    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.

    Recurrence of differentiated thyroid carcinoma without concomitant elevation of serum thyroglobulin. Report of two cases
    (2007) Velasco L, Soledad; Solar G, Antonieta; Cruz O, Francisco; Quintana F, Juan Carlos; Leon R, Augusto; Mosso G, Lorena; Fardella B., Carlos; NCD Risk Factor Collaboration (NCD-RisC)
    Thyroid carcinoma is the most prevalent endocrine tumor. and the papillary carcinoma (PC) is the most common histological type. In the follow-up, after tbyroidectomy serum thyroglobulin (s-Tg) is used as a marker to evaluate recurrence of thyroid carcinoma. In most cases, this parameter allows an adequate diagnosis,. but occasionally s-Tg may miss the detection of a recurrence. We report a 57 year old female and a 36,year old male sujected to a total thyroidectomy for a papillary thyroid carcinoma with intermediate and high-risk of recurrence. Both bad a cervical recurrence without a concomitant increase in s-Tg levels. In both, Tg staining was positive in the tumor cells. These cases confirm that in these patients, the follow-up must be done with measurement of s-Tg and complementary diagnostic tests.

    Ultrasound guided needle biopsy of the spleen. Review of 13 procedures
    (2010) Besa C, Cecilia; Teuber S, Cristobal; Huete G, Alvaro; O'Brien S, Andres; Cruz O, Francisco; Oyanedel Q, Roberto
    Background: Needle biopsies of the spleen were avoided due to the fear of bleeding in a highly vascularized organ. However their safety, even using 18 gauge needles, has been demonstrated. Aim: To report the experience with ultrasound guided needle biopsies of the spleen. Material and Methods: Retrospective review of records of ultrasound guided biopsies of the spleen using Tru-cut™ needles, performed between 2005 and 2009. Results: Thirteen procedures performed in 12 patients were identified. A specific diagnosis was achieved in nine (69%) procedures (lymphoma in four, melanoma in 2, sarcoma in 1, extremedullary erythropoiesis in one and splenic cryptococcosis in one. Two patients with negative results were subjected to a new biopsy, which yielded the diagnosis of lymphoma. A third patient was studied elsewhere, finding a malignant tumor. Two patients had complications, one had a vagal reaction and other had a perisplenic hematoma without clinical repercussion. Conclusions: Ultrasound guided needle biopsy of the spleen is a safe and useful procedure.
