Anatomical features of bile ducts in a sample of Colombian corpses

espanolIntroduccion. En comparacion con otros paises, los estudios sobre caracteristicas anatomicas de vias biliares en poblacion colombiana son escasos. Objetivo. Analizar las caracteristicas anatomicas de las vias biliares en una muestra de 60 tractos gastrointestinales de poblacion colombiana. Materiales y metodos. Se realizo un estudio descriptivo analitico transversal donde se emplearon y disecaron las vias biliares de 60 tractos gastrointestinales humanos. Resultados. Segun la clasificacion de Blumgart de las variaciones anatomicas del tracto biliar, se encontraron las siguientes variaciones: Tipo A (78.3%), Tipo B (5%), Tipo C2 (3.3%), Tipo D2 (1.7%), Tipo E1 (1.7%), Tipo E2 (8.3%) y Tipo F (1.7%). En cuanto a las dimensiones promedio de las vias biliares extrahepaticas, se encontraron los siguientes diametros y longitudes: conducto hepatico derecho, 3.62mm y 10.64mm; conducto hepatico izquierdo, 3.66mm y 10.74mm; conducto hepatico comun, 4.97mm y 25.59mm, y conducto coledoco, 4.90mm y 39.58mm. En general, las caracteristicas anatomicas observadas en la mayoria de la muestra fueron similares a las reportadas en la literatura. Conclusiones. En el 78.3% de los casos se observaron caracteristicas anatomicas usuales, mientras que las variantes anatomicas estuvieron presentes en el 21.7%. La longitud y el diametro de las vias biliares estan dentro del promedio reportado en la literatura. EnglishIntroduction: 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.
