Abstract: Spontaneous bacterial peritonitis (SBP) is a common and potential life-threatening complication
in patients with hepatic cirrhosis ascites. It is caused by ascites infection without the cure of abdominal
surgery. The incidence of SBP was 30% in patients with hepatic cirrhosis ascites, and it is a sign of severe
liver dysfunction. The pathogenesis of SBP includes the intestinal bacterial overgrowth, intestinal mucosal
permeability changes, bacterial translocation and the low immunity of the body. This article reviewed the
research progress of the associated risk factors of SBP in liver cirrhosis in recent years.
