PSOAS ABSCESS – THE CHANGING TRENDS
Introduction: Psoas abscess (IPA) is an abscess collection in the retroperitoneal space tracking along the psoas major muscle. The microbial etiology of Psoas abscess is variable and depends on the geographical area. This study attempts to evaluate the microbial etiology, its implication in deciding the management modalities, and outcomes in patients with Psoas abscess from a tertiary care center in South India.
Materials and Methods: This was a retrospective study done in a tertiary care center in Southern India. Results: A total of 47 patients were enrolled in the study, with causative organism identified in 40 (85.15%) patients. In 17 patients (36.17%), it was found to be tuberculous origin; and of nontuberculous origin in 23 patients (48.93%). No causative organism could not be isolated in 7 patients (14.89%). While 33 patients were treated with percutaneous drainage (70.12%), open drainage was done in 14 patients (29.78%) and 1 patient died (2.12%).
Conclusion: The most common causative organism of psoas abscess is found to be of nontuberculous origin and PCD was found to be better modality of treatment. Empirical administration of anti-tuberculous drugs needs further evaluation.
