- Meandering main pancreatic duct (MMPD)
Meandering main pancreatic duct 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.

Epidemiology
Their exact incidence is not known.
Radiographic features
These ductal variants are found on ERCP and MRCP studies.
Clinical significance
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.
