Abstract：Objective To investigate the clinical efficacy of a modified technique for transnasal ileus tube insertion and evaluate its feasibility and safety in clinical practice.Methods Clinical data were collected from patients admitted to the Second Affiliated Hospital of Kunming Medical University from August 2022 to December 2024,who underwent the modified intestinal obstruction catheterization procedure in the Interventional Radiology Department.The success rate,efficacy,and postoperative complication rate(2.7%)of the modified method were analyzed.Feasibility was evaluated based on first-attempt success rate and clinical effectiveness rate,while safety was assessed by the incidence of postoperative complications.Patients were categorized into significant efficacy,effective,and ineffective groups according to clinical outcomes.Results Among 113 procedures,108 were successfully performed(success rate:95.6%),with 96 cases achieving clinical effectiveness(84.9%)and 12 cases deemed ineffective(10.6%).Three patients experienced catheter blockage or displacement(2.7%).No severe complications,such as aspiration,asphyxia,gastrointestinal bleeding or intestinal perforation,were observed during hospitalization or follow-up.Conclusion The modified technique for transnasal intestinal obstruction catheterization demonstrates a high success rate,definite therapeutic efficacy for patients with simple small bowel obstruction,and a low incidence of postoperative complications,warranting broader clinical promotion.
