Indocyanine Green (ICG) fluorescence-guided surgery (I-FIGS) is increasingly being used in hepato-pancreatico-biliary (HPB) surgery. However, the true benefit of I-FIGS, the optimum dosing, and the timing of ICG administration still need to be determined. To conduct future research studies in the above areas, it is essential to understand the current I-FIGS practices among surgeons. This survey investigated the practices and perceptions of I-FIGS in liver surgery among HPB surgeons in the United Kingdom (UK). A survey was sent via email and social media to surgeons from all HPB units in the UK. The survey consisted of 18 questions, covering various aspects such as experience levels, volume of operations, approach to liver resections, ICG dosage, timing of administration, application specifics, camera systems used, and willingness to participate in future trials. The survey was sent to 81 HPB surgeons (working in 25 HPB units) across the UK. The response rate was 70% (57/81 surgeons). 56% of the surgeons reported having the infrastructure for I-FIGS at their hospital. The use of I-FIGS varied in duration and patient volume, with 47% of surgeons reporting its use for less than one year and 53% of surgeons reporting using it in fewer than ten patients. Preferences for the dose and timing of ICG administration also varied, reflecting the absence of standardised guidelines. The Storz camera system emerged as the most used imaging system (42% of surgeons), followed by the Stryker (25.8%). None of the surgeons reported any I-FIGS-related side effects. Ninety-six per cent of surgeons expressed interest in participating in future clinical trials in the field of I-FIGS. The survey highlights that I-FIGS in liver surgery is not widely used in the UK. There are also wide variations in the dosing and timing of ICG administration. Large multi-centre studies are needed to focus on dosing, timing of ICG administration, and establishing its actual role in liver surgery.
