🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the
last 12 months.
|
World Journal of Surgery (2025) - Systematic Review and Meta-analysis
Key Findings
- For identifying high-risk choledocholithiasis, ASGE 2019 and ESGE 2019 had only moderate sensitivity at 63% and 62%, with specificities of 75% and 82%, showing limited ability to select patients for upfront ERCP.
- For ruling out stones in low-risk patients, ASGE 2019 and ESGE 2019 reached sensitivities of 95% and 84%, and overall discrimination was better with ASGE 2019 and ESGE 2019 than with ASGE 2010 (AUC 0.74, 0.73, and 0.65).
📋 Practice Implication: Use guideline stratification primarily to clear low-risk patients for cholecystectomy without extra duct imaging, and confirm most high-risk calls with imaging rather than sending directly to ERCP.

Journal of Gastroenterology and Hepatology (2025) - Systematic Review and Meta-analysis
Key Findings
- Across nine cohorts with 3338 patients, spontaneous common bile duct stone passage occurred in 15.7% of imaging-confirmed cases, and the mean stone size among those with passage was 3.77 mm.
- Spontaneous passage was more likely with a single stone (risk ratio 1.63, 95% CI 1.51-1.76) and with smaller duct diameter and stone size (SMD -0.52 and -0.91), while sex, cholangitis, and pancreatitis showed no significant differences.
📋 Practice Implication: When imaging shows a small solitary distal stone and the patient is clinically improving, reassess before ERCP because a meaningful minority will have already passed the stone.

Journal of Gastrointestinal Surgery (2026) - Meta-analysis
Key Findings
- In 16 randomized trials with 1576 patients, preoperative EST plus laparoscopic cholecystectomy achieved higher bile duct stone clearance than laparoscopic common bile duct exploration plus cholecystectomy (OR 1.72, 95% CI 1.14-2.60).
- Laparoscopic common bile duct exploration plus cholecystectomy lowered recurrence (OR 0.27, 95% CI 0.11-0.69) and reduced overall costs by about 2059 US dollars, while overall complications, mortality, hospital stay, and residual stone rates were similar.
📋 Practice Implication: If local surgical expertise in laparoscopic duct exploration is strong, a one-stage operative strategy is reasonable when long-term recurrence reduction and lower total episode cost matter more than marginally higher initial clearance.

BMC Surgery (2026) - Systematic Review and Meta-analysis
Key Findings
- Across 12 randomized trials with 1238 patients, the one-stage intraoperative ERCP approach had lower postoperative morbidity than the two-stage preoperative ERCP strategy (RR 0.58, 95% CI 0.35-0.95).
- The one-stage approach reduced hospital stay by 2.85 days (P < 0.001), whereas the two-stage strategy had a 28.6-minute shorter operative time (P = 0.0007); overall success favored the one-stage pathway numerically without a significant difference.
📋 Practice Implication: For centers that can coordinate laparoscopy and ERCP in the same session, prioritize a one-stage pathway to reduce postoperative complications and shorten admission.

The Journal of Trauma and Acute Care Surgery (2025) - Randomized Trial
Key Findings
- In 84 patients with complex large bile duct stones, cholangioscopy-guided lithotripsy produced higher clinical success than extracorporeal shock wave lithotripsy (88% vs 69%, P = 0.01), while technical success was similar (100% vs 92.85%, P = 0.19).
- Cholangioscopy-guided lithotripsy required fewer ERCP sessions (1.13 vs 2.32) and fewer lithotripsy sessions (1.13 vs 2.3), with similar adverse events apart from more cutaneous petechiae after shock wave therapy.
📋 Practice Implication: For difficult or impacted duct stones that fail standard extraction, move to cholangioscopy-guided lithotripsy when available rather than defaulting to shock-wave lithotripsy.

💡
Summary
Recent choledocholithiasis evidence supports more selective ERCP use: contemporary guideline meta-analysis shows current ASGE and ESGE pathways are better at ruling out low-risk disease than identifying patients who truly need upfront ERCP, and spontaneous passage occurs in roughly one in six imaging-confirmed cases, especially when stones are small and solitary. For definitive management, newer comparative data favor tailoring single-stage strategies to local expertise, with one-stage laparoscopic-endoscopic approaches reducing morbidity or recurrence and cholangioscopy-guided lithotripsy outperforming shock-wave lithotripsy for complex stones.
