Your peritoneum is the tissue that lines your abdominal wall and covers most of the organs in your abdomen. A liquid, peritoneal fluid, lubricates the surface of this tissue.
Disorders of the peritoneum are not common. They include
- Peritonitis - an inflammation of the peritoneum
- Cancer
- Complications from peritoneal dialysis
Your doctor may use imaging tests or lab tests to analyze the peritoneal fluid to diagnose the problem. Treatment of peritoneal disorders depends on the cause.
