Radiology-guided percutaneous approach is superior to EUS for performing liver biopsies

We read with interest the study titled ‘Radiology-guided percutaneous approach is superior to EUS for performing liver biopsies’ by Bang et al .1 Authors conclude that radiology-guided percutaneous liver biopsy is superior based on comparing the proportion of optimal samples obtained, defined as a sample with length of ≥25 mm and complete portal tracts (CPTs) of ≥11. Further evaluation of the results in this study shows no significant difference between the two methods regarding the number of CPTs, but a significantly higher sample length in the percutaneous group. We propose that the results and the conclusions of the study are misleading and not generalisable to clinical practice. The main flaw of this study is the use of a suboptimal technique for performing the endoscopic ultrasound …
