Ultrasonography for the positioning of esophageal multichannel intraluminal impedance/pH‐metry catheter in newborns

Key Points

• Ultrasonography accurately identifies the pH sensor placement and lower esophageal sphincter in newborns.
• Successful real-time assessment of multichannel intraluminal impedance is achieved through ultrasonography.
• Assessment is contingent on the expertise of the ultrasonography operator for reliable results.
• Results indicate ultrasonography may serve as a valid alternative to traditional methods in clinical settings.
