- W4308485711 abstract "Malnutrition characterized by the involuntary loss of body weight and skeletal muscle can be the result of both aging and malignancy. As a result, geriatric patients could face an increased nutritional risk. This study aimed to investigate the nutritional and functional status of geriatric patients and their association with postoperative complications.Patients who underwent abdominal surgery for digestive cancer in our center between January 2020 and August 2021 were included in the study. Computed tomography scans were collected to evaluate muscle mass and density. Changes in body weight, muscle strength, physical performances, nutritional risk, and status were evaluated upon admission. Postoperative outcomes collected included postoperative length of stay, complications, and 30-d readmission.A total of 1513 patients were included for the analysis. Of these, 72.8% were at risk for malnutrition (70.3% in the non-geriatric group and 75.4% in the geriatric group; P = 0.031), and 28.9% had malnutrition according to the Subjective Global Assessment (26.0% in the non-geriatric group and 31.8% in the geriatric group; P = 0.016). Compared with younger patients, geriatric patients have decreased muscle mass (skeletal muscle index, 44.8 versus 47.4; P < 0.001) and skeletal muscle density. Significant weight loss and loss of skeletal muscle occurred concurrently in 18.8% of the patients and were more frequent in the geriatric group (22.3% versus 14.7%; P < 0.001). In multivariate analysis, an age of 65 y or older (odds ratio [OR], 1.41; 95% confidence interval [CI], 1.07-1.86; P = 0.014), a serum albumin level ≤4.11 g/dL (OR, 1.35; 95% CI, 1.03-1.77; P = 0.03), skeletal muscle loss (OR, 1.69; 95% CI, 1.28-2.24; P < 0.001), declined functional status (OR, 1.5; 95% CI, 1.14-1.98; P = 0.004), systematic inflammation (OR, 1.71; 95% CI, 1.09-2.8; P = 0.026), and significant weight loss (OR, 1.4; 95% CI, 1.06-2.85; P = 0.017) were independent predictors of overall postoperative complications. Although there was a trend of interactions between advanced age, skeletal muscle loss, and significant weight loss, multivariate analysis showed none of the interactions were significantly predictive of overall postoperative complications.Geriatric patients are at greater risk for malnutrition. Their declined nutritional and functional status together with advanced age could increase the risk for postoperative complications. Nutrition evaluation should be part of the preoperative workup, and timely interventions should be initiated if needed, especially in geriatric patients." @default.
