Pregnant patient with imaging demonstrating gallstones

ALT: alanine aminotransferase; AST: aspartate aminotransferase; CBC: complete blood count; ERCP: endoscopic retrograde cholangiopancreatography; HELLP: Hemolysis, Elevated Liver enzymes, Low Platelet count.

* Laboratory evaluation is usually normal in patients with uncomplicated gallstone disease; abnormal laboratory tests suggest the development of complicated gallstone disease or other pregnancy- or non-pregnancy-related conditions. We perform the following baseline evaluation:

• AST/ALT, total bilirubin, alkaline phosphatase (to evaluate for complicated gallstone disease, HELLP, and preeclampsia)
• Serum amylase and lipase (to evaluate for pancreatitis)
• CBC (to evaluate for infection, HELLP, and preeclampsia)
• Urine protein (to evaluate for preeclampsia)

¶ Some of our contributors do not delay surgery until the postpartum period and rather offer cholecystectomy to all patients with biliary colic (even if only a single episode).
