Clinical Implications of Serum Bilirubin and Procalcitonin in the Diagnosis of Acute Appendicitis

Abstract

Acute appendicitis remains a common surgical emergency with challenges in prompt and accurate diagnosis. Serum biomarkers have garnered attention for their potential role in aiding diagnostic accuracy. This paper aims to update the clinical implications of serum bilirubin and procalcitonin levels in diagnosing acute appendicitis. A systematic review of literature was conducted, encompassing studies that investigated the relationship between serum bilirubin and procalcitonin levels and acute appendicitis. The search strategy included electronic databases, resulting in a comprehensive analysis of relevant articles. The findings suggest a notable association between elevated serum bilirubin levels and the presence of acute appendicitis. Furthermore, procalcitonin exhibited promising diagnostic potential, demonstrating a significant correlation with the severity of appendicitis. Subgroup analyses revealed varied sensitivity and specificity values, indicating the need for further refinement in clinical application. The integration of serum biomarkers, specifically bilirubin and procalcitonin, into the diagnostic algorithms of acute appendicitis could potentially enhance the accuracy of clinical assessments. However, limitations in existing studies, such as heterogeneity in patient populations and differing assay methodologies, emphasize the necessity for standardized protocols and larger prospective trials. In conclusion, serum bilirubin and procalcitonin levels show promise as adjunctive tools in diagnosing acute appendicitis. Their incorporation into clinical practice warrants careful consideration and validation through larger-scale studies to delineate their precise diagnostic utility, thereby potentially optimizing patient care pathways in the context of this prevalent surgical condition.
