Tireoidectomia total nas doenças benignas da tireóide

OBJECTIVE To review the indications for total thyroidectomy as the preferred option in certain benign diseases of the thyroid in order to prevent recurrence or future reoperations. METHODS A retrospective study of patients with benign thyroid diseases, carried out from January 1997 to December 2009, analyzing the data relating to age, surgical treatment and postoperative evolution. RESULTS The mean age was 51.8 years (21/77), with the highest incidence in the fifth and sixth decades of life, with 34 (51.5%) patients. The most common preoperative diagnosis was nontoxic multinodular goiter, of which seven were also intrathoracic, followed by autoimmune thyroiditis; recurrent goiter occurred in 11 cases. Multinodular goiter was found in 37 (56.1%) patients, autoimmune thyroiditis in 22 (33.3%), follicular adenoma isolated in five (7.6%), Hurthle cell adenoma in two (3.0%). Sixteen patients (24.2%) had more than one histopathological diagnosis. Permanent injury of the recurrent nerve was observed in one patient (1.5%). There was no case of permanent hypoparathyroidism. There was no operative mortality. CONCLUSION Total thyroidectomy is an operation that can be safely performed, with low incidence of permanent complications, which allows one to broaden its indications in various benign thyroid diseases, thus avoiding future recurrences and reoperations.

Adenocarcinoma gástrico Borrmann tipo IV: análise dos resultados da ressecção curativa

OBJECTIVE To evaluate the results obtained with curative resection of Borrmann IV gastric adenocarcinoma (B IV) through the analysis of clinical, surgical and pathological data, identifying which of these prognostic factors were associated with survival. METHODS We retrospectively analyzed 123 patients with B IV gastric adenocarcinoma undergoing surgical treatment at the Department of the pelvic-abdominal surgeries of the National Cancer Institute (INCA) from January 1997 to December 2005. The group undergoing curative resection was examined for various prognostic factors regarding overall survival. RESULTS Of the 123 patients studied, 68 underwent gastrectomy, 52 (42.3%) with curative intent and 16 (13%) palliative resection, while 55 (44.7%) had disease not subject to resection. Three postoperative deaths followed the curative resection, constituting a mortality rate of 5.76%. In nine (17.3%) patients there were technical complications, and esophagojejunal fistula seven cases, the most frequent. All technical complications and deaths occurred after total gastrectomy, which was the most commonly performed curative resection type in this series. The most common pattern of recurrence was peritoneal carcinomatosis. The location of the tumor, lymph node metastasis, lymphatic invasion and pathological staging were considered significant prognostic factors. The median survival time was 29 months, with a rate of five-year survival of 33% in patients undergoing curative resection. CONCLUSION The curative resection of B IV gastric adenocarcinoma had a positive impact on survival of patients with the disease in stages IB, II and III, with up to 15 lymph nodes (pN2) and localized type.

Endometrioma de parede abdominal

BACKGROND: The exact incidence of endometriosis in the general population is unknown. Confirmation of this disease is only possible by histopathological analysis of a fragment obtained by some invasive procedure, because there is so far, no clinical secure marker. AIM: To report the experience with the clinical manifestations and surgical treatment in patients with abdominal wall endometrioma. METHODS: Retrospective analysis of patients operated for abdominal wall endometrioma with emphasis on data relating to age, symptoms, previous cesarean, relation of symptoms with the menstrual cycle, physical examinations and additional surgical treatment, postoperative course and histopathological results of specimens. RESULTS: Forteen patients were operated during the study period, aged between 28 and 40 years. The presence of local mass and pain that worsened during menstruation were the main complaints. Ultrasound and CT examinations were important to precisely localize the disease. Surgical excision was a wide excision of the tumor and affected tissues. The patient progressed satisfactorily and histopathology confirmed the diagnosis of abdominal wall endometrioma in all cases. CONCLUSION: Exists a clear relationship between cesarean operation and abdominal wall endometrioma; ultrasound studies and CT scans help to plan the surgical resection allowing resection of tumor and all affected adjacent tissues.

Pancreatic pseudocyst with splenic involvement: case report

The authors present a case report of a pancreatic pseudocyst with an unusual spleen involvement. The aspects of this rare complication are discussed, as well as the probable etiologic factors. The outcome was satisfactory and the surgical treatment consisted of the resection of its thick capsule, since the local anatomic conditions would not permit a splenectomy with distal pancreatectomy, considered to be the ideal surgery.

Hiperaldosteronismo primário: relato de dois casos

The authors present two cases of Primary Hiperaldosteronism, caused by functioning adenoma of the adrenals cortex. The two females patients presented classic symptoms of the Conns disease, especially hypocalemia and hypertension. Both were operated and unilateral adrenalectomy was done, with excelent outcome in one and satisfactory in the other one. It is discussed many aspects related to the incidence, the problems with the diagnosis, indication and surgery treatment.

Apendicite epiplóica com comprometimento da serosa e estreitamento da luz do sigmóide: relato de caso

Os autores relatam o caso de um paciente de 34 anos, submetido a laparotomia de urgencia com quadro de abdomen agudo ocasionado por apendicite epiploica. Foi dado enfase a manifestacao intensa dos sinais e sintomas, assim como sua apresentacao pouco usual no ato cirurgico, uma vez que comprometia o sigmoide sugerindo tratar-se de doenca de Crohn.
