RACIONAL: O hemograma completo (CBC) e a proteína C-reativa (PCR) são úteis para excluir parâmetros inflamatórios e complicações inflamatórias agudas pós-operatórias. OBJETIVO: Determinar mudanças nesses parâmetros em pacientes com câncer gástrico submetidos à gastrectomia total. MÉTODOS: Estudo prospectivo com 36 pacientes com câncer gástrico submetidos todos à gastrectomia eletiva. No primeiro, terceiro e quinto dias pós-operatórios (PO), alterações do hemograma e as mudanças de PCR foram avaliadas. Os pacientes com complicações pós-operatórias foram excluídos. RESULTADOS: Vinte e um (58%) eram homens e 15 (42%) mulheres. A média de idade era de 65 anos. Os leucócitos atingiram o pico no primeiro PO com média de 13.826 u/mm³, e decresceram para 8.266 u/mm³ no quinto. Os bastonetes atingiram o pico no primeiro PO com valor máximo de 1,48%. O nível máximo da PCR foi no 3º PO, com média de 144,64 mg/l±44,84. O hematócrito pré-operatório (HCT) foi de 35% e de 33,67% até o 5o PO. A hemoglobina não apresentou alterações. CONCLUSÕES: Houve aumento de leucócitos no 1o PO mas atingiram valores normais até o 5o PO. PCR atingiu o pico no 3º PO, mas não atingiu os valores normais até o quinto.

BACKGROUND: The complete blood count (CBC) and C-reactive protein (CRP) are useful inflammatory parameters for ruling out acute postoperative inflammatory complications. AIM: To determine their changes in gastric cancer patients submitted to total gastrectomy. METHODS: This is a prospective study, with 36 patients with gastric cancer who were submitted to elective total gastrectomy. On the first, third and fifth postoperative day (POD), blood count and CRP changes were assessed. Patients with postoperative complications were excluded. RESULTS: Twenty-one (58%) were men and 15 (42%) women. The mean age was 65 years. The leukocytes peaked on the 1st POD with a mean of 13,826 u/mm³, and decreased to 8,266 u/mm³ by the 5th POD. The bacilliforms peaked on the 1st POD with a maximum value of 1.48%. CRP reached its maximum level on the 3rd POD with a mean of 144.64 mg/l±44.84. Preoperative hematocrit (HCT) was 35% and 33.67% by the 5th POD. Hemoglobin, showed similar values. CONCLUSIONS: Leukocytes increased during the 1st POD but reached normal values by the 5th POD. CRP peaked on the 3rd POD but did not reach normal values by the 5th POD.

Objective: To report a case of carcinoma ex pleomorphic adenoma on a young patient. Introduction: Carcinoma ex pleomorphic adenoma typically presents in patients in the sixth decade of life, with a history of parotid tumor of long standing. Alarm symptoms are present in 50% of cases and survival is mainly correlated with the degree of differentiation and tumor invasion. Case report: A 33 years old woman with right parotid tumor of five years of evolution with slow growing and no symptoms. During the last year, present accelerated growth and stabbing pain. Total parotidectomy was performed without complications or sequelae. The biopsy confirms carcinoma ex pleomorphic adenoma. Discussion: The long-standing pleomorphic adenoma may present malignant transformation in up to 12%. We discuss risk factors, clinical presentation and diagnosis of carcinoma ex pleomorphic adenoma.

Background: Laparoscopic sleeve gastrectomy (LSG) is used for the treatment of obesity and may provide gastric tissue for pathological studies. The association of obesity with dyslipidemias, diabetes and cardiovascular disease is of common knowledge. However its association with gastrointestinal diseases and gastritis is less well known. Aim: To analyze the pathological findings of the resected gastric segment during LSG. Material and Methods: Two hundred fifty patients aged 37 ± 12 years and with a body mass index of 37.7 ± 3.1 kg/m² (189 women), subjected to LSG, were included in a prospective protocol. Resected gastric segments were sent for a pathological study. Results: A gastric disease was identified in 220 (88%) cases. Chronic follicular gastritis was diagnosed in 117 patients (46.8%), chronic superficial gastritis in 76 (30.4%), chronic nonspecific gastritis in 38 (15.2%), intestinal metaplasia in 14% (5.6%) and in one case (0.4%) an early gastric carcinoma. Helicobacterpylori was present in 34 (13.6%) patients. Conclusions: This study shows a high prevalence of histopathological gastric lesions detected after the LSG, reaffirming the need for detection of these lesions before surgery.

