Periproctal inflammations related to the anus are characterized by the rapid spread of the infection to the surrounding tissue, which is determined by the anatomical characteristics and infectious agents. Inflammation, which starts as a phlegmon, quickly forms boundaries and an abscess develops in most cases. Up to 80-90% of anorectal abscesses develop according to the crypto-glandular theory on the basis of infection of the anal glands, spilling into the Morgagni crypts in the anal canal. Up to two-thirds of such abscesses are associated with the emergence of anorectal fistulas. Anorectal abscesses can be divided into marginal and subcutaneous perianal abscesses, submucosal, intersphincteric, ischiorectal and supralevator abscesses. Their diagnosis is based on thorough physical examination, sometimes also with the help of imaging methods such as computed tomography, magnetic resonance imaging and endoanal ultrasound. What is decisive for the successful treatment of anorectal abscessess is their early and adequate surgical drainage. Adjuvant antibiotic therapy is necessary only when the overall signs of sepsis are present and for patients with a comorbidity such as diabetes, valvular heart disease, or immunodeficiency.
Anal and rectal traumas are relatively rare (with the exception of iatrogenic damage) due to the anatomical position of the anorectum. The anal canal is injured more frequently due to its relatively superficial position, but injuries involving the extraperitoneal rectum, although more rare, tend to be much more severe and may affect the surrounding organs. Intraperitoneal rectal injury is associated with bleeding or perforation and may lead to peritonitis and diffuse contamination of the abdominal cavity. The decisive factor is the early detection of the injury and early initiation of treatment. The first step in surgical treatment of severe anorectal injury is the control of massive bleeding and volume resuscitation. The aim of the surgery is to preserve life, control infections and to preserve the patients anal continence and evacuation function. Key words: anorectal trauma - aetiology - surgical treatment.
