What is the pathophysiology of peritonitis?

Spontaneous bacterial peritonitis (SBP) is an acute bacterial infection of ascitic fluid. Contamination of the peritoneal cavity is thought to result from translocation of bacteria across the gut wall or mesenteric lymphatics and, less frequently, via hematogenous seeding in the presence of bacteremia.

What is appendicitis with localized peritonitis?

Acute appendicitis is one of the most common causes of the acute abdomen, occurring at all ages. Inflammation of the appendiceal wall leads to ischemia, necrosis, and eventually perforation, which may result in a localized abscess or generalized peritonitis.

What is the most common cause of peritonitis?

Peritonitis is usually caused by infection from bacteria or fungi. Left untreated, peritonitis can rapidly spread into the blood (sepsis) and to other organs, resulting in multiple organ failure and death.

Can a abdominal ultrasound show signs of appendicitis?

Abdominal ultrasound creates images of the appendix and can show signs of inflammation, a burst appendix, a blockage in the appendiceal lumen, and other sources of abdominal pain. Ultrasound is the first imaging test performed for suspected appendicitis in infants, children, young adults, and pregnant women.

Can a simple case of appendicitis progress to perforation?

Together these observations suggest that the underlying pathophysiologic processes are different and that simple appendicitis does not always progress to perforation. Furthermore, some cases of simple acute appendicitis may resolve spontaneously or with antibiotic therapy, and recurrent disease is remotely possible.

When does continuing education activity appendicitis occur?

Continuing Education Activity Appendicitis is the inflammation of the vermiform appendix. It typically presents acutely, within 24 hours of onset, but can also present as a more chronic condition. Classically, appendicitis presents with initial generalized or periumbilical abdominal pain that later localizes to the right lower quadrant.
