Clinical Trial Summary

Background. X-ray cholangiography has a high sensitivity and specificity of detecting bile duct stones and is the gold standard. There are no studies describing the sensitivity and specificity of IFC for bile duct stone detection.

Research question. What is the sensitivity of IFC to visualize bile duct stones? Method. Prospective study with 40 patients undergoing planned laparoscopic cholecystectomy with preoperative magnetic resonance cholangiopancreatography (MRCP) (gold standard) and intraoperative IFC, X-ray cholangiography and choledochuscopy in that order.

Primary outcome. Sensitivity of visualization of bile duct stone by fluorescent cholangiography and secondary outcome is visualization of anatomy.
