Peritonitis - spontaneous bacterialSpontaneous bacterial peritonitis (SBP); Ascites - peritonitis; Cirrhosis - peritonitis
The peritoneum is the thin tissue that lines the inner wall of the abdomen and covers most of the organs. Peritonitis is present when this tissue becomes inflamed or infected.
Spontaneous bacterial peritonitis (SBP) is present when this tissue becomes infected and there is no clear cause.
SBP is most often caused by infection in fluid that collects in the peritoneal cavity (ascites). The fluid buildup often occurs with advanced liver or kidney disease.
Ascites is the build-up of fluid in the space between the lining of the abdomen and abdominal organs.
Risk factors for liver disease include:
- Very heavy alcohol use
- Chronic hepatitis B or hepatitis C
Hepatitis B is irritation and swelling (inflammation) of the liver due to infection with the hepatitis B virus (HBV). Other types of viral hepatitis ...
- Other diseases that lead to cirrhosis
SBP also occurs in people who are on peritoneal dialysis for kidney failure.
Peritonitis may have other causes. These include infection from other organs or leakage of enzymes or other toxins into the abdomen.

Exams and Tests
Tests will be done to check for infection and other causes of abdominal pain:
- Blood culture
- White blood cell count in a sample of peritoneal fluid
- Chemical examination of peritoneal fluid
- Culture of peritoneal fluid
- CT scan or ultrasound of the abdomen
Treatment depends on the cause of the SBP.

- Surgery may be needed if SBP is caused by a foreign object, such as a catheter used in peritoneal dialysis.
- Antibiotics to control infection.
- Fluids given through the veins.
You will need to stay in the hospital so health care providers can rule out other causes such as a ruptured appendix and diverticulitis.
Diverticula are small, bulging sacs or pouches that form on the inner wall of the intestine. Diverticulitis occurs when these pouches become inflame...
In most cases, the infection can be treated. However, kidney or liver disease may limit recovery.
The term "liver disease" applies to many conditions that stop the liver from working or prevent it from functioning well. Abdominal pain, yellowing ...
Complications may include:
- Loss of brain function occurs when the liver is unable to remove toxins from the blood.
- Kidney problem caused by liver failure.
When to Contact a Medical Professional
Call your provider if you have symptoms of peritonitis. This can be a medical emergency situation.
Steps should be taken to prevent infection in people with peritoneal catheters.
Continuous antibiotics may be used:
- To prevent peritonitis from coming back in people with liver failure
- To prevent peritonitis in people who have acute gastrointestinal bleeding due to other conditions
