Primary peritonitis is the most severe type of peritonitis, characterized by widespread inflammation of the abdominal cavity and abdominal wall due to a direct invasion of a foreign substance or an abscess forming inside the abdomen. Examples include:
Penetrating injuries from a cut or stab wound.
Perforated viscus from a perforation.
Intra-abdominal infections due to bacteria or fungi entering the abdomen.
Secondary peritonitis develops when an existing medical condition, such as a perforated appendix, becomes infected. This is more common in patients with compromised immune systems. Examples include:
Appendiceal abscess.
Diverticulitis.
Inflammatory bowel disease.
Tertiary peritonitis is the most complex and severe type of peritonitis, often caused by bacteria entering a leak or tear in the abdomen. This is more common in patients with cancer or diabetes. Examples include:
Cancer-related perforation.
Leakage from a surgical site.
Sepsis caused by a leaking intra-abdominal abscess.
Here's a breakdown of the key differences:
| Peritonitis Type | Cause | Location | Symptoms | Treatment |
|---|---|---|---|---|
| Primary | Direct invasion | Abdominal cavity and wall | Widespread inflammation, pain, nausea, vomiting | Surgery, antibiotics |
| Secondary | Existing medical condition | Within abdomen | Fever, nausea, vomiting, abdominal pain | Antibiotics, surgical intervention |
| Tertiary | Bacteria entering a leak | Within abdomen | Fever, severe pain, signs of sepsis | Antibiotics, surgical intervention, supportive care |
