Surgery or Endovascular Treatment, which is the Better Way to Treat Acute and Chronic Mesenteric Ischemia: Systematic Review and Meta-Analysis

1. Abstract
1.1. Objective: To investigate the influence of surgical and endovascular treatment on the prognosis of acute and chronic mesenteric ischemia and to further evaluate whether endovascular treatment can reduce postoperative complications by performing a meta-analysis.
1.2. Methods: We carried out a systematic literature search in three databases (PubMed, Embase, and Web of Science). All studies examining outcomes for patients undergoing endovascular intervention and open revascularization interventions for mesenteric ischemia were included.
1.3. Results: We summarized the available evidence from 25 studies with a total of 30,775 cases. The pooled results indicated that surgical intervention increases 30-day mortality (OR 1.45; 95% CI 1.08–1.95) and the incidence of postoperative pulmonary complications (OR: 1.61; 95% CI 1.28–2.04). However, this result seems to fit only in the subgroup with a large number of patients included.
1.4. Conclusion: The present study demonstrates that open surgery methods may increase the 30-day mortality in acute and chronic mesenteric ischemia and the incidence of postoperative pulmonary complications.
