Parathyroidectomy remains the only definitive cure for primary hyperparathyroidism (PHPT). In rare cases, ectopic hyperfunctioning glands are located in the mediastinum, necessitating a thoracic surgical approach. The objective of this project was to review a single high-volume institutional experience of this presentation, with specific attention to the use of a robotic-assisted thoracic surgery (RATS) approach. This was a single-center, 5-year retrospective cohort study. All patients who underwent RATS mediastinal mass resection (MMR) for PHPT at the University of Colorado Anschutz Medical Campus were targeted for inclusion. Patient cases were reviewed for demographics, history, operative data, laboratory values, and postoperative course. Eight patients underwent RATS-MMR for PHPT between 2018-2023. Median [interquartile range] operative time was 178 [138-213] minutes, and length of stay was 2.0 [1.5-2.0] days. One patient experienced post-operative chylothorax requiring dietary modification. There were no other 30-day complications or readmissions. Final pathology confirmed intrathymic parathyroid tissue in all patients. All patients achieved cure of PHPT. The robotic-assisted approach has low morbidity and associated hospital length of stay and can be safely used to cure PHPT. As this is a rare pathology with an infrequently utilized surgical approach, it is important to critically discuss the diagnostic evaluation and operative course, aimed at educating the thoracic surgeon who may encounter and assist in the management of these patients.
