Characteristics and Outcome Analysis for Intensive Care Patients Undergoing Decompressive Laparotomy for Abdominal Compartment Syndrome: Impact of Extracorporeal Membrane Oxygenation Support.

(1) Background: Abdominal compartment syndrome (ACS) is a life-threatening situation and is associated with high mortality in the intensive care unit (ICU). Decompressive laparotomy represents the last therapeutic option. This cohort study aims to optimize the selection of ICU patients suffering from ACS who benefit from decompressive laparotomy. (2) Methods: All available data from adult patients treated at the 12 ICUs of a university hospital between 2011 and 2019 were included. Outcome parameters for patients with and without extracorporeal membrane oxygenation (ECMO) were compared. (3) Results: 207 ICU patients with ACS undergoing surgery were identified. Laparotomy resulted in immediate improvement of organ functions in 15% of patients, who then survived more frequently. The overall mortality rate in our cohort was 69%. The group of ECMO patients-including va- and vv-ECMO-showed significantly less organ function improvement and a higher mortality rate of 79% compared to a better postoperative improvement and a lower mortality rate of 62% in non-ECMO patients. (4) Conclusions: There are ICU patients who benefit from decompressive laparotomy-nevertheless, mortality is high. Non-ECMO patients have a better prognosis than ECMO patients. Our findings can support clinical decision-making on emergency surgery and the development of future guidelines.
