Peritonitis - spontaneous

Definition:

Peritonitis is the inflammation of the peritoneum, which is the membrane that lines the abdominal wall and covers the abdominal organs. Spontaneous peritonitis is an infection that occurs as a complication of ascites (a collection of fluid in the peritoneal cavity), which is usually related to liver or kidney failure.


Alternative Names:
Spontaneous bacterial peritonitis (SBP)
Causes, incidence, and risk factors:


Most cases of bacterial peritonitis occur:

  • When fluid accumulates in the peritoneal cavity (ascites) because of chronic liver disease.
  • In renal (kidney) failure patients undergoing peritoneal dialysis. In these patients, the cause of spontaneous peritonitis is infection that spreads to the peritoneal fluid, usually from a contaminated peritoneal dialysis catheter.

Risk factors for liver disease include alcoholic cirrhosis and other diseases that lead to cirrhosis, such as viral hepatitis (Hepatitis B or C).
