Analysis of influencing factors on hospitalization time for mild ischemic colitis

Objective To analyze the factors influencing hospitalization duration in patients with ischemic colitis(IC). Methods A retrospective study was conducted on patients with mild IC of Tianyou Hospital affiliated to Wuhan University of Science and Technology from January 2017 to July 2024. Patients were categorized into two groups based on hospitalization duration (≤7 days and >7 days). Data on general characteristics, medical history, clinical manifestations at admission, initial laboratory test results, colonoscopy findings, and imaging examinations were collected for both groups. Factors with statistical significance in univariate analysis were included in multivariate Logistic regression analysis to identify risk factors influencing hospitalization duration. Results A total of 132 patients with mild IC were included in the study, with 60 patients in the ≤7 days group and 72 patients in the >7 days group. Univariate analysis showed statistically significant differences between the two groups in stroke, white blood cell count, neutrophils count, blood sodium level, blurred fat space on abdominal CT, and mesenteric artery stenosis detected by CTA (P<0.05). Multivariate Logistic regression analysis identified a history of stroke [OR=4.319, 95%CI (1.108, 16.837)], hyponatremia [OR=0.843, 95%CI (0.729, 0.976)], blurred fat space on abdominal CT [OR=4.392, 95%CI (1.308, 14.749)], and mesenteric artery stenosis detected by CTA [OR=3.882, 95%CI (1.273, 11.836)] as independent risk factors for hospitalization duration >7 days (P<0.05). Conclusion The hospitalization duration of patients with mild IC is influenced by multiple factors. A history of stroke, hyponatremia on initial laboratory tests, blurred fat space on abdominal CT, and mesenteric artery stenosis detected by CTA are closely associated with a hospitalization duration of more than 7 days.
