Background: The aim of this study was to investigate the surgical and oncologic outcomes of laparoscopy-assisted gastrectomy (LAG) and open gastrectomy (OG) for advanced gastric cancer (AGC) using the case-control method with a sufficient follow-up period.
Patients and methods: The authors retrospectively analyzed 89 patients who underwent LAG and 345 patients who underwent OG for AGC between August 1999 and June 2007. A total of 176 matched cases were included in the final analysis.
Results: Except for tumor size and reconstruction, there were no statistically significant differences in the clinicopathological parameters between the two groups. Although operation time was significantly longer for LAG than OG (228.3 vs. 183.6 min, p < 0.0001), first flatus time and postoperative hospital stay without complications were significantly shorter in the LAG group (3.2 vs. 3.7 days, p < 0.0001; 7.0 vs. 10.4 days, p < 0.0001, respectively). Operation-related complications occurred in 7 cases (8.0%) in both groups. 13 patients (14.8%) in the LAG group and 15 patients (17.1%) in the OG group had recurrence. There was no statistically significant difference in the 5-year and disease-free survival rates between LAG and OG.
Conclusions: LAG for AGC might be considered to be a minimally invasive surgery in some selected cases, although a well-designed prospective study comparing LAG with OG for AGC is needed.
