1 对象和方法 1.1 对象 1991年7月-1992年3月我院门诊及病房经内镜证实十二指肠溃疡(DU)活动期的患者共74例:其中男57例,女17例;年龄17-68岁,平均39.57±11.74岁。其中复发性73例,初发1例;合并瘢痕球15例(20%),流出道轻度受阻17例,中度受阻32例,重度受阻13例。 1.2 方法经内镜确诊为DU活动期患者,常规做五肽胃泌素试验检测胃酸,用胃磁图仪测定其胃排空时间。测定方法见已发表文献。以33名正常人作胃排空时间测定对照,研究DU活动期患者的内镜形态学改变及胃酸与胃排空的相关关系。
1 Subjects and methods 1.1 Object July 1991 - March 1992 in our hospital outpatient and ward endoscopic confirmed duodenal ulcer (DU) active phase of a total of 74 patients: 57 males and 17 females; age 17-68 years old, with an average of 39.57 ± 11.74 years old. Among them, 73 were recurrent and 1 was initially diagnosed. There were 15 cases (20%) with scarring, 17 cases with mild outflow tract obstruction, 32 cases with moderate obstruction and 13 cases with severe obstruction. 1.2 Methods Endoscopic diagnosis of DU active stage patients, conventional pentagastrin test gastric acid, gastrograph was used to determine the gastric emptying time. Determination methods see the published literature. Twenty-three normal subjects were tested for gastric emptying time to study the changes of endoscopic morphology and the relationship between gastric acid and gastric emptying in patients with active DU.
