ENTEROKISTOMA

From Big Medical Encyclopedia

ENTEROKISTOMA (enterocystoma; Greek enteron a gut + kystis a bubble + - orna) — seldom found intra belly cyst which is formed of a persistent embryonal umbilical and intestinal (vitelline) channel. Normal by the end of the second month of pre-natal development the umbilical and intestinal channel (ductus omphaloentericus) is obliterated. At a delay of this involute process the remains of a channel can be a source of development of an enterokistoma, and also Mekkel's diverticulum (see Mecca la a diverticulum) and inborn fistulas of a navel (see the Navel, umbilical area).

Most often E. are located in a distal part of a small bowel near the ileocecal valve (the baugini-evy gate), approximately at the place of an otkhozhdeniye umbilical enterogo a channel in the embryonal period. Usually E. is between leaves of a mesentery, but cases of an arrangement E are described. and in other places of an abdominal cavity, sometimes vnebryu-shinno. AA. can remain connected with a gut by means of a thin connecting tyazh. AA. usually contains the liquid consisting of slime with impurity of a sawn-off epithelium and cholesterol. Idiosyncrasy E. the structure of its wall containing structural elements of a gut — a cylindrical epithelium, scyphoid cells, whether-berkyunovy glands, fibers, smooth muscle cells is. In some cases E. reaches the huge sizes, causing a prelum of intestinal loops and the phenomenon of impassability (see Impassability of intestines); sometimes the picture of the overwound cyst develops. Quite often E. abscess that is clinically shown by a picture of local or general peritonitis (see).

Treatment operational. The forecast at timely treatment favorable.
