K82.2 Perforation of gallbladder

Name of the Condition

• Perforation of Gallbladder

Summary

Perforation of the gallbladder is a serious complication where the gallbladder wall ruptures, often due to inflammation, infection, or trauma. This can lead to bile leakage into the abdominal cavity, causing peritonitis or abscess formation. The condition requires prompt medical attention to prevent life-threatening complications.

Causes

Perforation typically occurs secondary to acute cholecystitis (gallbladder inflammation), often caused by gallstones obstructing the cystic duct. Severe infection, gangrene, or trauma to the gallbladder can also lead to rupture. In rare cases, perforation may result from malignancy or iatrogenic injury during procedures.

Risk Factors

• Gallstone disease (cholelithiasis)
• Acute or chronic cholecystitis
• Advanced age
• Diabetes mellitus
• Immunosuppression
• Delayed treatment of gallbladder inflammation
• Prior history of gallbladder surgery or procedures

Symptoms

• Sudden, severe right upper abdominal pain
• Fever and chills
• Nausea or vomiting
• Abdominal rigidity or tenderness
• Signs of peritonitis (e.g., rebound tenderness)
• Hypotension or shock in severe cases

Diagnosis

Imaging studies such as ultrasound or CT scans to detect gallbladder rupture, fluid collections, or free air in the abdomen. Blood tests to assess for infection, leukocytosis, or elevated liver enzymes. Clinical evaluation of symptoms and physical examination to identify peritoneal signs.

Treatment Options

• Emergency surgical intervention (cholecystectomy or drainage) to repair the perforation and manage infection.
• Intravenous antibiotics to treat peritonitis or sepsis.
• Supportive care, including fluid resuscitation and pain management.
• In some cases, percutaneous drainage of abscesses may be performed.

Prognosis and Follow-Up

Prognosis depends on the timeliness of treatment and the presence of complications. Early intervention improves outcomes, but perforation carries a higher risk of mortality compared to uncomplicated gallbladder disease. Follow-up includes monitoring for infection resolution and assessing for long-term gallbladder function or the need for further surgery.

Complications

• Peritonitis (infection of the abdominal lining)
• Abscess formation
• Sepsis or septic shock
• Biliary fistula (abnormal connection between bile ducts)
• Adhesions or bowel obstruction
• Recurrent gallbladder disease

Lifestyle & Prevention

• Maintain a healthy weight to reduce gallstone risk.
• Avoid rapid weight loss, which can increase gallstone formation.
• Eat a balanced diet low in saturated fats and high in fiber.
• Manage underlying conditions like diabetes or liver disease.
• Seek prompt treatment for gallbladder inflammation to prevent progression.

When to Seek Professional Help

Seek immediate medical attention if you experience sudden, severe abdominal pain, fever, or signs of shock. Perforation is a medical emergency requiring urgent evaluation and intervention.

Tips for Medical Coders

Document the perforation and its underlying cause (e.g., cholecystitis, gallstones) clearly. Include details about the clinical presentation, imaging findings, and surgical or medical management. Ensure the code K82.2 is supported by documentation of gallbladder rupture and associated complications.
