Abstract

BACKGROUND: Early readmission after discharge from the hospital is an undesirable outcome. Ileostomies are commonly used to prevent symptomatic anastomotic complications in colorectal resections. OBJECTIVE: The aim of this study was to identify factors predictive of readmission after colectomy/proctectomy and diverting loop ileostomy. DESIGN: This study is a retrospective review. PATIENTS: Patients were included who underwent colon and rectal resections with ileostomy at our institution. Sex, age, type of disease, comorbidities, elective vs urgent procedure, type of ileostomy, operative method, steroid use, ASA score, and the use of diuretics were evaluated as potential factors for readmission. MAIN OUTCOME MEASURES: The primary outcomes measured were the need for readmission and the presence of dehydration (ostomy output ≥1500 mL over 24 hours and a blood urea nitrogen/creatinine level =20, or physical findings of dehydration). RESULTS: Six hundred three loop ileostomies were created mostly in white (95.3%), male (55.6%) patients undergoing colon or rectal resections. IBD was the most common indication at 50.9%, with rectal cancer at 16.1%, and other at 31.0%. The 60-day readmission rate was 16.9% (n = 102) with the most common cause dehydration (n = 44, 43.1%). Regression analysis demonstrated that the laparoscopic approach (p = 0.02), lack of epidural anesthesia (p = 0.004), preoperative use of steroids (p = 0.04), and postoperative use of diuretics (p = 0.0001) were highly predictive for readmission. Furthermore, regression analysis for readmission for dehydration identified the use of postoperative diuretics as the sole risk factor (p = 0.0001). LIMITATIONS: This study is limited by the retrospective analysis of data, and it does not capture patients that were treated at home or in clinic. CONCLUSION: Readmission after colon or rectal resection with diverting loop ileostomy was high at 16.9%. Dehydration was the major cause for readmission. Patients receiving diuretics are at increased risk for readmission for dehydration. High-risk patients should be treated more cautiously as inpatients and closely monitored in the outpatient setting to help reduce dehydration and readmission.
