A real-world study evaluating ultrasound-guided percutaneous non-targeted liver biopsy needle failures and pathology sample-quality assessment in both end-cut and side-notch needles.

Objectives: To determine biopsy device failures, causative factors, complications and sample quality of the 16G end-cut Biopince and side-notch Bard needles.

Methods: All ultrasound-guided non-targeted liver biopsies between 01/01/2016 and 31/12/2018 were included. Operator, device, number of failures, complications and repeat biopsies were recorded.
