Abstract

We report here on two cases of fractured nitinol stents in the esophagus. In case 1, the correctly inserted stent broke spontaneously shortly after insertion. In a second case, a nitinol stent broke after laser application due to tumor ingrowth with massive bleeding. In both cases, a second stent was implanted in order to reestablish food passage. The fracture of the stent in case 1 seemed to be caused by defective material, whilst in case 2 the stent broke because of thermal overstrain during laser application. The use of electrocoagulation or laser in the stent area should therefore be avoided; argon plasma coagulation may offer an effective alternative in treating tumor ingrowth. As there was a risk from piercing broken filaments with the second stent, covering a fracture using stents with tight walls or plastic tubes seems to be a more effective approach than the inserting an uncovered stent type.
