Clinical Report: Robotic Single-Port Subxiphoid Resection of Ectopic Parathyroid Adenomas
Overview
This case series reports the successful use of a robotic single-port subxiphoid approach for the resection of ectopic mediastinal parathyroid adenomas in two patients. The technique demonstrated safety, feasibility, and effective outcomes, including significant intraoperative decreases in parathyroid hormone levels.
Background
Ectopic mediastinal parathyroid adenomas are a rare yet significant cause of persistent primary hyperparathyroidism, often complicating surgical management due to their proximity to vital mediastinal structures. Traditional surgical approaches can lead to considerable morbidity, highlighting the need for minimally invasive techniques. The advent of robotic surgery, particularly the da Vinci Single-Port system, offers a promising alternative for these challenging cases.

Key Findings
100% success rate in robotic single-port subxiphoid excision with no conversions or intraoperative complications.
Mean operative time was 150 minutes, with minimal estimated blood loss (<50 mL).
Intraoperative PTH levels decreased by over 80% within 10 minutes post-excision in both patients.
Both patients achieved normalization of ionized calcium levels by one-week follow-up.
Final pathology confirmed parathyroid adenoma in both cases.
Clinical Implications
The findings support the use of a robotic single-port subxiphoid approach as a safe and effective method for resecting ectopic mediastinal parathyroid adenomas. This technique may reduce surgical morbidity and facilitate quicker recovery times for patients.
Conclusion
This case series highlights the potential of robotic single-port surgery as a minimally invasive alternative for the management of ectopic mediastinal parathyroid adenomas, warranting further investigation and application in clinical practice.
Turns out biology tracks more than we thought — from a spit test that reads your all-nighter to a surgical outcome that still shows up in household chores two decades later. Plus: habits aren't built gradually. They snap.
