DIAGNOSIS.—The symptoms resemble closely in kind, but differ in degree from, the appearances in acute metritis. The uterus is smaller and not so painful on pressure. The endometrium is sensitive to the slightest touch—a fact elicited upon the passage of the sound. The characteristic symptom is the discharge from the uterine cavity of a more or less profuse secretion possessing the character already mentioned. An absolute differential diagnosis is impossible, nor is it necessary, seeing that the treatment of the two conditions is nearly identical.

PROGNOSIS.—Acute endometritis terminates in resolution or chronic inflammation. The latter mode of termination is of more frequent occurrence, particularly in the presence of gonorrhoea, sepsis, and the like as etiological factors. The disease endangers life when the peritoneum is involved by the propagation of the inflammatory process along the tubes or through the uterine parenchyma. Then the acute endometritis may be the starting-point of general septic infection through the media of the veins and lymphatic vessels.

TREATMENT.—Absolute rest in bed, the relief of pain by morphine, the evacuation of the bowels by enemata or mild laxatives, the free imbibition of bland mucilaginous fluids for the vesical tenesmus,—are measures which usually fulfil all indications for treatment. Even in the case of gonorrhoeal infections astringent applications to the endometrium are contraindicated. Usually, various complications mark the endometritis, the starting-point of the pathological condition, and these complications demand more active interference.

Chronic Endometritis.

ETIOLOGY.—Attention has been called to the etiology of chronic metritis in a somewhat detailed manner. The limits of this paper will not admit of adequate mention even of the more common causative factors of chronic endometritis. All the conditions which determine an active fluxion or passive hyperæmia of the uterus may operate as causative factors. Hypersecretion of mucus is frequently observed in chlorotic, scrofulous, and tuberculous females. Syphilis and gonorrhoea are potential causative agents. Climate seems to exercise a more or less direct influence. Thus, we are informed by Schroeder41 that chronic endometritis is observed with relative frequency in damp, cool regions, such as Holland, Belgium, and certain parts of England. Europeans who reside in hot climates—for example, the Englishwomen living in India—are said to be affected with leucorrhoea to a degree entirely out of proportion to local or constitutional causes.

PATHOLOGICAL ANATOMY.—An analogy of striking character exists between the structural changes in chronic endometritis and chronic metritis. In chronic endometritis, as in chronic metritis, it is possible to clearly distinguish two stages in the inflammatory process. In the first, or stage of infiltration, a more or less acute inflammation is observed, which involves, primarily, the interglandular connective tissue; secondarily, the glands themselves. When the stage of infiltration does not terminate in resolution with the resorption of the exudate, the newly-formed connective-tissue elements contract, and the glands are to a greater or less degree obliterated.

1. Chronic Catarrhal Endometritis.—The endometrium during the first stage is swollen, vascular, soft, and succulent. Small extravasations of blood and pigmentary deposits from ecchymoses are observed in the interacinous connective tissue. The surface of the mucous membrane is smooth or roughened in spots. The orifices of the glands are visible. The mucous membrane of the cervix is infected, its transverse folds distended, the follicles filled with mucus, the canal plugged with tenacious turbid secretion; the vaginal portion is enlarged, spongy, and its mucous membrane exhibits hypertrophic changes in the papillary body. The os externum is frequently patulous. The uterine walls having undergone excentric hypertrophy, the cavity is usually enlarged, and contains a translucent alkaline secretion which resembles mucus.

Microscopical examination of the endometrium reveals a variety of structural changes. A luxuriant development of embryonal connective-tissue elements is observed with relative frequency in the interacinous connective tissue. Olshausen has applied the term chronic hyperplastic endometritis to this condition. The term chronic interstitial endometritis has been more generally accepted. While the newly-formed connective-tissue elements are soft and succulent, hemorrhages are frequent.
