Resection margin in laparoscopic hepatectomy: a comparative study between wedge resection and anatomic left lateral sectionectomy

Operative outcomes are similar between laparoscopic WR and LLS. However, WR is less reliable than LLS in achieving a resection margin of more than 1 cm. Larger studies involving more patients with longer follow-up are warranted to determine the impact of the resection margin on intra-hepatic recurrence and survival.
