Successful recanalization of complete bile duct obstruction using piercing technique under cholangioscopic guidance

“…Cholangioscopy-assisted guidewire placement and a piercing technique have been reported for postoperative biliary strictures or obstructions 1 2 3 4 5 . The combination of both as shown here is a useful alternative for difficult cases.…”

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

“…However, the hyperplasia was too stiff. Finally, a "piercing technique" using the stiff back end of the guidewire [5] was performed, which allowed the guidewire to smoothly advance the stricture (▶ Fig. 4, ▶ Video 1).…”

Piercing technique for recanalization of pancreaticojejunal obstruction through the endoscopic ultrasound-guided pancreatic duct drainage route

“…5). Puncture with the stiff back end of a guidewire has been previously reported as a piercing technique [2,3]. In the EUS-PD procedure, recanalization of the complete anastomotic obstruction is key to a successful treatment.…”
