Summary
Awareness of variations in the anatomy of extrahepatic bile ducts may be important in preventing iatrogenic injury to the duct system during cholecystectomy. Their delineation, before or during surgery is therefore considered mandatory in this surgical unit, and a policy of always performing a per-operative cholangiogram has allowed us to evaluate the duct system in a retrospective review of 2080 cases. Twelve surgically significant anatomical variations were found, consisting of absent cystic duct (three cases), abnormal termination of cystic duct (two into the right hepatic duct, and one into the left hepatic duct), one case of double cystic duct, and five cases of significant accessory bile ducts.
Résumé
La connaissance des variations anatomiques des voies biliaires extra-hépatiques est un élément important pour la prévention des plaies biliaires iatrogènes au cours de la cholecystectomie. Leur recherche systématique préopératoire ou peropératoire est donc exigée dans notre pratique chirurgicale et le recours systématique à une cholangiographie per-opératoire a permis d'étudier les variations des canaux biliaires dans une étude rétrospective de 2080 cas. Douze types de variations canalaires avec incidence chirurgicale ont été découverts : l'absence de conduit cystique (trois cas), la terminaison anormale du conduit cystique (deux fois dans le canal hépatique droit, une fois dans le canal hépatique gauche), un cas de dédoublement du conduit cystique et cinq cas de canaux biliaires accessoires.
