title: Feasibility and safety comparison of laparoscopy-assisted versus open gastrectomy for advanced gastric carcinoma with D2 lymphadenectomy.
abstract: OBJECTIVE
  Laparoscopy-assisted gastrectomy for advanced gastric cancer still remains controversial. The aim of this study is to compare oncologic feasibility and technical safety of laparoscopic versus open gastrectomy for advanced gastric cancer with D2 lymphadenectomy by comparing patients' short-term postoperative outcomes.
  
  
  METHODS
  One hundred and one patients with laparoscopy-assisted gastrectomy and 101 patients with open gastrectomy were one-to-one matched and then compared in terms of operative outcomes and hospital courses.
  
  
  RESULTS
  The laparoscopic group showed significantly longer operating time (297.4 vs. 198.1 min, P < 0.001), earlier first flatus time (2.8 vs. 3.6 days, P < 0.001), earlier diet start time (3.8 vs. 4.6 days, P < 0.001), shorter hospital stay (10.5 vs. 11.9 days, P < 0.001) and less morbidity (21.8 vs. 37.6%, P = 0.019). However, retrieval lymph nodes, intraoperative blood loss, transfused patients, postoperative fever and mortality were similar in the two groups. As for complications, incision infection (1.0 vs. 8.9%, P = 0.021) was significantly more common in the open group than in the laparoscopic group. In the subgroup comparisons of outcomes of laparoscopy-assisted gastrectomy, the tumor, node, metastasis III group showed significantly increased retrieval lymph nodes (37.2 vs. 31.0, P < 0.001), increased intraoperative blood loss (147.2 vs. 120.5 ml, P = 0.010), increased length of hospital stay (11.1 vs. 9.9 days, P < 0.001) and increased morbidity (32.6 vs. 13.8%, P = 0.024) when compared with the tumor, node, metastasis II group.
  
  
  CONCLUSIONS
  Laparoscopy-assisted gastrectomy is feasible and safe for the treatment of advanced gastric cancer with D2 lymphadenectomy compared with open gastrectomy. Higher-level tumor stage (tumor, node, metastasis III) may increase the operative risk and should be performed with caution by surgeons with considerable experience of laparoscopic gastrectomy.
