Abstract :

 INTRODUCTION: The liver is the largest gland of digestion and occupies the right hypochondria and epigastric regions of the abdomen. The ductular or transport system comprises intra and extra–hepatic biliary systems of which the latter forms the subject of our study. Awareness of “morphometric and incidence of anatomical variations in the Gall Bladder (GB), Cystic Duct (CD) & Common Bile Duct (CBD) ” is important to surgeons, radiologists, and clinicians in general. Ultrasound is widely available, easy–to–use and less expensive than other imaging methods, that is the reason we choose this method for this study. MATERIAL AND METHODS: This study was conducted with 225 patients (The number of adult patients is 159 and the pediatric age group patients are 66) at the department of Radiology, Osmania General Hospital, Hyderabad who attended the Gastroenterology outpatient unit. All the patients were included in the study particularly morphometric and incidence of anatomical variations in the Gall Bladder (GB), Cystic Duct (CD) & Common Bile Duct (CBD). OBSERVATIONS AND RESULTS: The visibility in the adult patients (159) was 100% for Gallbladder i.e.159 cases: 3.77% for CD, number of cases being 6: and 89.94% for CBD, the number of cases being 143. The diameter of these visualized components is in the range of 0.8mm to 12mm(CD,CBD). Out of the total 225 patients included in this study the author diagnosed only one case of Double Gallbladder which comes to the percentage of 0.4%. CONCLUSION: The sample comprised 107 males and 118 females in the ratio of 0.9 to 1.0. The author could visualize the ductal system in only 40% of the cases and gallbladder in 100% of cases. Visualization of Extra Hepatic Biliary Apparatus (EHBA) component parts was better in the pediatric group than in the adult group In our study we could not report any congenital anomaly in the pediatric group. However there was a double gallbladder in the adult group.
