Abscess

Introduction Abscess is a localized pus accumulation in tissue, organ or body cavity due to necrosis and liquefaction of the diseased tissue during acute infection. There is a complete pus wall around it. The common pathogen is Staphylococcus aureus. The abscess can be caused by an acute suppurative infection, or by a pathogen of a distant source of infection through the bloodstream or lymphatic vessels. It is often caused by necrosis and dissolution of inflammatory tissue under the action of toxins or enzymes produced by bacteria, forming a abscess cavity, exudate in the cavity, necrotic tissue, pus cells and bacteria to form a pus.

Cause

The common pathogen is Staphylococcus aureus. The plasma coagulase produced by the bacteria converts the exuded fibrinogen into cellulose, preventing the spread of pathogenic bacteria. Staphylococcus aureus also has a laminin receptor, which can form migratory abscesses at a distance through the vessel wall.

1. Shallow part: Abscess manifests as local redness, swelling, heat, pain and tenderness, and then fluctuates.

2. Deep: The abscess is a local diffuse swelling, pain and tenderness, and the fluctuation is not obvious. The puncture can be taken out by the test puncture, and it can also be used as an ultrasound consultation.

Differential diagnosis

Mainly distinguish the site of the abscess. When the abscess spreads out, complications such as ulcers, sinus and fistula can often be formed. Suppurative inflammation of the skin, mucous membrane or synovial membrane of the joint may form a localized ulcer due to local tissue necrosis and disintegration. Deep tissue abscesses can be worn through the body surface or natural tubing to form a sinus. The abscess around the anorectal rectum penetrates into the skin and forms an anal purulent sinus; if the rectal wall is penetrated inward at the same time, the intestinal cavity is connected with the skin of the body surface, and a purulent fistula is formed.
