经鼻胃镜放置肠梗阻导管治疗粘连性小肠梗阻的临床应用

我们将鼻胃镜经鼻插入28例粘连性小肠梗阻的患者十二指肠降段,经活检孔引入亲水性超滑导丝至空肠,退出鼻胃镜,将肠梗阻导管沿导丝送入空肠上段,充盈前气囊后,观察患者治疗前后症状有无缓解、腹围缩小情况及24 h引流量等指标。结果 显示28例患者均1次置管成功,成功率100%。置管时间为10～35 min,留管时间为3～18 d。术中均无并发症发生。患者临床症状均有不同程度改善;24 h引流量480～1 550 mL,平均885 mL;置管24 h后患者腹围（79.1%±20.3%）显著小于置管前（100%,P〈0.05）。可见经鼻胃镜放置肠梗阻导管简便、易行,治疗粘连性小肠梗阻疗效确切,应作为治疗粘连性小肠梗阻的首选方法。

Clinical application of transnasal gastroscope guided ileus tube placement in the treatment of adhesive small intestinal obstruction

For 28 cases of adhesive small intestinal obstruction,we put transnasal gastroscope to the descendant duodenum and put the guide wire in the jejunum via biopsy bore,then retreated transnasal gastroscope,and put the ileus tube to superior segemnet of jejunum via guide wire.Aftet front balloon was filled,symptom relief or not,condition of abdomen circumference dimudition and draining flow within 24 hours were observee beford and after treatment.Twenty-eight cases were set successfully,achievement ratio was 10...
