Contribution of the study of the pancreatic duct system in thorouhbred equines

Abstract

It was studied, by dissection, the pancreatic duct system in 30 thoroughbred equines (15 males and 15 females) adults. The results obtained show that the main duct (Wirsung's) proceeds from the union of two roots, the collectors of the right and left lobes and receives, as well as its roots, varied number of affluents, respectively : four (13.3%), six (13.3%), seven (13.3%), one (10.0%), eight (6.7%), nine (6.7%), ten (6.7%), thirteen (6.7%), sixteen (6.7%), two (3.3%), three (3.3%), five (3.3%), eighteen (3.3%) and twenty (3.3%); eight (16.7%), ten (13.3%), eleven (10.0%), thirteen (10.0%), twenty one (10.0%), twelve (6.7%), eighteen (6.7%), four (3.3%), six (3.3%), nine (3.3%), fourteen (3.3%), fifteen (3.3%), twenty (3.3%), twenty three (3.3%) and twenty four (3.3%); sixteen (16.7%), eighteen (10.0%), twenty four (10.0%), fourteen (6.7%), twenty eight (6.7%), thirty one (6.7%), twelve (3.3%), seventeen (3.3%), nineteen (3.3%), twenty (3.3%), twenty one (3.3%), twenty two (3.3%), twenty six (3.3%), thirty (3.3%), thirty two (3.3%), thirty three (3.3%), thirty four (3.3%), thirty seven (3.3%), thirty eight (3.3%), thirty nine (3.3%). A secondary system is composed by the Santorini duct which reaches, almost always, (76.7%) the lesser duodenal papilla and opens, by its central extremity, directly in the Wirsung duct (70.0%), in the duct of the left lobe (13.3%) or in the duct of the right lobe (10.0%). It receives, several afferents in its trajectory , that is: five (16.7%), four (13,3%), eight (10,0%), nine (10.0%), three (6.7%), six (6.7%), seven (6.7%), two (3.3%), eleven (3.3%), twelve (3.3%), fourteen (3.3%), fifteen (3.3%), sixteen (3.3%), nineteen (3.3%) and twenty two (3.3%). Anastomosis were seen communicating diverses collectors of the pancreatic duct system, in a good deal of glands (66.7%)
