Introduction The presence of lymph nodes metastasis in papillary thyroid cancer (PTC) modifies the type of surgical resection as well as the indication of the treatment with I¹³¹ in the postoperative period. This therapeutic approach is based on the results of the diagnostic tests, like the cervical ultrasonography. Currently other methods of diagn...

Purpose: To study the dependency of the effective half-life on the administered activity and the correlation between the time-integrated activity and the remnant uptake at 2d and 7d in patients treated for DTC with 1.11 GBq, 3.7 GBq or 5.55 GBq of 131I-NaI. Methods: Ninety-two patients undergoing total thyroidectomy and lymph node removal were i...

Resumen Introducción La biopsia selectiva del ganglio centinela (BSGC) puede completar el estudio preoperatorio detectando adenopatías no visibles ecográficamente. De este modo, se puede estadificar a los pacientes y estratificar el riesgo de recidiva de forma más precisa y, por tanto, ayudar a definir el tipo de tratamiento tanto quirúrgico como...

Purpose: To analyse the activity uptakes, effective half-lives and time-integrated activities, of relevance for remnant dosimetry, for patients treated for papillary thyroid cancer (PTC) with a different amount of activity of 131I-NaI. Methods: Fifty patients were included. Of those, 18 patients had low-risk PTC and were treated with 1.11 GBq of...

Introduction The BRAF V600E mutation in papillary thyroid cancer (PTC) has been associated with resistance to ¹³¹I. Our aim was to quantify the response to ¹³¹I after surgery in patients who had the mutation (BRAF+) and those who did not have the mutated gene (BRAF−). Method A prospective cohort study was designed, from September 2015 to February...

To analyze the diagnostic accuracy of ultrasound-guided core-needle biopsy (CNB) of thyroid nodules. Of 3517 CNBs performed using an 18G spring-loaded device in one institution, we retrospectively reviewed 676 nodules in 629 consecutive patients who underwent surgery. CNB and pathological examination were compared. CNB diagnosis was standardized in...

The clinical significance and potential morbidity of PTMC is discussed. Particularly the differences between those PTMC identified postoperatively in histological examination (incidentals), and those diagnosed preoperatively (non-incidentals). We retrospectively analyzed differences in clinical presentation and course after treatment in these two g...

Bochdaleck hernia is a type of congenital hernia due to the persistence of the pleuroperitoneal canal. The lack of fusion of the membrane with the transverse septum in the 8th-9th week of embryological development causes that the posterolateral portion of the diaphragm originating this type of hernia is not closed. Its incidence ranges from 1:2000...

We present the case of a 81-year-old male with clinical history of ischemic heart disease, who suffered a colonic perforation during an endoscopic examination and required emergency surgery. Resection of the sigmoid colon with an stapled end-to-end anastomosis was performed. In absence of skin coverage because of the necrosis, and with severe damag...

Introduction Hypoparathyroidism (hypoPT) is the most frequent complication after thyroid surgery, usually as transient hypocalcemia. Permanent parathyroid lesion is less frequent, but it can extend hospital stay and complicate postoperative management. Several preoperative factors predicting the development of hypoPT have been identified, including...

Objectives To describe the clinical characteristics and surgical treatment of patients with acute hypercalcaemia due to primary hyperparathyroidism (PHPT) and compare them with other patients with PHPT without associated acute hypercalcaemia.Material and methodsA prospective, observational study (1998-2010) was conducted on 158 patients with PHPT t...

Objectives1. To present the postoperative morbidity of complete thyroidectomies and the results of their clinical management and costs obtained after surgery. 2. To compare the results obtained for the morbidity and costs in the complete thyroidectomy Process, after the management changes introduced by the Endocrine Surgical Unit (ESU). 3. To defin...

Objectives To define the sensitivity of scintigraphy, ultrasonography and computed tomography (CT) in the topographic diagnosis of hy-perparathyroidism (HPT). To compare the results of two distinct sur-gical approaches, selected on the basis of the results of the tests. To study the effect of the above factors on the clinical management of the proc...

1. To assess the sensitivity of scintigraphy using methoxy isobutyl isonitrile (MIBI). 2. To compare its resolution with that of ultrasound (US) and computerized axial tomography (CAT). 3. To use its diagnostic reliability to determine whether selective approaches can be used to treat hyperparathyroidism (HPT). A study of 76 patients who underwent...

a) Valorar la sensibilidad de la gammagrafía con MIBI; b) comparar su resolutividad con la ecografía (ECO) y la tomografía computarizada (TC), y c) definir, a partir de su fiabilidad diagnóstica, si pueden efectuarse abordajes selectivos en el tratamiento del hiperparatiroidismo (HPT).
