%X OBJECTIVE: This study aimed to determine which comorbidities were associated with intractable epistaxis requiring electrocauterization or embolization, and to identify the location where intractable epistaxis frequently occurred.
METHODS: The patients were divided into two groups: patients with epistaxis successfully controlled in outpatient department (OPD) and those with intractable epistaxis in OPD which was controlled by surgical exploration or arterial embolization (OP/EM). Evaluations of the bleeding locations, related vessels, and patient's comorbidities were conducted.
RESULTS: A total of 41 patients from the OP/EM group and 725 patients from the OPD group were enrolled. The following comorbidities showed elevated risks of the intractable epistaxis (p< 0.05) in multivariate analysis; hypertension (OR 1.089, 95% CI 1.049 - 1.132), dyslipidemia (1.132, 1.041 - 1.232), liver cirrhosis (1.272, 1.152 - 1.406), chronic obstructive pulmonary disease (1.234, 1.078 - 1.412) and asthma (1.205, 1.053 - 1.379). Inferior and middle turbinate were equally the most common location of the intractable bleeding.
CONCLUSIONS: In patients with epistaxis requiring hemostatic treatments, comorbidities such as hypertension, dyslipidemia, liver diseases, COPD, and asthma were associated with intractable epistaxis. The main bleeding sites of intractable epistaxis were the middle and inferior turbinate.
