Abstract:

Objective: The objective of this study was to evaluate the utility of portable gamma-camera at real time intraoperative imaging for assessing localization of parathyroid adenoma.
Materials and Methods: This was a retrospective analysis of patients with parathyroid adenoma and oncologic underlying condition, such as breast cancer, renal, prostate, cervix, ovarian, and melanoma; who underwent radio guided surgery at Instituto Nacional de Cancérologie (INCan, México). Planar scintigraphy was performed 15 minutes after intravenous injection of 99mTc-MIBI, 60-120 min before intervention. The portable gamma-camera was used to identify the adenoma during surgery, as well as to verify if it was removed completely. All surgical specimens were taken for intraoperative histopathological evaluation.
Results: 20 patients were diagnosed with parathyroid adenoma (17 with usual location and 3 with ectopic location). Parathyroid adenoma was localized Intraoperatively with a portable gammacamera in all patients, reducing the time of surgery. All surgical specimens were confirmed as parathyroid adenoma in the intraoperative and definitive histopathological evaluation.
Conclusion: Parathyroid scintigraphy with portable gamma-camera in intraoperative identification of parathyroid adenoma has contributed to the development of minimally invasive parathyroidectomy. Therefore, in our opinion, in addition to the realization of preoperative scintigraphy, radio guided surgery with portable gamma-camera should always be performed, thus reducing complications, hospital stay, surgical and recovery time, with the same therapeutic effectiveness as classical treatment.
