Q: Question: Do transient lower esophageal sphincter relaxations result from passive opening of the cardia by gastric distention?
Answer: These data refute the hypothesis that transient lower esophageal sphincter relaxations result from passive mechanical distraction of the gastroesophageal junction. Rather, transient lower esophageal sphincter relaxations must occur before the gastroesophageal junction can open.
A:
no
