问题 单项选择题 案例分析题

患者,男,72岁。因进食时误吞鸭骨后吞咽困难和吞咽疼痛6小时,在当地医院就诊,经照X线片发现食管中段有不透光的阴影,由于当地医院条件有限,仅给予抗感染、对症和支持治疗两天,症状无明显缓解,且出现背部及胸骨后疼痛,多次呕吐,呕吐物为唾液样物,其中两次带有少许鲜血,于是转院治疗。

应该继续完善的检查是()

A.重新作X线检查

B.心电图检查

C.血尿常规

D.肝、肾功能检查等

E.以上都对

F.以上都不对

答案

参考答案:E

解析:

重新照X线片检查,观察异物的位置是否与原来的位置相一致,并且判断异物所在的位置与主动脉弓的关系。作好全麻的术前准备,如心电图检查、血常规, 肝、肾功能检查等;异物所在位置很可能在食管与主动脉弓交叉处;完善术前准备后,与胸外科讨论取出食管异物的方案。全麻后,用食管镜进一步观察异物的位置 是否位于主动脉弓区域,以及出血的情况。如果不位于血管区,可以直接取出异物;如果位于主动脉弓,且异物随动脉搏动而动、并伴有搏动性出血,则请胸外科开 胸探查取异物,并及时修复动脉。术后禁食、抗感染、对症、支持治疗。
