Gallbladder disease (main)

Background

Gallbladder disease types

Gallbladder anatomy (overview).

Gallbladder anatomy

• Symptomatic cholelithiasis (biliary colic)
• Choledocholithiasis
• Acute calculous cholecystitis
• Ascending cholangitis
• Acalculous cholecystitis
• Biliary atresia
• Cholestasis of pregnancy

Anatomy & Pathophysiology

• 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.

Clinical Features

• RUQ pain
• Additional features vary by pathology
