Core Tip

Core Tip: We present a case in which the guidewire lasso technique was used to remove a fractured esophageal Z-stent. A 74-year-old man developed dysphagia approximately 6 mo after resection for esophageal cancer and a Z stent was inserted. After 13.5 mo, esophagography showed severe stenosis above the proximal stent. One-third of the stent was removed and the fractured stent remained in the proximal esophagus. A suction tube was introduced through the guidewire and then the guidewire was grabbed, acting like a “lasso” on tightening. The fractured stent was successfully removed by slowly pulling back the guidewire, with no fragments of stent wires retained.
