患者男,70岁。2天前出现黑便,解黑色成形大便2次,总量约800g,无呕血、无发热。

提示该患者的血常规结果为:白细胞8.3×109/L,血红蛋白108g/L,血小板104×109/L。肿瘤标志物检查结果为:癌胚抗原(CEA)5.3ng/ml(正常<3.4ng/ml)。腹部B超及胸片未见异常。上腹部CT提示胃壁增厚。该患者出现黑便可能性最大的原因为()。

B.胃癌

C.急性胃黏膜损伤

D.胆道出血

E.门脉高压性胃病

F.系统性红斑狼疮

G.胃泌素瘤

答案

参考答案:B

解析:

2.患者表现为黑便成形大便,无呕血。根据其年龄、既往史及现有资料,目前考虑此次上消化道出血的可能原因为胃溃疡和胃肿瘤。

6.该患者在检查后出现呕血、黑便,并伴有周围循环衰竭表现。考虑有活动性出血,出血量大,应在抗休克治疗后生命体征平稳情况下考虑下一步诊疗计划。

专家点评:此患者为老年男性,既往有胃溃疡病史。近半月来感上腹痛,体重下降,肿瘤标志物升高,其后胃镜检查提示胃体部癌。其后出现上消化道大量出血,为临床急重症,应采取积极措施进行抢救。
