Outline of research　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　

"Purpose": Identify risk factors for preoperative and intraoperative complications in older patients with gastric cancer.

"Method": We analyzed the risk factors of infectious complications based on the Clavien-Dindo classification in 504 patients aged 65 and over who performed radical gastric resection were analyzed by statistical modeling and cross-checking methods from preoperative and during surgery.

"Results": Of the 504 patients, 95 (18.8%) had infectious complications. Analysis of preoperative factors alone showed that men, low prognostic nutritional index values, high visceral fat area, and total gastric resection is a risk of complications after gastrectomy. Among all intraoperative factors, long-term surgery with low prognostic nutritional index values were identified as risk factors for complications after gastomectomy. Furthermore, we found that the incidence of complications varies from group to group when patients are divided into five groups according to the number of positive risk factors for preoperative infectious complications.

"Conclusions": We found that older patients with gastric cancer need to carefully consider the indication of gastric resection and reduce complications if there are more preoperative risk factors before surgery.
