目的：探讨泥鳅导丝配合鹅颈套圈成圈技术在抓取腔内管状异物中的可行性及适用范围。方法2009年7月-2013年12月，收治3例经外周静脉置入中心静脉导管（PICC）体内断管患者、1例植入式静脉输液港导管断管患者及2例更换双“J”管患者，均为女性。采用泥鳅导丝配合鹅颈套圈成圈技术（即将导丝和鹅颈套圈分别置于管状物两侧，用鹅颈套圈将泥鳅导丝前端柔软部分套住后即形成一圈型结构）对6例患者进行取管操作。结果应用成圈技术均顺利、安全的取出6例患者体内断管或双“J”管。结论泥鳅导丝配合鹅颈套圈成圈技术是一种有效的、快捷的抓取腔内管状异物的方法，值得掌握和推广。%Objective To investigate the feasibility and application scope of the looping technique by using a gooseneck snare and a loach guide wire in retrieving tubular foreign bodies within the vascular or ureteral duct. Methods During the period from July 2009 to Dec. 2013, six patients with ruptured catheter were admitted to authors’ hospital. All six patients were females. Three patients had internal ruptured peripherally inserted central venous catheter (PICC), one patient had ruptured implantable venous access port catheter and two patients had replacement of double “J” ureteral catheter stent. By using looping technique, i.e. a loach guide wire and a gooseneck snare were separately placed at the two ends of the tubular foreign body, then the gooseneck snare entangled the soft leading end of the loach guide wire to form a annular structure to seize the ruptured tubular catheter and then to pull it out of the body. Results With the help of the looping technique, the internal ruptured catheter or the double “J” ureteral catheter was successfully removed in all the six patients. Conclusion For the retrieval of the tubular foreign bodies within the vascular or ureteral duct, the looping technique by using a gooseneck snare and a loach guide wire is an effective and fast treatment. Therefore, this technique should be recommended in the clinical practice.
