Laparoscopic gastric cancer surgery: Current evidence and future perspectives

Abstract

Laparoscopicgastrectomy has been widely accepted as a standard alternative for the treatment of early-stagegastricadenocarcinoma because of its favorable short-term outcomes. Although controversies exist, such as establishing clear indications, proper preoperative staging, and oncologic safety, experienced surgeons and institutions have applied this approach, along with various types of function-preservingsurgery, for the treatment of advancedgastric cancer. With technical advancement and the advent of state-of-the-art instruments, indications forlaparoscopicgastrectomy are expected to expand as far as locally advancedgastric cancer.Laparoscopicgastrectomy appears to be promising; however, scientificevidencenecessary to generalize this approach to a standard treatment for all relevant patients and care providers remains to be gathered. Several multicenter, prospective randomized trials in high-incidence countries are ongoing, and results from these trials will highlight the short- and long-term outcomes of the approach. In this review, we describe up-to-date findings and critical issues regardinglaparoscopicgastrectomy forgastric cancer.
