Long-term Outcomes After Emergency Laparotomy: a Retrospective Study

Abstract

Background: Emergency laparotomy (EL) is a common surgical operation with poor outcomes. Patients undergoing EL are often frail and have chronic comorbidities, but studies focused on the long-term outcomes after EL are lacking. The aim of the present study was to examine the long-term mortality after EL. Methods: We conducted a retrospective single-center cohort study of 674 adults undergoing midline EL between May 2015 and December 2017. The follow-up lasted until September 2020. The primary outcome was 2-year mortality after surgery. The secondary outcome was factors associated with mortality during follow-up. Results: A total of 554 (82%) patients survived > 90 days after EL and were included in the analysis. Of these patients, 120 (18%) died during the follow-up. The survivors were younger than the non-survivors (median [IQR] 64 [49–74] vs. 71 [63–80] years, p < 0.001). In a Cox regression model, death during follow-up was associated with longer duration of operation (OR 2.21 [95% CI 1.27–3.83]), higher ASA classification (OR 2.37 [1.15–4.88]), higher CCI score (OR 4.74 [3.15–7.14]), and postoperative medical complications (OR 1.61 [1.05–2.47]). Conclusions: Patient-related factors, such as higher ASA classification and CCI score, were the most remarkable factors associated with poor long-term outcome and mortality after EL.
