## Direct answer

Upper gastrointestinal bleeding, defined proximal to the ligament of Treitz, presents with haematemesis and melaena and is managed by a fixed pathway: vigorous resuscitation with large-bore access, restrictive transfusion at a haemoglobin threshold of about 7 g/dL in stable patients, risk scoring with the Glasgow-Blatchford score, then endoscopy within 24 hours of presentation once stabilised. Endoscopic haemostasis with combined adrenaline injection plus a mechanical or thermal modality treats high-risk ulcers, stratified by the Forrest classification from a spurting artery to a clean base, followed by high-dose proton pump inhibitor infusion. Variceal bleeding adds terlipressin and prophylactic antibiotics with endoscopic band ligation, balloon tamponade as a temporising bridge, and transjugular intrahepatic portosystemic shunt or surgery for failures; massive lower gastrointestinal bleeding is investigated by colonoscopy, CT angiography or tagged red cell scanning depending on activity.

## What you must remember

- Melaena can follow as little as 50–100 mL of upper bleeding, and haematochezia with instability suggests a brisk upper source; resuscitation precedes diagnosis, transfusing at a haemoglobin threshold of about 7 g/dL in stable patients.
- Glasgow-Blatchford score (haemoglobin, urea, pulse, systolic pressure, syncope, melaena, cardiac or liver disease) identifies patients for outpatient management at a score of 0–1; the Rockall score adds endoscopic findings to predict mortality.
- Endoscopy within 24 hours in stable patients and immediately after resuscitation in unstable active bleeders; intravenous erythromycin before endoscopy improves gastric views.
- Forrest classification of ulcer bleeding: Ia spurting, Ib oozing, IIa visible vessel, IIb adherent clot, IIc pigment spots, III clean base — rebleed risk falls from top to bottom.
- High-dose PPI after endoscopic haemostasis of high-risk ulcers is commonly given as 80 mg bolus followed by 8 mg per hour for 72 hours.
- Variceal pathway: terlipressin plus antibiotics such as ceftriaxone, endoscopic band ligation, balloon tamponade (Sengstaken-Blakemore or Minnesota) for no more than about 24 hours as a bridge to definitive therapy.
- Massive lower GI bleeding: CT angiography for active bleeding (detects around 0.5 mL/min), tagged red blood cell scintigraphy for slower intermittent bleeding (detects around 0.1 mL/min per classical teaching), with colonoscopy after preparation when stable.

## Common confusion

The exam traps you into endoscoping an unstable patient. Endoscopy follows, not precedes, restoration of perfusion — except variceal bleeding after vasoactive drug cover, where early endoscopy within 12 hours is standard. A second confusion is treating a clean-based ulcer (Forrest III) with an infusion and repeat endoscopy: it needs no endoscopic therapy at all.

## Exam-focused takeaway

Learn the pathway as a flow: resuscitate, score, scope, treat, re-treat. Score questions contrast Glasgow-Blatchford (pre-endoscopy, outpatient triage) with Rockall (mortality prediction). Forrest class matching (Ia spurting vessel) and the PPI regimen (80 mg bolus, 8 mg/h, 72 hours) are direct-recall marks. Variceal questions pair terlipressin with antibiotics and band ligation; the tamponade tube is a bridge, never therapy. For obscure recurrent bleeding, remember capsule endoscopy for the small bowel.

## Frequently asked questions

### How is an upper GI bleed defined and why does it matter?
Bleeding proximal to the ligament of Treitz; most such bleeds settle or are controlled endoscopically, so the pathway centres on resuscitation and endoscopy rather than urgent surgery.

### Which score decides outpatient management of upper GI bleeding?
The Glasgow-Blatchford score, which uses only clinical and laboratory variables; a score of 0–1 identifies very low-risk patients suitable for outpatient endoscopy.

### What do you do for an ulcer with a visible vessel?
Combined therapy — adrenaline injection plus clips or a thermal method — followed by high-dose proton pump inhibitor infusion, as visible vessels carry high rebleeding risk.

### When is balloon tamponade used in variceal bleeding?
As a temporary bridge for uncontrolled bleeding despite pharmacotherapy and banding, for a maximum of about 24 hours, pending definitive transjugular intrahepatic portosystemic shunt or surgery.
