  Purpose

The investigators hypothesize that the da Vinci Fluorescence Imaging Vision System provides real-time endoscopic near infrared fluorescence imaging of the biliary anatomy as defined as identifying biliary vessels; either cystic duct, common hepatic duct (CHD) or common bile duct (CBD). Irradiation given to the patient during a classic cholangiography can be reduced.

Further study details as provided by Intuitive Surgical:

Primary Outcome Measures:
  • To identify biliary anatomy will be demonstrated by successful detection (90%) of one or more of the following biliary vessels: Cystic duct, common hepatic duct (CHD) or common bile duct (CBD). [ Time Frame: intra-operatively ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • observe and report peri-operative safety outcomes, including but not limited to incidence of adverse events and allergic reactions (rare according to the current knowledge and applications) [ Time Frame: within 2 weeks post-operatively ] [ Designated as safety issue: Yes ]

Enrollment: 72
Study Start Date: July 2011
Study Completion Date: December 2012
Primary Completion Date: December 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: ICG
Patient will received IV injection of ICG intra-operatively. Surgeon will view bile ducts under fluorescence imaging mode to see if ICG helps to identify biliary ducts.
Drug: Indocyanine green (ICG)
2.5mg indocyanine green (ICG) will be administerly (IV injection) 30 minutes before surgery

Detailed Description:

Up to 40 patients will be prospectively enrolled in this multi-centre (up to 5 centres) single arm study. After given consent, patients will undergo minimally invasive cholecystectomy with da Vinci Fluorescence Imaging using Indocynine green (ICG) and near infra-red light (NIR) to identify the surgically relevant anatomy of the biliary tree during this procedure.

Efficacy endpoints The efficacy of the da Vinci Fluorescence Imaging Vision System to identify biliary anatomy will be demonstrated by successful detection (90%) of one or more of the following biliary vessels: Cystic duct, common hepatic duct (CHD) or common bile duct (CBD).

Safety endpoints To observe and report peri-operative safety outcomes, including but not limited to incidence of adverse events and allergic reactions (rare according to the current knowledge and applications). Safety endpoints will be met by affirming the safety profile of the procedure, compared to currently available literature.
