Abstract

To evaluate the usefulness of the Sasada transbronchial angled forceps (STAF) in patients with peripheral pulmonary lesions (PPLs), which are difficult to manipulate with standard forceps. We have invented the STAF, a forceps with an angled tip. One hundred ten patients with PPLs that were difficult to reach with standard forceps were retrospectively evaluated. The patients first underwent bronchoscopy with a standard forceps and then with the STAF. The specimens obtained with standard forceps and those obtained with STAF were separately fixed and analyzed histologically. We compared the histologic diagnosis of the specimens obtained by STAF with that obtained by the specimens obtained with standard forceps. Statistical significance was calculated with the McNemar chi(2) statistic. The diagnostic yield of all lesions from the specimens obtained with STAF (86 of 110 lesions; 78.2%) was significantly higher than that of lesions from the specimens obtained with standard forceps (43 of 110 lesions; 39.1%; p < 0.001). Among malignant lesions, the yield obtained with STAF (60 of 72 lesions; 83.3%) was significantly higher than that obtained with standard forceps (32 of 72 lesions; 44.4%; p < 0.001). Among benign lesions, the yield ob...Continue Reading
