Abstract
Endoscopic surgery for primary hyperparathyroidism (PHPT) started in 1996 with a parathyroidectomy performed by Michel Gagner. The technique we propose and have been using for 6 years is based on a unique central access and external retraction. From February 1997 to October 2003, 370 of 520 patients affected with PHPT (71%) underwent minimally invasive video-assisted parathyroidectomy (MIVAP). There were 72 men and 298 women, with a mean age of 55.8 years. Twenty-four patients (6.5%) of the 370 in this series underwent MIVAP under loco-regional anesthesia, and the others had general anesthesia. Eleven patients were lost to follow-up. Surgical cure of PHPT was achieved in 353 patients (98,3%), as confirmed by a median follow-up of 35.1 months (range: 2–82 months). Video-assisted exploration was successfully performed in 350 patients (94%). The mean operative time was 36.2 minutes. In 21 cases (5.6%) a concomitant procedure was performed: a thyroid lobectomy in 14 cases and a total thyroidectomy in 7 cases. Patients were generally discharged the day after surgery. Most of the patients (91%) were satisfied with the cosmetic result 6 or more months after the procedure. Complications developed in 14 cases: 10 cases (2.7%) of transient hypoparathyroidism 3 cases (0.8%) of definitive palsies of the recurrent nerve, and 1 case of postoperative bleeding (0.27%). After 6 years of experience, MIVAP appears to be as safe and curative as traditional surgery, with better cosmetic results and better postoperative outcome.
