This study details improvements in the intubation of a long intestinal decompression tube by use of a new flexible tip guide wire and a new intestinal decompression tube. The intubation route of the endoscope was changed from the oral to the nasal cavity. Although the guide wire formerly used (TGBD-65-345) could be inserted into the descending part of the duodenum by passing it through the biopsy channel of the endoscope, with this new method, the guide wire (TGBD-65-450) could be inserted into the upper jejunum. The endoscope could also be left in the stomach, when this method was used. The long tube was introduced along this guide wire into the upper jejunum. As a result of these improvements, the intubation rate for long intestinal decompression tubes was significantly more rapid and the time reduced. Intubation rate to the jejunum was 96 percent successful, as compared with a former success rate of 75 percent. The intubation time was decreased to 11.3 +/- 5.6 min. to the duodenum and 18.6 +/- 8.6 min. to the upper jejunum. This differs markedly from the former method which required 16.0 +/- 5.3 min. and 39.6 +/- 22.7 min, respectively.
本研究详细介绍了使用新型柔性尖端导丝和新型肠道减压管在插入长肠道减压管方面的改进。内窥镜的插管途径从口腔改为鼻腔。尽管以前使用的导丝（TGBD - 65 - 345）可通过内窥镜的活检通道插入十二指肠降部，但采用这种新方法时，导丝（TGBD - 65 - 450）可插入空肠上段。使用这种方法时，内窥镜也可留在胃内。沿着该导丝将长管引入空肠上段。由于这些改进，长肠道减压管的插管速度明显加快，时间缩短。空肠插管成功率为96%，而以前的成功率为75%。插入十二指肠的时间降至11.3±5.6分钟，插入空肠上段的时间降至18.6±8.6分钟。这与以前的方法明显不同，以前的方法分别需要16.0±5.3分钟和39.6±22.7分钟。
