Abstract
ABSTRACT Introduction Endoscopic retrograde pancreatography (ERP) has traditionally been the standard modality for pancreatic endotherapy. However, in certain situations, failure of retrograde ductal access may warrant an alternative modality of drainage. This can occur in various settings like difficult and/or surgically altered anatomy or duodenal obstruction. Endoscopic ultrasound-guided pancreatic duct drainage (EUS-PDD) is a relatively newer addition to the armamentarium for endoscopic access to the PD. Areas covered This comprehensive state-of-art review aims to give an overview of the indications, technical details, different approaches, and outcomes of EUS-PDD, with the latest evidence available in scientific literature. Expert opinion Akin to its biliary drainage counterpart, EUS-PDD enables an EUS-assisted-ERP using rendezvous technique or EUS-guided drainage through transmural stenting. The technique has evolved over the ensuing years with multitude of accessories, approaches, and devices to optimize the outcomes. However, the technical success and adverse events rates need to be further improved. Additionally, it has a steep learning curve with requirements of advanced technical skill and optimum infrastructure back-up. Meticulous patient selection, precise knowledge of ductal anatomy, appropriate approach, and carefully chosen accessories can improve its clinical outcomes.
