Adhesions Of The Intestinal Coils, producing very manifold transpositions among themselves, and with the mesentery, with the colon, in reference to the hypogastric parietes of the abdomen and the pelvis, the bladder, and the internal sexual organs of the female; - adhesions of the omentum in various degrees with the hypogastric parietes of the abdomen, and more particularly of the inguinal region, and with the internal sexual organs of the female; the omentum may be folded together, or rolled up, and stretched across in a slanting direction to either of the inguinal regions, or it may descend with a furcate fissure to both, so as to attach itself at these points, and form a vertical, or, if passing under the colon transversum, a rounded horizontal band; thus giving rise to a species of diaphragm, which separates the mesogastric and hypogastric regions; - and adhesions of the parenchymatous viscera to the adjacent parietes and to the neighboring viscera.
Adhesions between the omentum and the colon, and the anterior parietes of the abdomen, are found chiefly in chronic peritonitis, but they are not of frequent occurrence.
The corded exudations may, in various ways, cause incarcerations of the intestine.
Or the exudations undergo metamorphoses, so as to give rise to tendinous or fibro-cartilaginous laminae, sometimes of uniform thickness, and with defined edges, sometimes of areolar or cribriform structure, at others, uneven, lobulated, granulated, thinning off towards the circumference, glued on to or fused with the thickened peritoneum. This is remarked, principally, on the omentum and the fold of the intestine in hernia, or on the hernial sac itself, and also on the convex surface of the spleen, on the liver, sometimes on the uterus and its appendages, and in rare cases on the entire extent of the peritoneum.
The chronic form of inflammation, which affects the exudations that have already been deposited, and creeps on with occasional exacerbations, presents the following peculiarities: It occupies the intestine only; or at least that part of the circumference of the intestine chiefly which is not affected by adhesions resulting from a previous process, as well as the opposed parietal surface, which in various degrees is limited by, or free from, adhesions. The consequence is the formation of a coagulum, which covers the anterior surface of the already agglutinated intestines, passing from them to the parietes, and thus inclosing a sacculated space which contains the fluid portion of the exuded matter. In such a case the intestines, and more particularly the small intestines, form a flattened round mass, riding upon the vertebral column, and invested anteriorly by the posterior lamina of a pseudo-membrane, which contains in its cavity a varying amount of fluid.
