Gallbladder Volume in Sikkimese Population.
Background Gall bladder volume can have clinical and therapeutic implications and possibly affect certain pathophysiological mechanisms of many diseases affecting the gallbladder including gall stones. Objective The objective of the study was to establish baseline indices of gallbladder volume for the Sikkimese population and determine its correlation with age, sex and Body Mass Index. Method A prospective epidemiologic study on selected 100 patients (equal male to female ratio) over the age of 36 years, undergoing ultrasound scan of abdomen, was undertaken. Age, Sex, Body Mass Index and gall bladder volume for each subject were collected and analysed statistically. Spearman's correlation test was performed to look for significant variables. Result The overall mean gallbladder volume in the present study was 15.47±7.9 ml with 17.2±8.9 ml and 13.74±6.4 ml being average volumes in males and females respectively, which gives the baseline indices for the Sikkimese population. Gall bladder volume was strikingly increased in obese subjects. There was a positive correlation between gall bladder volume and age (r=0.114), gender (r=0.182) and BMI (r= 0.175) but the strength of correlation was weak and not statistically significant (p <0.001). Conclusion Ultrasonography is an easy and effective method for evaluation of gall bladder volume. Sikkimese males have a larger fasting gall bladder volume which is directly correlated with higher body mass index. Fasting gall bladder volume has a weak correlation with advancing age.
