APPROXIMATELY 500 cases of mesenteric cysts of all types had been reported in the literature up to 1935, and it is conjectured that between 200 and 300 were of the chylous variety.* In 1947, Beahrs and Judd reported an incidence of 7 chylous cysts in over 1,000,000 patients at the Mayo Clinic.3 Block estimates that 1 case of chylous mesenteric cyst occurs in 150,000 admissions in general hospitals.4
Chylous cysts vary in size, are usually single, and lie between the peritoneal leaves of the mesentery of the small bowel, usually the jejunum. Since they are not tensely filled, they tend to be flabby. A dumbbell shape is common, with the cyst projecting out from either side of the mesentery, partially surrounding a loop of bowel, like a saddle. The walls are thin, consisting of connective tissue and an inner lining of endothelial cells. Gross emphasizes the absence of
