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.
