In utero development of the fetal gall bladder in the Korean population.

Moon MH, Cho JY, Kim JH, Lee YH, Jung SI, Lee MS, Cho HC - Korean J Radiol (2008 Jan-Feb)

Bottom Line: The measured parameters from the fetal gall bladder had a significant positive relationship with gestational age (p = 0.000 for all cases), and the correlation of length and area with the gestational age (r = 0.741 and r = 0.690, respectively) was better than the correlation of width, height, and volume with gestational age.The median length of the fetal gall bladder in the Korean population was not significantly different from the mean length of gall bladders in the Caucasian and African-American populations (p = 0.915).We have provided reference values for the fetal gall bladder throughout the gestation period in the Korean population.

ABSTRACT

Objective: To provide reference ranges of the fetal gall bladder in the Korean population.

Materials and methods: Fetal gall bladder development was evaluated in well-dated, non-anomalous fetuses in the Korean population between February and April 2003 and the visualization rate and reference values were determined from the obtained data.

Results: The visualization rate of the fetal gall bladder increased as gestation advanced to a plateau above 90%, which was maintained between 16 and 34 weeks. The measured parameters from the fetal gall bladder had a significant positive relationship with gestational age (p = 0.000 for all cases), and the correlation of length and area with the gestational age (r = 0.741 and r = 0.690, respectively) was better than the correlation of width, height, and volume with gestational age. The repeatability coefficients and coefficients of variation between the two operators were 5.56 mm and 12.9% for the length and 344.11 mm(2) and 33.52% for the area. The median length of the fetal gall bladder in the Korean population was not significantly different from the mean length of gall bladders in the Caucasian and African-American populations (p = 0.915).

Conclusion: We have provided reference values for the fetal gall bladder throughout the gestation period in the Korean population.

Figure 2: Visualization rate of the fetal gall bladder according to gestational age.

Mentions: Sonographic visualization and measurement of the fetal gall bladder was possible at as early as 12 weeks gestation. Our study population consisted of 1,911 of the 2,170 fetuses enrolled in this study (88.1%) that produced results meeting the acceptable criteria. Of these, the gall bladders of 1,417 fetuses (74.1%) were visualized using antenatal sonography. Visualization of the gall bladder was achieved in greater than 90% of women at gestation periods between 16 and 34 weeks, however the gall bladder was identified in less than 90% of study population after 35 weeks (Fig. 2). Measurements of the length, width, and height of the fetal gall bladder were obtained from 1,292 of 1,417 fetuses (91.2%), however the scanning plane could not be adjusted to depict the maximal length, width, or height of the gall bladder in the remaining 125 fetuses. Table 1 shows fetal gall bladder length, height, width, area and volume according to gestational age. The measured parameters of the fetal gall bladder had a significant positive relationship with gestational age (Table 2). The correlation of length and area to gestational age was better than that of width, height, and volume, therefore, reference values based on the gestational age were only calculated for the length and area (Table 3). The median values of the gall bladder lengths in the Korean population were not significantly different from those in the Caucasian and African-American populations (p = 0.915).
