Study Notes
General Pathology: Diseases of the Peritoneum and Gastrointestinal Vascularization
- This presentation covers diseases of the peritoneum and gastrointestinal vascularization.
- Learning objectives include the clinical presentation of patients with these conditions, and the pathophysiology of peritonitis and intestinal ischemia.
Physiopathology of Peritonitis
- Translinphatic absorption clears bacteria through respiratory movements, creating a subdiaphragmatic vacuum. This movement drives peritoneal fluid and absorbs up to 60% of the bacterial inoculum.
- Neutrophils, the predominant cells in the peritoneal cavity, are responsible for phagocytosis.
- Peritoneal cavity cells include 50% lymphocytes, 40% macrophages, and 10% eosinophils. This cell population develops an inflammatory response within 3-4 hours.
- 30% of microorganisms are phagocytosed.
- Fibrotic compartmentalization often occurs locally.
Types of Bacterial Peritonitis
- Primary peritonitis:
- Spontaneous bacterial peritonitis
- Peritoneal dialysis system infection
- Primary peritonitis in children
- Secondary peritonitis:
- Local
- Disseminated
- Tertiary peritonitis
Diagnosis of Peritonitis
- Symptomatology: Pain, fever, nausea, intestinal arrest, and systemic inflammatory response syndrome (SIRS) symptoms.
- Exploration: Muscular tenderness, and specific signs like Blumberg, Murphy, and Rovsing.
- Complementary studies: Blood tests, cultures, and imaging studies.
Intestinal Vascular Disease
- Acute ischemia:
- Occlusive: Arterial—emboli, thrombosis; Venous—thrombosis, strangulation.
- Non-occlusive: Arterial—vasoconstriction, Venous—vasoconstriction
- Chronic ischemia: Atherosclerosis is the primary cause. Note: Additional causes are not mentioned.
