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)
Spontaneous peritonitis is usually caused by infection of ascites, a collection of fluid in the peritoneal cavity. This usually occurs from severe liver or kidney disease.
Spontaneous peritonitis also occurs in patients who are on peritoneal dialysis for kidney failure.
Peritonitis may also occur due to inflammation, infection, or injury of the intestines. Examples include appendicitis or diverticulitis.
Other symptoms include:
Tests will be done to check for infection and rule out other causes of abdominal pain:
Treatment depends on the cause of the peritonitis.
The infection can usually be treated. However, kidney or liver disease may limit recovery.
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. Antibiotics may be used to prevent peritonitis if you have acute gastrointestinal bleeding due to certain health conditions.
