Purpose/Background: Diverting loop ileostomy is performed after colectomy to allow for anastomotic healing, and prevention of pelvic sepsis when anastomotic leak occurs. There is no consensus on the optimal timing of ileostomy closure, and there is limited data on complications associated with ileostomy closure greater than 12 months after creation. The aim of this study is to investigate outcomes of delayed loop ileostomy closure greater than 12 months after creation.Methods/Interventions: Patients undergoing loop ileostomy closure between 2013 and 2023 at Carilion Medical Center, in Roanoke, VA were reviewed. Cohorts compared were defined as Standard group (closure < 4 months) and Delayed group (closure > 12 months). Demographics and outcomes were compared. Statistical comparisons were performed using either Wilcoxon rank sum test, Pearson’s Chi-squared test or Fisher’s exact test.Results/Outcomes: There were 135 patients in the Standard group and 19 patients in the Delayed group. Demographics were similar between the groups except for a higher percentage of patients with diabetes, renal failure and history of cancer in Delayed group (all p < 0.05; Table 1). Operative time was longer for Delayed loop ileostomy closure (p < 0.05). Patients in the Delayed group were more likely to develop postoperative enterocutaneous fistula and demonstrated a higher hospital readmission rate within 30 days (p < 0.05). Both groups had similar return of bowel function on post-operative day 2, similar length of stay, and similar rates of postoperative ileus (p=NS; Table 2).Conclusion/

Discussion: Delayed loop ileostomy closure more than 12 months after creation does not delay return of bowel function, but may lead to higher hospital readmission rates within 30 days."Table 1: Comparing demographics of patient undergoing diverting loop ileostomy reversal
