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, and the categories, the rebleed rates, and the modality choice for each are worth committing to memory.

• 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 the management bundle is built on three pillars working together: 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 the diagnoses that the EGD plus PPI plus EVL framework misses if the lesion is not in the differential at the start.

Podcast episodes

   Nonvariceal UGIB

   Nonvariceal upper GI bleeding worked as a fixed sequence: perfusion first, diagnosis second, endoscopy third. The first hour moves mortality more than the scope does. Covers resuscitation, transfusion thresholds, pre-endoscopy pharmacology, risk scores, anticoagulant reversal, Forrest-directed endoscopic therapy, and post-hemostasis medical management.

   Variceal and Unusual

   Episode two of the Upper GI Bleeding chapter covers acute variceal hemorrhage and the unusual non-variceal causes a routine scope misses. It anchors on the variceal bundle delivered before endoscopy, early TIPS for the high-risk cirrhotic, and the Sarin split for gastric varices. The second half is a recognition drill: each rare lesion is easy to treat once its history cue is named.
