Objective To evaluate the diagnosis and treatment of transcatheter small bowel radiography in intestinal obstruction.Methods From January 2016 to December 2016,150 cases of adhesive small intestine obstruction were divided into small bowel radiography group and control group.The long-term results were collected after 6-month follow-up.Results First aerofluxus time [(72 ± 5) h vs.(109 ±7) h],defecation [(89 ±8)h vs.(139 ± 17)h],extubation [(81 ± 18)h vs.(105 ± 17)h] and first oral intake [(84 ±6)h vs.(109 ±9)h] in catheter group were shorter compared with control group (all P ＜ 0.05).The accuracy of determining obstruction site were superior in catheter group than control group (92％ vs.63％,P ＜ 0.05).Conclusion Endoscopic transnasal ileus tube significantly relieves symptoms in the adhesive intestinal obstruction,the transcatheter small intestinal radiography helps determine the obstruction site.
