Less is more: time to expand the indications for minimally invasive video-assisted parathyroidectomy.

PURPOSE: Minimally invasive video-assisted parathyroidectomy (MIVAP) is one of the most widespread targeted parathyroid surgeries for primary hyperparathyroidism (PHP). The aim of this study was to assess its limits and propose an expansion of its indications in the management of parathyroid pathology. METHODS: A retrospective analysis of 77 consecutive patients who underwent MIVAP for PHP between Jan and Oct 2016 was conducted. The adequacy of the procedure and/or the need to convert to a standard cervicotomy was the main outcome of interest. Secondary outcomes of interest included: operative time, postoperative morbidity, postoperative pain assessed by the visual analogue scale (VAS) score, and the length of the surgical incision. RESULTS: There were 64 females and 13 males with a mean age of 51 years. In one patient a concomitant en bloc thyroid lobectomy was required due to features suspicious of parathyroid carcinoma while exploration was required in two other patients. None of these three cases required conversion to standard cervicotomy. The mean operative time, length of incision and VAS score was 31 min, 17 mm and 1.6, respectively. Biochemical cure was achieved in all patients, and no postoperative morbidities were reported. CONCLUSION: MIVAP offers the ability to perform a neck exploration and/or an en bloc thyroid lobectomy without the need to convert to a standard cervicotomy. Therefore, it not only serves as a targeted parathyroid procedure but also a potential alternative to full neck exploration.

Minimally invasive video-assisted thyroidectomy: reflections after more than 2400 cases performed.

BACKGROUND: The minimally invasive video-assisted approach was developed for primary hyperparathyroidism in 1997 and the year after for thyroid disease. Since then, the technique has been adopted worldwide, and indications moved from the initial benign disease to low-risk and intermediate-risk carcinoma, demonstrating a level of oncologic radicality comparable to the conventional open approach when inclusion criteria are strictly respected. METHODS: Between 1998 and 2014, 2412 minimally invasive video-assisted thyroidectomies (MIVAT) were performed in our department. The indication for surgery in 825 patients (34.3 %) was a malignant tumor, in particular, a papillary carcinoma in 800 patients. Among them, 528 patients operated on between 2000 and 2009 had a mean complete follow-up of 7.5 (standard deviation, 2.3) years. RESULTS: A total thyroidectomy was performed in 1788 patients (74.1 %) and a hemithyroidectomy in 564 (23.4 %). Also performed was central compartment lymphadenectomy in 31 patients (1.3 %) and parathyroidectomy for the presence of a solitary parathyroid adenoma in 29 (1.2 %). Mean duration of the procedure was 41 (standard deviation, 14) minutes. After a mean follow-up of 7. 5 years, 528 patients who underwent MIVAT for low-risk or intermediate-risk papillary carcinoma presented a cure rate of 85 % (undetectable thyroglobulin), comparable with the 80 % rate reported in patients who had undergone open thyroidectomy during the same period. CONCLUSIONS: After a long experience and a considerable number of procedures performed in a single center, MIVAT is confirmed as a safe operation, with a complication rate comparable with open thyroidectomy. MIVAT offers a cure rate for the treatment of low-risk and intermediate-risk malignancies that is comparable with an open procedure when inclusion criteria are strictly respected.
