SAT-LB40 Adrenalectomy - A Rural Teaching Hospital Experience

Background: Studies characterize the surgical managements of adrenal tumors are not common in rural hospitals. Methods: A retrospective study conducted at a single rural teaching hospital with subjects including 37 patients who had laparoscopic or open adrenalectomy between 2011 and 2017. Baseline characteristics and postoperative outcomes of patients were examined using univariate and multivariate methods. Logistic regression models were used to analyze perioperative complications. Truncated negative binomial regression models was used to analyze hospital length of stay. Pathologic distribution, correlation of pre-op and pathologic diagnoses were also analyzed.Results: On average, five adrenalectomies per year were done for primary adrenal pathology. Adrenocortical adenoma and pheochromocytoma were the two most common pathologic diagnoses. Length of stay increased in patients with open surgery, RR 3.78 (1.60-8.91), and malignancy, RR 3.18 (1.43-7.06), based on multivariate analysis. Factors associated with post-operative complications in univariable analysis are tumor size odds ratio (OR) 1.02 (95% confidence interval 1.00 to 1.05), and open surgery, OR 4.29 (0.96-21.52). This significance was not present at the multivariable analysis. Conclusions: Evaluation and surgical management of adrenal tumors in a rural hospital for seven years were characterized. The results of this study will contribute to future epidemiological research on adrenal incidentalomas and surgical managements of adrenal tumors in rural hospitals.
