Objective To analyze the risk factors of recent postoperative complications in elderly patients with gastric cancer.

Methods The clinical data of 93 patients aged 80 years undergoing radical gastrectomy were retrospectively analyzed. According to the recent postoperative complications, the patients were divided into observation group and control group. The preoperative data, intraoperative data and postoperative data between the two groups were compared. The univariate analysis and multivariate logistic regression were used to analyze the risk factors of recent postoperative complications in elderly patients.

Results There were 27 cases of recent postoperative complications in all patients, accounting for 29.03% of the total. Univariate analysis results showed that preoperative body mass index (BMI), preoperative nutrition risk screening 2002 (NRS2002) score, whether combined with diabetes, whether combined chronic obstructive pulmonary disease, whether combined with organ resection, intraoperative bleeding volume, operation time were correlated with the occurrence of recent postoperative complications in elderly patients with gastric cancer (P ＜ 0.05 to P ＜ 0.01). Moreover, multivariate logistic analysis showed that preoperative BMI ≥ 25 kg/m², preoperative NRS2002 score ≥ 3, the history of chronic obstructive pulmonary disease, intraoperative bleeding volume ≥ 300ml were the independent risk factors of recent postoperative complications (P ＜ 0.05 to P ＜ 0.01).

Conclusion Preoperative BMI ≥ 25 kg/m², preoperative NRS2002 score ≥3, the history of chronic obstructive pulmonary disease, intraoperative bleeding volume ≥300ml are the high-risk factors for the occurrence of recent postoperative complications in elderly patients with gastric cancer.
