Peritonitis

Peritonitis is an inflammation of the peritoneum caused by physical, chemical, or bacterial irritation. According to its mechanism, it can be divided into primary peritonitis and secondary peritonitis. Primary peritonitis: Refers to peritonitis caused by pathogens entering the abdominal cavity via the bloodstream, lymphatic system, intestinal wall, or female reproductive tract, without an obvious primary infectious lesion within the abdominal cavity. Secondary peritonitis: This is the most common clinical type, secondary to infection of intra-abdominal organs, perforation or rupture of hollow organs, etc. Patients with peritonitis mainly present with abdominal pain, abdominal distension, abdominal tenderness, abdominal muscle rigidity, rebound tenderness, nausea, vomiting, and fever. In severe cases, it can lead to a drop in blood pressure and systemic toxic reactions. If the condition is delayed and not treated promptly, it can lead to adhesive intestinal obstruction, toxic shock, sepsis, and abscesses, threatening the patient's life.
