胃角不同部位肿瘤的内镜诊断比较分析

A retrospective study of endoscopic diagnosison gastric angle tumors

[目的]认识胃部恶性肿瘤的好发部位,提高胃癌的诊疗水平。[方法]回顾性分析经胃镜检查9 133例胃不同部位病变患者的病历资料,重点对其中864例局限于胃角(胃角切迹范围内2cm)病例的内镜表现进行研究和分析。[结果]9 133例病例中胃癌约占0.83%,胃窦是易发病的部位;良恶性溃疡病变的检出率:胃窦>胃角>胃体>胃底贲门;各部位中恶性肿瘤检出率最高为胃角,864例胃角病例中胃角恶性肿瘤检出率高达6.60%;胃角恶性肿瘤多发于中老年男性患者,男女比例为4.5∶1.0,胃角不同部位恶性肿瘤检出率:胃角体侧>胃角切迹>胃角窦侧。[结论]胃癌好发于中老年男性患者,胃角恶性肿瘤检出率最高,胃角体侧恶性肿瘤检出率更为显著;故胃角是内镜检查的重点观察部位,胃角体侧尤需仔细。

[Objective]To recognize the predilection sites of gastric cancer and to improve the diagnosis of gastric cancer.[Methods]A retrospective analysis of the endoscopic manifestations of 9133 lesions in different site of stomach,including 864 lesions limited in the gastric angle（2 cm within the angle of gastric horn）were studied and analyzed.[Results]In the 9133 lesions,gastric cancer accounted for about 0.83%,the most common position located in the gastric antrum.The incidence of benign and malignant lesions were gastric antrum（A）〉gastric angle（B）〉gastric body（C）〉gastric cardia（D）（A vs B：P〈0.01,A vs C：P〈0.05,A vs D：P〈0.01,B vs C：P〈0.01,B vs D：P〉0.05,C vs D：P〈0.01）.The highest incidence of gastric cancer was found in gastric angle,which was as high as 6.60%in the 864 cases.The gastric angle cancer was more common occurred in old male patients,the male to female ratio of 4.5：1.0.The incidence rate of gastric cancer was gastric angle,body side（A）〉Gastric angle（B）〉gastric angle antrum side（C）（A vs B：P〈0.05,A vs C：P〈0.01,B vs C：P〈0.01）.[Conclusion]The incidence of gastric cancer in middleaged and elderly male patients is the highest,and the incidence rate of gastric angle cancer is predominant.Therefore,the gastric angle is the focus of the endoscopic examination,especially in the body side of gastric angle.
