X线透视下经鼻十二指肠营养管的置入及临床应用

目的探讨X线透视下十二指肠营养管的置入及其临床应用价值。方法从2003年6月3日至2007年8月17日,59例患者在X线透视下行经鼻十二指肠营养管置入,置管成功后营养管末端位于十二指肠空肠连接部。结果59例患者中首次成功放置空肠营养管57例,成功率96.6%,2例患者因明显胃扩张首次置管失败后在充分胃肠减压后置管成功。置管时间为3.9～68.6 min,平均17.8 min。置管中及置管后未发生严重并发症。结论X线透视下经鼻十二指肠营养管置入是一种安全、经济、有效的肠内营养途径,因而具有广泛的临床应用价值。

Clinical application of transnasal feeding tube placement under fluoroscopic guidance

Objective To evaluate the feasibility and effectiveness of duodenal feeding tube placement under fluoroscopic guidance and its clinical application.Methods The transnasal duodenal nutriment tubes placement under fluoroscopic guidance were performed in 59 patients from June 3th,2003 to August 17th,2007.The successful placement of the feeding tube was defined as that of the tube tip was fixed at or distal to the duodenojejunal junction.Results 57 out of 59 patients were successfully managed by feeding tube placement,with primary successful rate of 96.6%(57/59).The remaining two failures were due to overdistention of the stomach and were further managed after gastrointestinal decompression thoroughly.The mean fluoroscopy time of the procedure was 17.8 minutes with no severe immediate or delayed complications.Conclusion The transnasal duodenal nutrient feeding tube placement under fluoroscopic guidance is a safe,economic,and effective management for enteral nutrition,providing extensive clinical utilization.
