ABSTRACT

This concise abstract explores the anatomy of the biliary system, emphasizing normal structure and anatomical variations. The gallbladder, cystic duct, bile ducts, and pancreas collectively contribute to digestive processes. The complex intrahepatic and extrahepatic bile duct network is regulated by the sphincter of Oddi. Normal radiological views, as defined by Couinaud, underscore segmental anatomy. However, developmental variations may challenge accurate representation, potentially leading to surgical complications. Imaging methods such as computed tomography and ultrasound may fall short in revealing these variations, while endoscopic retrograde cholangiopancreatography offers precision at the cost of invasiveness and risks. The main focus is on anatomical variations, categorized as intrahepatic and extrahepatic. Intrahepatic variations involve duplications, atresia, and fusions of segmental ducts, while extrahepatic variations encompass duplications, atresia, and fusions of the cystic and common bile ducts. These variations, though often asymptomatic, can pose challenges during surgical interventions and may contribute to complications such as bile obstruction and infections. Understanding the anatomical variations of the biliary system is crucial for surgical planning and diagnostic accuracy, highlighting the importance of various imaging modalities in delineating these variations and optimizing patient care.
