    Abstract:
    BACKGROUND: Laparoscopy-assisted gastrectomy (LAG) is still limited for early gastric cancer (EGC) with low possibility of lymph node (LN) metastasis, due to the concern for incomplete LN dissection and controversial long-term outcomes. We assessed oncological outcomes of laparoscopy-assisted versus open gastrectomy (OG) for patients with LN positive EGC. METHODS: Between 2003 and 2007, 204 patients underwent surgery for LN positive EGC. We evaluated adequacy of LN dissection and early and long-term outcomes after OG (n = 162) and LAG (n = 42). RESULTS: Operative time was longer but hospital stay was shorter for LAG than OG. Postoperative complications occurred in 14 patients (8.6%) after OG and 1 patient (2.4%) after LAG (P = 0.316). Mean number of retrieved LNs and number of retrieved and metastatic LNs for each station did not differ between the two groups. During median 35 months of follow-up, 14 patients (8.6%) developed recurrence after OG, compared with 4 patients (9.5%) after LAG (P = 0.769). Overall 5-year disease-free survival was 89.9% and 89.7% after OG and LAG. Status of LN metastasis was the only independent prognostic factor for disease-free survival. CONCLUSIONS: LAG is an oncologically safe procedure even for LN positive EGC. Adequate LN dissection and comparable long-term outcomes to OG can be achieved by LAG.
