目的：研究胃癌时胆石症的患病率，希望通过临床流行病积累的资料，部分阐明胆石症发病的某些因素。方法：４７７例经胃镜（及病理）、手术确诊的胃癌患者，在确诊同时进行Ｂ超检查了解有无胆石症。与同一地区健康普查人群进行对照分析。结果：不论男、女患者，按癌的部位分群，多年龄层之间胆石症患病率无显著差异。按年龄组分群，不同部位胃癌间的胆石症患病率亦无明显差异。不论男、女患者，胆石症患病率均随年龄增加面上升，女性尤著（Ｐ＜０．０５）。同年龄组，女性患者恒比男性高（Ｐ＜０．０５）按性别分群与年龄分层。胃癌患者与健康人之间无显著差异。结论：胃癌患者胆石症患病率与健康人无差异。性别与年龄仍然是决定胆石症患病率最重要因素
Objective: To study the prevalence of cholelithiasis in gastric cancer. It is hoped that some of the factors in the pathogenesis of cholelithiasis will be elucidated through the data of clinical epidemiological accumulation. METHODS: A total of 477 patients with gastric cancer diagnosed by gastroscopy (and pathology) and surgery were examined at the same time for B-ultrasound to find out whether there was cholelithiasis. Compare with the health survey population in the same area. Results: There was no significant difference in the prevalence of cholelithiasis between multiple age groups according to the location of cancer in both male and female patients. According to the age group, there was no significant difference in the prevalence of cholelithiasis between different sites of gastric cancer. Regardless of male or female patients, the prevalence of cholelithiasis increased with age, especially in women (P<0.05). In the same age group, the female patients were higher than males (P<0.05) and stratified by sex and age. There was no significant difference between patients with gastric cancer and healthy people. Conclusion: The prevalence of cholelithiasis in patients with gastric cancer is not different from that in healthy individuals. Gender and age are still the most important factors determining the prevalence of cholelithiasis
