对53例早期胃癌病人采用内窥镜刚果红试验法(endoscopic Congo red test),测定其胃泌酸区范围的大小,并对照观察了该组早期胃癌的大体形态和组织学所见,从中探讨泌酸区范围与早期胃癌的大体形态、组织学类型以及癌瘤部位之间的关系。方法: 对53例早期胃癌病人在手术前作了胃内窥镜检查,并经纤维胃镜向胃粘膜喷射0.3%刚果红及5%碳酸氢钠溶液使胃粘膜着色。给病人肌注四肽胃泌素(tetragastrin)促使胃酸分泌。从内窥镜中可见,泌酸区的粘膜由于胃酸作用转变为兰黑色,称去色区(discolored area),无胃酸分泌部分颜色不变,称非去色区(nondiscolored area),根据去色区范围大小,把泌酸区分为“大”、“小”、“无”三型。“大”,指胃体部几乎
An endoscopic Congo red test was performed on 53 patients with early gastric cancer to determine the size of the oxyntic acid region. The gross morphology and histological findings of this group of early gastric cancer were observed and compared. The relationship between the range of oxyntic region and the gross morphology, histological type, and the site of cancer in early gastric cancer. Methods: A total of 53 patients with early gastric cancer were examined by gastroscopy before surgery. Gastric mucosa was stained with 0.3% Congo red and 5% sodium bicarbonate solution through gastric endoscopes. Intramuscular injection of tetragastrin promotes gastric acid secretion. It can be seen from the endoscope that the mucous membrane of the oxychrone is converted to blue-black due to the action of gastric acid, called the discolored area, and the color of the part without gastric acid remains unchanged, which is called the nondiscolored area, according to decolorization. The size of the district is divided into three types: “large”, “small”, and “no”. “Large” means that the body of the stomach is almost
