Peritonitis is an inflammation of the peritoneum (abdominal lining), usually caused by a perforation in the digestive system or a ruptured appendix. Peritonitis can also occur due to an infection caused by bacteria or fungi, or irritation from bodily fluids. This condition can affect the organs within the abdomen, leading to serious health problems and even sepsis. The most common symptom is severe abdominal pain.

Peritonitis is inflammation of the peritoneum, the lining of the abdomen surrounding the organs, caused by bacteria, fungi, or body fluids. Infected body fluids or any infection can trigger peritonitis. Peritonitis is divided into two main types:

• Spontaneous bacterial peritonitis: This type of peritonitis is an inflammation caused by bacteria that usually occurs as a result of conditions such as kidney disease or cirrhosis.
• Secondary peritonitis: This type of peritonitis develops due to a hole or tear in an organ in the abdomen.

Peritonitis can lead to serious health problems if left untreated. Treatment usually involves surgery, and depending on the cause of the infection, antibiotics may also be used. Peritonitis is a condition that requires immediate medical attention.

Peritonitis symptoms: What are the indicators of intra-abdominal infection?

 Peritonitis (intra-abdominal infection) symptoms may occur as follows:

• Severe abdominal pain and tenderness: The most obvious symptom is usually severe abdominal pain. This pain can be felt through tenderness to touch in the abdominal area.
• Swollen abdomen: Peritonitis can cause a feeling of swelling and tightness in the abdomen due to inflammation inside the abdomen.
• Dehydration: Loss of body fluids may occur due to symptoms such as nausea and vomiting, which can lead to dehydration.
• Fever: Fever may occur with an increase in body temperature.
• Nausea and vomiting: Inflammation in the abdomen can affect movement in the stomach and intestines, causing nausea and vomiting.
• Rapid pulse: When the body is inflamed, the heart may beat faster and the pulse may accelerate.
• Shortness of breath: Peritonitis can restrict the movement of the diaphragm due to inflammation inside the abdomen, leading to difficulty breathing.
• Fatigue and weakness: Inflammation and infection can be energy-intensive for the body, leading to fatigue and weakness.
• Edema in the legs and feet: Edema (swelling) may occur in the legs and feet as a result of intra-abdominal fluid accumulation.
• Easy bruising and bleeding (Thrombocytopenia): Peritonitis can affect blood clotting and cause a decrease in the platelet count.

Peritonitis is a serious condition and requires immediate medical attention. If you experience these symptoms, it's important to seek emergency medical attention.

What are the causes of peritonitis (intra-abdominal infection)?

Peritonitis (Intra-Abdominal Infection) can usually occur due to the following reasons:

Infections:

• Bacteria and fungi: A puncture or tear in the abdominal organs can allow bacteria and fungi to enter the abdominal cavity. This can lead to infection, triggering peritonitis.
• Gallbladder problems: Bile leaking from the gallbladder can cause inflammation and infection in the abdomen. This condition is called cholecystitis.
• Pancreatitis: When the pancreas becomes inflamed, this can cause an infection in the abdomen.
• Ulcers: Ulcers in the lining of the stomach can cause stomach acid to leak into the tissues within the abdomen.

 Chemical causes:

• A tumor or cyst that ruptures in your abdomen: This can lead to chemical peritonitis.
• Ulcerative Conditions of the Stomach: Ulcerative conditions can trigger peritonitis through chemical reactions.

Cirrhosis: Severe damage to the liver can cause fluid to leak into the abdominal cavity, leading to peritonitis.

Other reasons:

• Appendicitis : If the appendix bursts or ruptures, this can cause peritonitis.
• Peptic ulcer: Perforation of the stomach ulcer may cause leakage of stomach contents into the abdominal cavity.
• Diverticulitis: Peritonitis may occur if the inflamed sacs formed in the intestinal wall burst.
• Infectious pancreatitis: When the pancreas becomes inflamed, this can bring infection with it, causing peritonitis.
• Ectopic pregnancy: If the pregnancy develops outside the uterus (ectopic pregnancy), this can lead to peritonitis.
• Trauma or injury to the abdomen: Trauma or injury to the abdominal area can trigger peritonitis.
• Abdominal surgery: Complications that develop after some surgical interventions may cause peritonitis.

