国内外消化系疾病的研究,在相当长的一段时间内,进展比较缓慢。但最近10年,由于各种基础学科的发展,如纤维光学、免疫学、生物化学及同位素等应用于临床,使消化系疾病的诊断有了新的进展。现从4个方面介绍如下。 (一)纤维内窥镜检查用于消化道的内窥镜有纤维食道镜、纤维胃镜、纤维十二指肠镜、纤维十二指肠子母镜、纤维胆道镜、纤维小肠镜、纤维结肠镜及纤维腹腔镜等。纤维胃镜结合活检及擦刷细胞学检查,对胃癌诊断的准确率在95～99%之间,使胃癌得到早期诊断,5年生存率大大提高。虽然多次活检可增加诊断的准确性,但仔细选择活检的部位更加重要,应该选择颜色不正常和有结节的地方。有溃疡时应该在溃疡内缘而不是在外缘采取组织,因为外缘常
Research on digestive diseases at home and abroad has progressed slowly for a long period of time. However, the recent 10 years, due to the development of a variety of basic disciplines, such as fiber optics, immunology, biochemistry and isotopes used in clinical, the diagnosis of digestive diseases have made new progress. Now from the four aspects described below. (A) of the endoscopic fiber endoscopy for the digestive tract endoscopic fiber esophagus, fiber endoscopy, fiber duodenoscopy, fiber duodenum mirror, choledochofiberscope, fibroscope, colonoscopy And fiber laparoscopy and so on. Fiber gastroscopy with biopsy and brushing cytology, the accuracy of diagnosis of gastric cancer between 95 ~ 99%, so that early diagnosis of gastric cancer, 5-year survival rate greatly increased. Although multiple biopsies can increase the accuracy of the diagnosis, careful selection of the site of the biopsy is even more important and the areas with abnormal color and nodules should be chosen. Ulcers should be in the ulcer edge rather than take the organization in the outer edge, because the outer edge often
