Data on ultrathin bronchoscopy (UB) for this purpose is limited. To evaluate feasibility and safety of UB compared to SB for diagnosis of SPL in a TB endemic region. Methods: In this prospective randomised trial we compared diagnostic yield and adverse events of UB with standard- size bronchoscopy (SB), both combined with fluoroscopy, in a cohort of patients with SPL located beyond the visible range of SB. Results: We included 40 patients (mean age 55.2 years, 45 % male) with malignant SPL ( n = 16; 40 %), tuberculous SPL ( n = 11; 27.5 %) and other benign SPL ( n = 13; 32.5 %). Mean procedure time in UB and SB was 30.6 and 26.0 min, respectively ( p = 0.15). By trend, adverse events were recorded more often with UB than with SB (30.0 vs. 5.0 %, p = 0.091), including extensive coughing ( n = 2), blocked working channel ( n = 2), and arterial hypertension requiring therapeutic intervention ( n = 1), all with UB. The overall diagnostic yield of UB compared to SB was 55.0 % vs. 80.0 %, respectively ( p = 0.18). Sensitivity for the diagnosis of malignancy of UB and SB was 50.0 % and 62.5 %, respectively ( p =0.95). Conclusion: UB is not superior to SB for the evaluation of SPL in a region endemic with tuberculosis, when combined with fluoroscopic guidance only.
