[Tumors and cysts of the mesentery. Clinical and therapeutic study].
This study is based on a group of 34 primary tumours of the mesenterium which were treated in the first surgical Clinic between 1960 and 1981. In this series were 19 women and 15 men, and the age of the patients varied between 16 and 68 years, being in the average of 44 years. Ten cystic tumours were recorded, and 24 solid tumours. Nine of the tumours were benign and the remaining 25 were malignant. The cystic tumours, for the most of the benign type, were almost exclusively cystic lymphangiomas. One serous cyst was also recorded, as well as one hematic cyst, and one dermoid cyst that had underwent malignization. The solid tumours were all malignant, of the sarcomatous type,, and their starting point was the mesenteral connective-vascular structures. The clinical picture of the mesenteral tumours is polymorphous and non-characteristic. In the frame of paraclinical examinations the radiologic investigation holds an important place and this is especially true for selective arteriography of the upper mesenteric artery, which provides useful informations concerning the topography of the tumour in relation to the mesenteral vascular trunk. Therapeutic possibilities are discussed, and the fact is stressed that, for improving the prognosis an early diagnosis is essential.
