Obstructing pseudocyst of the duct of Santorini in pancreas divisum.
Pancreas divisum is a pancreatic duct anomaly that occurs due to failure of fusion of the dorsal and ventral ducts. While recognition of this anomaly is increasing due to more aggressive endoscopic retrograde cholangiopancreatography, its significance remains unclear. A patient with chronic pancreatitis and a history of alcohol abuse was noted to have pancreas divisum. At surgical exploration, intraoperative pancreatography revealed an obstructing pseudocyst of the duct of Santorini. Extended sphincteroplasty and cystduodenostomy as well as Roux-en-Y pancreatojejunostomy were necessary to insure adequate accessory duct drainage. Surgical therapy of pancreas divisum in chronic pancreatitis should be designed to correct existing pancreatic duct obstruction.
