Implication

Prospective study compares intraoperative ultrasound and cholangiography for detecting choledocholithiasis, suggesting ultrasound as a reliable option.

Key Points

The study aimed to compare the diagnostic performance of intraoperative ultrasound and cholangiography for detecting choledocholithiasis.
Prospective, single-center study
Included patients at intermediate or high risk of choledocholithiasis
All patients underwent both intraoperative ultrasound and cholangiography
Analyzed diagnostic accuracy, procedure duration, and intraoperative findings using cholangiography as the reference standard
Total of 30 patients included
Intraoperative ultrasound visualized biliary anatomy in 96.7% of cases
Of 10 patients with choledocholithiasis, ultrasound identified 9 cases yielding sensitivity of 90% and specificity of 100%
Cholangiography detected 7 cases with sensitivity of 70% and specificity of 100%
Procedure time for ultrasound was significantly shorter (5.6 min) compared to cholangiography (12.5 min)
No postoperative complications or readmissions occurred