Introducción: La gastrectomía vertical laparoscópica (GVL) es un procedimiento quirúrgico efectivo en el tratamiento de la obesidad. La obesidad está asociada con algunas comorbilidades como diabetes, dislipidemia y enfermedad cardiovascular, pero también se ha demostrado que tiene efectos potenciales sobre la gastritis y diversas enfermedades gastrointestinales. El objetivo de este estudio es determinar los hallazgos histológicos del segmento gástrico resecado durante la GVL realizada en una serie de pacientes obesos. Material y Método: Entre enero de 2006 y diciembre de 2008, 250 pacientes consecutivos a los que se realizó GVL, fueron incluídos en un protocolo prospectivo. La serie consistió en 189 mujeres (75,6%) y 61 hombres (24,4%), con edad promedio de 37,5 ± 12,1 años. El Índice de Masa Corporal (IMC) promedio fue 37,7 ± 3,1 kg/m². Resultados: Los resultados histológicos identificaron 220 casos (88%) con patología gástrica. Se diagnosticó gastritis crónica folicular en 117 pacientes (46,8%), gastritis crónica superficial en 76 (30,4%), gastritis crónica inespecífica en 38 (15,2%), metaplasia intestinal en 14% (5,6%) y en un caso (0,4%) adenocarcinoma in situ. Helicobacter pylori (HP) estuvo presente en 34 pacientes (13,6%). Conclusiones: Los hallazgos de este estudio, muestran una prevalencia incrementada de lesiones gástricas histopatológicas detectadas posterior a la GVL, reafirmando la necesidad de una detección de estas lesiones antes de la cirugía.

Introduction: Revisional bariatric surgery is performed to alter or repair one of the many types of weight loss surgery, including laparoscopic sleeve gastrectomy (LSG). The revision of bariatric procedures is required between 10 to 25% of patients operated, either by insufficient weight loss or complications, including stenosis. After a LSG, the Roux- en- Y gastric bypass (RYGBP) is the most requested surgery for conversion. The aim of this study was to describe a series of 5 patients who had revisional surgery for stenosis following LSG. Material and Method: Between January 2006 and March 2013, in 770 consecutive patients was performed LSG. Patients were included in a prospective protocol. Five patients had revisional surgery with conversion to RYGBP for stenosis following LSG. In three patients the initial LSG was performed in our hospital, the other 2 were from other hospitals. Results: In the 5 patients with revisional surgery mean age was 39.8 ± 15.7 years. Four patients were women (80%). The average BMI before LSG was 37.0 ± 2.1 kg/m² and BMI before RYGBP was 29.4 ± 5.4 kg/m². The RYGBP was laparoscopic in 3 cases and opened in two. There were no complications, and no mortality. Conclusions: Conversion to RYGBP is an effective treatment for stenosis following a LSG.

Introducción: La cirugía bariátrica revisional se realiza para modificar o reparar alguno de los tipos de cirugía para perder peso, entre ellos la gastrectomía vertical laparoscópica (GVL). La revisión de procedimientos bariátricos se hace necesaria entre el 10 al 25% de los pacientes, ya sea por baja de peso insuficiente o por complicaciones, siendo la estenosis una de ellas. Posterior a una GVL, el bypass gástrico en Y de Roux (BPG) es la intervención quirúrgica más requerida para la conversión. El objetivo de este estudio fue describir una serie de 5 pacientes que tuvieron cirugía revisional por estenosis posterior a una GVL. Material y Métodos: Entre enero de 2006 y marzo de 2013, en 770 pacientes consecutivos se realizó GVL. Los pacientes fueron incluidos en un protocolo prospectivo. Cinco pacientes tuvieron cirugía revisional con conversión a BPG por estenosis posterior a la GVL. Tres pacientes fueron operados de GVL en nuestro hospital, los otros 2 provenían de otros centros hospitalarios. Resultados: En los 5 pacientes con cirugía revisional la edad promedio fue 39,8 ± 15,7 años. Cuatro pacientes fueron mujeres (80%). El promedio IMC antes de GVL fue 37,0 ± 2,1 kg/m² y del IMC antes del BPG fue 29,4 ± 5,4 kg/m². El BPG fue laparoscópico en 3 casos y abierto en 2. No hubo complicaciones, ni mortalidad. Conclusiones: La conversión a bypass gástrico en Y de Roux es un tratamiento efectivo para la estenosis posterior a una GVL.
