The role of minimally invasive liver surgery to treat hepatic benign disease

Benign liver disease is extremely frequent and often asymptomatic. During the recent years, the widespread use of radiological imaging, in particular the use of abdominal ultrasound, has significantly increased the incidence of benign liver lesions incidental diagnosis (1-3). Incidental diagnosis of a benign liver lesion by abdominal ultrasound usually occurs in asymptomatic patients or in patients with other symptoms not related with the presence of the hepatic benign nodule.
