    Definitive anatomopathological findings in thyroidectomized patients with preoperative diagnosis of follicular neoplasm
    (SOC CIRUJANOS CHILE, 2012) Goni E, Ignacio; Krstulovic R, Claudio; Leon R, Augusto; Gonzalez D, Hernan; Solar, Antonieta; Campusano M, Claudia; Ruiz A, Eu. Catalina
    Background: The finding of follicular neoplasm, using a FNAP, is an indication for partial or total thyroidectomy, to obtain the definitive malignant or benign histology. Frequently, it is possible to identify significant additional histological diagnosis. Aim: To obtain the definitive histological findings in patients with follicular neoplasm by FNAP. Patients and Method: Transversal analysis of 133 patients that underwent to total thyroidectomy between 2003 and 2009, that filled de requirements for adequate histological assessment. Results: In 33.1% of the treated patients the final diagnosis was indeed a follicular neoplasm (adenoma in 26.3% and cancer in 6.8%). In the 51.9% the finding was follicular colloidal hyperplasia and other thyroid cancer in 8.3%. The total malignant prevalence in the whole gland was 29.3%. Conclusions: The thyroidectomy is the treatment of choice and the final diagnostic procedure for these patients. The histological findings of cancer different from follicular not only in the punctioned nodule are a secondary and an additional argument for reinforcing the surgical indication.

    Postoperative thyroid bed granuloma incidence using ultrasonic knife in total thyroidectomy in cancer patients
    (SOC CIRUJANOS CHILE, 2012) Goni E, Ignacio; Krstulovic R, Claudio; Leon R, Augusto; Gonzalez D, Hernan; Cruz O, Francisco; Ruiz G, Eu Catalina
    Background: The postoperative thyroid bed granuloma incidence is high and it is an adittional difficulty for the ultrasound differential diagnosis of eventual local cancer recurrence. The ultrasonic knife utilization eventually can reduce the incidence of these granuloma when is compare with other traditional ligatures methods. Objective: to evaluate the postoperative thyroid bed granuloma incidence with the ultrasonic knife utilization, detected by ultrasound. Methods: retrospective study of 57 evaluable thyroidectomy performed for cancer between March and September 2010. In 46 patients were used traditional ligatures (silk or linen) and in 11, ultrasonic knife. Results: of the 57 patient included, 47 were females. The age average was 44 years old. Postoperative thyroid bed granuloma incidence was 36.3% (CI95%, 7.9%-64.7%) in the group where ultrasonic knife was used and 36.9% (IC95%, 23.0%-50.9%) in which traditional ligatures were used. No statistical difference was found (p = 0.974). Conclusions: The ultrasonic knife utilization had not reduced the postoperative thyroid bed granuloma incidence, when was compared with conventional ligatures. In this sense, this device is probably unable to add benefits for the differential diagnosis of thyroid cancer local recurrence.
