BACKGROUND/AIMS: Hepatic adenoma (HA) is a rare benign tumor of the liver. Tumor resection has been recommended for symptomatic or enlarging HA because of the risk of intraperitoneal, intrahepatic hemorrhage or even the development of hepatocellular carcinoma. From 1989 to 2003 we reviewed the medical records and radiology files of 28 patients with a proved diagnosis of hepatic adenoma. This article summarizes a single-center experience with surgical treatment of hepatic adenoma. METHODOLOGY: 24 patients were female and 4 were male. Twenty-two patients had a history of oral contraceptive use. Abdominal pain was presented in 19 patients and 3 of them had had an acute episode. The mean age was 36.3 years. Preoperative assessment included liver test, ultrasonography and computed tomography in all patients plus technetium (99mTc)-sulfur colloid and 99mTc-labeled DISIDA (dimethyliminoacetic acid) liver scintigraphy (n=19) and magnetic resonance imaging (n=22). RESULTS: Operative procedures included enucleation in 3 patients, two of them associated with hepatic segmentectomy; resection of one or two segments in 14 patients; left and right hemihepatectomy respectively in 7 and 3 patients; right extended hepatectomy in one patient and nonanatomic resection in one patient. There was no postoperative death and the complications were: bile leakage (re-operation) one patient, intraperitoneal abscess (re-operation) one patient, pleural effusion two patients, venous thrombosis one patient and wound infection one patient. CONCLUSIONS: We recommend that since the diagnosis has been well-established both enucleation or anatomically based resections of hepatic adenoma should be performed in all cases mainly in female patients taking oral contraceptives with tumors greater than 3cm for the risk of hepatic hemorrhage or even when malignancy cannot be excluded.
