Ischemic colitis: risk factors, diagnosis and prognosis in patients undergoing surgery

摘要

Objective: To identify risk factors, diagnosis and prognosis associated with ischemic colitis, focusing mainly on patients undergoing surgery. Materials and methods: This retrospective study included all patients admitted to the Centro Hospitalar de S?￡o Jo?￡o - E. P. E., diagnosed with ischemic colitis during the period from 2012 to 2013. Results: The study included 154 patients; 118 were undergoing medical treatment, with a 12% mortality rate, and 36 were undergoing surgery, with a 61% associated mortality rate. Hypertension was the most common risk factor in both groups. The presence of a large num- ber of cardiovascular risk factors in both groups, such as hypertension and dyslipidemia, was recorded, but we still found no direct relationship with development of ischemic coli- tis. Comorbidities that affect blood flow, such as the presence of thrombi or aneurysms, do provide a worse prognosis and therefore require a more aggressive treatment. Conclusion: The diagnosis of ischemic colitis is not always immediately established due to a nonspecific presentation. Surgical treatment should be reserved for severe cases with a worse prognosis associated.
