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

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.

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.

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.
|
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.
