Estimation of gestational age from gall-bladder length.

Area of Science:

• Forensic Science
• Obstetrics
• Anatomy

Background:

• Accurate estimation of gestational age is critical in forensic investigations, particularly in cases of infanticide and illegal abortions.
• Traditional methods for determining fetal age can be unreliable with fragmented, decomposed, or eviscerated remains.

Purpose of the Study:

• To investigate the potential of fetal gall-bladder length as a novel biometric parameter for estimating gestational age.
• To establish a statistically validated correlation between gall-bladder length and fetal age.

Main Methods:

• Dissection of fetuses across various gestational age groups.
• Precise measurement of gall-bladder length.
• Statistical analysis to determine correlation and reliability.

Main Results:

• A significant statistical correlation was confirmed between fetal gall-bladder length and gestational age.
• The gall-bladder length measurement demonstrated a reliable method for age estimation.

Conclusions:

• Fetal gall-bladder length provides a valuable and novel method for estimating gestational age.
• This technique is particularly useful as an additional parameter in forensic scenarios involving compromised fetal remains, enhancing accuracy.
