Abstract
Tracheoesophageal fistula (TEF) is a challenging condition that is difficult to treat. Several reports have described successful TEF treatment with an Amplatzer occluder (AGA Medical Corporation, Plymouth, Minnesota, USA) [1] [2]. However, Daniel et al. reported the case of a benign gastrobronchial fistula patient who underwent treatment with the Amplatzer device and died of fatal hemoptysis [3]. Inspired by this case, we developed a new dumbbell-shaped occluder device [4]. Compared with the Amplatzer occluder, this device has no protrusions, which reduces the risk of bleeding; even if the patient coughs, it will not increase airway damage.
