Role of magnetic resonance cholangio Pancreatography in the evaluation of normal Anatomical variations and anomalies in Branching pattern of biliary system -hospital Based 1 year observational study

Abstract

BACKGROUND Biliary tree systems have many anatomical variants and anomalies, thorough knowledge of anatomical variants and anomalies of the biliary tree is of paramount importance as there is a substantial increase in the operative procedures being performed on the biliary tree, such as resection and replacement of liver, drainage of biliary obstructions and radiological interventional procedures.

Bile duct injuries are frequently associated with surgical intervention procedures due to no prior knowledge of the variations in the anatomy of the biliary system. Wrong evaluation of the biliary anatomic variations might lead to inadvertent ligature or aberrant ducts section can lead to significant complications like leakage of bile or atrophy of the residual liver. Thus, accurate information of the anatomy of the biliary tree and its variants frequency is critically important during surgical procedures, especially when it comes to anatomic areas with high rates of variations, such as the hepatobiliary system. Magnetic Resonance Cholangiopancreatography (MRCP) is a non-invasive modality, doesn’t require contrast, lack of exposure to radiation that can produce highly accurate images and provide knowledge of biliary tree anatomical variations and anomalies.

The purpose of the study is to identify the normal structural variations and anomalies in the branching pattern of the bile ducts by using Magnetic Resonance Cholangiopancreatography
