Does the endoscope break the fast?

Question : What do you say if a doctor inserts the examining instrument into the stomach? There is an instrument that examines the stomach and is inserted. Does it break the fast or not?

Answer : We say that if it contains a medicinal substance that can settle in the stomach, then it breaks the fast. However, if it is merely an instrument, this instrument will not remain in the stomach; it will be withdrawn, because as soon as he looks at the stomach and examines it, he removes the instrument. But if it contains a substance with which it was coated to facilitate its entry, then it breaks the fast. Yes.
