An acutely inflamed and enlarged schwartz textbook of surgery pdf, sliced lengthwise. Appendicitis is inflammation of the appendix.
Symptoms commonly include right lower abdominal pain, nausea, vomiting, and decreased appetite. Severe complications of a ruptured appendix include widespread, painful inflammation of the inner lining of the abdominal wall and sepsis. Appendicitis is caused by a blockage of the hollow portion of the appendix. 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 appendix, decreased blood flow to the tissues of the appendix, and bacterial growth inside the appendix causing inflammation.
