ABSTRACT
Objective To investigate the feasibility and safety of minimally-invasive video-assisted parathyroidectomy ( MIVAP) for parathyroid adenoma ( PA) . Methods Clinical data of 14 patients with primary hyperparathyroidism ( PHPT) caused by PA between April 2011 and September 2014 in our hospital were analyzed retrospectively.Coexistent thyroid lesions were found in 6 patients.With preoperative definite diagnosis and localization, we performed parathyroidectomy and local excision or lobectomy of the thyroid gland.All the patients were confirmed by intra-operative fast frozen section pathological examination and postoperative pathological immunohistochemistry.Intra-and post-operative parathyroid hormone monitoring was conducted.Hoarseness, choking cough, and active bleeding were observed. Results All the procedures were accomplished successfully, without intra-operative abnormal blood loss or conversion to conventional operation.The operative time was 35-60 min ( mean, 50 min);the intra-operative blood loss was 1.7-32.0 g (mean, 9.75 g).Neither transient nor everlasting injury to recurrent laryngeal nerve or superior laryngeal nerve happened.No hemorrhage was observed.All the patients were followed up for 2-43 months ( mean, 16 months) , during which there was no recurrence. Conclusion MIVAP with thyroidectomy is feasible and safe for PA and coexistent benign thyroid lesions, on the basis of pre-operative adequate diagnosis and proper localization and intra-operative parathyroid hormone monitoring.
