Determination of anatomical variations of cystic duct in magnetic resonance cholangiography exposure.
Pak J Surg Jan ;31(1):25-8.

Objective: To assess the frequency of Anatomical variations of Cystic duct through Magnetic Resonance Cholangiography (MRC) in gender groups in our patient population. Study design: Cross Sectional study. Place and Duration: A cross sectional study was carried out at the department of Anatomy, Institute of Basic Medical Sciences (IBMS), Dow University of Health Sciences (DUHS) from May 2011 to December 2013 in collaboration with radiological department of Agha Khan University Hospital (AKUH) and (DUHS). Methodology: Th e samples of the study were collected by Non probability, purposive sampling. Total 376 diagnosed cases of biliary disease booked for MRC were included in the study. Aft er taken informed consent of radiological departments of AKUH and DUHS. MRC performed in Magnetic Resonance Image (MRI) unit on MRI scanner and images were obtained by using 1.5 TESLA. Th e information of Anatomy visualize on imaging fi lm was noted. Over all frequencies of cystic duct tract variation were assessed and documented. Results: Out of 376 patients included in our study, there were 196 males and 180 females. Th e variations were found in11.7 % cases. We found 7.1 % variations in male and 4.6% in female gender groups. Th e most observed frequency was low insertion of cystic duct and least observed frequency was Short cystic duct. Conclusion: It is concluded that several cystic duct variations were identifi ed in our population by using a simple, non invasive method, MRC. Clarifi cation of the Anatomy of theses variations of biliary tract will be the safe approach prior to surgery.
