title: Laparoscopic hepatectomy: indications and outcomes.
abstract: We outline the indications, evaluate the degree of invasiveness, and analyze the outcomes of laparoscopic hepatectomy, mainly in the treatment of hepatocellular carcinoma (HCC). The important considerations in determining indications for laparoscopic hepatectomy include tumor size, type, and location. Nodular tumors smaller than 4 cm or pedunculated tumors smaller than 6 cm are suitable candidates. Concerning location, tumors in the lower segment or the left lateral segment are suitable. Regarding operative method, laparoscopic hepatectomy involving either partial hepatectomy or left lateral segmentectomy is a feasible, less invasive procedure. Operative time in our recent laparoscopic hepatectomy patients has decreased, with less bleeding. Furthermore, laparoscopic hepatectomy is less invasive than conventional hepatectomy on evaluation by the Estimation of Physiolic Ability and Surgical Stress (E-PASS) scoring system. Patients recovered more quickly after laparoscopic hepatectomy, which allowed shorter hospitalization. Both the 5-year survival rate for HCC and the survival rate without recurrence were nearly identical to those of open conventional hepatectomy, although further analysis will be necessary to reach definitive conclusions. In conclusion, laparoscopic hepatectomy avoids the disadvantages of standard hepatectomy in properly selected patients and is beneficial for patient quality of life, because it is a minimally invasive procedure when indications are strictly followed.
