A Study on Incidence of Accessory Pancreatic Duct and its Clinical Importance
N. VINAY KUMAR and S. LOKANADHAM
ABSTRACT
Background: Erosion of the ductal lumen due to prolonged stagnation of pancreatic juice in the pancreatic ductal system leading to acute pancreatitis
Objective: To study the incidence of accessory pancreatic duct and its clinical importance
Materials and Methods: Fifty formalin fixed cadavers (41 males and 9 females; age range 35–60) from the departments of Anatomy, J. J. M. Medical College, Davengere, Karnataka & Chennai Medical College, Trichy, Tamilnadu, were utilized to study the incidence of accessory pancreatic duct by the dissection method. Pancreas was removed along with duodenum and dissected on its posterior surface to expose the main and accessory pancreatic ducts.
Results: Regarding the types of accessory pancreatic duct, 26 (52%) out of 50 specimens belonged to the long type, 12 (24%) to the short type and 9 (18%) to the ansa pancreatica type. The embryonic type of the duct system was present in three (6%) specimens. The patency of the accessory pancreatic duct, which included patency of the long type, short type and ansa pancreatica type, showed that the accessory duct was patent in 29 (58%) out of 50 specimens. In 18 specimens (36%), the patency of the duct was absent. In three specimens (6%), the embryonic type of the duct system was present.
Conclusion: The accessory pancreatic duct pattern helps in understanding the clinical correlation between pancreatico biliary pathology and associated clinical complications.
