In a way that uses or relates to a bronchoscope; by means of examining the lungs with a bronchoscope.
From bronchoscopic + the adverb suffix '-ly'. This suffix transforms adjectives into adverbs showing how something is done.
Adding '-ly' to adjectives is English's favorite way to turn descriptions into 'how' words—bronchoscopically sounds fancy, but it just means 'using a bronchoscope to look at lungs.'
