为了更好地评价体表胃电图在胃癌诊断中的临床应用价值,我们对经内镜及组织病理学证实的106例胃癌和胃溃疡患者,采用双盲法进行了胃电图检查的对比研究。材料和方法一、病例选择 (一)病例为1988年8月至1989年7月在我院内镜室检查,经病理证实的胃癌和胃溃疡患者。 (二)每例常规作组织活检,取材不少于4块,细胞涂片不少于2张,部分病例加作细胞刷检查。 (三)晚期胃癌、恶病质、衰竭、大出血、穿孔等并发症,急诊手术者不纳入本研究。二、防止偏差因素措施 (一)胃电图检查,仪器为SWT-2型双导胃肠电图仪,仪器及检查医师专人固定。
In order to better evaluate the clinical application value of body surface electrogastrogram in the diagnosis of gastric cancer, we compared the results of electrogastrogram with double-blind method in 106 patients with gastric and gastric ulcers confirmed by endoscopy and histopathology. the study. Materials and Methods 1. Case Selection (A) The cases were from the endoscopic examination in our hospital from August 1988 to July 1989, and were confirmed by pathology in patients with gastric cancer and gastric ulcer. (b) Routine biopsy was performed for each case, with no less than 4 samples taken and no less than 2 cell smears. Some cases were also examined with cytobrushes. (3) Complications such as advanced gastric cancer, cachexia, failure, major bleeding, and perforation, and emergency surgery patients are not included in this study. Second, to prevent deviations measures (A) of the electrogastrogram, the instrument for the SWT-2 type double-guided gastroenterograph, instruments and inspection specialists fixed.
