BACKGROUND
With present techniques, transpyloric feeding tube placement is unreliable. This study evaluated a new nasoduodenal tube placed through a gastroscope.
METHODS
A therapeutic gastroscope was advanced into the distal duodenum, and through the 3.7-mm channel this feeding tube was advanced under direct vision into the small bowel. The tube/guidewire combination was then advanced with the concomitant equidistant retraction of the scope until the wire could be grasped at the lips and exchanged to the nose using a nasal transfer tube. The guidewire was removed, and a "Y" connector was then attached to the end of the tube.
RESULTS
Successful tube placement in all 21 patients (14M/7F) required an endoscopy time of 31 +/- 3.3 min and the tubes were utilized for 9.24 +/- 0.94 days. Tube tips were confirmed in the distal duodenum (10) or proximal jejunum (11) by radiographic contrast injection.
CONCLUSION
This new through-the-scope tube can be placed in the distal duodenum quickly, safely, and consistently.
背景
采用目前的技术，经幽门放置喂养管不可靠。本研究评估了一种通过胃镜置入的新型鼻十二指肠管。
方法
将治疗性胃镜推进至十二指肠远端，通过3.7毫米的通道，在直视下将该喂养管推进至小肠。然后推进管/导丝组合，同时等距离回撤胃镜，直到能在唇部抓住导丝，并使用鼻转换管将其换至鼻腔。移除导丝，然后在管的末端连接一个“Y”形连接器。
结果
所有21例患者（14例男性/7例女性）均成功放置了管子，所需的内镜检查时间为31±3.3分钟，管子使用了9.24±0.94天。通过造影剂注射确认管尖端位于十二指肠远端（10例）或空肠近端（11例）。
结论
这种新型的经胃镜管能够快速、安全且持续地放置于十二指肠远端。
