Abscess Ischiorectal

Ischio-rectal abscess (deep sinus abscess) is an inflammatory disease of the tissue between the rectum and the outer surface of the sacrum. This abscess is a consequence of infection from the lymphatic channel located between the sacrum and rectum. Such an infection may occur as a result of a postoperative complication. It can also occur with diseases such as coccydynia, Crohn's disease, diverticulitis, perianal fistulas.

The abscess begins as phlegmon and as pus accumulates, an infiltrate can form. The infiltrate is a conglomerate of inflamed tissue containing pus, blood, tissue fluid and phagocytic leukocytes. About
