peritonitis

(pĕr'ĭtənī`tĭs), acute or chronic inflammation of the peritoneumperitoneum
, multilayered membrane which lines the abdominal cavity, and supports and covers the organs within it. The part of the membrane that lines the abdominal cavity is called the parietal peritoneum.

, the membrane that lines the abdominal cavity and surrounds the internal organs. It is caused by invasion of bacterial agents or irritant foreign matter during rupture of an internal organ, by spreading infection from the female genital tract, by penetrating injuries of the abdominal wall, by dissemination of infections through the blood and lymphatic channels, or by accidental pollution during surgery. Typically, peritonitis is a serious complication of another abdominal disorder, such as appendicitis, ulcers, colitis, or rupture of the gall bladder. Severe abdominal pain, vomiting, prostration, and high fever are predominant symptoms. Treatment includes antibiotic therapy and the identification and elimination of the cause of the infection.

Peritonitis

 

inflammation of the peritoneum. Peritonitis can result from a variety of diseases and traumas of the abdominal organs, including acute appendicitis, perforating gastric or duodenal ulcers, and intestinal obstructions; it can also develop from surgical complications. The causative agents are either cocci or Escherichia coli; when peritonitis is caused by the latter, for example, in perforating appendicitis or perforation of an intestinal tumor, the course of the inflammation can be very severe.

Depending on the distribution of the inflammatory process, peritonitis can be circumscribed, that is, confined to some portion of the abdominal cavity, or diffuse. The clinical picture of acute abdomen consists of the symptoms of diffuse peritonitis— namely, sharp abdominal pain, vomiting, retention of stools and gases in a condition called adynamic ileus, local or diffuse rigidity of the abdominal muscles, marked tenderness upon palpation of the anterior abdominal wall, and systemic intoxication as evidenced by fever, increased heart rate, and neutrophilic leukocytosis.

Chronic peritonitis, which is usually encountered in tuberculosis, is rare. The exudative form is attended by an accumulation of exudate in the abdominal cavity, while the adhesive form is marked by the appearance of massive adhesions. Serous, purulent, fibrocaseous, and septic peritonites are distinguished according to the type of exudate. Peritonitis is treated surgically and can be prevented by prompt diagnosis and treatment of acute abdominal conditions.

Peritonitis

 

Definition

Peritonitis is an inflammation of the membrane which lines the inside of the abdomen and all of the internal organs. This membrane is called the peritoneum.

Description

Peritonitis may be primary (meaning that it occurs spontaneously, and not as the result of some other medical problem) or secondary (meaning that it results from some other condition). It is most often due to infection by bacteria, but may also be due to some kind of a chemical irritant (such as spillage of acid from the stomach, bile from the gall bladder and biliary tract, or enzymes from the pancreas during the illness called pancreatitis). Peritonitis has even been seen in patients who develop a reaction to the cornstarch used to powder gloves worn during surgery. Peritonitis with no evidence of bacteria, chemical irritant, or foreign body has occurred in such diseases as systemic lupus erythematosus, porphyria, and familial Mediterranean fever. When the peritoneum is contaminated by blood, the blood can both irritate the peritoneum and serve as a source of bacteria to cause an infection. Blood may leak into the abdomen due to a burst tubal pregnancy, an injury, or bleeding after surgery.

Causes and symptoms

Primary peritonitis usually occurs in people who have an accumulation of fluid in their abdomens (ascites). Ascites is a common complication of severe cirrhosis of the liver (a disease in which the liver grows increasingly scarred and dysfunctional). The fluid that accumulates creates a good environment for the growth of bacteria.Secondary peritonitis most commonly occurs when some other medical condition causes bacteria to spill into the abdominal cavity. Bacteria are normal residents of a healthy intestine, but they should have no way to escape and enter the abdomen, where they could cause an infection. Bacteria can infect the peritoneum due to conditions in which a hole (perforation) develops in the stomach (due to an ulcer eating its way through the stomach wall) or intestine (due to a large number of causes, including a ruptured appendix or a ruptured diverticulum). Bacteria can infect the peritoneum due to a severe case of pelvic inflammatory disease (a massive infection of the female organs, including the uterus and fallopian tubes). Bacteria can also escape into the abdominal cavity due to an injury that causes the intestine to burst, or an injury to an internal organ which bleeds into the abdominal cavity.Symptoms of peritonitis include fever and abdominal pain. An acutely ill patient usually tries to lie very still, because any amount of movement causes excruciating pain. Often, the patient lies with the knees bent, to decrease strain on the tender peritoneum. There is often nausea and vomiting. The usual sounds made by the active intestine and heard during examination with a stethoscope will be absent, because the intestine usually stops functioning. The abdomen may be rigid and boardlike. Accumulations of fluid will be notable in primary peritonitis due to ascites. Other signs and symptoms of the underlying cause of secondary peritonitis may be present.

