Ilio-psoas abscesses: percutaneous drainage under image guidance.

Abstract

Over a 5-year period, 56 psoas abscesses occurring in 51 patients were managed by image-guided percutaneous drainage, either by needle aspiration (n = 10) or by catheter drainage (n = 46) in conjunction with medical therapy. Twenty-seven patients had tuberculous abscesses (bilateral in five) while 24 patients had pyogenic abscesses. Percutaneous treatment was successful in 16 of the 24 patients (66.7%) with pyogenic abscesses. The reasons for failure were co-existent bowel lesions, phlegmonous involvement of muscle without liquefaction, multiloculated abscess cavity and thick tenacious pus not amenable to percutaneous drainage. Surgery was required in seven patients, either for failed percutaneous drainage or for the management of co-existent disease. Percutaneous drainage was initially successful in all 27 patients of tuberculous psoas abscesses. However, eight patients presented with recurrence requiring repeat intervention. The average duration of catheter drainage was longer in patients with tuberculous abscess (11 days) than in patients with pyogenic abscess (6 days). Percutaneous drainage under image guidance provides an effective and safe alternative to more invasive surgical drainage in most patients with psoas abscesses.
