Multiple @entity13391 with immediate Riu's stain via flexible fibreoptic bronchoscopy without fluoroscopic guidance in the diagnosis of XXXX .

@entity1 @entity13391 @entity358 @entity5
BACKGROUND: Accurate diagnosis of @entity358 usually relies on fluoroscopic guided procedures. As fluoroscopy is not routinely available in many respiratory units, an approach not using fluoroscopy but with a high diagnostic yield is highly desirable. METHODS: Immediate cytological examination of multiple @entity13391 using Riu's stain, a modified Wright's stain, was performed in 38 @entity1 with @entity358 not visible at bronchoscopy. The results were compared with the final diagnoses determined by histological examination or subsequent Papanicolaou staining of cytological specimens and clinical course. RESULTS: Of the 38 @entity1 29 were subsequently confirmed to have a @entity5 . Our method provided a diagnosis of @entity5 in 86% of these lesions. The accuracy (91%) and sensitivity (88%) were higher for lesions > 3 cm in diameter than for those of diameter < or = 3 cm (87% and 83%). There were no false positive results. The 29 lesions correctly diagnosed as malignant by Riu's stain required significantly fewer @entity13391 (mean (SD) 3 (2)) than the nine benign lesions (5 (4)). CONCLUSIONS: This technique provides a high diagnostic yield, avoids the need for fluoroscopy, and is probably safer than percutaneous biopsy.
