271. Benigne Lebertumoren: Diagnostik und Therapie

Summary Of 537 patients with tumorous diseases of the liver, 187 had benign liver diseases. In this group (mean age 39 years) the female sex dominated by 2:1. Of the patients with focal nodular hyperplasia (FNH) or hepatocellular adenomas (HA) 80% had used oral contraceptives for more than 2 years, 70% for more than 5 years. Improved diagnostic methods (such as sequential scintigraphy, blood pooling, dynamic computer tomography, sonography and thin needle biopsy) enabled the correct classification of 87 of the tumors. Of 101 benign liver tumors (FNH, HA and hemangiomas), 41 were resected while 64 were observed for a longer time. Most (9 of 10) proven HAs were resected either by hemihepatectomy or by atypical resection. In 3 of these cases we diagnosed malignancy. We could not classify the tumor preoperatively in 12 of 38 cases of FNH.
