We had 4 intraoperative hemorrhagic incidents, all in the first 15 cases and imputable to lack of expertise and improper usage of the device. The types of surgery performed were 4 hemithyroidectomies and 46 total thyroidectomies, 2 in association with unilateral functional neck dissections. The thyroid conditions for which surgery was indicated were: diffuse toxic goiter in 8 patients multinodular toxic and nontoxic goiter in 30 patients autonomous nodule in 2 patients 2 patients with benign nodules at fine needle aspiration biopsy (FNAB) 4 patients with nodules positive for carcinoma at FNAB, among them 2 with unilateral cervical lymph nodes enlargement 4 patients with highly suspect nodule on FNAB. The paper presents the initial experience of 50 cases with this device of a surgical team with special interest in endocrine surgery, mostly thyroid and parathyroid. In this respect, the advent of the ultrasonic surgical device Harmonic Focus Curved Shears (HFCS) from Ethicon Endo-Surgery constituted a major progress in the domain by its multiple capabilities of dissection, grasping, vessel sealing and transecting. Precise and safe hemostasis is necessary for successful thyroid surgery.
