AIM: To characterise training for, and conduct of, image-guided liver tumour ablation amongst UK interventional radiologists.
MATERIALS AND METHODS: A web-based survey of British Society of Interventional Radiology members was carried out between 31 August to 1 October 2022. Twenty-eight questions were designed, covering four domains: (1) respondent background, (2) training, (3) current practice, and (4) operator technique.
RESULTS: One hundred and six responses were received, with an 87% completion rate and an approximate response rate of 13% of society members. All UK regions were represented, with the majority from London (22/105, 21%). Seventy-two out of 98 (73%) were either extremely or very interested in learning about liver ablation during training, although levels of exposure varied widely, and 37/103 (36%) had no exposure. Performed numbers of cases also varied widely, between 1-10 cases and >100 cases per operator annually. All (53/53) used microwave energy, and most routinely used general anaesthesia (47/53, 89%). Most 33/53 (62%) did not have stereotactic navigation system, and 25/51(49%) always, 18/51 (35%) never, and 8/51(16%) sometimes gave contrast medium (mean 40, SD 32%) after procedures. Fusion software to judge ablation completeness was never used by 86% (43/55), sometimes used by 9% (5/55), and always used by 13% (7/55) of respondents.
CONCLUSION: Although there are high levels of interest in image-guided liver ablation amongst UK interventional radiologists, training arrangements, operator experience, and procedural technique vary widely. As image-guided liver ablation evolves, there is a growing need to standardise training and techniques, and develop the evidence base to ensure high-quality oncological outcomes.
