RESUMOIntrodução: A melhoria da acuidade diagnóstica do enfarte do omento resultou num incremento da atitude conservadora no seu tratamento. Com o objectivo de avaliar a eficácia e segurança da abordagem não-operatória, analisámos os casos de enfarte do omento tratados num hospital terciário. Material e Métodos: Incluímos os casos de enfarte do omento primários tratados entre 2004 e 2011. Os enfartes do omento diagnosticados por imagiologia foram submetidos a tratamento conservador que constou de analgésicos e antibioterapia intravenosa. Avaliámos os dados demográficos, apresentação clínica, dados laboratoriais, imagiologia e resultado. Resultados: Ocorreram nove casos de enfarte do omento. Oito pacientes (4 rapazes), com uma idade mediana de 8,5 anos, apresentaram-se na fase inicial da doença por dor abdominal à direita; a contagem leucocitária era normal ou ligeiramente elevada. Seis casos, diagnosticados por TC após ecografia suspeita de enfarte do omento em quatro, foram trados conservadoramente sem complicações, tendo alta ao terceiro dia (mediana). Dois doentes foram apenas diagnosticados durante a intervenção cirúrgica por suposta apendicite. O nono caso apresentou-se com uma obstrução intestinal devida a hérnia interna que foi resolvida por laparoscopia. Discussão: A imagiologia foi diagnóstica na maioria dos casos de enfarte do omento, permitindo a adoção de uma abordagem conservadora. O tratamento não-operatório foi eficaz e sem complicações em todos os doentes que se apresentaram na fase inicial da doença. Um doente apresentou-se com uma complicação grave que requereu intervenção cirúrgica. Conclusão: Na ausência de um tratamento consensual para o enfarte do omento, a abordagem não-operatória é uma alternativa não invasiva e eficaz, mas requer uma vigilância clínica ativa.

In order to assess the efficacy and safety of conservative management, we surveyed the cases of omental infarction treated at a single institution. Material and Methods: Primary omental infarction treated between 2004 and 2011 were reviewed. Cases recognized by imaging studies were submitted to conservative treatment that consisted of intravenous analgesics and antibiotics. Demographics, clinical presentation, laboratory findings, imaging diagnosis and outcome were analyzed.Results: There were 9 cases of omental infarction. Eight patients (4 males; median age, 8.5 years) presented at initial course of disease; all had right-sided abdominal pain and a normal or lightly increased leukocyte count. Six cases, diagnosed by CT scan after US suspicion in four, were managed conservatively, recovered uneventfully, and were discharged after a median hospital stay of 3 days. Two patients were only recognized at surgery. An additional case presented with intestinal obstruction due to an internal hernia and was successfully resolved by laparoscopy. Discussion: Imaging techniques were d...
Introduction: Superior mesenteric artery syndrome (SMAS) is a rare acquired disorder, which in the present case had an acute and unusual way of presentation. Case Report: We present a 17-year-old female with nausea, vomiting, and intense epigastric pain. In the previous 6 months, she had lost 42% of her body weight. The echography showed a distended stomach that reached the pelvis, and the nasogastric tube that was placed drained 2,000 mL. A computed tomography scan confirmed the SMAS diagnosis. She started a hypercaloric fractionated meal diet, prokinetics, and postural measures. After the 1-year follow-up the patient is asymptomatic. Conclusion: This acute presentation is rare but life-threatening due to the possibility of gastric rupture. Medical management is possible in the majority of cases, and surgery is needed only in the refractory ones.
