Primary Peritoniitis

Decent Essays

The abdominal cavity is the largest hollow space in the human body and contains the liver, pancreas, spleen, kidneys and adrenal glands, and the digestive tract. The cavity is lined by a thin, silk-like membrane called the peritoneum which covers the inside wall of the abdominal cavity and every organ or structure contained in it. A common affliction of the abdominal cavity is peritonitis, which is an inflammation of the peritoneum membrane caused by the introduction of a fungal or bacterial infection in an otherwise sterile environment. The infection is often caused by an abdominal injury that creates a rupture (perforation) within the abdominal cavity, or may arise from a complication of an underlying medical condition. The infection can …show more content…

Primary peritonitis is an infection that develops in the abdominal (ascitic) fluid of the peritoneal cavity. It is mostly seen in patients suffering from advanced liver disease with cirrhosis, where abdominal fluid builds up (ascites) in the peritoneal cavity and may become infected. Although rare in the absence of a perforation, there are many underlying conditions that can contribute to the growth of bacteria in the ascitic fluid. This type is called spontaneous bacterial peritonitis and is the most common reason of primary peritonitis. Factors that increase risk of primary peritonitis include medical procedures like peritoneal dialysis, medical conditions such as cirrhosis, kidney failure, and heart disease, and patient history of peritonitis. However, in most cases the type of infection that develops is secondary peritonitis, which is usually caused by an infection that has spread from the digestive tract after trauma or perforation of the abdominal viscera that allows infectious organisms to contaminate the sterile environment of the peritoneal cavity. Most common causes of secondary peritonitis include injury or trauma to the peritoneum, a ruptured appendix, or stomach ulcer, digestive diseases such as Crohn’s Disease, and diverticulitis, perforations of the stomach, or intestines, and abdominal trauma such as injury from a knife or gunshot wound. Both types of peritonitis are life threatening, and when left untreated can enter into the bloodstream spreading the infection throughout the entire body leading to shock and organ
