oral/esophageal/stomach issues Flashcards
Where do esophageal diverticula occur
where there is weakness in the musculature
When will an esophageal diverticular become symptomatic
> 1cm diameter
Where will Zenkers diverticula occur
Killian’s triangle
*bigger in men which is why Zenkers is more common in them
What causes esophageal varices
increased portal pressure
>12mmhg increases bleeding risk of the varices
What are the causes of increased pressure leading to esophageal varices
Specific location in the body
Presinusoidal
sinusoidal
postsinusoidal
Where are esophageal varices most common
Distal esophagus
What is the origin of an upper GI bleed
Cant be below this structure
Ligament of treitz and above
If a GI bleed occurs below the ligament of treitz.. what type of bleed do they have
Lower GI bleed
What is H.Pylori able to suppress
Think of cancer
P53
What inflammatory disorders lead to scar tissue formation
GERD
Frequent emesis
ETOH
Caustic ingestions
Crohns
What does a schatzki ring cause
Sudden reduction in the diameter of the lumen of the esophagus
<13mm will have symptoms
What is a mallory-weiss tear
Where is it most common
longitudinal tear through mucosal layer of the esophagus
lower portion of GE junction
What is generally the cause of mallory-weiss syndrome
Does it go through all layers?
Repeated emesis
NO but the vascular plexus between the layers will bleed
What disorder is achalasia a subtype of
Esophageal dysmotility
*typically associated with a systemic illness
What is achalasia
Autoimmune issue where antibodies attack the myenteric plexus
Eventually leads to obstruction of the lower esophagus
