Appraisal of Various Predictors for Complicated Appendicitis in Adults; A Comparative Study Between Complicated and Non-Complicated Appendicitis

Abstract

Background: Acute appendicitis is the most common non traumatic surgical abdominal emergency, and is the first operation done by most of the general surgeon during their training period. The most important aspect in the management of acute appendicitis, is early diagnosis and intervention to avoid the development of complications.Patients and methods: This prospective study included 184 patients diagnosed with acute appendicitis who were grouped into complicated and non- complicated appendicitis. Both groups were compared to detect predictors for complicated appendicitis to prevent delay management. Results: About 82.6% of our patients were below 30 years (mean: 23.8 years) and 59.2% were females. Histopathology confirmed acute appendicitis in 86.5 %, chronic appendicitis in 12.5%, and normal appendix in 1.1%. About 81.5% have ALVARADO score equal or greater than 7. Complicated appendicitis was diagnosed in 23.37% of patients. There was a significant correlation between complicated appendicitis and gender, rebound tenderness, elevated temperature, elevated WBC, shift to left of WBC and Modified Alvarado Scoring (P values 0.000,0.002,0.001,0.000,0.000, and 0.006), other parameters showed no significant correlations. Conclusion: The rate of complicated appendicitis should be reduced to decrease the associated morbidity, the presence of rebound tenderness, fever, high WBC count and sift to left, a score of 7 or more by modified ALVAADO score, and male sex are highly suggestive. The presence of these factors mandates early and prompt intervention.
