%X The clinical data of 196 patients who have undergone conventional appendectomy between March 2007 and April 2008 were collected retrospectively. Patients were examined for age, sex, white blood cell count, ultrasonography results, histopathological diagnosis and hospital stay.Negative appendectomy rate was 17.3% (27% for female, 11.5% for male). White blood cell counts were found to be high in 83% for acute appendicitis group and %61 for negative appendectomy group. There were 66 (34%) patients who had negative USG findings for acute appendicitis. Of these patients, histopathological examination revealed acute appendicitis in 46 patients whereas 20 patients had normal appendix. Hospital stays were 2.79 +/- 1.9 and 2.66 +/- 1.7 days for negative and positive appendicectomies respectively.Besides the improvement of diagnostic tests for acute appendicitis, we could not sufficiently reduce the negative appendectomy rate.Appendicectomy is still the most common procedure in general surgery practice but diagnostic failure may still occur and this leads to delay in treatment or negative (non-therapeutic) appendectomies. We aimed to analyze retrospectively the diagnostic efficiency of the preoperative tests in relation with histopathologic results.Data of the 277 conventional appendectomies performed for acute appendicitis (AA) between March 2007 and April 2008 were collected. Fifteen patients with perforated appendicitis, 23 patients whose preoperative laboratory tests performed at another centre and 43 patients operated on without preoperative ultrasonography (USG) were excluded. In the remaining 196 patients, all had clinical findings such as, history of anorexia, pain followed by nausea, right lower quadrant pain, vomiting, rebound tenderness, guarding, rigidity and conventional appendectomies were carried out. A radiologist performed a graded compression USG (Siemens Sonoline G50) with a 3.5 MHz convex and 7.5 MHz linear probe. Data for age, sex, white blood cell count,
