What this chapter covers

• Section 9.1: Initial assessment and pre-endoscopic management

  Upper GI bleeding is a perfusion problem first, a diagnosis problem second, and an endoscopy problem third.

• Section 9.2: Anticoagulant and antiplatelet management in UGIB

  Reversal in UGIB is a balance between two competing risks: ongoing hemorrhage on one side, and the thrombotic event that the anticoagulant was preventing on the other.

• Section 9.3: Forrest classification and endoscopic hemostasis modality

  The Forrest classification ties endoscopic appearance to rebleeding risk and to the intensity of intervention required: The single sentence to fix is that high-risk stigmata (Forrest Ia, Ib, IIa) demand dual endoscopic therapy because the rebleed rate without intervention is high and dual modality reduces it durably, while low-risk stigmata (Forrest IIc, III) require no endoscopic therapy because their rebleed rates are too low to justify it.

• Section 9.4: PPI dosing strategy and rebleeding prevention

  Acid suppression after endoscopic hemostasis is the medical adjunct that turns a successful procedure into durable control.

• Section 9.5: Acute variceal hemorrhage

  Variceal hemorrhage is portal hypertension making itself known through the lowest-resistance escape route in the portosystemic circulation, and management combines three treatments: vasoactive infusion to lower portal pressure, prophylactic antibiotics to prevent infection-driven decompensation, and endoscopic band ligation to stop the active bleed.

• Section 9.6: Non-ulcer non-variceal causes

  The lesions in this section are missed by the standard approach of EGD, PPI, and banding unless they are suspected from the start.

   Variceal Bleeding Care

   Upper GI bleeding is a perfusion problem first, a diagnosis problem second, and an endoscopy problem third, so the first hour follows a fixed order: resuscitate, prepare the stomach, estimate risk, then scope. The episode follows a man with a bleeding duodenal ulcer through restrictive transfusion, pre-endoscopy drugs, risk scoring, Forrest-guided dual therapy, PPI protection, rebleeding, and H. pylori eradication. It then turns to bleeding on blood thinners, where two risks compete, the bleed now and the clot the drug prevented. That covers apixaban, aspirin, warfarin, dabigatran, and a recent stent.

   Upper GI Bleeding: Varices and Hidden Sources

   Variceal bleeding is managed as a bundle that mostly starts before the endoscope, while the other sources in this episode escape the standard approach unless someone suspects them. The episode begins with a cirrhotic man vomiting blood: airway protection, restrictive transfusion, no routine correction of clotting tests, octreotide, ceftriaxone, band ligation within twelve hours, and early covered TIPS in high-risk patients. It then covers tamponade and stent bridges, gastric varices, and secondary prophylaxis. Next come a Dieulafoy lesion, an aortoenteric fistula, GAVE and Cameron lesions, small bowel angiodysplasia with aortic stenosis, and hereditary hemorrhagic telangiectasia, ending with the board traps.
