Introduction:
Minimally Invasive Parathyroidectomy (MIP) has become the treatment of choice of Primary Hyperparathyroidism (PHPT) caused by an adenoma. In the present investigation we describe our experience with MIP performed under local anesthesia.
Methods:
MIP was performed on 454 of 496 patients (91.5%) with PHPT. In 170 patients (37.4%), MIP was accomplished under local anesthesia. This procedure was elected when the medical condition prohibited general anesthesia, or in accordance with the patient's request.
Results:
MIP under local anesthesia for PHPT was accomplished in 162 (95.3%) of the patients. In 8 patients the procedure was converted to general anesthesia, while the adenoma was located in 5 of these patients. In 3 patients (1.8%) the adenoma was not located even under general anesthesia and they awaited further investigations. Fifteen patients (8.2%) developed temporary hoarseness, and 20 patients (11.8%) developed temporary hypocalcemia postoperatively.
Conclusions:
MIP under local anesthesia for PHPT caused by an adenoma is feasible and safe, with a success rate of 95.3% similar to MIP performed under general anesthesia. MIP under local anesthesia has not yet become a prevalent procedure worldwide, as well as in our country. The results of the present study support our conclusions for utilizing this method under local anesthesia.
