Abstract

BACKGROUND

When self-expanding metal stents are used in the palliative treatment of malignant stenoses complications can occur and require the endoscopic extraction of the stent.

METHODS

Three Gianturco-Z stents and two EsophaCoil stents had to be extracted because of migration (4 patients) and strangulation of healthy esophageal tissue between the coil loops during EsophaCoil stent release (1 patient). Because of the strong expansion force of the Gianturco-Z stent, the plastic sheath of a polypectomy snare was replaced by the steel sheath of a basket used for mechanical lithotripsy of bile duct stones. The sufficient resistance of the steel sheath allowed the stents to be compressed. The EsophaCoil stents were gradually retracted with a polypectomy snare over a plastic tube.

RESULTS

All stents could be extracted successfully. There were no severe complications related to extraction.

CONCLUSION

By means of the endoscopic extraction techniques described above, it is possible to safely remove self-expanding esophageal stents.

摘要

背景

当自膨式金属支架用于恶性狭窄的姑息治疗时，可能会出现并发症，需要通过内镜取出支架。

方法

由于支架移位（4例患者）以及在释放EsophaCoil支架期间线圈环之间的健康食管组织受压（1例患者），不得不取出3个Gianturco-Z支架和2个EsophaCoil支架。由于Gianturco-Z支架的扩张力很强，息肉切除圈套器的塑料鞘被用于胆管结石机械碎石术的篮子的钢鞘所取代。钢鞘的足够阻力使支架能够被压缩。用息肉切除圈套器通过一根塑料管逐渐收回EsophaCoil支架。
