Gallstones

Gallstones are hardened deposits that form in the gallbladder. Most never cause symptoms, but stones that block the cystic duct or common bile duct can trigger biliary colic, acute cholecystitis, jaundice or pancreatitis.

Overview

Gallstones form when bile components crystallize inside the gallbladder. NIDDK estimates that 10–15% of the U.S. population has gallstones, roughly 25 million people. Most are silent. [1]

Symptoms begin when a stone blocks bile flow. A transient blockage can produce biliary colic; persistent obstruction can cause acute cholecystitis or other complications. [2]

Symptoms and warning signs

A typical gallbladder attack causes pain in the upper right abdomen and may last several hours. Nausea or vomiting can accompany the pain. Fever, jaundice, dark urine, pale stool or pain that persists for hours can indicate a complication. [2]

SYMPTOM MATRIX

Silent gallstones and complicated gallstone disease are very different

Persistent pain, fever or jaundice needs medical assessment rather than routine self-care.

Biliary tract
Gallbladder attack
  • Upper-right abdominal pain
  • Pain after a heavy meal
  • Pain lasting minutes to hours
  • Nausea or vomiting
  • Recurrent episodes
Can also occur
  • No symptoms at all
  • Upper-middle abdominal pain
  • Pain radiating toward back or shoulder
  • Bloating or food-related discomfort
Possible complication
  • Pain lasting several hours
  • Fever or chills
  • Jaundice
  • Dark urine or pale stools
  • Persistent vomiting

These features can indicate gallbladder inflammation, bile-duct obstruction or pancreatitis.

Diagnosis

History and examination are followed by laboratory and imaging tests when gallstone disease is suspected. Ultrasound is the preferred imaging test for gallbladder stones. Blood tests can show infection, inflammation or liver and pancreatic abnormalities. [3]

MRCP or endoscopic ultrasound can evaluate the bile ducts when common-bile-duct stones are suspected. ERCP is generally reserved for therapeutic management of duct stones rather than routine diagnosis. [3] [4]

Diagnostic pathway

Start with ultrasound and assess for duct obstruction

The key distinction is between uncomplicated gallbladder stones and stones causing inflammation or obstruction.

Biliary assessment
1History and examClarify biliary-colic pattern and look for fever, jaundice or persistent tenderness.
2Blood testsAssess liver tests and evidence of inflammation or pancreatitis.
3UltrasoundLook for gallbladder stones and signs of complication.
4Evaluate bile ductsUse MRCP, EUS or therapeutic ERCP when duct stones are suspected.

Complications of gallstones

Gallstones can cause acute cholecystitis, common-bile-duct stones, cholangitis and gallstone pancreatitis. Fever, jaundice, persistent severe pain or systemic illness changes the problem from routine biliary colic to urgent gallstone disease. [2] [3]

Treatment and management

Silent gallstones usually do not need treatment. For symptomatic gallbladder stones, the usual definitive treatment is laparoscopic cholecystectomy. People can live without a gallbladder because bile flows directly from the liver to the intestine. [4]

Stones in the common bile duct may be removed with ERCP, often in connection with cholecystectomy. Treatment timing depends on whether there is cholecystitis, pancreatitis, cholangitis or another complication. [4] [5]

Treatment & care hub

Treat symptoms and complications, not silent stones

Management is driven by whether stones are causing pain, obstruction or inflammation.

Gallstone management
ObservationSilent stones

No routine treatment for asymptomatic stones

Incidentally found gallstones in an otherwise normal gallbladder usually do not require treatment.

CholecystectomySymptomatic disease

Remove the gallbladder

Laparoscopic surgery is the usual definitive treatment for recurrent symptomatic gallbladder stones.

ERCPDuct stones

Clear the common bile duct

Endoscopic treatment can remove obstructing common-bile-duct stones in selected patients.

Urgent careComplications

Treat infection or pancreatitis

Cholecystitis, cholangitis and gallstone pancreatitis require hospital-based assessment and treatment.

Living without a gallbladder

The gallbladder is not essential. After removal, bile flows continuously from the liver into the intestine. Most people return to a normal diet, although some have temporary digestive changes during recovery. [4]

United States estimate

Gallstones affect about 10–15% of the U.S. population

NIDDK estimates nearly 25 million people in the United States have gallstones.
