Peritonitis - spontaneous bacterial
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.
Spontaneous bacterial peritonitis (SBP); Ascites - peritonitis; Cirrhosis - peritonitis
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.
