Summary
Thoracoscopic excision of mediastinal parathyroid tumors is effective. Combining 99mTc-MIBI scintigraphy with radioisotope navigation further improves tumor identification and reduces surgery time for hyperparathyroidism patients.
Area of Science:
- Endocrinology
- Minimally Invasive Surgery
- Nuclear Medicine
Background:
- Ectopic mediastinal parathyroid adenomas/hyperplasia occur in hyperparathyroidism.
- Conventional open surgery has been the standard treatment.
- Advancements in diagnostic imaging enable better lesion localization.
Purpose of the Study:
- To evaluate the efficacy of thoracoscopic excision for mediastinal parathyroid tumors.
- To assess the benefits of integrating radioisotope navigation in the procedure.
Main Methods:
- Thoracoscopic surgery using a lateral approach with 3-4 trocars.
- Tumor identification and excision guided by preoperative diagnostic imaging, including 99mTc-methoxyisobutylisonitrile (MIBI) scintigraphy.
- Radioisotope-navigated thoracoscopic excision in the most recent case.
Main Results:
- Successful excision in four consecutive patients with short surgery times (50-140 min) and minimal blood loss.
- No intra- or postoperative complications observed; patients experienced uneventful recovery with minimal analgesia requirements.
- Radioisotope navigation halved tumor identification time, reducing overall surgery duration and patient stress.
Conclusions:
- Thoracoscopic excision is a favorable treatment for mediastinal parathyroid tumors.
- 99mTc-MIBI scintigraphy and radioisotope navigation enhance surgical precision and efficiency.
- Minimally invasive thoracoscopic approaches reduce patient morbidity and recovery time.
