Background/Aims:
Laparoscopy-assisted gastrectomy is still controversial because of scant evidence of safety and feasibility. The objective of this study was to assess the feasibility of using the laparoscopy-assisted gastrectomy in treating gastric cancer and evaluate its outcome compared with conventional open gastrectomy.
Methodology:
Between November 2005 and November 2007, 31 patients underwent laparoscopy-assisted gastrectomy and 95 patients underwent open gastrectomy for gastric cancer. Clinicopathological characteristics, total number of lymph nodes retrieved and overall survival were retrospectively compared between the two groups.
Results:
No significant differences were found in the total number of retrieved lymph nodes (26.3±11.6 vs. 27.6±10.4) between the two groups. The mean follow-up and overall survival time after surgery was 30.8 (range 4-47) months and 40.9 months (95% confidence interval, 38.5-43.2 months), respectively. The mean survival time in patients of the laparoscopy-assisted gastrectomy group was 42.4 months vs. 40.3 months in patients of the open surgery alone group (p=0.457). A logistic regression model revealed that node invasion (hazard ratio 1.149, p<0.001) and serosal invasion (hazard ratio 4.623, p=0.044) were associated with overall survival of gastric cancer patients.
Conclusions:
Laparoscopy-assisted gastrectomy with D2 lymph node dissection is a safe and feasible procedure with adequate lymphadenectomy for the treatment of gastric cancer.
