Objective To summarize the experience in the diagnosis and surgical treatment of hepatocellular adenoma(HCA).Methods A retrospective analysis was conducted on the clinical data of 7 patients with HCA who underwent surgical treatment at the Hepatobiliary Pancreatic Surgery Department of Zhejiang Provincial People's Hospital and the Tongde Hospital of Zhejiang Province from November 2008 to August 2020.Results all 7 patients were found by physical examination,with 4 males and 3 females.Age ranged from 27 to 59 years.Three patients had a body mass index(BMI)greater than 24,and 4 patients were within the normal range.All 7 cases were single lesions,and 2 cases of HCA were correctly diagnosed before surgery,accounting for only 28.6%.All patients underwent surgical treatment,with 6 undergoing laparoscopic hepatectomy and 1 undergoing open hepatectomy.Postoperative pathology confirmed HCA.Conclusion The preoperative diagnosis of HCA is difficult,and there are often no obvious clinical manifestations.Most of the time,physical examinations have found that for a single lesion with intact capsule,there are no signs of cirrhosis or tumor depletion,and AFP is normal.CT arterial phase shows significant enhancement.Patients with continuous enhancement in the portal vein phase or uneven enhancement in early MRI should be highly suspicious.Surgical treatment is safe and effective,Regular follow-up and re examination should be emphasized after surgery.
