| Abstract |
PURPOSE
Multiple methods are used to diagnose acute appendicitis. However, with the current practice, the negative laparotomy rate for acute appendicitis is from 15% up to 30%. This study was designed to evaluate various pathologies of the appendix and other intraabdominal organs of patients preoperatively diagnosed with acute appendicitis and to analyze clinically the difference between acute appendicitis and other intraabdominal inflammatory diseases.
METHODS
We reviewed the pathologic reports of 833 patients who underwent laparotomies for acute appendicitis from January 1997 to December 2001. We grouped these patients by pathology. Group I included patients with a negative appendectomy and no other intraabdominal pathology, group II included those with lesions within the appendix, and group III, those with intraabdominal lesions other than in the appendix. We also analyzed the age, sex distributions, the typical symptoms of appendicitis, the duration of symptoms, fever, and leukocytosis of 100 patients with typical appendicitis by random sampling to find the clinical differences that existed between pelvic inflammatory disease and cecal diverticular disease presented as appendicitis.
RESULTS
The diagnostic accuracy for acute appendicitis was 79.7%, and the negative appendectomy and negative laparotomy rates were 17.4% and 15.5%, respectively. The percents of patients in group I, II, and III were 10.4%, 82.6%, and 7.0%, respectively.
CONCLUSIONS
It is important to consider the possibility of various pathologies during diagnostic and operative procedures for an acute abdomen, especially one occurring in the right lower quadrant. |
