What is the best management option for a 43-year-old lady with epigastric pain, taking proton pump inhibitors (PPI) over-the-counter (OTC), with an ultrasound showing a 2-3 mm gallstone?

Management of Small Gallstone in a Patient with Epigastric Pain

Repeat ultrasound after fasting for 8 hours is the best option for this 43-year-old woman with epigastric pain and a small 2-3 mm gallstone found on initial ultrasound. 1

Rationale for Repeat Ultrasound

• The initial ultrasound was performed without proper fasting protocol, which is essential for accurate gallstone diagnosis
• Small gallstones (2-3 mm) require careful confirmation as they may represent:
  • True gallstones requiring intervention
  • Sludge or artifacts that may disappear with proper preparation
  • Incidental findings unrelated to the patient's epigastric symptoms

Decision-Making Algorithm

1. First step: Confirm diagnosis with proper imaging

   • Repeat ultrasound after 8-hour fast to confirm the presence and characteristics of the gallstone 1
   • Assess for additional signs of gallbladder inflammation (wall thickening, pericholecystic fluid)
   • Evaluate for biliary dilatation that might suggest obstruction

2. After confirmation, determine if symptoms are truly biliary

   • Biliary colic typically presents as episodic right upper quadrant or epigastric pain
   • Pain often occurs after fatty meals and lasts 30 minutes to several hours
   • Epigastric pain with irregular PPI use may suggest acid-related disorder rather than biliary disease 2

3. Treatment selection based on symptom correlation

   • If symptoms are clearly biliary and stone is confirmed: Consider laparoscopic cholecystectomy 3
   • If symptoms are likely non-biliary: Address alternative diagnoses (acid reflux, functional dyspepsia)
   • If uncertain correlation: Trial of conservative management with scheduled follow-up

Why Not Immediate Cholecystectomy?

• Laparoscopic cholecystectomy is the gold standard for symptomatic gallstone disease 3, but:
  • Small stones (2-3 mm) may not be causing the patient's symptoms
  • The patient's irregular PPI use suggests possible acid-related disorder 2
  • Unnecessary cholecystectomy carries surgical risks without resolving symptoms 4
  • Up to 40% of patients with gallstones and upper abdominal pain may have unrelated causes for their symptoms 4

Why Not Conservative Management with PPI & Rowachol?

• Conservative management may be appropriate after proper diagnosis, but:
  • Diagnosis needs confirmation with proper fasting ultrasound first
  • PPIs can actually reduce gallbladder function (58% of patients on PPIs show gallbladder motor dysfunction) 2
  • Rowachol has limited effectiveness and is only suitable for small, radiolucent stones in highly selected patients 1

Important Considerations

• If repeat ultrasound confirms gallstone and symptoms are clearly biliary, early laparoscopic cholecystectomy is safe and effective 3, 5
• If symptoms persist despite negative findings on repeat ultrasound, further evaluation for other causes of epigastric pain is warranted
• Watchful waiting with proper diagnostic investigation is supported by evidence when correlation between symptoms and gallstones is uncertain 4

Caveat

• If the patient develops signs of acute cholecystitis (fever, persistent RUQ pain, positive Murphy's sign) or complications, immediate surgical evaluation is warranted regardless of stone size 3

By following this approach, you ensure proper diagnosis before committing to invasive treatment or dismissing potentially significant pathology.
