Incisionless fluorescent cholangiography (IFC): a pilot survey of surgeons on procedural familiarity, practices, and perceptions

摘要

Background Incisionless fluorescent cholangiography (IFC) has recently been proven feasible, safe, and efficacious as an intraoperative procedure to help identify extrahepatic bile ducts during laparoscopic cholecystectomies (LC). We conducted a pilot survey of 51 surgeons attending an international conference who perform endoscopic cholecystectomies to identify their typical LC practices, and perceptions of IFC. Methods An international panel of ten IFC experts, all with > 500 prior IFC procedures and related research publications, convened during the 4th International Congress of Fluorescence-Guided Surgery in Boca Raton, Florida in February 2017. The panel was charged with developing questions about LC practices and experience with IFC, and perceptions regarding its advantages, barriers to use, and indications. These questions then were asked to other congress attendees during one of the didactic sessions using an online polling application. Attendees, who ranged from zero to considerable experience performing IFC, accessed the survey via their portable devices. Results Of the 51 survey participants, 51% were from North America; 77% identified themselves as general/minimally invasive surgeons, and roughly 60% performed under 50 cholecystectomies/year. Only 12% performed routine intraoperative cholangiography (IOC), while 72.3% routinely performed critical safety reviews. Thirty-five percent estimated that their institution's laparoscopic-to-open surgery conversion rate was > 1% during LC. Roughly 95% of respondents felt that surgeons should have access to a noninvasive method for evaluating extrahepatic biliary structures; 84% felt that the most advantageous characteristic of IFC is the lack of any biliary-tree incision; and 93.3% felt that IFC would have considerable educational value in surgical training programs; and 78% felt that any surgeon who performs LC could benefit. Conclusions Surgeons who participated in our survey overwhelmingly recommended the routine use of IFC during laparoscopic cholecystectomy as a complimentary imaging technique. Prospective randomized clinical trials remain necessary to determine whether IFC reduces the incidence of bile duct injuries and other LC complications.
