Acute appendicitis is a common and potentially serious medical condition characterized by inflammation of the appendix. The appendix is a small, finger-shaped pouch located in the lower right abdomen. When infected or blocked by stool, bacteria, or foreign bodies, it can become inflamed and lead to symptoms such as abdominal pain, fever, nausea, and vomiting. Prompt diagnosis and treatment of acute appendicitis are crucial to prevent complications such as perforation of the appendix, which can lead to peritonitis and other serious infections. Diagnosis is typically based on a combination of clinical symptoms, physical examination findings, and imaging tests such as ultrasound or CT scan. Treatment usually involves surgical removal of the inflamed appendix, known as an appendectomy. This can be done through traditional open surgery or minimally invasive laparoscopic surgery. With proper and timely intervention, most patients with acute appendicitis can recover fully without long-term complications.
