7

PPI increases the patients risk for ?

10

How do you diagnose pyloric stenosis? Physical exam? US? UGI series?

Physical exam: RUQ olive mass US: thickened & elongated pylorus UGI series: string sign

11

How is diagnosis made with a patient who’s suspicious for achalasia?

(confirm) Esophageal manometry —> increase LES pressure (Initial) Barium swallow —> bird beak appearance (Periop) upper endoscopy—> to r/o malignancy

Schatzki’s rings --> Most common esophageal structural abnormality​

21

what is the first choice for the management of ascites secondary to portal hypertension as a result of cirrhosis?

Spironolactone is an aldosterone antagonist, helping to reverse sodium retention, conserve potassium and achieve diuresis. 

 

you can also  advise your patient to have <2g os sodium per day OR

add furosemide in combination with spironolactone

22

VS

 

 Acids produce a coagulative necrosis that limits further tissue penetration, though perforation can still occur.
