Observational evaluation compares detection of gallstones during cholecystectomy using two imaging techniques, indicating implications for practice.
Key Points
This evaluation aims to compare the efficacy of intraoperative ultrasound and cholangiogram in detecting gallstones in the common bile duct during cholecystectomy.
Conducted an observational cohort evaluation involving all patients undergoing cholecystectomy with CBD imaging in 2023.
Categorized patients into two groups based on the imaging technique used: OTC or IOUSS.
Collected data on patient characteristics, procedural details, and retained stones over at least 12 months follow-up.
In total, 1016 patients underwent cholecystectomy; 511 received intraoperative bile duct imaging (333 OTC, 178 IOUSS).
Surgery duration for OTC was longer (87.3 min) compared to IOUSS (74.7 min, p<0.001).
OTC demonstrated a sensitivity of 96.2% and specificity of 97.6%, while IOUSS showed 100% sensitivity and 96.6% specificity.
