Tubulovillous adenoma of the duodenal papilla: radiological-endoscopic and anatomopathological correlation in the surgical proposal.

Tubulovillous adenomas of the duodenal ampulla are rare neoplasms. The present report describes a case with radiological-endoscopic and pathological correlation in which the patient underwent duodenal pancreatectomy with good postoperative progression. With advanced imaging methods, especially magnetic resonance and endoscopic ultrasound, locoregional aspects and extraluminal, lymphovascular, and metastatic invasion have been increasingly discussed as contributors to therapeutic decision making. This progression improves lesion staging and is especially useful in selecting eligible candidates for endoscopic treatment.

SUMMARY Tubulovillous adenomas of the duodenal ampulla are rare neoplasms. The present report describes a case with radiological-endoscopic and pathological correlation in which the patient underwent duodenal pancreatectomy with good postoperative progression. With advanced imaging methods, especially magnetic resonance and endoscopic ultrasound, locoregional aspects and extraluminal, lymphovascular, and metastatic invasion have been increasingly discussed as contributors to therapeutic decision making.

RESUMO Os adenomas túbulo-vilosos da ampola duodenal são neoplasias raras. Neste trabalho apresentamos um caso com correlação radiológico-endoscópica e patológica, tendo a paciente sido submetida à duodenopancreatectomia com boa evolução pós-operatória. Com os avanços dos métodos de imagem, em especial da ressonância magnética e ultrassonografia endoscópica, aspectos locorregionais, além da invasão extraluminal, linfovascular e metastática, têm sido discutidos de maneira crescente como contribuintes na decisão terapêutica. Essa evolução contribui para o melhor estadiamento destas lesões e é especialmente útil para selecionar candidatos elegíveis ao tratamento endoscópico.

Spontaneous intracranial hypotension and its complications.

Spontaneous intracranial hypotension (SIH) is a syndrome that was unknown until the advent of magnetic resonance imaging (MRI). It is a cause of orthostatic headache, which remains underdiagnosed and, rarely, can result in several complications including dural venous sinus thrombosis, subdural hematoma and subarachnoid hemorrhage. Some of these complications are potentially life-threatening and should be recognized promptly, mainly by imaging studies. We reviewed the MRI of nine patients with SIH and describe the complications observed in three of these patients. Two of them had subdural hematoma and one had a dural venous sinus thrombosis detected by computed tomography and MRI. We concluded that MRI findings are of great importance in the diagnosis of SIH and its complications, which often influence the clinical-surgical treatment of the patient.

RESUMO Hipotensão Intracraniana Espontânea (HIE) é uma síndrome desconhecida até o advento das imagens de Ressonância Magnética (RM). É uma causa de cefaleia ortostática que permanece subdiagnosticada e raramente resulta em complicações, como trombose de seios venosos durais, hematoma subdural e hemorragia subaracnoidea. Algumas dessas complicações são potencialmente ameaçadoras à vida e devem ser prontamente reconhecidas pelos estudos de imagem. Nós revisamos as RM de 9 pacientes com HIE e descrevemos as complicações observadas em 3 casos. Dois deles tiveram hematoma subdural e um teve trombose de seio venoso dural detectados por tomografia computadorizada e RM. Concluímos que achados de RM são de grande importância no diagnóstico de HIE e suas complicações, frequentemente influenciando o tratamento clínico-cirúrgico do paciente.

Case study of stomach adenocarcinoma conducted at a cancer referral hospital in northern Brazil.

CONTEXT: Stomach cancer is the second leading cause of death due to cancer in the world and the incidence of this disease continues to be high in Brazil. In the Northern region, gastric cancer is the second most frequent cancer among men and the third among women. In the State of Pará, stomach adenocarcinoma is a public health problem since mortality rates are above the Brazilian average. OBJECTIVE: To analyze the clinical and anatomopathological profile of stomach adenocarcinoma in patients seen at Ofir Loiola Hospital. METHODS: In a retrospective study, records from 302 patients with gastric cancer undergoing surgery between 2006 and 2008 were analyzed. Data regarding patient profile, early symptoms, alterations upon physical examination, type of surgery, and macroscopic and histological findings were obtained from the records. RESULTS: Most patients (63.9%) were men, 48% were older than 60 years, 50.9% were from the metropolitan region of Belém, 68.2% presented epigastric pain as an early symptom, and abdominal tenderness upon palpation was observed in 63.7%. The antrum was the most affected anatomical site (62.1%), followed by the gastric body (26.9%). Borrmann III (ulcerated-infiltrative) was the predominant endoscopic type. Adenocarcinoma accounted for 95.4% of all cases, including the intestinal type in 56.6% and the diffuse type in 41.3%. Most patients had stage IIIB and IV tumors and total gastrectomy was the most frequent type of surgery (37.4%). CONCLUSION: The present study demonstrated that gastric adenocarcinoma mainly affected men over the age of 60 who were from the metropolitan region of Belém. Most adenocarcinomas were in an advanced stage at the time of diagnosis, a fact requiring more aggressive surgical resection in these cases. These data highlight the urgent need for the implementation of preventive measures and early detection programs of gastric cancer.

CONTEXTO: O câncer gástrico é a segunda causa de morte relacionada à neoplasia no mundo e o Brasil ainda apresenta taxas consideradas elevadas desta doença. Na região norte, o câncer gástrico é o segundo mais frequente entre homens e o terceiro em mulheres. No estado do Pará, o adenocarcinoma gástrico ainda constitui problema de saúde pública, pois as taxas de mortalidade apresentam valores acima da média brasileira. OBJETIVOS: Analisou-se o perfil clínico e anatomopatológico do adenocarcinoma gástrico em pacientes do Hospital Ofir Loiola. MÉTODOS: Foi realizado estudo retrospectivo de 302 prontuários de pacientes com câncer gástrico que foram submetidos a cirurgia no período de 2006 a 2008. Foram retirados dados dos prontuários relativos ao perfil dos pacientes, sintomas iniciais apresentados, alterações ao exame físico, tipo de cirurgia realizada, achados macroscópicos e histológicos do tumor. RESULTADOS: A maioria dos pacientes (63,9%) era do sexo masculino, 48% tinham mais de 60 anos; 50,9% eram oriundos da mesorregião metropolitana de Belém; 68,2% apresentaram dor epigástrica como sintoma inicial e 63,7% apresentaram dor abdominal ao exame físico. A região anatômica mais acometida foi o antro (62,1%), seguido do corpo (26.9%). O aspecto endoscópico predominante foi o Borrmann III - úlcero-infiltrante. O adenocarcinoma representou 95,4%, sendo 56,6% do tipo intestinal e 41,3% do tipo difuso. A maioria encontrava-se no estágio IIIB e IV e a gastrectomia total foi o tipo de cirurgia mais realizado (37,4%). CONCLUSÃO: No presente estudo, foi demonstrado que o adenocarcinoma gástrico acometeu principalmente homens acima da sexta década de vida, procedentes da mesorregião metropolitana de Belém, e em sua maioria as lesões eram avançadas no momento do diagnóstico, resultando em ressecção cirúrgica mais agressiva nesses casos. Estes dados vêm enfatizar a imperiosa necessidade da implementação de medidas preventivas e de diagnóstico precoce do câncer gástrico.
