    Abstract:
    AIM: Our aim was to investigate the predictive factors for Hartmann's reversal and to describe the differences in the rates and timings of Hartmann's reversal for various causative diseases. METHOD: In this multicentre retrospective cohort study patients who underwent Hartmann's procedure (HP) between 2006 and 2018 were enrolled. To describe the demographic patterns of Hartmann's reversal through to 2021, we analysed the cumulative incidence rate of Hartmann's reversal over time based on the Kaplan-Meier failure estimate. Multivariable Cox proportional hazard analysis was performed with cluster-adjusted robust standard errors to calculate hazard ratios (HRs) for the assessment of variables associated with colostomy reversal. RESULTS: Of 250 patients who underwent the index HP and survived to discharge, 112 (45%) underwent subsequent Hartmann's reversal (36% for malignant and 51% for benign disease). The causative diseases with the highest probability of colostomy reversal were trauma (85%) and diverticular disease (73%). Conversely, colostomy reversal was performed in only 16% for colonic volvulus and 17% for bowel ischaemia. Home discharge after index HP (HR 5.22, 95% CI 3.31-8.23) and a higher body mass index (HR 1.03, 95% CI 1.01-1.04) were associated with a higher probability of Hartmann's reversal, whereas older age, malignant disease and a history of cardiovascular and psychoneurological diseases were independently associated with a lower probability of colostomy reversal. CONCLUSION: The probability and timing of Hartmann's reversal varied considerably with the surgical indications for colostomy creation. Our results could help surgeons counsel patients and their families regarding stoma closure surgery to set realistic expectations.
