Regarding type of operation, 406 patients PARP inhibitor underwent opened appendectomy, 45 patients had laparoscopic appendectomy and 5 had laparoscopic converted to open with significant difference between them P < 0.0001. Table 1 Demographic characteristics of the patients Parameters All

Significant between variables was made using non parametric Chi-Square test. Table 2 showed the clinical and laboratory characteristics of patients subgroups according to the hisopathological findings. In normal, inflamed and complicated appendix, the type of pain was mainly localized 88,2%, 82.7%, 68.8% than generalized 13.8%, 18.3%, 31.2% with significant difference between groups P < 0.026. In normal, inflamed and complicated appendix, the duration of pain was mainly >12 hours, 75.9%, 88.3%, 98.7% than ≤12 hours, 24.1%,

11.8%, 1.3% with significant difference between patients subgroups P < 0.002. Fever was significantly higher in complicated than normal or inflamed appendix (64.9% versus 24.1% and 47.7%, P < 0.0001). WBCs and neutrophils counts were higher in inflamed (P < 0.019, P < 0.045) and complicated (P < 0.001, P < 0.001) than normal appendix and in complicated than inflamed appendix (P < 0.045, P < 0.004).
