Abstract: Objective To investigate the clinical efficacy of transnasal gastroscopy combined with short-length switching in nasal insertion type ileus tube catheterization. Methods Clinical data of 60 patients meeting the diagnostic criteria for acute simple small intestinal obstruction were included in this study. Patients were randomly divided into endoscopic group (n=30) and fluoroscopic group (n=30). The success rate of catheterization, total operation time, radiation exposure time, catheterization depth, anal spontaneous exhaust time and efficiency were compared between the two groups.Results There were no significant differences in age, sex and operation history between the two groups. There were no significant differences in the success rate of catheterization, catheterization depth and efficiency between the two groups (P＞0.05). The total operation time and radiation exposure time were significantly less in the endoscopic group than those of the fluoroscopic group (P＜0.05). Conclusion Endoscopic-assisted indwelling of nasal intestinal obstruction catheter simplifies the cooperation between doctors and patients, shortens the total operation time and radiation exposure time, and is worthy of clinical promotion.
