Endoscopic transpapillary or transanastomotic pancreatic duct drainage (PD) is the mainstay of drainage in symptomatic pancreatic duct obstruction or leakage. However, transpapillary or transanastomotic PD can be technically difficult due to the tight stricture or surgically altered anatomy (SAA), and endoscopic ultrasound (EUS)-guided PD (EUS-PD) is now increasingly used as an alternative technique. There are two approaches in EUS-PD: EUS-guided rendezvous (EUS-RV) and EUS-guided transmural drainage (EUS-TMD). In cases with normal anatomy, EUS-RV should be the first approach, whereas EUS-TMD can be selected in cases with SAA or duodenal obstruction. In our literature review, technical success and adverse event rates were 78.7% and 21.8%, respectively. The technical success rate of EUS-RV appeared lower than EUS-TMD due to the difficulty in guidewire passage. In future, development of dedicated devices and standardization of EUS-PD procedure are necessary.
