🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the last 12 months.

1. Asymptomatic gallstones: Cumulative incidence proportion, incidence rate, and risk factors for symptoms development: Systematic review and meta-analysis.

PloS one (2026) - Meta-Analysis

Key Findings

  • Symptomatic progression increased over time, with cumulative incidence of 10% at 5 years, 19% at 10 years, and 26% at 15 years.
  • Alcohol consumption increased symptom risk (RR 1.32, 95% CI 1.27-1.38), and hyperlipidemia also increased risk (RR 1.19, 95% CI 1.07-1.32).

📋 Practice Implication: Incidental gallstones can usually be observed, but patients with alcohol use or hyperlipidemia warrant more explicit counseling about symptom progression.

2. Performance of Diagnostic Guidelines in the Evaluation of Choledocholithiasis in Patients With Acute Biliary Presentation: A Systematic Review and Meta-Analysis.

World journal of surgery (2025) - Meta-Analysis

Key Findings

  • For high-risk choledocholithiasis classification, pooled specificity improved from 57% with ASGE 2010 to 75% with ASGE 2019 and 82% with ESGE 2019.
  • Low-risk classification was highly sensitive for excluding common bile duct stones, reaching 97% with ASGE 2010 and 95% with ASGE 2019.

📋 Practice Implication: Guidelines are most useful for ruling out duct stones in low-risk patients, while high-risk labels should not automatically trigger ERCP without confirmatory context.

3. Comparative Risk of Gallstone Formation After Sleeve Gastrectomy and Roux-En-Y Gastric Bypass: A Systematic Review and Meta-Analysis.

Obesity surgery (2025) - Meta-Analysis

Key Findings

  • Sleeve gastrectomy was associated with lower gallstone formation than Roux-en-Y gastric bypass (OR 0.68, 95% CI 0.53-0.88; p = 0.003).
  • The lower risk with sleeve gastrectomy was evident before 2 years of follow-up (OR 0.59, 95% CI 0.42-0.82) but not at 2 years or longer (OR 0.84, 95% CI 0.55-1.28).

📋 Practice Implication: Bariatric procedure choice should include short-term gallstone risk counseling, with closer prevention planning for Roux-en-Y patients during early rapid weight loss.

4. Preventing Unnecessary Endoscopic Retrograde Cholangiopancreatography in Patients With Spontaneous Bile Duct Stone Passage: A Systematic Review and Meta-Analysis.

Journal of gastroenterology and hepatology (2025) - Meta-Analysis

Key Findings

  • Spontaneous common bile duct stone passage occurred in 15.7% of patients with imaging-confirmed stones (95% CI 11.5%-21.2%).
  • Passage was associated with younger age, smaller common bile duct diameter, smaller stone size, single stones (RR 1.63, 95% CI 1.51-1.76), and longer time to ERCP.

📋 Practice Implication: Selected patients with small, solitary duct stones and improving features may be candidates for short-interval reassessment before committing to ERCP.

5. Metabolic Score for Visceral Fat and Gallstone Disease Risk: A Multicenter Cohort Study and Mediation Analysis of Inflammatory Biomarkers.

Journal of digestive diseases (2026) - Multicenter Cohort Study

Key Findings

  • Gallstone disease risk increased by 84% for each 1-unit increase in METS-VF and by 57% for each 1-standard deviation increase.
  • Compared with the lowest METS-VF quartile, pooled hazard ratios rose stepwise across Q2, Q3, and Q4: HR 1.65, HR 2.16, and HR 3.00, respectively.

📋 Practice Implication: Visceral adiposity metrics may help identify patients who need earlier gallstone risk counseling as part of metabolic disease management.

💡 Summary

Recent cholelithiasis literature emphasizes risk-stratified observation, selective duct evaluation, and prevention of procedure-related morbidity. The strongest signals support counseling asymptomatic patients by long-term progression risk, avoiding upfront ERCP when guideline specificity is limited or spontaneous passage is likely, and tailoring bariatric and metabolic risk discussions to measurable gallstone predictors.
