Abstract
Background
Laparoscopy-assisted gastrectomy (LAG) has gained acceptance as one of the best treatments for early gastric cancer. However, the application of LAG with D2 lymph node dissection in patients with locally advanced gastric cancer (AGC) remains controversial.
Methods
We launched a prospective randomized controlled trial comparing laparoscopic and open gastrectomy with D2 lymph node dissection for locally AGC to evaluate technical safety and oncologic feasibility. The postoperative morbidity and mortality rates were based on the modified intention-to-treat analysis.
Results
Between January 2010 and June 2012, a total of 328 patients with preoperative clinical stage T2–3N0–3M0 gastric cancer were enrolled in the trial. Six patients with unresected AGC were excluded, and the remaining 322 patients were randomized to the laparoscopic group (162 patients) or the open group (160 patients) for radical surgery. All patients underwent D2 lymph node dissection including 18 (5.59%) proximal gastrectomies, 196 (60.87%) distal gastrectomies, and 108 (33.54%) total gastrectomies. Six patients (3.70%) in the LAG group were converted to open procedures. The overall complication rate was 11.72% in the LAG group and 14.38% in the open group (P = 0.512). No mortality occurred in either group.
Conclusions
The short-term results of the current study suggest that LAG with D2 lymph node dissection is a safe and feasible procedure in treating patients with locally AGC in experienced centers.
