Pancreatic duct occlusion after endoscopic ultrasound-guided transmural pancreatic duct drainage: a pitfall and its rescue technique

Endoscopic ultrasound-guided pancreatic duct drainage (EUS-PDD) is a procedure to access the pancreatic duct in cases of failed endoscopic retrograde cholangiopancreatography (ERCP) [1] [2]. In patients with surgically altered anatomy, transmural drainage is the preferred technique [3]. A single-pigtail plastic stent designed for EUS-PDD has been developed with favorable outcomes [4] ([Fig. 1]).
