Meandering main pancreatic duct
Citation, DOI and article data
Meandering main pancreatic duct (MMPD) denotes a main pancreatic duct that drains normally into the major papilla but performs a hairpin turn (reverse Z-type) or loop (loop-type) in the pancreatic head, in contradistinction to the smooth curvature seen in most cases.
Significantly increased incidence of meandering pancreatic duct has been reported in patients with idiopathic recurrent acute pancreatitis (40%) compared with the general population (2.2%) 1.
