What are the typical clinical presentations of gall bladder stones?

Clinical Presentation of Gallbladder Stones

The characteristic presentation of symptomatic gallbladder stones is severe, steady epigastric and/or right upper quadrant pain that radiates to the upper back or right shoulder, lasting hours (not minutes), often accompanied by nausea and vomiting. 1, 2

Asymptomatic vs. Symptomatic Disease

• Approximately 80% of patients with gallstones remain asymptomatic throughout their lives, discovered incidentally on imaging performed for other reasons 1
• Among asymptomatic patients at diagnosis, only 2-5% annually develop biliary pain during initial follow-up years 3
• Once symptomatic at discovery, patients experience a more severe course with 6-10% suffering recurrent symptoms annually 3

Classic Biliary Colic Presentation

Pain characteristics that distinguish true biliary colic:

• Severe, steady pain (not fluctuating or colicky despite the name) located in the epigastrium and/or right upper quadrant 1, 4
• Duration of at least 15 minutes, typically lasting 2-4 hours, and may persist up to a day 5, 6, 3
• Radiation to the upper back, right shoulder, or right supraclavicular region 2, 4, 7
• Abrupt onset, often awakening patients from sleep 3
• Unaffected by position changes, antacids, or passage of gas 1, 4
• Associated nausea and vomiting are common 2, 7

Common Pitfall to Avoid

Do not attribute non-specific dyspeptic symptoms (indigestion, flatulence, heartburn, bloating, belching) to gallstones—these are unlikely to resolve with cholecystectomy and frequently persist after surgery. 4, 3 These symptoms occur commonly in persons with gallstones but are probably unrelated to the stones themselves 3.

Acute Cholecystitis Presentation

When gallstones cause acute cholecystitis (occurring in 1-3% of symptomatic gallstone patients), additional findings include: 8

• Right upper quadrant pain and tenderness 1, 2
• Murphy's sign: focal tenderness when palpating the gallbladder area during deep inspiration 2, 4
• Fever indicating infection or inflammation 2
• Leukocytosis 8, 2
• Anorexia 2

Complicated Gallstone Disease Presentations

Common bile duct stones (choledocholithiasis) present with:

• Epigastric or right upper quadrant pain associated with jaundice and/or fever 2
• Elevated bilirubin, alkaline phosphatase, and GGT levels indicating biliary obstruction 2

Gallstone pancreatitis:

• Gallstones cause up to 50% of acute pancreatitis cases 2
• Risk is greater with multiple small stones 3

Diagnostic Approach

Ultrasound is the first-line imaging modality with 96% accuracy for gallstone detection, showing: 1, 2, 4

• Gallstones visualized directly 2
• In acute cholecystitis: gallbladder wall thickening and edema, pericholecystic fluid, distended gallbladder 2
• Sonographic Murphy's sign (though with relatively low specificity) 2

Critical diagnostic pitfall: Do not rely solely on absence of sonographic Murphy sign to rule out acute cholecystitis if the patient received pain medication prior to imaging. 4

Risk Stratification

Predictors of future biliary complications include:

• History of pain at diagnosis (strongest predictor) 3
• Female gender 3
• Obesity 3
• Large solitary stones (higher risk of acute cholecystitis) 3
• Multiple small stones (higher risk of biliary pancreatitis) 3

In patients not undergoing cholecystectomy after initial acute cholecystitis, gallstone-related complications occur at 14%, 19%, and 29% at 6 weeks, 12 weeks, and 1 year respectively. 1
