Comparative study of laparoscopic-assisted radical gastrectomy versus open radical gastrectomy for early gastric cancer / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate laparoscopic radical gastrectomy for early gastric cancer.</p><p><b>METHODS</b>A total of 204 patients with early gastric cancer undergoing laparoscopic-assisted radical gastrectomy or open radical gastrectomy between October 2004 and December 2009 were retrospectively reviewed and analyzed. Patients were divided into laparoscopic group(LAP, n=78) and open group (OPEN, n=126). Operative time, blood loss, time to passage of flatus, postoperative hospital stay, complications and pathologic findings were compared between the two groups.</p><p><b>RESULTS</b>Compared to the OPEN group, operative time in the LAP group was significantly shorter[(202.9±45.6) min vs.(219.8±45.2) min, P<0.05], blood loss was less[(144.5±146.5) ml vs. (245.0±146.4) ml, P<0.05], time to passage of flatus was shorter[(3.1±1.1) d vs.(4.5±1.6) d, P<0.05], postoperative hospital stay was shorter[(10.8±1.2) d vs. (12.4±3.8) d, P<0.05]. However, the two groups were comparable with regard to postoperative complication rate(10.3% vs. 12.7%, P>0.05), proximal resection margin[(4.0±1.9) cm vs. (4.2±1.7) cm, P>0.05], distal resection margin [(3.6±1.7) cm vs. (3.5±1.8) cm, P>0.05], number of harvested lymph node(13.1±6.5 vs. 14.5±8.2, P>0.05). The median follow up was 22(2-64) months. There were no tumor recurrences or metastases in the LAP group. In the OPEN group, only 1 patient died from peritoneal metastasis. Total hospital costs between the two groups were similar(P>0.05).</p><p><b>CONCLUSION</b>Laparoscopic radical gastrectomy is a safe, feasible, effective, and less invasive surgery for early gastric cancer.</p>
