原发性小肠肿瘤临床罕见,尸检也很少发现。国外文献累计已超过5000例,国内迄今无精确统计,为了解我国原发性小肠肿瘤发病情况,临床及病理特点,作者收集1938～1985年国内620篇资料,共原发性小肠肿瘤4459例。近年报道较多,仅1983～1985年报告就达1800余例,占总数40.4％。现将其中资料比较完整的2610例进行统计分析。国内2610例原发性小肠肿瘤中良性瘤714例,占27.4％;恶性瘤1896例,占72.6％。714例良性肿瘤的发生部位:十二指肠110例(15.4％),空肠311例(43.6％),回肠293例(41％)。1896例恶性肿瘤的发生部位:十二指肠717例(37.8％),空肠483例(25.5％),回肠696例(36.7％)。发病顺序以良性瘤而言,空、回肠较多,十二指肠较少。恶性瘤则十二指肠、回肠较多,空肠较少。各部位
Primary small bowel tumors are rare clinically and autopsy is rarely found. Over 5,000 cases of foreign literature have accumulated so far. There are no accurate statistics so far. To understand the incidence and clinical and pathological features of primary small intestinal neoplasms in China, the author collected 620 domestic data from 1938 to 1985, which included 4459 cases of primary small intestinal tumors. In recent years, there have been many reports. Only 1983-1985 reports reached more than 1,800 cases, accounting for 40.4% of the total. The 2610 cases with relatively complete data are statistically analyzed. Of the 2610 primary small intestinal tumors in China, 714 were benign tumors, accounting for 27.4%; 1896 were malignant tumors, accounting for 72.6%. Of the 714 benign tumors, 110 were duodenum (15.4%), 311 were jejunum (43.6%), and 293 were ileum (41%). 1896 cases of malignant tumors occurred in 717 cases (37.8%) of duodenum, 483 cases (25.5%) of jejunum, and 696 cases (36.7%) of ileum. In the case of benign tumors, there were more empty and ileal tumors and fewer duodenums. The malignant tumor has more duodenum and ileum and fewer jejunum. All parts
