Congenital Cystic Lesion In Extra Hepatic Biliary Tract
Objective: To illustrate congenital cystic lesions of the extra hepatic biliary tract on the idea of information of embryologic development through the magnetic resonance cholangiopancreatography (MRCP).
Methods: Patients that were suspected to have been suffering from biliary disease were referred to the MRI units, there the patients were narrowed done to confirm with the inclusion and exclusion cri- teria, thereafter written and informed consent was obtained from them and the procedure was ex- plained to them in detail. MRCP was performed on a 1.5 Tesla in MR unit, using phased-array coil for signal detection. Heavily T2 weighted images were obtained with SSF-SE technique. The axial sec- tions were used for pancreatic and bile ducts whereas the coronal sections were used for the pancreatobiliary tract, axial and coronal source images and reformatted images were evaluated to- gether for the possibility of any anomaly in extra hepatic biliary tract. This was an observational, cross sectional, prospective study with a sample size of 377 patients. Statistical analysis was done by SPSS version 16.
Results: Choledochal cyst was found in 11 of the 377 patients with a gender separate frequency of 6 out of 196 females and 5 out of 181 males, with a total frequency of 2.9% and a p-value at <0.001 which was significant.
Conclusion: By identifying the inherent anomalies that present themselves during the visualization of the biliary tract through MRCP and MRI, while coupled with information regarding the clinical signifi- cance of every entity, is vital for establishing an accurate diagnosis and in guiding acceptable clinical intervention and management.
