Same day discharge after minimally invasive adrenalectomy: a national study.

BACKGROUND: Same day discharge (SDD) may be considered in some patients undergoing minimally invasive adrenalectomy (MIA). Recent studies have demonstrated similar outcomes between SDD and admitted patients; however, most excluded pheochromocytoma and adrenal metastases. This study evaluates 30-day complications and hospital readmission in a large cohort of patients undergoing MIA. METHODS: Adult patients undergoing MIA (2010-2020) for benign adrenal disorders, pheochromocytoma, and adrenal metastases were identified within the ACS-NSQIP database. Comparisons between patients having SDD versus admission were performed. Factors associated with 30-day complications and unplanned readmission were evaluated by multivariable regression modeling. RESULTS: Of 7316 patients who underwent MIA, 254 had SDD. Baseline characteristics were similar between groups, although SDD patients had lower ASA class (p < 0.001) and were more likely to undergo MIA for nonfunctioning adenoma or primary aldosteronism (p = 0.001). After adjusting for covariates, higher ASA class and presence of medical comorbidities were associated with increased complications (p < 0.001; p < 0.05) and unplanned readmission (p < 0.001; p < 0.05). Additionally, prolonged operative time was associated with 30-day complications (p < 0.001). Notably, SDD was not associated with increased complications (OR 0.78, 95% CI 0.38-1.61, p = 0.502) or unplanned readmission (OR 0.76, 95% CI 0.35-1.64, p = 0.490). The rate of SDD for MIA increased from 1.48% in 2017 to 10.81% in 2020. CONCLUSIONS: Not all patients undergoing MIA should have SDD; however, the current analysis demonstrates a trend toward SDD and supports its safety in select patients with adrenal metastases and benign adrenal disorders including pheochromocytoma.
