Peritonitis is a life-threatening condition that requires prompt medical treatment. It is caused by the inflammation of the peritoneum, the lining of the abdominal wall and organs. Patients with peritonitis often experience abdominal pain, swelling, fever, and weight loss. The condition can lead to intestinal paralysis, resulting in a loss of bowel sounds. However, in some cases of intestinal obstruction, hyperactive bowel sounds may be present. The presence of hyperactive bowel sounds in peritonitis patients could indicate early mechanical bowel obstruction, where hyperactive peristaltic waves increase the frequency and force of bowel sounds.

Peritonitis is inflammation of the abdominal membranes, often due to bacterial infection
Peritonitis is a severe inflammation of the peritoneum, the thin membrane that lines the abdomen and covers the abdominal organs. It is most commonly caused by bacterial infection, either from a primary infection in the peritoneum or, more frequently, when a bacterial infection in a nearby organ spreads to the peritoneum.
The abdominal organs, such as the stomach and liver, are wrapped in the peritoneum, a thin but tough membrane. The abdominal walls are also lined with a layer of peritoneum, called the parietal peritoneum. A protective layer of fat contained in a membrane (the omentum) sits between the organs and the abdominal wall. Lubricating fluid allows all these membranes to slide smoothly over each other. The main function of the peritoneum is to permit free movement of the internal organs during digestion.
Bacterial infections can enter the peritoneal cavity in several ways. For example, bacteria can enter the abdominal cavity through a stab wound or a surgical wound. Peritonitis can also occur when bacteria enter the peritoneal cavity during peritoneal dialysis or intra-peritoneal chemotherapy. In addition, bacteria may enter the peritoneal cavity if a person is receiving nutrition through a feeding tube.
Another cause of peritonitis is when fluid from nearby organs leaks into the peritoneum, causing chemical peritonitis. This can happen when a person has a condition that damages organs close to the peritoneum, allowing infected fluid to seep into the peritoneum. This can be caused by several conditions, including perforated ulcer, perforated bowel, a burst appendix, perforated gall bladder, and pancreatitis.
Peritonitis is a medical emergency that can cause life-threatening complications if not treated promptly. Treatment options include hospitalisation, antibiotics, intravenous fluids, pain medication, and surgery.

Peritonitis causes abdominal rigidity, which can lead to absent bowel sounds
Peritonitis is the inflammation of the abdominal membranes, which are the lining of the inner abdominal wall and the covering of the abdominal organs. It is most commonly caused by bacterial infection and can be life-threatening if not treated promptly. The main manifestations of peritonitis are acute abdominal pain, abdominal tenderness, abdominal guarding, and rigidity, which are exacerbated by moving the peritoneum. This rigidity is often present, especially in generalized peritonitis, and is the most specific exam finding for diagnosing peritonitis. It is caused by the irritation or inflammation of the parietal peritoneum, which stimulates the pain fibres and creates symptoms of localized pain and tenderness.
Abdominal rigidity can lead to absent bowel sounds, which is a common finding in patients with peritonitis. The abdomen is often distended, with hypoactive-to-absent bowel sounds, reflecting a generalized ileus. Ileus, or intestinal paralysis, can cause nausea, vomiting, and bloating, as well as reduced or no passage of abdominal gas and bowel sounds. This can be a result of the infection stopping the normal movements of the intestines (peristalsis). Peritonitis can also lead to abdominal masses, which are related to the underlying organs. These masses should be examined for peristalsis, as they may represent dilated bowel.
The diagnosis of peritonitis is usually clinical and based on examination, blood tests, and medical imaging. A patient's history should include recent abdominal surgery, previous episodes of peritonitis, travel history, use of immunosuppressive agents, and the presence of diseases that may predispose to intra-abdominal infections. Treatment options include hospitalization, antibiotics, and surgery.

