Predictors of High-Output Stoma After Low Anterior Resection With Diverting Ileostomy for Rectal Cancer

Background: The aim of this study was to identify predictors of high-output stoma (HOS) after low anterior resection (LAR) with diverting ileostomy for rectal cancer. Methods: The medical records of 60 patients who underwent LAR with diverting ileostomy for rectal cancer between 2012 and 2015 were reviewed. HOS was defined as ileostomy output greater than 1500 mL per 24 hours. Patient and surgical characteristics and patient laboratory data were examined to assess for predictors of HOS using univariate and multivariate logistic regression. Results: The incidence of HOS was 43.3% (26/60). In univariate analysis, age ≥ 70 years, diabetes mellitus (DM), preoperative albumin level ≤ 4.0 g/dL, and preoperative serum hemoglobin level ≤ 12 g/dL were significantly associated with HOS. Multivariate analysis identified DM (odds ratio, 9.74; 95% confidence interval, 1.86–77.3) as an independent predictor of HOS. Conclusions: DM might be a predictor of HOS in patients undergoing LAR with diverting ileostomy for rectal cancer.
