Appendicitis and mimicking conditions. A prospective study.
A prospective study of 444 consecutive patients diagnosed as having acute appendicitis was carried out in a district general hospital. The appendix was acutely inflamed, gangrenous, or perforated in 346 patients. Diagnostic error, 22% overall, was twice as common in females as in males. Organisms were isolated from the outer appendix wall in 117 patients, isolation increasing with the severity of inflammation. 12% of children under 11 had mesentric adenitis, 10% of all females had gynaecological lesions, and 14% of patients over 50 had acute diverticulitis. In only 6% of patients was no abnormality found at operation, and in every case the disorder was dealt with through the gridiron incision.
