Sonographic Detection of Fetal Cholelithiasis

Area of Science:

• Perinatology
• Fetal Medicine
• Gastroenterology

Background:

• Fetal biliary lithiasis involves gallstones in the developing fetus, often found during routine obstetric ultrasound.
• The condition's incidence ranges from 0.03% to 2.3%.

Purpose of the Study:

• To review the incidence, risk factors, and management of fetal biliary lithiasis.
• To understand the spontaneous resolution and potential complications of fetal gallstones.

Main Methods:

• Literature review of fetal biliary lithiasis.
• Analysis of maternal and fetal risk factors.
• Summary of diagnostic and management strategies.

Main Results:

• Most cases of fetal cholelithiasis resolve spontaneously with an excellent prognosis.
• Identified maternal risk factors: placental abruption, high estrogen, diabetes, certain medications.
• Identified fetal risk factors: blood group incompatibility, congenital anomalies, genetic disorders, twin demise.

Conclusions:

• Fetal biliary lithiasis is typically a self-limiting condition.
• Awareness of risk factors aids in identification and monitoring.
• Complications are rare but necessitate further evaluation and potential intervention.
