Abstract

Background

Foreign body airway obstruction is a significant public health issue around the world. Mochi, a traditional sticky rice cake in Japan, has gained popularity in many countries including the USA. However, the associated aspiration danger has not yet been well recognized.

Case presentation

We describe three cases of foreign body airway obstruction due to mochi. Case 1 was an elderly man who was brought to the emergency department by an ambulance after he choked on mochi. Despite extensive efforts to remove pieces of mochi including use of Magill forceps, bronchoscopy, and endotracheal intubation, he suffered severe hypoxia and died. Case 2 was a middle-aged man who was found unconscious in a park. The rhythm upon arrival was pulseless electrical activity. During intubation, large pieces of mochi were found in the oropharynx and removed with Magill forceps. He developed aspiration pneumonitis and hypoxic brain injury. The patient was discharged to a skilled nursing facility with severe neurological disability. Case 3 was an elderly man who choked while eating soup with mochi at home. His initial cardiac rhythm was asystole. During intubation, obvious foreign body was found in the oropharynx. Several pieces of mochi were removed by suctioning through the endotracheal tube. He suffered severe hypoxic injury and died.

Conclusions

All of our cases resulted in death or poor neurological outcome. As the popularity of mochi continues to increase, it is likely that cases of aspiration from mochi will also increase. Emergency physician should be aware of the potential danger of mochi and be familiar with the techniques to remove mochi from the airway.
