Hartmann’s procedure is a treatment option for perforated acute diverticulitis, especially when organ dysfunction(s) are present. Its use has been criticized mostly out of fear of high permanent stoma rate. The aim of this study was to investigate the rate of stoma reversal, reasons behind nonreversal, and safety of reversal surgery. This was a single-center retrospective study of patients undergoing urgent Hartmann’s procedure due to acute diverticulitis between the years 2006 and 2017 with follow-up until March 2021. A total of 3,319 episodes of diverticulitis in 2,932 patients were screened. The Hartmann’s procedure was performed on 218 patients, of whom 157 (72%) had peritonitis (48 (22%) with organ dysfunction). At 2-years, 76 (34.9%) patients had died with stoma, 42 (19.3%) were alive with stoma, and 100 (45.9%) had undergone stoma reversal. The survival of patients with and without reversal were 100% and 42.7% at 1-year, 96.0% and 35.0% at 2-years and 88.9% and 20.7% at 5-years, respectively. The risk factors for nonreversal were old age, a need for outside assistance, low HElsinki Staging for Acute Diverticulitis stage, and higher C-reactive protein level upon hospital admission. The most common reasons for nonreversal in surviving patients were patient not willing to have the operation 18 (41%) and dementia 10 (23%). Twelve (12%) patients had a major complication after reversal (Clavien-Dindo IIIb–IV) and 90-day mortality after reversal was 0%. After the Hartmann’s procedure for acute diverticulitis, one-third died, half underwent stoma reversal, and one-fifth did not undergo stoma reversal within 2 years. Patients who survive with stoma are either not willing to have reversal or have severe comorbidities excluding elective surgery. The Hartmann’s procedure remains a viable option for high-risk patients with perforated acute diverticulitis. [Display omitted]
