Introduction: The accessory pancreatic duct also called as dorsal pancreatic duct or Santorini duct as it is formed from the portion of dorsal bud and was first described by Santorini in 1775. It is the main drainage duct of the dorsal pancreatic bud in the embryo and enters the duodenum at the minor duodenal papilla.
Methods: The study was conducted on 30 pancreas and duodenum enblock obtained from adult cadavers in the Forensic medicine Department of Govt. Medical College, Amritsar. Length and width of accessory pancreatic duct were measured and the results were compared according to the sex and were also analysed statistically. The shape of terminal part of the accessory pancreatic duct has also been discussed with reference to patency of the duct.
Results: Length of accessory pancreatic duct ranged between 2.0-6.2cm with a mean of 3.89+ 0.85cm. Width of accessory pancreatic duct ranged between 1.33-2.01cm with a mean of 1.67+ 0.48cm.The most common terminal shape of accessory pancreatic duct observed was stick type in 63.33% and the least common was saccular type i.e. 3.33%. In decade wise division into group I (<40 yrs) and group II (>40 yrs), length of the accessory pancreatic duct did not show any alteration with age but width was significantly greater in group II as compared with group I in male and in female subjects.
Conclusion: The anatomical aberrations in the duct system of pancreas have clinical importance because they can predispose to various clinical disorders including pancreatitis and carcinogenesis. Aging also results in increase in the diameter of the pancreatic duct. Pancreas divisum is a common anatomical variation, in which the dorsal and ventral pancreatic ducts do not unite leading to inadequate pancreatic juice drainage resulting in dorsal pancreatitis.
