Abstract
Background and objectives. Acute appendicitis is one of the most common surgical emergencies. Accurate diagnosis of acute appendicitis is based on careful history, physical examination, and laboratory investigation. The purpose of this study is to investigate the value of white blood cells (WBC) and C-reactive protein (CRP) in the diagnosis of acute appendicitis. Methods. A retrospective analysis of 350 files of patients who underwent appendectomy was conducted. Selected files were those patients who were admitted to ALmasara clinic Tripoli Libya between Aug 2011 to July 2023, ages of patients ranged from 18 to 80 years. Statistical analysis was performed using SPSS version 26 software. A statistical procedure was implemented to compare the hematologic parameters in two groups (Males and Females) to determine if there was any significant difference between them. Means of WBC, Neutrophil, Lymphocyte and CRP were compared between two groups by an independent one-way analysis of variance (ANOVA). Results. This study consisted of 350 participants who were diagnosed with appendicitis. The results showed that about (69.4%) of appendicitis patients exhibited a high white blood cell count (leukocytosis). Slightly over half (52.6%) of the participants had an elevated neutrophil percentage (neutrophilia). Approximately (64.3%) of the appendicitis patients had decreased lymphocyte percentage (lymphopenia). In relation to CRP values, the study showed that most participants (76.5%) had positive CRP results. Conclusion. Individuals with appendicitis have higher levels of leukocytes, neutrophils, and C-rea
