Anatomy & Pathophysiology

Gallbladder anatomy
  • Gallstones are classified as cholesterol stones and pigmented stones (black and brown), and are present in approx 20% of females and 8% of males in the United States
  • These stones cause the majority of all biliary tract problems, and depending on where the stone become impacted, specific problems occur.
  • Bile flows out the gallbladder, down the cystic duct into the common bile duct, and ultimately into the 1st portion of the duodenum.
