Diagnosis and surgical treatment of hepatocellular adenoma / 中华普通外科杂志

ABSTRACT

ObjectiveTo summarize our experience on the diagnosis and surgical treatment of hepatocellular adenoma (HCA).MethodsClinical data of 47 HCA cases managed from 1989 to 2009 were analyzed retrospectively. ResultsAll were single lesions.Preoperative correct diagnosis was established in only 7 cases ( 14.9％ ).Tentative malignant space-occupying lesions was diagnosed in other 40 cases (85.1％),including hepatocellular carcinoma in 11 cases,liver hemangioma in 10 cases,liver focal nodular hyperplasia in 14 cases and miscellaneous in the remaining 5 cases.Local resection,segmental hepatectomy,hepatic lobectomy and hemiheptectomy were performed according to the size and location of the lesions.To prevent recurrence or malignant transformation,not less than 1.0 cm safe margin was allowed in all cases.Final diagnosis was made by fast frozen pathology or postoperative pathology.Postoperatively 45 cases were followed up to 6 years without recurrence.ConclusionsPreoperative misdiagnosis of HCA is common.Surgical resection is the only effective treatment,and the prognosis of HCA is favorable.
