Abstract

Background Ileostomy creation is associated with postoperative dehydration and readmission; however, the effect on renal function is unknown. Our goal was to characterize the impact of ileostomy creation on acute and chronic renal function. Materials and methods A retrospective cohort study with patients undergoing colorectal cancer surgery at a tertiary referral institution (2005-2011). The relationship between ileostomy creation and acute kidney injury (AKI)-related readmission, severe chronic kidney disease (CKD) at 12 mo (glomerular filtration rate <30 mL/min/1.73 m2), and onset of severe CKD over time was evaluated using multivariable logistic and Cox regression and adjusted using propensity score stratification. Results Among 619 patients, 84 (13%) had ileostomy. AKI-related readmission and severe CKD at 12 mo were more common among ileostomy patients (17% versus 2%, P < 0.01 and 13.3% versus 5%, P = 0.02, respectively). After propensity score adjustment, ileostomy was a significant predictor of AKI-related readmissions (odds ratio: 10.3; 95% confidence interval [CI], 3.9-27.2), severe CKD at 12 mo (odds ratio: 4.1; 95% CI, 1.4-11.9), and onset of severe CKD over time (hazard ratio: 4.2; 95% CI, 2.3-6.6). Conclusions Ileostomy creation is associated with increased risk of AKI-related readmissions and development of severe CKD. Future studies must focus on strategies to minimize kidney injury when ileostomy is a necessary component of colorectal cancer surgery and revisiting current indications for ileostomy creation.
