Introduction: Hartmann’s procedure is a commonly performed general surgical operation. Although potentially reversible, recent evidence on reversal rates in the Australian literature is limited. The purpose of this study was to evaluate the proportion of patients undergoing Hartmann’s procedure that eventually proceed to reversal; and reasons for non-reversal. Methods: A single-centre retrospective study of all patients who underwent Hartmann’s procedure between January 2018 and December 2022 was performed, with patient follow-up until the end of July 2024. Medical records were reviewed to obtain clinical, operative, pathological and postoperative course details. Results: Two hundred and eighty-two patients underwent Hartmann’s procedure during the study period, of which 249 cases (88.3%) were performed in the emergency setting. The most common indications for Hartmann’s procedure were complications of sigmoid diverticulitis (53.5%), followed by malignancy (26.6%). One hundred and eleven patients (39.4%) proceeded to Hartmann’s reversal, with a median time interval of 405.5 days between initial Hartmann’s procedure and reversal (range 109-1392 days). Among the 171 patients who did not undergo reversal, 58 (33.9%) died during the follow-up period, including 22 (12.9%) with locally advanced or metastatic colorectal cancer. Thirty-four patients (19.9%) declined reversal. Conclusion: Hartmann’s procedure is performed predominantly in the emergency setting. Approximately 40% of patients underwent Hartmann’s reversal during the study period. Patient preference accounted for approximately 20% of non-reversal cases, which was an unexpected finding.
