Images show clips in the distal esophagus on the scout radiograph, compatible with the patient's recent Per-oral esophageal myotomy (POEM) procedure.
On the water-soluble images, there was no leak.
On the subsequent barium images, one can see how the lower esophageal sphincter is now wider than with achalasia. On the LPO image, a small amount of barium adheres to the clips, showing their submucosal location.
