Outpatient or short-stay thyroid and parathyroid surgery is still uncommon in Germany. Although a substantial number of these operations are performed with low morbidity, nearly zero mortality, and short operation time, some potentially lethal complications, especially postoperative hemorrhage, are strong arguments against liberal shortening of hospital stay. Symptomatic hematomas after thyroid and parathyroid surgery are observed in about 1-2% of cases. They frequently occur during the first 8 h after operation (40%). However, two thirds of these major complications occur later, about 20% of them more than 24 h postoperatively. Therefore, an outpatient procedure cannot be generally recommended. Short-stay (<23 h, overnight) thyroid and parathyroid surgery may be attractive, but this concept requires clear release-criteria and professional outpatient structures. Compared to general anesthesia, local and regional anesthesia did not emerge as helpful to shorten hospital stay. Also, prophylactic calcium supplementation is not recommended to enhance early hospital discharge after bilateral thyroid or parathyroid surgery.
