Factors affecting timing of loop ileostomy closure: a regional centre's experience with 106 patients

Abstract Introduction The burden of defunctioning ileostomy is significant with up to two thirds of patients reporting stoma‐related morbidity. While timely reversal is safe and cost‐effective, the time to reversal in regional Australian hospitals is not well described in professional publications. We aim to assess the current timeliness of ileostomy closure and identify possible reasons for delaying closure. Methods A retrospective analysis of loop ileostomies created and reversed in Launceston General Hospital for both rectal cancer surgery and other benign indications was undertaken. Patients with loop ileostomy created between 2010 and 2020 were included. Clinical data of timing of events, complications, readmission and stoma follow‐up were recorded; and analysed using multivariate regression analyses to identify clinically relevant risk factors for delayed closure. Results A total of 123 patients underwent loop‐ileostomy formation during the study period, of which 106 patients (86.2%) were reversed. Median time to closure was 8.5 months (IQR 5.2–12.4) for patients with rectal cancers, compared to 5.2 months (IQR 3.6–9.3) for patients who did not have rectal cancer, with a difference of 3.4 months (95% CI 0.9, 5.9; P = 0.008). Adjuvant chemotherapy and unexpected readmission to hospital were associated with delayed reversal ( P = 0.0081 and P = 0.0005, respectively). Conclusion Stoma reversal is often scheduled 3–6 months after creation. More than two‐thirds of patients experienced delays due to changing clinical concerns and non‐clinical factors, such as unexpected delays at each stage of surgical planning. Early placement on the waiting list and better‐coordinated follow‐ups may expedite reversal surgery and reduce associated morbidities.
