Purpose
Current guidelines advocate liberal use of delayed abdominal closure in patients with acute mesenteric ischemia (AMI) undergoing laparotomy. Few studies have systematically examined this practice. The goal of this study was to evaluate the effect of delayed abdominal closure on postoperative morbidity and mortality in patients with AMI.
Methods
We performed a retrospective cohort study of the ACS-NSQIP 2013–2017 registry. We included patients with a diagnosis of AMI undergoing emergency laparotomy. Patients were divided into two groups based on the type of abdominal closure: (1) delayed fascial closure (DFC) when no layers of the abdominal wall were closed and (2) immediate fascial closure (IFC) if deep layers or all layers of the abdominal wall were closed. Propensity score matching was performed based on comorbidities, pre-operative, and operative characteristics. Univariable analysis was performed on the matched sample.
Results
The propensity-matched cohort consisted of 1520 patients equally divided into the DFC and IFC groups. The median (IQR) age was 68 (59–77), and 836 (55.0%) were female. Compared to IFC, the DFC group showed increased in-hospital mortality (38.9% vs. 31.6%, p = 0.002), 30-day mortality (42.4% vs. 36.3%, p = 0.012), and increased risk of respiratory failure (59.5% vs. 31.2%, p < 0.001).
Conclusions
The delayed fascial closure technique was associated with increased mortality compared to immediate fascial closure. These findings do not support the blanket incorporation of delayed closure in mesenteric ischemia care or its previously advocated liberal use.
