- W2159291236 abstract "The development of necrosis of the appendix increases the risk of perforation with peritonitis. Mechanical obstruction of the lumen, inflammation-induced ischemia, thrombosis, and bacterial overgrowth together contribute to the development of gangrene. In addition, genetic factors may play a protecting role in response to local infection, thus preventing progression of inflammation into gangrene (1). Necrosis does not develop during the earliest phase of the inflammation. If necrosis of the appendix develops, it does not immediately proceed to perforation as many non-perforated appendices have gangrene in pathological examination. On the contrary, perforation occurs always at the site of gangrenous wall of the appendix. A number of earlier studies have demonstrated that longer duration of symptoms before surgery is associated with perforation of the appendix (1–3). Early diagnosis and surgical removal of the appendix has therefore been a gold standard in patients with appendicitis in order to prevent perforation and peritonitis. Hornby and colleagues report results of a registry-based study of over 2400 patients operated on for suspected appendicitis. The main finding in the study was that the proportion of patients having their normal appendix removed increased as the time interval to surgery increased but the proportion of necrotic appendicitis did not change. These results most likely reflect problems in diagnostic workup in patients with suspected appendicitis. The decision to operate was most probably done earlier in those patients with typical signs and symptoms whereas in other patients more follow-up or other diagnostic workup may have been needed before the decision to operate was done. The high proportion of normal appendices found at surgery probably indicates that computed tomography (CT)-scan was not used in patients with suspected appendicitis during the" @default.