Peritonitis can result from abdominal trauma, ingestion of sharp objects, or surgery
Peritonitis is an inflammation of the localized or generalized peritoneum, the lining of the inner wall of the abdomen and covering of the abdominal organs. It is a serious condition that can lead to death within a few days if left untreated. The main symptoms of peritonitis include acute abdominal pain, abdominal tenderness, and rigidity, which are exacerbated by movement. Other symptoms include swelling of the abdomen, fever, weight loss, and abdominal guarding.
Surgery can also be a cause of peritonitis, particularly abdominal surgery. This is because the abdominal cavity is a sterile environment, and any disruption to this, such as during surgery, can introduce microorganisms that can cause infection and inflammation. In addition, surgery can also cause iatrogenic injuries, such as perforation of the intestinal tract, which can lead to peritonitis.
Furthermore, peritonitis can also occur as a complication of other medical procedures, such as endoscopy or catheterization, which can also cause perforation of the intestinal tract. Those who have undergone abdominal surgery are also at risk of developing ileus paralyticus, or intestinal paralysis, which can cause abdominal pain, nausea, vomiting, and bloating, further increasing the risk of peritonitis.
Overall, peritonitis is a serious condition that can have various causes, including abdominal trauma, ingestion of sharp objects, and surgery. Early diagnosis and treatment are crucial to prevent complications and potential death.

Bowel obstruction or ileus can cause hyperactive bowel sounds
Peritonitis is the inflammation of the membranes of the abdominal wall and organs, most commonly due to bacterial infection. It is life-threatening if not treated promptly. The infection stops the normal movements of the intestines, causing the body to quickly become dehydrated, and important chemicals called electrolytes are disturbed.
Hyperactive bowel sounds mean there is an increase in intestinal activity, which may happen with diarrhoea or after eating. They can be heard even without a stethoscope. Bowel obstruction can cause hyperactive bowel sounds, as can food intolerance due to dietary changes.
In contrast, hypoactive or absent bowel sounds can indicate ileus. Ileus can occur in the setting of an abscess or a urinary tract injury, such as ureteral obstruction or urinary ascites from a cystotomy. It can also occur after abdominal surgery, causing intestinal motility to decrease. Bowel sounds may be absent or diminished in patients with peritonitis.

Peritonitis treatment includes antibiotics, surgery, and intravenous fluids
Peritonitis is a redness and swelling (inflammation) of the tissue that lines the abdomen, known as the peritoneum. This condition can quickly lead to serious health problems and can be deadly if not treated promptly. Treatment for peritonitis includes antibiotics, surgery, and intravenous fluids.
Antibiotics
Antibiotic therapy is a cornerstone of peritonitis treatment. It is recommended that empiric antimicrobial therapy be initiated within the first hour of recognising peritonitis in patients with compromised hemodynamic or organ function. For other patients, therapy should be initiated within 8 hours. Antibiotics should be continued for 4 to 7 days, and if symptoms have resolved by this time, they are no longer recommended. If the patient is recovering and can tolerate an oral diet, step-down therapy with oral antibiotics is appropriate.
Surgery
If a patient is very ill, surgery may be required to find and remove the source of the infection. Peritonitis can be caused by conditions such as appendicitis or an open sore in the stomach or intestine, and surgery is often necessary to treat these underlying causes.
Intravenous Fluids
Patients with peritonitis will be admitted to the hospital and given IV (intravenous) infection-fighting medicines to treat the infection. Intraperitoneal dosing is preferred over IV dosing for patients on peritoneal dialysis as it provides higher local levels of antibiotics. However, IV dosing is still a common and effective treatment for peritonitis.
Overall, the key to better outcomes for patients with peritonitis is appropriate identification and treatment, including antibiotics, surgery, and intravenous fluids.

Frequently asked questions
Peritonitis is the inflammation of the abdominal membranes, which is most commonly due to bacterial infection. It is a life-threatening condition that requires prompt medical treatment.
Symptoms of peritonitis include severe abdominal pain, swelling of the abdomen, fever, weight loss, and tenderness in one part or the entire abdomen. Patients with severe peritonitis often avoid all motion and keep their hips flexed to relieve abdominal wall tension.
Peritonitis can cause a decrease or absence of bowel sounds due to the development of ileus paralyticus (intestinal paralysis). However, in early mechanical bowel obstruction, hyperactive peristaltic waves can increase bowel sounds.
