Outpatient adrenalectomy has the potential to decrease costs, improve inpatient capacity, and decrease patient exposure to hospital-acquired conditions. Still, the practice has yet to be widely adopted and current studies demonstrating the safety of outpatient adrenalectomy are limited by sample size, extensive exclusion criteria, and no comparison to inpatient cases. We aimed to study the characteristics and safety of outpatient adrenalectomy using the largest such sample to date across 2 academic medical centers and 3 minimally invasive approaches. All minimally invasive adrenalectomies were identified, starting from the time outpatient adrenalectomy was initiated at each institution. Cases involving removal of other organs, bilateral adrenalectomies, and cases in which a patient was admitted to the hospital before the day of surgery were excluded. Patient, tumor, and case characteristics were compared between outpatient and inpatient cases, and multivariable regression analysis was used to assess odds of 30-day readmission and/or complication. Of 203 patients undergoing minimally invasive adrenalectomy, 49% (n = 99) were performed on an outpatient basis. Outpatient disposition was more likely in the setting of lower estimated blood loss, case completion before 3 pm, and for surgery performed in the setting of nodule/mass and primary hyperaldosteronism versus Cushing’s syndrome, pheochromocytoma, and metastasis (P < .05). There were no significant differences in patient age, body mass index, American Society of Anesthesiologists class, procedure performed, or total time under anesthesia between inpatient and outpatient cases. On adjusted analysis, outpatient adrenalectomy was not associated with increased 30-day readmission rate (odds ratio 0.23 [confidence interval 0.04–1.26] P = .09) or 30-day complication rate (odds ratio 0.21 [confidence interval 0.06–0.81] P = .02). Outpatient adrenalectomy can be performed safely without increased risk of 30-day complications or readmission in appropriately selected candidates.
