Overview
Overview
With treatment, patients usually do well. Without treatment, the outcome is usually poor. However, in some cases, patients do poorly even with prompt and appropriate treatment.
Natural History
Secondary peritonitis is the initial phase of infection after intestinal perforation which can progress to abscess, if left untreated. Severe abdominal infections are invariably progress to a high level of sepsis, endotoxin production and systemic inflammatory response syndrome (SIRS), which often results in multiple organ failure.[1][2]
Complications
- Tertiary peritonitis usually follows operative attempts to treat secondary peritonitis and is almost always associated with a systemic inflammatory response. It is a persistent/recurrent infection with organisms of low virulence.
- Surgical site infection and delayed wound healing- Depends on the degree of contamination. Measures taken to prevent postoperative infections such as peri-operative, systemic antibiotics, and lavage of the wound would not help to prevent this complication. In such instances, the wound should be kept open, and treated with wet-to-dry dressing several times a day. It occurs in 5-15% of patients.
- Intra-abdominal abscess
- Intraperitoneal adhesions, leading to bowel obstruction
- Septic shock
Prognosis
Factors affecting prognosis are:
- Age
- Blood pressure
- Cause of infection
- Site of origin of peritonitis
- Number of organs involved in multi-organ-failure (MOF)
- Pre-operative organ failure
- Presence of metabolic acidosis
- Serum albumin
- New York Heart Association cardiac function status
- Malnutrition
- Malignoma
- Fecal peritonitis
- Immunosuppression
