Signalment
Description
Peritonitis is defined as the inflammation of the peritoneum. Peritonitis can be septic or non-septic. Septic peritonitis results from free bacteria in the peritoneal cavity, caused by perforating injuries to the gastrointestnal tract due to foreign bodies, necrosis secondary to obstruction or intussusception. Non-septic, also known as chemical peritonitis, may be the result of leakage of bile, urine or pancreatic enzymes. However, non-septic peritonitis can cause septic peritonitis, for example cases where septic urine is present.
Diagnosis
Clinical Signs
- Depressed
- Tachycardia
- Tachypnoea
- Pale, cyanotic or muddly mucous membranes
- Hypothermia or hyperthermia
- Abdominal pain
Laboratory Tests
Haematology
Biochemistry
- Significan leucocytosis or leucopaenia
- Hypoglycaemia
- Increased lactate concentration
Other Tests
- Abdominal fluid collected for laboartory analysis via abdominocentesis. The fluid should be stained for intracellular bacteria and assessed for:
- amylase and lipase for pancreatitis
- bile for biliary leak
- creatinine for urine
- glucose (2.8 mmol/l) and lactate (>5.5 mmol/l) for sepsis
Diagnostic Imaging
Radiography
- Abdominal radiography may reveal free gas in the abdomen. This is highly suggestive of peritonitis
- Thoracic radiograph should be assessed for signs of metastatic disease.
Histopathology
Treatment
- It is vital to identify cases which require emergency surgical intervention. Any of the following is a major indication:
- positive for intracellular bacteria.
- free gas visible in the abdominal radiograph.
- presence of penetrating injuries in the abdomen.
