An Appraisal of Clinical and Hematological Parameters Linked to Recurrence in Surgically Drained Primary Psoas Abscesses: A Retrospective Comparative Study

Abstract

Aim: Psoas abscess is rare infectious condition with frequent complications in the diagnosis and treatment process. Unfortunately, there is limited information in the literature about the prognostic factors that determine the prognosis of psoas abscess. Therefore, the aim of this study was to evaluate the clinical and laboratory parameters associated with recurrence in primary psoas abscess. Material and Methods: Fifty-two patients who were diagnosed with psoas abscess and treated with surgical drainage in a university hospital between 1998 and 2018 were included in our study. The patients were seperated into two groups as those who recovered after surgical drainage (Group A) and those who developed recurrence (Group B). Clinical and laboratory data of the patients from the beginning of the preoperative period to the postoperative period were compared. Results: The mean age was 47.42±14.12 years in Group A and 53.81±15.83 years in Group B. The mean follow-up time was 43.96±14.29 months. The neutrophil to lymphocyte ratio was 11.38±1.69 in Group A and 18.75±2.31 in Group B (p=0.001). The platelet to lymphocyte ratio was 114.96±30.31 in Group A and 139.70±42.25 in Group B (p=0.016). The Acute Physiology and Chronic Health Evaluation (APACHE II) score was higher in Group B (p=0.001). Conclusion: According to the results of the current study, the neutrophil to lymphocyte ratio, the platelet to lymphocyte ratio, the APACHE II score, and the delayed diagnosis are all important prognostic indicators linked to recurrence in instances with primary psoas abscess.
