The diseases of women : a handbook for students and practitioners . far less frequently fatal than that which follows septicendometritis. The direct channels established by the Fallopian tubesbetween the cavity of the uterus and the ccelom (generalperitoneal cavity) facilitate peritoneal infection. But its fre-quency is diminished in a very important manner by occlu-sion of the abdominal ostia of the tubes—a pathologicalsequence of great value in so far as the saving of life isconcerned. Occlusion of the Ostium.—When inflammation ex-tends from the tubal mucous membrane to the peritoneum adjacent to the ostium, itleads to the formation ofadhesions in consequenceof the organization of theexudation, which leads tothe matting together ofthe tubal fimbriae; thisalso glues them to theovary and posterior layerof the broad ligament, andoccasionally to a coil ofintestine. This mechanic-ally seals the ostium. There is another in-teresting and probablyslower way in which these ostia become occluded. Thefimbriae are luxuriant protrusions of tubal mucous mem-.

When the tubes are inflamedthe muscular and serous coats lengthen and bulge over thefimbriae until each ostium appears as a rounded smooth ori-fice instead of being fringed ; gradually the rounded marginscontract, cohere, and occlude the opening. In the earlystages, if the rounded end of the occluded tube be slit up,the fimbriae will be found crowded inside the tube. Thismode of occlusion is termed salpingitic closure of theostium (Fig. 75). This sealing up of the ostium is a remarkable and con-servative process in so far as the life of the individual isconcerned. The occluded tube now becomes the seat ofimportant changes whereby it is converted into a pyosal-pinx, a hydrosalpinx, or undergoes sclerosis. Pyosalpinx.—This may be defined as a Fallopian tub
