本文是一个有计划的回顾性研究。作者等对265例(1974～1976年)胃溃疡病人进行纤维胃镜检查,并提出四个问题:(1)胃溃疡通过胃镜发现恶性的比例有多少?(2)那些特点临床上高度提示可疑恶性?(3)在鉴别良性与恶性时,钡剂造影、内窥镜检查、活检与细胞学检查(细胞刷)的相对优越性是什么?(4)对胃溃疡的侵入性检查发现浅表性癌肿的机会有多少? 方法:1974～1976年英国Bristol皇家医院胃镜检查共2.265人,根据胃镜发现大于2mm直径的胃粘膜断缺或3个月内钡餐检查发现的溃疡为诊断胃溃疡的依据。有多发性溃疡者,以最大者为代表。良性与恶性之区别,尽量以显微镜诊断为肯定依据。X线检查以常规方法为主,部分病人用双重对比造影。胃镜检查均由
This article is a planned retrospective study. The author et al. performed fiberoptic gastroscopy on 265 patients with gastric ulcers from 1974 to 1976 and asked four questions: (1) How many proportions of gastric ulcers have been found to be malignant by gastroscopy? (2) Those features are clinically highly suggestive of suspicious malignancy. (3) What are the relative advantages of barium angiography, endoscopy, biopsy, and cytology (cell brush) in differentiating between benign and malignant? (4) Superficiality of invasive examination of gastric ulcer What are the chances of cancer? Method: From 1974 to 1976, a total of 2.265 gastroscope examinations were performed at the Bristol Royal Infirmary in England. Gastric ulcers larger than 2 mm in diameter were found to be the basis for diagnosing gastric ulcers. . There are multiple ulcers, represented by the largest. The difference between benign and malignant, as far as possible to use microscopy as a positive basis. X-ray examination is based on conventional methods, and some patients use double contrast imaging. Gastroscopy is performed by
