Objective  To summarize clinical features, imaging findings, diagnosis, treatment, and prognosis of patients with hepatic focal nodular hyperplasia. Method  The clinical data of patients with hepatic focal nodular hyperplasia who underwent hepatectomy from July 2014 to July 2016 in the Xiangya Hospital of Central South University were analyzed retrospectively. Results  There were 12 males and 19 females in the 31 patients with hepatic focal nodular hyperplasia, the male-to-female ratio was 1∶1.58. The age was from 15 to 67 years old with (39.7±11.5) years old. Physical examination found 21 cases, there were symptoms in 10 cases. Laboratory examination: only 2 patients with long-term drinking history had mild AST abnormality, HBsAgs of 6 cases were positive, CA19-9 level of one patient was slightly increased (40.54 kU/L). Thirteen patients with hepatic focal nodular hyperplasia were diagnosed by imaging examination, the diagnostic rate of MRI was significantly higher than that of color Doppler ultrasound (P<0.05) or CT (P<0.05). The diameter of the lesions ranged from 2 cm to 11 cm with (4.6±2.1) cm. All lesions were resected, including 13 cases by laparoscopic hepatectomy, and 18 cases by laparotomy. Compared with by the laparotomy, the intraoperative blood loss was less (P<0.05), the hospital stay and intestinal exhaust time were shorter (P<0.05) by the laparoscopic hepatectomy. Twenty-nine patients were followed up from 3 to 24 months, no patient died, the quality of life was better, no recurrence and metastasis happened. Conclusions  Hepatic focal nodular hyperplasia is benign lesion, it has a good prognosis, generally without clinical symptoms, its laboratory feature has no abnormality. The combination of multiple imagings and pathological diagnosis could improve diagnosis rate. Surgical resection should be performed for suspected malignant tumor or other hepatic occupying lesions. Laparoscopic surgery has some advantages of quick recovery and less bleeding for it.
