K35.891

Clinical Causes: Blockage of the appendix opening by fecaliths, foreign bodies, or lymphoid tissue swelling Infections caused by bacteria or viruses leading to inflammation Reduced blood flow to the appendix, possibly due to blood clots or other circulatory issues Underlying health conditions that impair immune response

Key Symptoms: Sudden onset of sharp pain in the lower right abdomen, which may worsen over time Pain that initially may be generalized around the abdomen and then localizes to the right lower quadrant Nausea and vomiting Loss of appetite Low-grade fever or chills Swelling or tenderness upon abdominal examination Possible signs of systemic infection such as feeling unwell or fatigue

Diagnosis Path: Physical examination to check for abdominal tenderness and signs of inflammation Imaging studies such as ultrasound or computed tomography (CT) scan to visualize the appendix and assess for gangrene or other complications Blood tests to detect elevated white blood cell counts indicative of infection Possible urine tests to rule out other causes of abdominal pain

Treatment Protocols: Appendectomy: Surgical removal of the inflamed appendix, often performed laparoscopically or via open surgery Antibiotic therapy to combat infection and reduce inflammation Pain control with appropriate medications Monitoring for signs of perforation or abscess formation Postoperative care including rest, wound care, and follow-up assessments
