To overcome this matter, we have previously described a technical tip for preventing guidewire injury, termed \u2018liver impaction technique\u2019. However, its technical feasibility has been not reported in the setting of a large patient cohort. <\/jats:p><\/jats:sec><jats:sec><jats:title>Objectives:<\/jats:title><jats:p> The aim of study was to evaluate the clinical usefulness of the liver impaction technique during EUS-HGS. <\/jats:p><\/jats:sec><jats:sec><jats:title>Design:<\/jats:title><jats:p> Retrospective, single-center study. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p> This retrospective study included consecutive patients who underwent EUS-HGS between April 2018 and September 2022. The primary outcome of this study was the technical success rate of guidewire insertion using the liver impaction technique. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p> A total of 166 patients were enrolled in this study. Initial successful guidewire insertion without using liver impaction technique was obtained in 108 patients (65.1%). Among 58 patients in whom guidewire insertion failed initially, guidewire advancement into the periphery of the bile duct was observed in 32 patients (55.2%) and into a non-interest bile duct branch was observed in 26 patients (44.8%). Liver impaction technique contributed to increasing the technical success rate of guidewire insertion from 65.1% to 95.8%. Overall, adverse events were observed in 12 patients (7.2%; bile peritonitis n\u2009=\u20099, cholangitis n\u2009=\u20093), and these adverse events were Grade I. Among patients who underwent liver impaction technique ( n\u2009=\u200958), adverse events were observed in two patients (3.4%; bile peritonitis). Also, guidewire sharing was not observed in any patients during liver impaction technique. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p> In conclusion, the liver impaction technique may be helpful during EUS-HGS to obtain successful guidewire insertion into the biliary tract of interest.
