A total of 916 patientswho underwent gastric cancersurgery at Samsung Medical Center between December 2009 and September 2011 were prospectively collected. We examined the occurrence of SSI (primary endpoint), assessments of wound healing (secondary endpoint). They were evaluated postoperatively on days 3, 7, and 30.
RESULTS:
Of the 916 patients, 122 were excluded postoperatively by screening (out of the study protocol, adverse events, etc.). The remaining 794 patients were enrolled and monitored postoperatively. The cumulative SSI incidence was 11 cases (1.39%; 95% confidence interval [CI], 0.77-2.50) on day 30. Seromas were most frequently detected in wound healing assessments, with a cumulative incidence of 147 cases (18.51%; 95% CI, 15.98-21.39) on day 30.
