Objective To determine the effectiveness and outcomes of minimally invasive parathyroidectomy. Design Prospective, non‐randomised, non‐blinded trial. Setting Affiliated university teaching hospitals of the Northern Clinical School, University of Sydney, New South Wales, May 1998 to October 1999, Patients 50 consecutive patients who underwent minimally invasive parathyroidectomy for primary hyperparathyroidism, and 150 consecutive patients undergoing open parathyroidectomy over the same period. Results Minimally invasive parathyroidectomy was successfully completed and resulted in cure (normocalcaemia) in 42 of 50 patients (84%). Seven patients (14%) required conversion to an open procedure, all of which also resulted in normocalcaemia, giving an overall cure rate of 98%. One patient had persistent hyperparathyroidism after minimally invasive parathyroidectomy which was cured at subsequent open reoperation. Three patients had a temporary recurrent laryngeal nerve palsy. Open parathyroidectomy was successful in 147 of 150 patients (98%) at initial operation; one patient had a temporary recurrent laryngeal nerve palsy. Intraoperative measurement of parathyroid hormone levels by a quick technique in 23 of the patients (13 having minimally invasive and 10 open procedures) correctly identified the presence of multiple‐gland disease. Conclusion Minimally invasive parathyroidectomy is a feasible procedure, although there are concerns about the complication rate.
