[Liver tumors. Laparoscopic aspects].

A review is given on laparoscopic possibilities in the differentiation of tumours of the liver. Benign lesions are rare and usually discovered by chance. Primary cancer of the liver can be verified ante finem in a maximum of 40% of the cases. Characteristic is the endoscopic picture in the case of haemangiosarcoma after arsenic, Thorotrast, vinyl chloride (marked capsular fibrosis, net-like marking, "restless" surface of theliver). All the tumours need to be confirmed histologically. A tumour-like appearance is presented by echinococcus alveolaris and coarse-nodular granulomatous changes (sarcoidosis, lymphogranulomatosis, etc.).
