Introduction: Different minimally invasive techniques of parathyroidectomy have been described. We performed a retrospective study to evaluate the indications and results of video-assisted parathyroidectomy (VAP) in the management of patients with primary hyperparathyroidism (PHPT).
Materials and methods: Between 1998 and 2002, 528 patients were operated on because PHPT. VAP was proposed for patients with sporadic PHPT, without associated goiter and previous neck surgery, in whom a single adenoma was localized. VAP was performed by lateral approach with insufflation for patients with adenoma located deeply in the neck and by gasless midline approach for anteriorly located adenomas. A quick parathyroid (qPTH) assay was used during the surgical procedure. Calcemia, phosphoremia and PTH were systematically evaluated after surgery.
Result: Of 528 patients with PHPT, 228 (43%) were not eligible for VAP because associated nodular goiter (99 cases), previous neck surgery (42 cases), suspicion of multiglandular disease (25 cases), lack of preoperative localization (48 cases), and miscellaneous causes (14 cases). VAP was performed in 300 patients with sporadic PHPT : 282 lateral access, 17 midline access and one thoracoscopy. Mean operative time was 50’. Conversion to conventional parathyroidectomy was required in 14% of cases. One patient presented a definitive recurrent nerve palsy. One persistent and one recurrent PHPT were observed.
