目的探讨分析窄带成像系统在早期胃癌中的应用效果。方法回顾分析2011年1月至12月有上消化道症状的患者4056例胃镜检查临床资料。结果 118例中经病理诊断进展期胃癌99例,早期胃癌2例,慢性胃炎10例;二组使用具有NBI系统及放大功能奥林帕斯GIF-H260Z电子胃镜检查,镜下可疑151例胃癌中经病理诊断进展期胃癌127例,早期胃癌中有24例。以上26例早期胃癌经病理诊断后,黏膜内癌8例、腺癌5例、印戒细胞癌4例、原位癌5例、中重度不典型增生伴癌变6例,同一病灶中可有2种以上癌组织出现。结论早期胃癌中发病年龄与型别有一定关系,年龄越轻,凹陷型越多;随着年龄的增长,则隆起型亦逐渐增多。
Objective To investigate the application of narrowband imaging system in early gastric cancer. Methods The clinical data of 4056 gastroscopy patients with upper gastrointestinal symptoms from January to December in 2011 were analyzed retrospectively. Results Among the 118 cases, 99 cases were diagnosed as advanced gastric cancer by pathological examination, 2 cases were early gastric cancer and 10 cases were chronic gastritis. In the two groups, the gastroscopy was performed using Olympus GIF-H260Z with NBI system and magnification function. Pathological diagnosis of advanced gastric cancer in 127 cases, early gastric cancer in 24 cases. More than 26 cases of early gastric cancer pathological diagnosis, mucosal carcinoma in 8 cases, adenocarcinoma in 5 cases, signet ring cell carcinoma in 4 cases, carcinoma in situ in 5 cases, moderate to severe atypical hyperplasia with cancer in 6 cases, the same lesion may have 2 More cancer types appear. Conclusion The incidence of gastric cancer in early age and type have a certain relationship, the younger, the more depressed; with age, the rise also gradually increased.
