Guidewire-assisted placement of water-perfused esophageal high-resolution manometry probe when gastric insertion fails: A single-center experience.

In cases of inability to traverse the EGJ, insertion of a water-perfused HRM probe using an endoscopically-placed nasogastric guidewire allows successful EGJ and esophageal peristalsis assessment. Although motility disorders are often suspected using alternative diagnostic modalities, guidewire-assisted placement of HRM may be helpful for revealing them in patients where alternative diagnostic modalities are either unavailable or inconclusive.
