Variaciones anatómicas del conducto cístico

Abstract

In addition to the risks inherent to every major surgery, surgical interventions of the hepatobiliary zone are associated to structural complexity and the presence of anomalies in that zone. In this work on the description of the anatomic variations of the cystic duct, 50 corpses of adult persons (Cadaveric Material), as well 50 Retrograde Endoscopic Colecystopancreatographies of adult (Radiologic Material) were studied. Based on the following characteristics: external distal diameter, length and number of ducts, form, place and level of hepatocystic union, the following results were obtained: Cadaveric Material: external distal diameter, 3 to 4 mm (56%); the presence of one single duct was observed (92%); maximum length, 13 to 18 mm (26%); the angular union (72%); the place of hepatocystic implantation in the right face of the Common Hepatic Duct (84%) and high level (90%). Radiologic Material: external distal diameter, 3 to 4 mm; the presence of the single duct was observed (100%); maximum length 6 to 12 mm (36%); the angular union (68%); the place of hepatocystic implantation in the right face of the Common Hepatic Duct (76%) and high level (84%). With such results, it is recommended that surgeons should have ample knowledge of the MedULA, Revista de Facultad de Medicina, Universidad de Los Andes. Vol. 7 No 1-4. 1998. Merida. Venezuela. 13 anatomy of the hepatobiliar zone and sufficient practical experience, in order to avoid and prevent possible pre and postoperatory complications, thus resulting in benefits for patients and surgeons.
