The association between volume of the gallbladder based on sonographic findings and demographical data in patients referred to Guilan cohort center, Iran

Background: Determining the change in the size, structure and volume of the gallbladder by Ultrasound as a diagnostic method is clinically important due to possibility of stone formation in certain diseases and physiological conditions, especially in susceptible people who have a large gallbladder volume. Therefore, this study was carried out by examining the volume of the gallbladder with ultrasound and its association with patients’ demographic data in the Guilan cohort population. Methods: : In this cross-sectional study total number of 950 patients aged 35-60 years participated to determine the volume of the gallbladder by a radiologist based on the ultrasound method. Demographic data were collected by questioner according to the ultrasound was performed after fasting for at least 12 hours. Results: : The results showed that there was a statistically significant association between marriage and gender with the presence or absence of lesions in the studied patients (P<0.05). Also, there was a statistically significant relationship between BMI, sex, marriage, smoking, and alcohol consumption with the average volume of the gallbladder in the studied patients (P0.05). Conclusion: According to our results, the volume of the gallbladder is greater in obese men than in women. Also, the volume of the gallbladder increases with age, alcohol consumption, and smoking.
