Nonoperative replacement of lost or occluded jejunal feeding catheters proved successful in 8 of 11 patients. This technique is recommended as a nonoperative means of replacing a needle catheter jejunostomy when it is accidentally lost or becomes occluded. Adherence to sterile technique and gentle advancement of the guide wire to avoid injury to the bowel are important. Since the technique depends on an established tract between the skin and the bowel, catheter replacement should not be attempted when the feeding catheter is lost or becomes occluded in the immediate postoperative period. In addition, confirmation of catheter patency and intraluminal position with sterile water-soluble contrast medium is critical to the safe use of this technique.
11例患者中有8例通过非手术方式成功更换了丢失或堵塞的空肠喂养导管。当针导管空肠造口术意外丢失或堵塞时，推荐使用该技术作为更换导管的非手术方法。遵守无菌技术并轻柔推进导丝以避免肠损伤很重要。由于该技术依赖于皮肤与肠之间已形成的通道，因此在术后即刻喂养导管丢失或堵塞时不应尝试更换导管。此外，使用无菌水溶性造影剂确认导管通畅和管腔内位置对于该技术的安全使用至关重要。
