Perianal rectal abscess

Acute purulent infection occurs in the anal canal and rectal soft tissue or in the surrounding space, and an abscess is formed, which is called anal canal and rectal abscess. Its characteristics are easy to rupture spontaneously, or easy to form anal fistula after surgical incision and drainage. It is a common anorectal disease, and it is also the acute phase of the anal canal and rectal inflammation pathological process. Anal fistula is its chronic phase. Common pathogenic bacteria include Escherichia coli, Staphylococcus aureus, Streptococcus and Pseudomonas aeruginosa, occasionally anaerobic bacteria and Mycobacterium tuberculosis, often mixed infection of multiple bacteria. It is worth noting that if the pus culture is Escherichia coli or anaerobic bacteria, the infection is mostly from the rectum, and anal fistulas are often formed after surgery, and often require reoperation. Eykyn reports 31%. If the culture is Staphylococcus aureus, the infection mostly comes from the skin, the chance of anal fistula after surgery is reduced, and it is rarely necessary to undergo another operation. Therefore, the bacterial culture results can be used as a reference for prognosis when the internal port is not found during the drainage.
