Cisto mesentérico: aspectos clínicos e anátomopatológicos / Mesenteric cyst: clinical and pathological aspects

OBJETIVO: Discutir aspectos epidemiológicos, clínicos, anátomo-patológicos e terapêuticos de cistos mesentéricos atendidos em hospitais do Estado de Sergipe. MÉTODOS: Estudo observacional, descritivo e transversal, consistindo de um levantamento de uma série de casos de cistos mesentéricos, nos arquivos do Laboratório de Patologia da Universidade Federal de Sergipe no período de 1995 a 2007. Revisaram-se os prontuários dos pacientes para coleta de dados: gênero, idade, quadro clínico, exames complementares e abordagem terapêutica. RESULTADOS: Foram encontrados 18 casos de cistos mesentéricos. O gênero predominante foi o feminino (72,2 por cento). A média de idade dos pacientes ao diagnóstico foi de 30,48 anos. Os sintomas mais freqüentes foram dor e massa abdominal. A ultra-sonografia de abdome, realizada em todos os pacientes, não foi conclusiva em metade dos casos. Tomografia computadorizada de abdome com contraste foi realizada em seis casos, sendo a tumoração cística bem evidenciada em todos estes. Quanto ao tipo histopatológico foram encontrados oito linfangiomas, oito cistos mesoteliais, um cisto hemorrágico em organização e um cisto mucinoso. O tratamento cirúrgico foi empregado em todos os casos. Hemorragia intracística foi a principal complicação apresentada, ocorrendo em três casos. CONCLUSÃO: Os cistos mesentéricos apresentaram-se clinicamente com sintomas inespecíficos e pouco sintomáticos. Quanto ao diagnóstico, a tomografia computadorizada mostrou ser mais efetiva que a ultrassonografia. Linfangiomas e mesoteliomas foram encontrados em proporções iguais. A ressecção completa do cisto foi o tratamento de eleição e não houve óbitos no pós-operatório.

OBJECTIVE: To evaluate epidemiologic, clinical, pathologic and therapeutic characteristics of the mesenteric cysts in hospitals of Sergipe, Brazil. METHODS: Mesenteric cysts were assessed by a non-interventional cross-sectional study from the archives of the Pathology Laboratory of Federal University of Sergipe between 1995 and 2007. The charts of the patients were reviewed in order to find out: gender, age, clinical findings, complementary exams and therapeutic approach. RESULTS: Eighteen cases of mesenteric cysts were found. Females were more affected (72.2 percent). Mean of age of the patients was 30.46. More frequent symptoms were pain and abdominal mass. Ultrasonography of abdomen, performed in all patients, was not conclusive in half of the cases. CTscan of abdomen with contrast was performed in six cases, being cystic tumor well identified in all of them. Regarding histopathology, 6 lymphangiomas, 8 mesotheliomas, 1 hemorrhagic cyst in organization and 1 mucinous cyst were found. Surgical treatment was performed in all cases. Intracystic bleeding was the main complication in 3 cases. CONCLUSION: The mesenteric cysts presented clinically with unspecific symptoms. CTscan was more effective than ultrasonography for the diagnosis. Lymphangiomas and mesothelioma had been found in equal ratios. The complete ressection of the cyst was the treatment of election. There were no deaths in postoperative period.

Quiste del mesenterio: reporte de un caso y revisión de la literatura / Mesenteric cyst: a case report and literature review

El quiste mesentérico es una entidad poco frecuente que se ha definido como cualquier lesión quística localizada en el mesenterio, y se subdivide, según su origen, en tumores linfáticos, mesoteliales, urogenitales, dermoides, entéricos y seudoquistes. Recientemente atendimos en nuestro hospital a un paciente del sexo masculino, de 61 años de edad, ingresado a causa de dolor abdominal difuso, que se llevó al salón de operaciones con el diagnóstico de oclusión intestinal por bridas. Durante el acto quirúrgico se encontró un quiste del mesenterio, aproximadamente de 8 a 10 cm, por lo que fue necesario realizar una resección intestinal, siendo la evolución posoperatoria favorable. La baja incidencia de la enfermedad y la creencia errónea de que se trata de un proceso benigno y asintomático han contribuido al escaso interés por su conocimiento(AU)

The mesenteric cyst is an uncommon entity localized in the mesentery and it is subdivided, according to its origin into lymphatic, mesothelial, urogenital, dermoid, or enteric tumors, and pseudocysts. Recently. we received in our hospital a 61-year-old male patient that was admitted due to a diffuse abdominal pain. He was taken to the operating room with the diagnosis of intestinal occlusion caused by bands. During the surgical procedure, it was found a mesenteric cyst of approximately 8-10 cm, which made necessary to perform intestinal resection. The postoperative evolution was satisfactory. The low incidence of the disease and the erroneous belief that it is a benign and asymptomatic process have contributed to the little interest in knowing about it(AU)

Clinical Studies of Abdominal Tumors in Infants and Chi1dren: Ten Year Review

We have clinically observed 39 patients with abdominal tumors who were admitted in Severance Hospital during the past 10 years from April 1960 to March 1970. Unfortunately follow-up study couldn't be made. The following results were obtained. 1) Of the total number observed, 25 patients were male and 14 patients female. 2) The majority of the patients, 34 (87%) were under 6 years of age and 20 (51%) were between 1 to 3 years of age. The youngest patient was a 3-month-old female with Wilms' tumor. 3) In our series, Wilms' tumor (15 cases, 38.5%) was the most common and neuroblastoma (8 cases) was next most common tumor in the abdominal cavity. In addition we found another 4 cases of neuroblastoma in other sites. We observed hepatoma (8cases), ovarian tumor (3cases), lymphosarcoma (2cases), mesenteric cyst (one case) and adenoma of the left adrenal gland (one case) in that order of frequency. 4) In 15patients with Wilms' tumor, hypertension was observed in 8 patients and hematuria in 4 patients. Compared with Wilms' tumor, no hematuria was noted in the cases with neuroblastoma and hypertension occurred in 3 of these. 5) On abdominal X-ray, calcification was present in 4 cases with neuroblastoma (50%) and was present in only one of 15 patients with Wilms' tumor. 6) Comparing the sites of metastasis between Wilms' tumor and neuroblastoma, 4 of 15 patients with Wilms' tumor had lung metastasis and 4 of 8 patients of neuroblastoma had bony metastasis. Liver metastasis was found at autopsy in one case of neuroblastoma. 7) Three cases of hepatoblastoma were under 2 years of age and three cases of hepatocarcinoma were over 12 years of age. 8) Three cases of ovarian tumor were benign cystic teratoma. Tortion of the ovarian pedicle occurred in one of 3 patients with severe low abdominal pain. All patients were discharged in good condition after salphingo-oophorectomy. 9) One case of lymphosarcoma of the ileum was associated with intussusception. 10) A one year o1d female with adenoma of the left adrenal gland had typical Cushing's syndrome.
