Unilateral parathyroid exploration

Area of Science:

• Endocrinology
• Surgical Oncology
• Radiology

Background:

• Primary hyperparathyroidism is often caused by a single parathyroid adenoma.
• Surgical management aims for curative resection with minimal morbidity.
• Traditional bilateral neck exploration (BNE) is effective but can lead to longer operative times and increased complications.

Purpose of the Study:

• To evaluate the efficacy and safety of unilateral neck exploration (UNE) for primary hyperparathyroidism.
• To determine the accuracy of preoperative ultrasound (US) in guiding UNE.
• To compare operative outcomes between UNE and BNE.

Main Methods:

• Retrospective review of 106 patients with primary hyperparathyroidism operated on between May 1989 and October 1996.
• Preoperative ultrasound (US) was performed in 77 patients by a specialized radiologist.
• UNE was performed when US findings localized the pathology to one side and operative findings were consistent.

Main Results:

• Ultrasound accuracy for parathyroid localization was 90% when performed by an interested radiologist.
• Patients undergoing UNE had significantly shorter operative times (P = 0.001) compared to BNE.
• UNE demonstrated a significantly lower complication rate (22%) compared to BNE (45%, P = 0.04), primarily due to fewer cases of hypocalcemia.

Conclusions:

• Unilateral neck exploration (UNE) is a safe and effective surgical approach for primary hyperparathyroidism when guided by accurate preoperative ultrasound localization.
• UNE offers significant advantages over BNE, including reduced operative time, decreased morbidity, and avoidance of contralateral neck scarring.
• Accurate, noninvasive, and cost-effective preoperative localization studies, such as parathyroid US, are crucial for successful implementation of UNE.
