野战条件下脾下极破裂的最合适的处理方法是()

A.脾修补术

B.脾切除术

C.脾部分切除术

D.脾动脉结扎术

E.非手术治疗

答案

参考答案:B

解析:脾切除术广泛应用于脾破裂、游走脾(异位脾)、脾局部感染或肿瘤、囊肿、肝内型门静脉高压症合并脾功能亢进等引起充血性脾肿大等疾病。脾脏是人体内最大的周围淋巴器官,能够产生多种免疫活性细胞因子,是机体储血、造血、滤血、毁血的主要器官,具有重要的免疫调节、抗感染、抗肿瘤、内分泌及产生备解素及促吞噬肽等作用。基于目前对脾脏功能的了解以及切脾后所导致患者对感染的易感性增加的后果,在条件及疾病允许的情况下,尽量行脾保留手术,已是目前全球外科医师的共识,即"抢救生命第一,保留脾脏第二,年龄越小越优先保脾"。野战条件下脾下极破裂的最合适的处理方法是脾切除术。故答案应选B。
