To describe the results of an experimental study in the canine model in with us performed the realization of minimally invasive video-assisted thyroidectomy. METHODS: In 36 mixed healthy no parasitic dogs’ which were selected from the biotherius of the surgery experimental Institute of Medicine Faculty of Venezuelan Central University, without any selection criteria’s underwent to a thyroidectomy minimal assisted invasive between the years 2005 to 2007. The procedure was realized without CO2 insufflations, and it is carried out through a 15 mm central incision above the sternal notch. The dissection was performed under an endoscopic vision, using conventional and endoscopic instruments of Paolo Miccoli. RESULTS: We performed 18 lobotomies (right 11, left 7) and 16 total thyroidectomies. The mean operative time was 71.6 ± 3.2 minutes for lobotomy and 97.3 ± 5 minutes for total thyroidectomy. In the total thyroidectomies there was an appreciable bleeding (100 mL) in one case for venous lesion for the utilization of defector trocar. The conversion to open procedure was required in 2 %. We observed 2 cases of transient postoperative hipocalcemy and in one case of transient cord vocal palsy. The cosmetic result was considered excellent. CONCLUSIONS: The minimally invasive video-assisted thyroidectomy is safe and feasible in the experimental model. The clinical indications are limited at presented to specialized reference centers, but the results are encouraging, and we are optimistic about the future expansion of its applicability.
