DEVELOPMENTALANOMALIES AND MORPHOLOGICAL VARIATIONS OF GALL BLADDER- A CADAVERIC STUDY

Introduction- The Gall Bladder (GB) is a hollow viscus sac, situated in a fossa in the right hepatic lobe inferior surface. It extends from the right end of porta hepatis to the inferior border of liver. It is 7 - 10cm long, 3 cm broad and capacity is 30 – 50 ml. It has 3 parts Fundus, Body and Neck. Materials and Methods-This study was carried on 50 GB specimens in the Department of Anatomy, GITAM Institute of Medical Sciences & Research, Visakhapatnam. The GB was carefully dissected and cleaned to observe developmental anomalies and morphological variations of GB. Results-The developmental anomalies like Hartmann's pouch, Intrahepatic Hypoplastic GB were observed. The length and breadth GB ranged from 4.9 - 9.5 cm and 2.0 - 4.8 cm, shapes of GB most common pear shaped(64 %), flask shaped(20%), cylindrical shaped(12%) and hour glass(4%). Conclusion- The knowledge of this study will help the laparoscopic surgeon to take preventive measures before cholecystectomy and the radiologist to differentiate the normal from anomalies.
