[Mesenteric cyst].

Mesenteric cysts are rare abdominal tumors. Their incidence varies in different papers from one in 27,000 to one in 250,000 hospital admissions. Five patients with mesenteric cysts were treated at Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo between November 1982 and October 1992. The most common location was in the small bowel (60%). All of them were treated by surgery. One case was found incidentally. Treatment of choice is enucleation. It was realized in two cases (40%). The others had segmental bowel resection.
