The Role of Ballooning in Patients with Post-tuberculosis Bronchial Stenosis / 결핵및호흡기질환

ABSTRACT

BACKGROUND: In order to access the role of ballooning in patients with post-tuberculosis bronchial stenosis (PTBS), medical records of patients who underwent the procedure were reviewed. METHODS: Twenty-nine PTBS patients underwent balloon dilatation between May 1999 and November 2000 at Samsung Medical Center. The median age was 28 (range 16~62 year) and most patients were female (n=27, 93%). The mean number of ballooning procedures was 2.4 (range 1~8) and the interval between ballooning procedures was 76.2+/-69.7 days. RESULTS: In general, the FEV1 was improved after ballooning (from 66.2.+/-11.9% predicted to 73.5+/-13.0% predicted, p=0.0004). Among 29 patients who underwent ballooning, a clinically successful outcome was observed in 16 patients (55%). Comparison between the successful and unsuccessful groups showed that favorable factors for a successful outcome were a higher pre-ballooning FEV1 (71.1+/-8.1 vs. 60.2+/-13.3% predicted), higher post-ballooning FEV1 (89.2+/-7.8 vs. 63.4+/-9.2% predicted) and absence of left upper lobe collapse. The clinical outcome was unsuccessful in all eight patients with a pre-ballooning FEV1 57% of predicted and there is no complete left upper lobe lung collapse.
