Summary
Preoperative endoscopic ultrasonography (EUS) accurately images the common bile duct (CBD) and diagnoses CBD stones. This imaging helps select appropriate treatment, avoiding unnecessary procedures before gallbladder removal.
Area of Science:
- Gastroenterology
- Surgical Imaging
- Hepatobiliary Surgery
Background:
- Biliary tract imaging is crucial before laparoscopic cholecystectomy in patients with high likelihood of common bile duct (CBD) stones.
- Endoscopic ultrasonography (EUS) is a potential imaging modality for the CBD in this high-risk population.
Purpose of the Study:
- To compare immediate preoperative EUS with intraoperative cholangiography for CBD imaging and diagnosis of CBD stones.
- To evaluate EUS performance in patients at high risk for choledocholithiasis.
Main Methods:
- Fifty patients with symptomatic choledocholithiasis underwent preoperative EUS in the operating room before laparoscopic cholecystectomy.
- Diagnoses of CBD stones were confirmed by instrumental exploration.
- Absence of stones was confirmed by negative imaging and 3-month clinical monitoring.
Main Results:
- EUS visualized the CBD in 100% of cases.
- CBD stones were detected in 24% of patients.
- EUS demonstrated 100% sensitivity, 97% specificity, 92% positive predictive value, and 100% negative predictive value for CBD stones.
Conclusions:
- Immediate preoperative EUS is highly effective for diagnosing CBD stones in high-risk patients.
- EUS can guide treatment selection, potentially avoiding unnecessary invasive CBD exploration during laparoscopic cholecystectomy.
