What is the popcorn test?
Some patients think the opening out of the stomach pouch is too small, thus causing them to regurgitate. To differentiate whether the vomiting or regurgitation is due to the patient eating or drinking too fast or the patient not chewing adequately before swallowing versus there being a technical problem, the patient is advised to eat some popcorn. If the patient eats the popcorn with no regurgitation or vomiting, then there is no mechanically obstructive problem with the operation. The patient is eating too fast, chewing inadequately or swallowing large quantities at a time. Popcorn can only be swallowed after chewing well and swallowing small quantities.
