  • if impacted —> extracted endoscopically
51
Q

How do we dx and tx esophageal rings?

A
  1. Dx: barium swallow (esophagogram)
  2. Tx: dilation (bougie dilator) or small endoscopic electrosurgical incision; PPIs for heartburn
52
Q

What is the problem in Achalasia?

A
  • propulsion problem
  • Loss of peristalsis (distal 2/3) and failure of deglutitive LES relaxation
  • denervation of the esophagus resulting primarily from loss of nitric oxide-producing inhibitory neurons (ganglion cells) in the myenteric plexus
53
Q

What are the two types of Achalasia?

A
  1. Primary (Idiopathic)
    1. loss of ganglion cells within the esophageal myenteric plexus