Peritonitis is often a serious condition and can be life-threatening if left untreated. Therefore, it is important to seek medical attention immediately if you notice symptoms of peritonitis.

How is peritonitis diagnosed?

The following steps can be followed to diagnose peritonitis:

Patient history and physical examination: The specialist will perform a medical history and physical examination to assess the patient's symptoms and confirm the suspicion of peritonitis. Symptoms such as abdominal pain, swelling, and tenderness will be reviewed.

Laboratory tests:

• Blood tests: Blood tests provide information about signs of infection, indicators of inflammation, and organ function.
• Fluid analysis: Analysis of fluid in the abdominal cavity can help determine the cause of the infection.
• Urine tests: Urine tests can provide information about kidney function and other changes in the body.

Imaging tests:

• X-ray: Can be used to view the abdominal area. X-rays can show signs such as free air or fluid accumulation.
• Computed tomography (CT): An imaging test that provides more detailed images. It can reveal conditions such as inflammation or free fluid accumulation within the abdomen.
• Magnetic resonance imaging (MRI): Allows for more detailed imaging of soft tissues.

Laparoscopy or laparotomy:

• Laparoscopy: This procedure uses a small camera and a thin tube to examine the organs inside the abdomen.
• Laparotomy: A large incision is made inside the abdomen, allowing for detailed examination. This procedure is generally reserved for more serious cases.

Biopsy: If necessary, a biopsy may be performed to take a sample of tissue from inside the abdomen.

Diagnosis of peritonitis is based on a combination of symptoms, physical examination, and various tests. Depending on the severity of the patient's condition, it is important to begin treatment promptly.

How is peritonitis (intra-abdominal infection) treated?

Treatment for peritonitis generally includes the following methods:

• Antibiotic treatment: If the infection is caused by bacteria, broad-spectrum antibiotics may be prescribed. Antibiotics are used to control the infection and prevent it from spreading. Regular and full-dose antibiotics are essential throughout the treatment process.
• Surgical intervention: If peritonitis is caused by conditions such as appendicitis, peptic ulcers, or diverticulitis, surgical intervention may be necessary. Surgery removes the source of infection and closes the perforation or tear.
• Fluid and electrolyte therapy: In severe cases of peritonitis, fluid accumulation may occur due to inflammation in the abdominal cavity. Intravenous (IV) fluid therapy may be administered to maintain fluid and electrolyte balance.
• Pain Management: Severe abdominal pain is often a prominent symptom of peritonitis. Pain relievers or anti-inflammatory medications can be used to control the pain.
• Supportive therapy: Supportive therapy may be administered to stabilize the patient's general condition in the treatment of peritonitis. This may include supporting the patient's respiratory, circulatory, and other organ functions.

Treatment may vary depending on the cause of peritonitis, the patient's overall health, and the severity of the infection. Initiating treatment early can reduce the risk of complications and improve the patient's chances of recovery. The treatment plan is determined by the specialist and tailored to the patient's individual situation.

What happens if peritonitis is not treated? 

Peritonitis is inflammation of the peritoneal lining and is usually caused by an infection. This condition is a serious medical emergency and can be life-threatening if left untreated. If peritonitis is left untreated, the following complications can occur:

• Shock: Peritonitis can cause an overreaction of the body's defense mechanisms. This can lead to a drop in blood pressure and failure of body organs to receive adequate oxygen and nutrients, which can lead to shock.
• Sepsis: Peritonitis can cause a widespread infection throughout the body, which can lead to sepsis. Sepsis is a life-threatening condition that can damage organs throughout the body.
• Organ failure: Peritonitis can cause failure of vital organs, particularly the liver, kidneys, and heart. Organ failure can lead to the malfunctioning of body systems and the disruption of vital functions.
• Abscesses: Peritonitis can lead to the formation of abscesses in the abdominal cavity. These abscesses can cause complications by causing an accumulation of inflammatory fluid and tissue.
• Chronic peritonitis: If left untreated, peritonitis can become chronic, causing persistent inflammation that can lead to long-term health problems.

For these reasons, peritonitis is a serious condition and should be evaluated and treated immediately by a healthcare professional. Peritonitis usually requires surgery, antibiotic therapy, and supportive care. If left untreated, the consequences can be serious and life-threatening.
