Validation of a score chart to predict the risk of chronic mesenteric ischemia and development of an updated score chart.

ABSTRACT: Background and objective:The objective of this article is to externally validate and update a recently published score chart for chronic mesenteric ischemia (CMI). Methods:A multicenter prospective cohort analysis was conducted of 666 CMI-suspected patients referred to two Dutch specialized CMI centers. Multidisciplinary consultation resulted in expert-based consensus diagnosis after which CMI consensus patients were treated. A definitive diagnosis of CMI was established if successful treatment resulted in durable symptom relief. The absolute CMI risk was calculated and discriminative ability of the original chart was assessed by the c-statistic in the validation cohort. Thereafter the original score chart was updated based on the performance in the combined original and validation cohort
