[Contribution of laparoscopy-biopsy to the diagnosis of primary liver neoplasms]

After a review of the literature, personal observations of primary benign and malignant tumours of the liver, studied using laparoscopic biopsy are presented and the importance of this examination in the early diagnosis of primary hepatic tumours is stressed. This examination, particularly when associated with biopsy, is very useful since it reduces diagnosis time with little or no risk to the patient with a high percentage of positive results.
