Direct   examination    of   the   tracheobronchial   tree  with   flexible

   fiberoptic  bronchoscopy has  greatly  facilitated  the  diagnosis , staging

   and management   of   pulmonary   neoplasms  and other lung diseases.

   The purpose of this brief review is assessed to see the indication and rate

   of diagnosis of this procedure in a regional center such as Hamadan.

         Fiberoptic bronchoscopy survey in 300 patients in a two year study by

   author showed that its most important indication in 261 cases  (87%)  was

   for  the  diagnosis  of  bronchogenic  carcinoma  and  210 cases of them

   (85%) showed abnormal changes in the bronchi.Malignancy was proved

   in 183  cases  by  pathologic  investigations.   The  commonest  radiologic

   finding which could reveal of abnormal bronchoscopy view was collapse

   atelectasis and central opacity followed by RUL involvment.

         Recently with using brushing biopsy  and  providing  cell block ,  some   

   experiments are being brought into existance in Hamadan.Complication

   with  this  procedure  are  very rare  and concerning the efficiency of this

   procedure    in    out    patients    with   local   anasthesia   and  the   least

   preparation  has plain preference to rigid bronchoscope.
