EUS-guided pancreatic ductal intervention: A comprehensive literature review.

EUS has opened a new frontier in endoscopic techniques for accessing pancreatic ducts in patients with failed ERCP. The major indications of EUS-guided pancreatic duct intervention (EUS-PDI) are main pancreatic duct (MPD) strictures due to chronic pancreatitis or strictures of pancreaticojejunal or pancreaticogastric anastomosis after Whipple resection, which lead to recurrent acute pancreatitis. EUS-guided pancreaticogastro or duodenostomy offers an alternative to surgery when transpapillary drainage fails or is not possible. We provide an expert commentary and a brief overview on this relatively novel technique utilizing EUS-PDI creation in patients with impaired drainage of the MPD who have failed other conventional endoscopic techniques for MPD drainage and either are poor surgical candidates or are reluctant to undergo surgery.
