Quijano Blanco, Yobany | 2020
Introduction: In comparison with other countries, studies on the anatomical characteristics of bile ducts in Colombian population are scarce. Objective: To analyze the anatomical features of bile ducts in a sample of 60 gastrointestinal tracts obtained from Colombian cadavers. Materials and methods: A cross-sectional, analytical and descriptive study was conducted. The bile ducts of 60 human digestive tracts were dissected and analyzed. Results: According to the Blumgart’s classification of the biliary tract anatomical variations, the following variations were found: Type A (78.3%), Type B (5%), Type C2 (3.3%), Type D2 (1.7%), Type E1 (1.7%) Type E2 (8.3%), and Type F (1.7%). Regarding the average dimensions of bile ducts outside the liver, the following average lengths and diameters were found: right hepatic duct, 10.64mm and 3.62mm; left hepatic duct, 10.74 mm and 3.66 mm; common hepatic duct, 25.59 mm and 4.97 mm, and common bile duct, 39.58 mm and 4.90 mm. In general, the anatomical features observed in most of the sample were similar to those reported in the literature. Conclusions: Usual anatomical features were present in 78.3% of the cases, while anatomical variations were observed in 21.7%. The length and diameter of the bile ducts studied here is within the average range reported in the literature.
