改良线结牵引在经鼻肠梗阻导管困难型置管中的初步应用（附12例报告）

Preliminary application of modified line junction traction in difficult catheterization in nasal intestinal obstruction (12 cases)

摘要:

目的 初步探讨改良线结牵引在经鼻肠梗阻导管困难型置管中的有效性和安全性。方法 回顾性分析2019年1月—2021年12月该院12例经鼻肠梗阻导管置管困难病例的临床资料，患者均在常规胃镜直视下置管失败后使用改良线结牵引。结果 12例困难置管病例使用胃镜直视下改良线结牵引法均一次性置管成功，平均置管时间（18.2±6.1）min。结论 改良线结牵引在经鼻肠梗阻导管困难型置管中安全、有效，特别是对十二指肠球降部转折急、角度小的病例，能提高置管成功率。

Abstract:

Objective The effectiveness and safety of improved line junction traction in 12 cases with difficult nasal intestinal obstruction were discussed.Methods Review 12 cases with difficult catheterization for nasal intestinal obstruction from January 2019 to December 2021 and traction with modified line junction after direct catheterization failure with conventional gastroscopy.Results In 12 cases, mean placement time (18.2 ± 6.1) min.Conclusion The improved line junction traction is safe and effective in the difficult catheterization of nasal obstruction, especially in the case of duodenal drop.
