Abscesses

Abscesses are collections of pus in limited tissue areas, usually caused by a bacterial infection. Symptoms include localized pain, tenderness, warmth and swelling (if the abscesses are close to the skin layers) or other physical complaints (if abscesses are deep). imaging procedures are often necessary for diagnosing deep abscesses. Treatment consists of surgical Abszessspaltung and Drainage and often antibiotics.

Etiology A variety of microorganisms can cause abscesses, but the most common Staphylococcus aureus organisms are able to penetrate into the tissue by direct implantation (for. Example, penetrating trauma with a contaminated object) spreading an established, contiguous spread of infection via lymphatic or hematogenous routes of a distant range. Immigration from a place where there is a local Flora, into an adjacent, normally sterile area because natural obstacles were disturbed (eg., By perforation of an abdominal viscera, causing an intra-abdominal abscess) abscesses can of a cellulitis or emanating from tissues affected by accumulation of leukocytes. A progressive tissue dissection by pus or necrosis of surrounding cells leads to expansion of the abscess. Well vascularized connective tissue can then surrounded the necrotic tissue, leukocytes and debris to delineate the abscess and to limit its further spread. Among the predisposing factors for the formation of abscesses include: Impaired host defense mechanisms (. Eg, impaired leukocyte Defense) The presence of foreign bodies, obstruction of the normal drainage (for example in the urinary, biliary or airways) tissue ischemia or necrosis hematoma or excessive fluid accumulation in tissue trauma symptoms and complaints Clinical symptoms of cutaneous and subcutaneous abscesses are pain, warmth, swelling, tenderness and redness. If superficial abscesses are about spontaneously break out, the skin may be thin due to the underlying pus over the center of the abscess, sometimes white or appear yellow (as a reference). Fever may be present, particularly at a local cellulite. In deep abscesses local pain and tension as well as systemic symptoms, especially fever, and anorexia, weight loss and fatigue are typical. Some abscesses manifest themselves primarily by organ dysfunction (eg. As hemiplegia due to a brain abscess). Complications of abscesses include bacteremic dissemination rupture into neighboring tissue bleeding from vessels eroded by inflammation Impaired function of a vital organ inanition due to anorexia and increased metabolic needs diagnosis Clinical evaluation Sometimes ultrasound, CT or MRI Cutaneous and subcutaneous abscesses are diagnosed by physical examination. Diagnosis deep abscesses often requires imaging techniques. Ultrasound is noninvasive and shows many Weichteilabszesse on; CT is usually sufficient, although an MRI is more sensitive in general. Therapy Surgical drainage Sometimes antibiotics Superficial abscesses can be treated by heat therapy and oral antibiotics. for a cure usually is nevertheless a Abszessspaltung and Drainage required. Minor skin abscesses can possibly only require an incision and drainage. All pus, necrotic tissue and Débris should be removed. It may be necessary to fill in the abscess cavity with gauze or through the insertion of a drainage. Predisposing factors such. As a disturbance of the natural drainage or the presence of a foreign body requiring their correction. Deep abscesses can be appropriately by percutaneous puncture (typically performed by ultrasound or CT) sometimes discharged; this method often avoids the need for open surgical drainage. Spontaneous rupture and drainage may occur and sometimes lead to the formation of chronic draining sinuses. Without draining an abscess forms occasionally slowly by proteolytic digestion of the pus back and forms a sterile liquid which is reabsorbed into the blood stream. Incomplete absorption can lead to a cystic structure surrounded by a fibrous wall, which can calcify. Systemic antimicrobial drugs are indicated as adjunctive therapy as follows: If the abscess is deep (. Eg intra-abdominal) If there are multiple abscesses If a substantial surrounding cellulite exists Perhaps if the size is> 2 cm Antimicrobial drugs are usually ineffective without drainage. Empirical antimicrobial therapy depends on the location and the possible pathogens. A Gram stain, culture and sensitivity results may point the way for antimicrobial therapy. Important points Cutaneous and subcutaneous abscesses are diagnosed clinically; deeper abscesses often require imaging techniques. Normally abscess is drained by cutting or sometimes by puncture. Antibiotics should be used if abscesses are deep or are surrounded by significant cellulite.
