Peritonitis - spontaneous
Peritonitis is inflammation of the peritoneum, the thin tissue that lines the inner wall of the abdomen and covers most of the abdominal organs.
Spontaneous bacterial peritonitis (SBP)
Causes, incidence, and risk factors
Spontaneous peritonitis is usually caused by infection of ascites, a collection of fluid in the peritoneal cavity. This usually occurs from liver or kidney failure.
Spontaneous peritonitis also occurs in patients who are on dialysis for kidney failure.
Other symptoms include:
Signs and tests
Tests will be done to check for infection and rule out other causes of abdominal pain:
Treatment depends on the cause of the peritonitis.
- Surgery may be needed if peritonitis is caused by a foreign object, such as a catheter used in peritoneal dialysis.
- Antibiotics may control infection in cases of spontaneous peritonitis with liver or kidney disease.
- Intravenous therapy can treat dehydration.
The infection can usually be treated. However, kidney or liver disease may limit recovery.
Calling your health care provider
Call your health care provider if you have symptoms of peritonitis. This can quickly become an emergency situation.
Patients with peritoneal catheters should be treated with sterile techniques. In cases of liver failure, antibiotics may help prevent peritonitis from coming back.
