Overview

Secondary peritonitis has to be differentiated from spontaneous bacterial peritonitis which is also seen in cirrhotics and also from other causes of peritonitis.

Differential Diagnosis

Differentiating secondary peritonitis from spontaneous bacterial peritonitis
Characteristic Spontaneous bacterial peritonitis Secondary peritonitis
Presentaion
  • Similar presentation but insidious onset unlike rapid onset in SBP
Microorganism
  • Polymicrobial involvement is common
  • Identifiable source of intra-abdominal infection, with or without perforation (surgically treatable source)[1]
Diagnostic criteria SBP is diagnosed in the presence of:[2] Diagnosed in the presence of
Follow-up paracentesis
Differentiating Secondary peritonitis from other causes of peritonitis
Disease Prominent clinical findings Lab tests Tratment
Primary peritonitis Spontaneous bacterial peritonitis
Tuberculous peritonitis
Continuous Ambulatory Peritoneal Dialysis (CAPD peritonitis)
Secondary peritonitis Acute bacterial secondary peritonitis
Biliary peritonitis
Tertiary peritonitis
Familial Mediterranean fever (periodic peritonitis, familial paroxysmal polyserositis)
  • Colchicine prevents but does not treat acute attacks.
Granulomatous peritonitis
  • Diagnosed by the demonstration of diagnostic Maltese cross pattern of starch particles.
Sclerosing encapsulating peritonitis
Intraperitoneal abscesses
  • Diagnosed best by CT scan of the abdomen.
  • Treatment consists of prompt and complete CT or US guided drainage of the abscess, control of the primary cause, and adjunctive use of effective antibiotics. Open drainage is reserved for abscesses for which percutaneous drainage is inappropriate or unsuccessful.
Peritoneal mesothelioma
peritoneal carcinomatosis
