Abstract:Objective To investigate the safety and effectiveness of zebra guide wire conversion technique for jejunal nutrition tube implantation under standard gastroscope.Methods 80 patients with spiral nasointestinal tube placed under gastroscope from January 2017 to December 2021 were selected and randomly divided into experimental group and control group, 40 patients in each group. The experimental group used standard gastroscope to place zebra guide wire into the distal duodenum, keep the guide wire position relatively fixed, and replace zebra guide wire into the nasal cavity with disposable catheter after exiting the endoscope instead of inserting guide wire under nasal endoscopy. In the control group, spiral nasointestinal tube was inserted by forceps under standard gastroscope.Results The experimental group under the standard gastroscope was shorter than that of the control group, and there was a statistically significant difference in the operation time between the two groups (P < 0.05); The incidence of nasopharynx discomfort, abdominal pain and abdominal distension in the experimental group was significantly lower than that in the control group, the difference between the two groups was statistically significant (P < 0.05); There were no significant difference in the success rate of one-time catheterization, incidence of aspiration and guide wire displacement (P > 0.05).Conclusion The method of replacing zebra guide wire to nasal cavity with zebra guide wire conversion technology instead of traditional endoscopic clamping method has the advantages of simple operation and few complications, and is safe and effective, which provides technical support for the majority of grass-roots hospitals, and thus provides a new idea for the placement of nutrient tube in digestive endoscopy.
