Risk assessment of choledocholithiasis prior to laparoscopic cholecystectomy and its management options

Area of Science:

• Gastroenterology
• Surgical Risk Assessment
• Diagnostic Accuracy

Background:

• Accurate pre-operative risk evaluation for choledocholithiasis is vital for guiding management before laparoscopic cholecystectomy.
• Identifying patients with common bile duct stones ensures appropriate surgical planning and reduces potential complications.

Purpose of the Study:

• To evaluate the diagnostic accuracy of individual predictors and the Vilnius University Hospital Index (VUHI) for choledocholithiasis.
• To compare the effectiveness of different management strategies: cholecystectomy with intraoperative cholangiography versus endoscopic retrograde cholangiopancreatography (ERCP).

Main Methods:

• A retrospective study of 350 patients undergoing laparoscopic cholecystectomy for cholecystolithiasis.
• Investigation for concomitant choledocholithiasis using clinical data, imaging, and laboratory tests.
• Calculation of the VUHI score (A/30 + 0.4 × B, where A=total bilirubin, B=CBD diameter).

Main Results:

• The VUHI index demonstrated good diagnostic accuracy (71.1%), with higher detection rates in the high-risk group (76.2%) versus the low-risk group (39.6%).
• Dilated common bile duct (CBD) exhibited the highest sensitivity (92.5%) among individual predictors.
• ERCP showed superior diagnostic performance compared to intraoperative cholangiography, though ERCP complications were more frequent in patients without stones. No significant outcome differences were observed between management strategies.

Conclusions:

• The VUHI prognostic index offers valuable diagnostic accuracy for choledocholithiasis.
• Stratifying patients into only high- and low-risk groups is insufficient; an intermediate-risk category requiring further evaluation is identified.
• Both cholecystectomy with intraoperative cholangiography and ERCP are appropriate management strategies for choledocholithiasis.
