Impact of scalpel type on operative time and acute complications in thyroidectomies: [[pt]]Impacto do tipo de bisturi no tempo operatório e complicações agudas em tireoidectomias

Abstract Introduction Thyroidectomy is the most common surgery in the cervical region. Currently, several techniques are available for intraoperative hemostasis. Objective To compare the performance of three techniques (monopolar and bipolar electrical and ultrasonic) on operative time and postoperative complications. Methods Patients submitted to total thyroidectomy without prior treatment were included in this prospective series study, using a scientific design. Results A total of 834 patients were included; 661 women (79.3%) and 173 men (20.7%). The diagnosis was malignant neoplasia in 528 patients (63.3%) and benign disease in 306 patients (36.7%). The monopolar electric scalpel was used in 280 patients (33.6%), bipolar scalpel in 210 patients (25.2%) and ultrasonic scalpel in 344 patients (41.3%). The operative time was significantly shorter with the ultrasonic or bipolar scalpel when compared to the electric scalpel. In a linear regression model, gender, malignancy diagnosis and power energy type were significant for the procedure duration. Patients who underwent surgery with an ultrasound or bipolar scalpel had a significantly lower incidence of hypoparathyroidism. Conclusion The use of ultrasonic or bipolar scalpel significantly reduces operative time and the incidence of transient hypoparathyroidism.
