Gall stone in pregnancy.
Gallbladder disease is four times as common in women as in men, and pregnancy appears to contribute to the development of gallstones. During pregnancy, most women receive ultrasound scans, which are highly sensitive in detecting gallstones. The study was undertaken to evaluate the prevalence of gallstones among the pregnant woman. The aim was to determine any significant difference in the prevalence of gallstone among the pregnant woman compared to the generalized prevalence of gallstone in our community.


METHODS
The maternal gallbladder was examined in 1336 consecutive obstetric ultrasound scans performed for medical indications at 3rd trimester of pregnancy. The study was conducted in Centre for Nuclear Medicine and Ultrasond (CNMU) Mymensingh on randomly selected subjects, among those who came here for ultrasound evaluation of pregnancy. 500 control were taken from age group between 20-30 yrs who came here for ultrasound examination of lower abdomen other than pregnancy.


RESULTS
Gallstone were found in total one hundred eight cases. Prevalence of gallstone in pregnant woman was 8.08% (n=108). The age ranges were 20 to 45 yrs with mean age of 28.21 +/- 4.95 (mean +/- SD) yrs. The highest prevalence (12.71%) were seen in 3rd or higher gravida group with mean age of 30.32 +/- 4.74 yrs. Significantly higher cases of gallstone were found in multiparity compared to control population of same age group. CONCLUSIONS. Repeated pregnancy causes increased gallstone formation due to changes in gallbladder kinetics leading to stasis and stone formation.
