[Is liver biopsy in gallbladder operations still indicated?].

Biopsy of the liver with the Tru-cut needle was done as a routine diagnostic procedure during gallbladder surgery in 166 cases. The data of history, ultrasonography and laboratory were compared with the microscopic liver findings. Preoperatively in 89% of the cases there was an indication for liver biopsy. In 11% of the cases, where there was no indication for preoperative biopsy, we found severe changes in liver histology. Therefore we recommend liver biopsy during gallbladder surgery as a routine procedure.
