Early Outcome of Treatment of Chronic Mesenteric Ischemia.

Overview

There are limited data regarding long-term outcomes of chronic mesenteric ischemia (CMI) of the intestine. We sought to identify treatment outcomes of CMI. The NIS database was used to identify patients admitted for the diagnosis of CMI between 2002 and 2012. Multivariate analysis using logistic regression was performed to quantify outcomes of CMI. A total of 160,889 patients were admitted for chronic vascular insufficiency of intestine; of which 7,906 patients underwent surgical/endovascular treatment for CMI. Among patients who underwent surgery 62 per cent had endovascular treatment and 38 per cent had open vascular treatment. Need of open surgery (adjusted odds ratio (AOR): 5.13, P < 0.01) and age ≥70 years (AOR: 3.41, P < 0.01) had strong associations with mortality of patients. Open vascular treatment has higher mortality (AOR: 5.07, P < 0.01) and morbidity (AOR: 2.14, P < 0.01). However, endovascular treatment had higher risk of postoperative wound hematoma (AOR: 2.81, P < 0.01). Most patients admitted for CMI are treated with endovascular treatment. Endovascular treatment has the advantage of lower mortality and morbidity. Need to open surgery and age ≥70 years have strong associations with mortality of patients.
