Promising Initial Experience With Intra-operative Fluorescent Cholangiography

May 8, 2014 updated by: Søren S. Larsen, Hvidovre University Hospital

Intraoperative fluorescent cholangiography (IFC) with concomitant fluorescent angiography is a recently developed method for non-invasive visualisation of the relevant anatomy during laparoscopic cholecystectomy. The objective of this study was to assess the time required by routine-use of IFC and to evaluate success-rate of the procedures.

Methods Thirty-five patients scheduled for laparoscopic cholecystectomy and operated by the same surgeon were consecutively enrolled. A standardized protocol with IFC including concomitant angiography was performed during laparoscopic cholecystectomy. Intra-operative time-registration and exposure of predefined anatomical structures were recorded.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: IFC-group
The investigators included patients undergoing laparoscopic cholecystectomy by a single surgeon between September and December 2013 at a single centre university department with unrestricted referral of patients. The included patients represented all patients undergoing laparoscopic cholecystectomy by one surgeon during the study period. All patients underwent intra-operative fluorescent cholangiography (IFC) with concomitant angiography, according to a standardized protocol, during their laparoscopic cholecystectomy.
Procedure: Intraoperative fluorescent cholangiography (IFC)
A standardized protocol with IFC including concomitant angiography was performed during laparoscopic cholecystectomy.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time expenditure of IFC with concomitant angiography.
Time Frame: Four months
Intra-operative fluorescent-imaging-mode-time was registered by a study-nurse during the operations (performed between september and december 2013)
Four months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Success-rate of the IFC-procedures.
Time Frame: Four months

The operating surgeon completed a structured questionnaire immediately after each operation regarding anatomical identification by IFC (visible cystic duct, -common bile duct, -common hepatic duct, -right and left hepatic ducts, -cystic artery, -aberrant bile ducts, and/or other abnormalities).

Successful IFC was defined as exposure of the junction between the cystic duct, common bile duct and common hepatic duct by IFC. Success-full fluorescent angiography was defined as adequate visualisation of the cystic artery within Calot´s triangle by the method.
Four months
