Minimally invasive video-assisted parathyroidectomy. Initial experience in a General Surgery Department.
BACKGROUND
The aim of this study is to analyze our preliminary results from minimally invasive video-assisted parathyroidectomy (MIVAP) and demonstrate the feasibility of MIVAP also in non-referral centers.


METHODS
During a period from June 2005 to January 2008, in the General Surgery Department of University of Trieste, we operated on 39 patients with primary hyperparathyroidism (pHPT). MIVAP by an anterior approach was proposed for 23 (59%) patients with sporadic pHPT and one unequivocally enlarged parathyroid gland on pre-operative ultrasound and 99mTc-SestaMIBI scintigraphy without associated goiter and without previous neck surgery. Intra-operatively, a quick parathyroid assay was used during the last 11 surgical procedures. All patients underwent pre-operative and post-operative investigations of calcemia, phoshoremia and PTH levels and vocal cord function. Age, operative times, pathologic findings, post-operative pain, calcemia, length of hospital stay, cosmetic results, and complications were retrospectively analyzed.


RESULTS
MIVAP was successfully accomplished in 22 cases. Conversion to standard cervicotomy was required in one patient (4.34%). Mean operative time was 67 min. Post-operative complications included 1 (4.34%) transient hypocalcemia. No laryngeal nerve palsies, no definitive hypocalcemias, no persistent pHPT and no recurrent pHPT were observed. The cosmetic result was excellent in all cases.


CONCLUSIONS
Our preliminary results demonstrate that MIVAP for localized single-gland adenoma, after adequate training, seems to be feasible with significant advantages, especially in terms of cosmetic results, post-operative pain, and post-operative recovery even in a General Surgery Department, if performed by a dedicated team, with a sufficient and specific activity volume.
