Variedades Anatómicas del Árbol Biliar: Implicancia Quirúrgica

Abstract

The anatomy of the biliary tract have frequent variations. Normal anatomy is described in about half of cases. The varieties of the bile ducts should be known by physicians and hepatobiliary surgeons specializing in diagnostic imaging, in order to optimize performance in their respective areas. To this end 690 cholangiographies (538 intra-operative, 90 resonances, and 62 trans- catheter bile) were prospectively studied. We used the classification of Blumgart and the results were as follows: type A: 284 (41.16%), B: 178 (25.80%). C1: 110 (15.94%), C2: 38 (5.51%)., D1: 8 (1.16%), D2: 23 (3.33%), E1: 18 (2.61%), E2: 27 (3.91%), F: 4 (0.58%). As conclusion, it is important to note that: a) intra-operative cholangiography should be systematic, on the one hand, to exclude cholelithiasis and, on the other hand, to detect and predict anatomical changes before resective surgery and b) cholangioresonance is an ideal preoperative study in potential living donors of organs.
