Abstract:
A 63-year-old man who had received a permanent tracheostoma after oesophageal cancer surgery developed fistulas in the left and right main bronchi and suffered repeated aspiration pneumonia. Placing an indwelling Dumon Y-stent using a rigid bronchoscope is an option to treat fistula and stenosis at the tracheal bifurcation, but in some cases, it may be difficult to use a rigid bronchoscope in patients with a permanent tracheostoma. In this study, we report placing a Dumon Y-stent in a patient with a permanent tracheostoma using a specially modified stent and forceps instead of a rigid bronchoscope.

Consider two children sitting on a seesaw, which has negligible mass. The first child has a mass (m1) of 26 kg and sits at point A, which is 1.6 meters (r1) from the pivot point B; the second child has a mass (m2) of 32 kg and sits at point C. How far from the pivot point B should the second child sit (r2) to balance the seesaw?
