Piercing technique for mucosal hyperplasia at an uncovered part of a partially covered stent after endoscopic ultrasound-guided hepaticogastrostomy

Abstract

Indiana, United States) was inflated inside the partially covered metal stent to allow passage of the guidewire through the center of the stent (a fluoroscopic view, b. diagram).▶ Fig. 4 In a "piercing technique," the stiff back end of a 0.035-inch guidewire (Jagwire; Boston Scientific, Natick, Massachusetts, United States) was used, which enabled the smooth advancement of the guidewire beyond the hyperplasia at the proximal end of the stent (a fluoroscopic view, b diagram).
