc标记固体餐的胃排空（GE）情况。通过上消化道内镜检查确诊活动性溃疡。GU患者根据约翰逊分类法分为三组。让受试者站在γ计数器前，每隔15分钟测量一次胃内容物，共测量150分钟。GE曲线由每隔15分钟测量的所有组放射性的平均百分位数得出。结果进行统计学分析。与正常组、II型和III型GU组相比，DU患者的GE显著延迟。然而，I型GU的GE与DU组以及II型和III型GU相比无统计学差异，处于中间位置。
