[Mesenteric cyst--clinical and pathological aspects].

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%). 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 resection of the cyst was the treatment of election. There were no deaths in postoperative period.
