Percutaneous suction aspiration and drainage for pyogenic spondylitis.

STUDY DESIGN

Retrospective evaluation of results in 23 cases of early-stage pyogenic spondylitis treated with percutaneous suction aspiration and drainage.

OBJECTIVES

To evaluate the efficacy of percutaneous suction aspiration and drainage as a treatment method for early-stage pyogenic spondylitis.

SUMMARY OF BACKGROUND DATA

Traditional surgical treatment for pyogenic spondylitis has the disadvantage of increased morbidity caused by the extensive exposure required in the presence of infection. Recently, a few case reports have described minimally invasive treatment for pyogenic spondylitis in which percutaneous suction aspiration was used. However, the efficacy of this new treatment has not yet been evaluated.

METHODS

All charts, radiographs, and bacteriologic and histologic findings were reviewed. All 23 patients who received the new treatment were observed clinically and radiographically, to evaluate the efficacy of the treatment.

RESULTS

To date, all patients have been observed for more than 2 years. Twenty (87%) of the 23 patients have shown good results according to the evaluation. The causative organism was identified using tissue culturing in 12 (52%) of the 23 patients. The causative organism was Staphylococcus aureus in 8, and Staphylococcus epidermidis, Candida albicans, Pseudomonas aeruginosa, and Propionibacterium acnes in 1 each. Back pain as the major symptom in these patients was relieved within an average of 9.4 days after the operation. However, the patient in whom the spondylitis was caused by Candida albicans has received this new treatment twice without success.

CONCLUSIONS

Evaluation of percutaneous suction aspiration with drainage shows that it is an effective treatment for early-stage pyogenic spondylitis.
