Endoscopic parathyroidectomy in primary hyperparathyroidism

Area of Science:

• Endocrinology
• Minimally Invasive Surgery
• Surgical Oncology

Background:

• Endoscopic video-assisted parathyroidectomy (EP) has become increasingly accepted for primary hyperparathyroidism (PHPT).
• The gasless endoscopic technique offers an attractive minimally invasive approach.
• Preoperative localization using ultrasonography and 99m Tc-Sestamibi scintigraphy is crucial for patient selection.

Purpose of the Study:

• To evaluate the surgical outcomes of endoscopic gasless parathyroidectomy (EP).
• To assess the efficacy of preoperative imaging in patient selection for EP.
• To determine the feasibility of introducing EP into general head and neck surgical practice.

Main Methods:

• A retrospective analysis of 75 patients with sporadic PHPT undergoing EP between 2005 and 2009.
• Patients were selected based on specific criteria, excluding significant goiter, prior neck surgery, need for thyroidectomy, obesity, and multiple enlarged glands.
• Preoperative localization utilized ultrasonography and 99m Tc-Sestamibi scintigraphy.

Main Results:

• 59 patients (78%) were candidates for EP; 77% had positive localization with 99m Tc-Sestamibi.
• Conversion to open surgery was required in 18% of cases.
• The procedure had a median operating time of 45 minutes, with no permanent hypocalcemia or recurrent laryngeal nerve palsy. 94% of patients had normal calcium and PTH levels at 3 months.

Conclusions:

• Endoscopic video-assisted parathyroidectomy (EP) is a quick, safe, and effective procedure for selected PHPT patients.
• Preoperative imaging plays a vital role in patient selection and surgical planning.
• EP can be readily integrated into standard head and neck surgical practices.
