OBJECTIVE: Pancreaticoduodenectomy has been established as the treatment of choice for the management of benign and malignant lesions of the pancreatic head, and pancreaticojejunal or pancreaticogastric anastomosis seems to be the safer choice for the management of the pancreatic duct. However, in certain seldom, but still existing circumstances, pancreatic duct ligation or occlusion with a chemical substance is a valuable and viable alternative. The aim of the current study is to compare these two methods of occlusion of the pancreatic duct regarding the endocrine and exocrine function of the pancreas and its histopathology.
MATERIALS AND METHODS: 18 health mixed breed dog of both sexes were randomized in two groups: group A, in which the pancreatic duct was ligated and group B, in which the pancreatic duct was occluded with prolamine.
RESULTS: None of the animals presented postoperatively steatorrhea and significant body weight changes. Peripancreatic inflammation at sacrifice, inflammatory cell infiltration and edema of the pancreas on the 15th postoperative day and 30th postoperative day were milder after occlusion with prolamine than after ligation. Ligation of pancreatic duct lead to significantly greater hyperamylasemia than prolamine occlusion every day until the 15th. Mild hyperglycemia presented from the first to the fourth day in both groups, which was associated with a significant drop in insulin. Glucagon remained within the normal values at all times during the experiment. None of glucose, insulin and glucagon differed between groups.
CONCLUSION: Prolamine occlusion of the pancreatic duct causes milder hyperamylasemia and less extensive inflammation both macroscopically and microscopically than ligation.
