[Study on the application of laparoscopy-assisted radical gastrectomy for gastric cancer in the elderly].

Objective: To evaluate the feasibility and efficacy of laparoscopy-assisted D2 radical gastrectomy for elderly patients with gastric cancer.
Methods: From October 2007 to October 2012, 233 gastric cancer patients over 65 years underwent D2 lymph node dissection. Among them, 109 patients underwent laparoscopy-assisted radical gastrectomy(LAG group), while 124 patients underwent conventional open gastrectomy(OG group).
Results: Compared to the OG group, LAG group was associated with less bleeding [(102.5±34.3) ml vs. (181.7±73.8) ml, P<0.05], quicker postoperative recovery of bowel function[(2.8±0.6) d vs. (4.0±1.2) d, P<0.05], shorter postoperative length of hospital stay[(10.7±7.5) d vs.(14.2±6.5) d, P<0.05], longer operative time [(231.2±51.4) min vs. (208.5±53.6) min, P<0.05]. The postoperative complication rate of LAG group and OG group was 10.1%(11/109) and 21.0%(26/124) respectively(P<0.05). Short-term quality of life of LAG group was better than that of OG group(P<0.05). The 5-year survival rates were 54.5% and 59.2% in LAG and OG groups respectively, and there was no significant difference(P>0.05).
Conclusions: Efficacy of laparoscopy-assisted D2 radical gastrectomy is similar to open gastrectomy in elderly gastric cancer patients with less invasiveness.
