The subject of inflammation of the tissues surrounding the uterus and its appendages would be very much simplified, especially for the general practitioner, by debarring it of all new and superfluous names and subdivisions, and by treating it on a broad clinical basis. It will be my aim in this paper to keep that idea constantly in view, rather than to follow the history and varying pathological views by which it has been surrounded and complicated. The importance of this disease is probably greater in its influence on the health and future usefulness of the woman than any other; and its causes and prevention, as well as its early recognition and treatment, should be fully understood by the physicians who are most likely to be first consulted in the matter, those engaged in general practice. I feel safe in making the statement that were this so, many of the chronic cases of almost incurable displacement of the uterus, Fallopian tubes, and ovaries, resulting from thickened, indurated, and contracted ligaments, with their distressing symptoms, would never reach the gynecologist, because they would not then exist. In many cases the disease would have been prevented; in others it would have been arrested in its incipiency. Whether we understand the primary pathological lesion to be inflammation of the cellular tissue, the peritoneum, the lymphatics, or the veins, matters very little, practically, if we recognize the immediate location of the process; for there can be no doubt that the disease, once started, soon involves to a greater or less degree all of the tissues and organs adjacent to it, and the therapeutic requirements will be much the same in either case. That inflammation of the cellular tissue can exist without also involving the peritoneum in its neighborhood is scarcely to be conceived, and vice versâ; but the one has always a predominating influence over the other, and differs somewhat in its cause, course, and consequences. When the inflammatory process has its origin in the cellular tissue, it is more likely to run through a regular course and end in abscess than if it had started as a peritonitis, in which case the course of the disease is often more chronic, resulting in the formation of false membranes which bind the uterus and other pelvic organs in permanent displacement. For these reasons, and for the more systematic study of the subject, I think it best to follow the plan of those authors who describe the disease separately under the two general heads, Parametritis and Perimetritis. {209} Parametritis.[1] [Footnote 1: Virchow, Duncan.]
