Applications of Rapid Exchange Method in Transnasal Intestinal Obstruction Catheterization

Purpose To evaluate the application value of rapid exchange method in transnasal intestinal obstruction catheterization.Materials and Methods Fifty-eight patients with adhesive intestinal obstruction underwent transnasal catheterization under X-ray fluoroscopy,of which 31 cases were treated with rapid exchange catheterization method(group A) and the other 27 cases with traditional catheterization method(group B),success rate,operation time and complications were compared between the two groups.Results Catheterization success rate of group A and group B were 96.77%(30/31) and 77.78%(21/27) respectively,which was significantly higher in group A than in group B(χ 2 =4.907,P0.05);operation time of group A and group B were(28.2±12.3) min and(25.4±15.7) min respectively,and the difference between them was not statistically significant(t=1.219,P0.05);no operation associated injury occurred in group A and only one case in group B(3.70%) resulted in bilateral nasal edema with a small amount of bleeding because the operating time was too long,complication rate between the two groups was also not statistically significant(P0.05).Conclusion Rapid exchange method can improve the success rate of transnasal intestinal obstruction catheterization,but the operation time and complications are comparative to those of the conventional method.
