Pregnancy increases the risk of gallstone formation due to physiological changes. While many gallstones resolve postpartum, understanding their cause is crucial for managing biliary issues during pregnancy.

Area of Science:

  • Obstetrics and Gynecology
  • Gastroenterology
  • Biliary Medicine

Background:

  • Pregnancy involves significant physiological alterations that can lead to pathological conditions.
  • Gallstone prevalence increases with parity, affecting 18.4%–19.3% of women with multiple pregnancies.
  • Gallstone formation during pregnancy occurs in 3%–8.1% of cases, with some resolving postpartum.

Purpose of the Study:

  • To investigate the incidence and characteristics of gallstones and biliary sludge during pregnancy.
  • To explore the physiological mechanisms contributing to gallstone formation in pregnant individuals.
  • To review the management strategies for biliary conditions in pregnancy.

Main Methods:

  • Analysis of population studies on gallstone prevalence in nulliparous and multiparous women.

  • Longitudinal follow-up of women throughout pregnancy to document gallstone neoformation.
  • Review of existing literature on the frequency and resolution of biliary sludge and gallstones postpartum.

    • Main Results:

    • Gallstone prevalence is significantly higher in parous women compared to nulliparous women.
    • New gallstones form in 3%–8.1% of pregnancies, with 20%–30% resolving after delivery.
    • Biliary sludge typically resolves postpartum, and gallstones/sludge are linked to biliary stasis and increased bile cholesterol saturation.

    Conclusions:

    • Pregnancy-induced physiological changes, including biliary stasis and increased cholesterol saturation, contribute to gallstone formation.
    • While many gallstones and biliary sludge resolve postpartum, conservative management is preferred during pregnancy.
    • Invasive procedures for biliary conditions, when necessary, are best tolerated during the second trimester.
