all patients with cirrhosis screened for what? screened for esophageal varices with EGD
esophageal varices that flatten with air insufflation during endoscopy Small varices that are usually less than 5 mm in diameter
esophageal varices that persist despite air insufflation during endoscopy Large varices are larger than 5 mm
red wale markings (longitudinal red streaks on varices) indicates what? what to do for these pts? varices at inc risk of rupturing; next step - nonselective β-blockers or ligation as ppx to prevent variceal hemorrhage. If ligation doesn't work->balloon tamponade->TIPS (portal decompression by placement of transjugular intrahepatic portosystemic shunt)
recently acute diverticulitis - how to treat? what to do once resolved? Uncomplicated, acute diverticulitis should be treated 7-10 days using broad-spectrum abx; Following resolution, the entire colorectum should be evaluated to rule out other disorders that may mimic diverticulitis, such as adenocarcinoma or Crohn disease.

What to do if on EGD, if a non-bleeding visible vessel is found in an ulcer? An ulcer with a visible vessel has an approximately 50% risk of rebleeding. These ulcers can be effectively treated with injection of sclerosants, thermal coagulation via endoscopic probes, or mechanical modalities such as hemostatic clips.
