Endoscopic optical coherence tomography as a tool to evaluate successful myotomy after a peroral endoscopic myotomy
Optical coherence tomography (OCT) provides imaging depth down to 3 mm and resolution of 7 μm over a 6-cm length over a 90 second scan. It is used to analyze tissue microstructure to scan for any potential abnormalities in the esophagus. As of now, the utility of OCT in assessing the esophageal muscular layers in achalasia patients after a peroral endoscopic myotomy (POEM) procedure has not been assessed. We present a case in which this device was used for this indication.
