ICD-10: K65.0

Generalized acute peritonitis, classified under ICD-10 code K65.0, is a serious medical condition characterized by the inflammation of the peritoneum, the membrane lining the abdominal cavity. This condition can arise from various underlying causes and requires prompt medical attention due to its potential complications.

Clinical Description

Definition

Generalized acute peritonitis is defined as a widespread inflammation of the peritoneum, often resulting from infection or irritation due to the presence of bacteria, chemicals, or other irritants in the abdominal cavity. It is considered a surgical emergency and can lead to severe complications if not treated promptly.

Etiology

The causes of generalized acute peritonitis can be categorized into several groups:

• Infectious Causes: The most common cause is the perforation of abdominal organs, such as the appendix (appendicitis), stomach (peptic ulcer), or intestines (diverticulitis). Other infectious sources include pelvic inflammatory disease and spontaneous bacterial peritonitis in patients with liver cirrhosis.

• Non-Infectious Causes: Chemical irritation from substances like bile or pancreatic enzymes can also lead to peritonitis. Trauma to the abdomen, such as from a gunshot or stab wound, can introduce bacteria and cause inflammation.

Symptoms

Patients with generalized acute peritonitis typically present with:

• Abdominal Pain: Severe, diffuse abdominal pain that may worsen with movement.
• Tenderness: The abdomen is often tender to touch, and patients may exhibit guarding or rigidity.
• Fever: A high fever is common, indicating an inflammatory response.
• Nausea and Vomiting: These symptoms may accompany the abdominal pain.
• Changes in Bowel Habits: Patients may experience constipation or diarrhea.

Diagnosis

Diagnosis of generalized acute peritonitis involves a combination of clinical evaluation and diagnostic imaging:

• Physical Examination: A thorough examination reveals abdominal tenderness, rigidity, and signs of peritoneal irritation.
• Imaging Studies: Abdominal ultrasound or CT scans are often utilized to identify the source of infection or perforation.
• Laboratory Tests: Blood tests may show elevated white blood cell counts and signs of infection.

Treatment

The management of generalized acute peritonitis typically requires surgical intervention:

• Surgery: The primary treatment is often an exploratory laparotomy to identify and address the underlying cause, such as repairing a perforated organ or draining abscesses.
• Antibiotics: Broad-spectrum intravenous antibiotics are administered to combat infection.
