Pak J Med Health Sci Jan ;13(4):817-9.

Aim : To assess the outcome of ultrasound guided needle aspiration in treatment of Psoas abscess. Methodology: This study was conducted in the department of Surgery Unit -II Ghulam Muhammad Mahar Medical College Teaching Hospital Sukkur from January 2015 to January 2019. Patients diagnosed of having Psoas abscess more than 5cm were included in the study. Aspiration was performed with 16/18 gauge spinal needle under local anesthesia under ultrasound guidance. Patients were called back after one week and reassessed for recurrent abscess. Repeat needle aspiration performed under ultrasound guidance where ever required. Results: Mean age of subjects was 39.25 ±9.8. Males were 69.3% and females 30.7%. The size of the abscess range between 5cm to 23cm with average size of 14.9cm. Predominantly right side was affected 31( 77.5%). Needle aspiration was successful in 28(70%) patients on 1st attempt, while 12(30%) patients required 2nd attempt after one week. On follow up after two weeks incomplete resolution / recurrence was found in 3(7.5%) patients who were subjected to incision and drainage. Mycobacterium T.B was found most frequent pathogen (65%) and staphylococcus aureus (22.5%), E-coli (7.5%) and pseudomonas (5%). Conclusion: It is concluded that percutaneous needle aspiration is a better option to treat psoas abscess. It is less painful, cost effective & does not need hospitalization. No wound care is required in comparison to open incision drainage.
