The lung of most reptiles has a single bronchus running down the centre, from which numerous branches reach out to individual pockets throughout the lungs.
If cancer growth blocks a short section of bronchus, brachytherapy (localized radiotherapy) may be given directly inside the airway to open the passage.
Generally, endoscopic stapling devices are used to ligate and divide the vessels and the bronchus however conventional suture material can also be used.
