Abstract
Minimally invasive video-assisted total thyroidectomy (MIVATT) is a treating option for small thyroids that demands skills required for both traditional thyroidectomy and endoscopic surgery. This prospective study aims to define the learning curve for MIVATT for residents, with experience in traditional thyroid and laparoscopic surgery. In all, 36 MIVATTs for benign disease were evenly divided among 4 residents. We recorded and analyzed: age, sex, pathology, thyroid weight, duration of the operation, ΔCa (postoperative minus preoperative calcemia), ΔWBC (postoperative minus preoperative white blood cell count), vocal motility, operative difficulty, postoperative vocal alteration, postoperative pain, complications, gram of gland excised per minute of the operation, conversion, and hospitalization. Statistically significant differences were observed in the different learning points, between duration of surgery (p < .001), operative difficulty (p = .022), grams of gland excised per minute of operation (p < .001), and WBC (p = .011). Surgeons that are experience in both thyroid and endoscopic surgery are subjects to a short learning curve concerning MIVATT.
