In the authors' group of 976 umaimed liver biopsies (ULB) 10 complications were recorded. The authors described them and compared them with reports from the world literature. Two patients from the group died after ULB. One as a result of biopsy from haemoperitoneum, the other patient died with delirium tremens after surgery called for by persisting peritoneal syndrome. In eight patients mild complications were involved. In five patients complications receded spontaneously, in three after administration of an analgetic. From the submitted paper ensues that ULB is not quite safe, even when used by an experienced physician and when all contraindications are respected. A smooth course is not ensured by a risk-free diagnosis, previous uncomplicated biopsies normal prebioptic haemocoagulation tests. It is essential to realize this with regard to every patient where we indicate ULB. It is better to omit it unless we are unequivocally convinced of its asset. The question thus is: What will be the benefit of ULB for the patient?
