As a result of the experiment, the number of days it took to swallow LEGO after being swallowed into the feces was about 1.1 to 3 days, and it took 1. 71 days on average. Experiments also showed that females were more likely to be discharged as feces than men, but they could not be statistically verified from the number of subjects of six. In addition, there were no researchers who complained of abdominal pain etc. by LEGO.

Grace Leo, one of the coauthors of the paper and also the subjects, denied this, although it may be possible to show a different reaction in the intestines of the child, "The possibility of passing faster in the more mature intestines It is considered high. " Leo said, "In the case of a small foreign object like the head of a LEGO, the experiment results show that parents are worried and they do not resort to checking their children's flights, they are discharged out of the body properly. The result of this research will be to reassure parents who have small children. "

On the other hand, even if a child accidentally drinks 5 cm or more, a sharp point of 2.5 cm or more, a magnet, a coin, a button battery, and complains of pain, it is said that a doctor should be consulted promptly doing. The research team also warned that this experiment is a self experiment by a pediatrician and that it should not imitate similar experiments at home.
