Location of the appendix in the digestive system 3D model of appendicitis. Acute appendicitis seems to be the result of a primary obstruction of the appendix. [20] [10] Once this obstruction occurs, the appendix becomes filled with mucus and swells. This continued production of mucus leads to increased pressures within the lumen and the walls ...
The appendix, in a large majority of people, is located in the right lower quadrant. While this maneuver stretches the entire peritoneal lining, it only causes pain in any location where the peritoneum is irritating the muscle. In the case of appendicitis, the pain is felt in the right lower quadrant despite pressure being placed elsewhere.

A new analysis found that outpatient management of appendicitis with antibiotics is safe for selected patients, which may allow people to avoid hospitalization
In very rare cases, the appendix may not be present at all (laparotomies for suspected appendicitis have given a frequency of 1 in 100,000). [12] Sometimes there is a semi-circular fold of mucous membrane at the opening of the appendix. This valve of the vermiform appendix is also called Gerlach's valve. [4]
The appendix is commonly located in the retrocecal or pelvic region. The obturator sign indicates the presence of an inflamed pelvic appendix. Evidence shows that the obturator test does not adequately diagnose appendicitis, but can be used in conjunction with other signs and symptoms to make a diagnosis. [2]
