Predictive Factors Affecting the Clinical Course of Patients With Diverticulitis: Who Needs Hospital Management?

ABSTRACT

PURPOSE: The aim of this study is to determine the predictable factors that affect the clinical course, especially the hospital stay, the operation performed, and to determine factors that will be helpful in deciding whether in-hospital or outpatient treatment is appropriate. METHODS: We retrospectively collected medical data for patients who had been diagnosed with acute diverticulitis at Inje University Sanggye Paik Hospital between January and December 2016. In total, 117 patients were enrolled in this study. We examined clinical factors, including age, sex, body mass index, pain, body temperature, white blood cell count, C-reactive protein, nil per os (NPO) time, hospital duration, computed tomography (CT) findings, location of diverticulitis, operation performed, and presence of comorbidity (e.g., hypertension and diabetes mellitus). RESULTS: In the multivariate analysis, the statistically significant factor related with hospital duration was the presence of perforation on the CT scan (P 7) (P = 0.011). Operations were mainly performed in patients with left-sided colonic diverticulitis (P = 0.012). CONCLUSION: We suggest a perforation finding on the CT scan, a severe pain score at least above 7 on a numeric rating pain scale, and a left-sided lesion are absolute indications for in-hospital management.
