Schatzki ring. location?
Ring at the GE junction.
Schatzki ring. CP?

Schatzki ring. diagnosis?
barium, narrow lumen.
EGD
Schatzki ring. treatment?
Mechanical dilation using bougie or balloon dilators
Plummer. CP?
dysphagia, anemia (iron deficiency), webs
esophageal cancer
Plummer. diagnosis?
barium swallow
Plummer. treatment?
iron. then dor EGD and biopsy (screen).
If cancer –> esophagectomy
Zenker’s. mechanism?
Cause: upper esophageal sphincter dysfunction and esophageal dysmotility increased intraluminal pressure above the cricopharyngeus muscle eventually results in herniation of the mucosa through an area of weakness –> posterior herniation between the fibers of cricopharyngeal muscle.
Impaired cricopharyngeal relaxation
A pulsion, not traction pseudodiverticulitis
