Surgical treatment of drug-resistant tuberculosis.

Abstract

The global emergence and spread of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis has led to the re-examination of surgery as a possible adjunctive treatment. We present the case of a 26-year-old HIV-seronegative patient with XDR pulmonary tuberculosis refractory to medical therapy. Surgical resection of the patient's solitary cavitary lesion was done as adjunctive treatment, and a successful outcome with a combination of surgery and drug therapy was achieved. We review the history of surgical therapy for tuberculosis and reports of its role in treatment of MDR and XDR tuberculosis. 26 case series and cohort studies were included, and together showed that surgical resection is beneficial in the treatment of drug-resistant tuberculosis. However, the results might not be applicable in all settings because investigations were observational and typically included patients with less severe disease, and all surgeries were done at specialised thoracic-surgery centres. Well designed studies are needed to establish the efficacy of surgery in treatment of drug-resistant tuberculosis.
