title: Ultrasonographic confirmation of acute biliary obstruction at term gestation.
abstract: We report a case of acute biliary obstruction diagnosed by ultrasonography at term gestation. Intraoperative findings included a massively dilated biliary collecting system and an impacted stone at the ampulla of Vater. The use of ultrasonography in this patient supports the expanding role of this diagnostic tool for nonobstetric complications of pregnancy.
