Aim: To investigate factors related to poor dietary intake after gastrojejunal bypass surgery for unresectable malignant tumor.
Subjects and Methods: We retrospectively analyzed data of 40 patients who underwent gastrojejunal bypass surgery for unresectable malignant tumor between April 2007 and March 2016. Patients were divided into two groups by dietary intake. Logistic regression analysis was performed to determine independent risk factors for poor dietary intake. A p value less than 0.05 was considered statistically significant in univariate and multivariate analyses.
Results: The study population comprised 35 cases of gastric cancer and 5 cases of pancreatic cancer. Poor dietary intake was determined in 8 cases (20.0%). Univariate analysis revealed that a survival period ≤ 75 days (p=0.004), neutrophil/lymphocyte ratio (NLR) ≥ 6 (p=0.020), and Controlling Nutritional Status score ≥ 3 (p=0.037) were statistically significant factors associated with poor dietary intake. Multivariate logistic regression analysis revealed that poor dietary intake was associated with a survival period ≤ 75 days (OR: 28.8, 95%CI: 1.53-541.0), and that poor dietary intake had a marginally significant association with NLR ≥ 6 (OR: 14.6, 95%CI: 0.87-247.0).
Conclusion: Preoperative NLR is an important predictor of poor dietary intake after gastrojejunal bypass surgery for unresectable malignant tumor.
