DefinitionPeritonitis is an inflammation or infection of the peritoneum. The peritoneum is a thin tissue lining that covers the inside of the abdominal cavity. It also covers the outside of the intestines and other abdominal organs.There are several types:
- Peritoneal dialysis-related
- Primary peritonitis—Occurs when there is a buildup of fluid in the abdomen. This is called ascites . It is caused by health conditions, such as cirrhosis (chronic liver disease).
- Secondary peritonitis—Caused by bacteria that enter the abdominal cavity. Can be due to an injury or a condition, such as a ruptured appendix.
- Dialysis-related peritonitis—Caused by bacteria that enter the peritoneal cavity during or after peritoneal dialysis (a treatment for kidney disease).
