快速交换法在经鼻型肠梗阻导管置入术中的应用

Applications of Rapid Exchange Method in Transnasal Intestinal Obstruction Catheterization

目的探讨快速交换法在经鼻型肠梗阻导管置入术中的应用价值。资料与方法58例粘连性小肠梗阻患者行X线透视下经鼻型肠梗阻导管置入术,其中31例采用快速交换法置管(A组),27例采用传统方法置管(B组),比较两组置管成功率、操作时间和并发症情况。结果 A组和B组置管成功率分别为96.77%(30/31)、77.78%(21/27),A组置管成功率显著高于B组(χ2=4.907,P<0.05);A组和B组操作时间分别为(28.2±12.3)min、(25.4±15.7)min,差异无统计学意义(t=1.219,P>0.05);A组无一例发生与操作相关的损伤性并发症,B组仅1例(3.70%)因操作时间过长导致双侧鼻黏膜水肿伴少量出血,两组并发症发生率差异无统计学意义(P>0.05)。结论快速交换法可以提高经鼻型肠梗阻导管置入术的成功率,操作时间及并发症发生率与传统置管方法相当。

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 （x2=4.907, P〈0.05）; operation time of group A and group B were （28.2±12.3） min and （25.4±15.7） lain respectively, and the difference between them was not statistically significant （t=1.219, P〉0.05）; 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 （P〉0.05）. 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.