Diagnosis

A diagnosis of peritonitis is usually based on symptoms. Discovering the underlying reason for the peritonitis, however, may require some work. A blood sample will be drawn in order to determine the white blood cell count. Because white blood cells are produced by the body in an effort to combat foreign invaders, the white blood cell count will be elevated in the case of an infection. A long, thin needle can be used to take a sample of fluid from the abdomen in an effort to diagnose primary peritonitis. The types of immune cells present are usually characteristic in this form of peritonitis. X-ray films may be taken if there is some suspicion that a perforation exists. In the case of a perforation, air will have escaped into the abdomen and will be visible on the picture. When a cause for peritonitis cannot be found, an open exploratory operation on the abdomen (laparotomy) is considered to be a crucial diagnostic procedure, and at the same time provides the opportunity to begin treatment.

Treatment

Treatment depends on the source of the peritonitis, but an emergency laparotomy is usually performed. Any perforated or damaged organ is usually repaired at this time. If a clear diagnosis of pelvic inflammatory disease or pancreatitis can be made, however, surgery is not usually performed. Peritonitis from any cause is treated with antibiotics given through a needle in the vein, along with fluids to prevent dehydration.

Prognosis

Prognosis for untreated peritonitis is poor, usually resulting in death. With treatment, the prognosis is variable, dependent on the underlying cause.

Prevention

There is no way to prevent peritonitis, since the diseases it accompanies are usually not under the voluntary control of an individual. However, prompt treatment can prevent complications.

peritonitis

 [per″i-to-ni´tis] inflammation of the peritoneum. Acute Peritonitis. Acute peritonitis may be produced by inflammation of abdominal organs, by irritating substances from a perforated gallbladder or gastric ulcer, by rupture of a cyst, or by irritation from blood, as in cases of internal bleeding.Symptoms and Diagnosis. Immediate and intense pain is felt at the site of infection, followed usually by fever, vomiting, and extreme weakness. The abdomen becomes rigid and sensitive to the touch. The patient may suffer mental confusion, fever, prostration, or shock. Although antibiotics have greatly reduced the mortality rate of acute peritonitis, the infection should be treated and controlled immediately; it can be fatal if neglected.
Diagnosis is based on manual examination, x-ray films, and blood tests.
Treatment. The basic treatment for acute peritonitis is a combination of surgery, antibiotics, and other measures. The peritoneal cavity often must be opened and the toxic material removed. The original source of infection, such as an inflamed appendix, may have to be removed, or an abscess caused by the peritonitis may have to be drained. Antibiotics are used to fight the infection itself.
The patient usually takes nothing by mouth. Fluids are given intravenously. Narcotics and sedatives are often used to relieve pain and ensure rest. Treatment may also include blood transfusions and suction through a nasogastric tube to relieve abdominal pressure and to prevent accumulation of gas in the intestines.
Chronic Peritonitis. The chronic form of this disease is comparatively rare, and is often associated with tuberculosis. Less frequently it may result from longstanding irritation caused by the presence in the abdomen of a foreign body such as gunshot.
In general, symptoms of chronic peritonitis are milder than those of acute peritonitis. Symptoms of tuberculous peritonitis are abdominal pain, low-grade fever, constipation, and general ill health, including loss of weight and appetite. Treatment depends on the underlying cause and the severity of the condition.
Peritonitis. Infection spreads via lymphatics to peritoneum; formation of a pelvic abscess may occur. From McKinney et al., 2000.
adhesive peritonitis peritonitis characterized by adhesions between adjacent serous structures.bile peritonitis (biliary peritonitis) that due to the presence of bile in the peritoneum; choleperitoneum.gas peritonitis peritonitis with the accumulation of gas in the peritoneum.septic peritonitis peritonitis caused by a pyogenic microorganism.silent peritonitis asymptomatic peritonitis.
