<unk>  is inflammation of the<unk> pendix. Symptoms commonly include right lower abdominal pain, nausea, vomiting, and decreased<unk> petite. However,<unk> proximately 40% of people do not have these typical symptoms. Severe complications of a ruptured<unk> pendix include widespread, painful inflammation of the inner lining of the abdominal wall and sepsis.<unk>  is caused by a blockage of the hollow portion of the<unk> pendix. This is most commonly due to a calcified "stone" made of feces. Inflamed lymphoid tissue from a viral infection, parasites, gallstone, or tumors may also cause the blockage. This blockage leads to increased pressures in the<unk> pendix, decreased blood flow to the tissues of the<unk> pendix, and bacterial growth inside the<unk> pendix causing inflammation. The combination of inflammation, reduced blood flow to the<unk> pendix and distention of the<unk> pendix causes tissue injury and tissue death. If this process is left untreated, the<unk> pendix may burst, releasing bacteria into the abdominal cavity, leading to increased complications. The diagnosis of<unk>  is largely based on the person's signs and symptoms. In cases where the diagnosis is unclear, close observation, medical imaging, and laboratory tests can be helpful. The two most common imaging tests used are an ultrasound and computed tomography (CT scan). CT scan has been shown to be more accurate than ultrasound in detecting acute<unk> . However, ultrasound may be preferred as the first imaging test in children and pregnant women because of the risks associated with radiation exposure from CT scans. The standard treatment for acute<unk>  is surgical removal of the<unk> pendix. This may be done by an open incision in the abdomen (laparotomy) or through a few smaller incisions with the help of cameras (laparoscopy). Surgery decreases the risk of side effects or death associated with rupture of the<unk> pendix. Antibiotics may be equally effective in certain cases of non-ruptured<unk> . It is one of the most common and significant causes of abdominal pain that comes on quickly. In 2015 about 11.6 million cases of<unk>  occurred which resulted in about 50,100 deaths. In the United States,<unk>  is one of the most common cause of sudden abdominal pain requiring surgery. Each year in the United States, more than 300,000 people with<unk>  have their<unk> pendix surgically removed. Reginald Fitz is credited with being the first person to describe the condition in 1886. script)
