BACKGROUND/AIMS: We divided overall complications after surgical resection for gastric cancer into fatal and non-fatal, and examined them in view of risk factors. Next we examined the meaning of dividing complications into two groups. METHODOLOGY: Records of 331 patients who underwent gastrectomies for cancer between 1992 and 2003 were used. Any postoperative overall complications were divided into fatal and non-fatal according to the association with mortality. RESULTS: Leakage and respiratory complication were defined as fatal complications. Tumor size (cm) (OR=1.14, 95% CI 1.05-1.25, p=0.003) and patient age (OR=1.06, 95% CI 1.06-1.10, p=0.007) were shown to be risk factors for fatal complications. Total gastrectomy (vs. distal gastrectomy) was a risk factor for non-fatal complications (OR= 1.63, 95% CI 0.99-2.7, p=0.05). Extended lymphadenectomy was a further possible risk factor for non-fatal complications (OR=1.71, 95% CI 0.98-3.0, p=0.06). On the other hand, intra-operative blood loss (mL) was only a risk factor for overall complications (OR=1.001, 95% CI 1.0-1.001, p=0.009). CONCLUSIONS: Independent risk factors for fatal complications and those for non-fatal complications did not include that for overall complications. To divide overall complications into fatal or non-fatal was useful for finding the real reason for complications. We could not prepare preventive measures for complications until analyzing the divided groups.
