K81.0 Acute cholecystitis

Name of the Condition

Summary

Acute cholecystitis is the sudden inflammation of the gallbladder, often resulting from a blockage, usually by gallstones. It leads to pain in the upper right abdomen and requires prompt medical attention.

Causes

The most common cause of acute cholecystitis is gallstones blocking the cystic duct, leading to inflammation. Other causes include tumors, severe illness, or infections causing bile flow obstruction.

• HIDA scan for evaluating gallbladder function

Treatment Options

• Dietary modifications, such as avoiding fatty foods
• Surgical options, generally laparoscopic cholecystectomy, to remove the gallbladder if necessary

Prognosis and Follow-Up

With appropriate treatment, most individuals recover completely, especially those who undergo gallbladder removal. Regular follow-up is essential to ensure complete recovery and to monitor for any signs of complications.

Complications

• Gallbladder rupture
• Bacterial infection of the bile duct system
• Necrosis of the gallbladder tissue
