Background: /Objective: Laparoscopic distal gastrectomy for early gastric cancer is described as a treatment option in general practice. However, the oncological efficacy and technical safety of laparoscopic gastrectomy with D2 lymphadenectomy in locally advanced gastric cancer are controversial, and clinical trials are ongoing. This study aimed to evaluate the short-term and surgical outcomes between laparoscopic and open gastrectomy procedures in locally advanced gastric cancer.
Methods: We retrospectively analyzed data from 134 patients who underwent subtotal D2 gastrectomy for locally advanced gastric cancer in our hospital between January 2011 and December 2018. Clinicopathological characteristics, surgical outcome, postoperative recovery, disease-free survival, and overall survival were compared between those who underwent laparoscopic and open gastrectomies.
Results: Baseline characteristics were similar between patients who underwent open and laparoscopic surgeries. Less surgical time (250.8 vs. 347.6 min in laparoscopic vs. open surgery, respectively; P < 0.05) and lower blood loss (83.7 vs. 333 mL in laparoscopic vs. open surgery, respectively; P < 0.05) were noted in patients who underwent laparoscopic surgery than in those who underwent open gastrectomy. The time of starting oral intake was earlier and the length of postoperative hospital stay was shorter in the laparoscopic group than in the open group. Surgical morbidity and mortality rates, as well as disease-free survival and overall survival rates, did not differ between the two groups.
Conclusion: Laparoscopic gastrectomy is feasible and safe for locally advanced gastric cancer. Based on the perioperative results and short-term outcomes, laparoscopic gastrectomy is non-inferior to open gastrectomy.
