Hemetamesis and Hemetochezia(Acute GI Hemorrhage)

Dr. Wu ShuMing

GI Dept. RenJi Hospital

Five Ways of GI Bleeding

Hematemesis ： vomitting of blood of altered blood （ coffee grounds ） indicates bleeding proximal to ligament of Treitz

Melena ： Tarry stool. Altered （ black ） blood per rectum （ >60ml ）

Hematochezia ： Bright red or maroon rectal ,bleeding implies bleeding beyond Lig.T.*

FOB+ and Iron deficiency anemia

Factors affect the way to manifest

Site of bleeding Speed of bleeding Amount of blood loss Flora of enterocolon

.

Differentiating Upper from Low GI Bleeding

Hematochezia usually represents a lower GI source bleeding

Upper GI lesion may bleed so briskly that blood doesn`t remain in bowl long enough to become melena

Bleeding lesion distal to T Lig.may be either M.or hematochezia, but never manifests hematemesis

Common cause of up GI bleeding

Peptic ulcer ；Gastropathy （ alcohol ， aspirin ， NSAI

Ds ， stress ）；GE varices ； Gastric cancer

Less common cause of up GI bleeding

Esophageal or intestinal neoplam

Esophagitis ； Malloy-weiss tear ，Hemoptysis: Swallowed blood

Anticoagulant fibrinoloytic therapy:

Telangiectases ； aneurysm ； vasculitis ； Dieulafoy ulcer ； AV malformation

Connective tissue disease ；Hemabilia （ biliary origin ； Crohn`s disease ； amylo

idosis , hematological diseases

BENIGN GASTRIC ULCER

The classical presentation of gastric ulcer :with weight loss and indigestion made worse by eati

ng, patients more often describe symptoms that would fit

equally well for duodenal ulcer - investigation with barium meal or (preferably) endoscopy is, of course, appropriate for either. Benign ulcers may occur at any site in the stomach, but are commonest on the lesser curve away from acid-secreting epithelium.

Duodenum Ulcer

The lesion most commonly affecting the duodenum is ulceration, and it is now known that both antral infection with Helicobacter pylori and the presence of gastric acid are virtual prerequisites for it..

GE Varices

A number of cutaneous features (stigmata) may develop in a patient with cirrhosis, and these are important as they aid clinical recognition of chronic liver disease.

Clinical manifestation of GI Bleeding

Abdominal discomfort

Nausea, Hemadynamic change: reduction in blood v

olume (syncope,light-headedness, sweating,therst) or shock

Laboratory changes: HCT, BUN

Hematemesis with other symptoms

Hematemesis with upper abdominal pain Hematemesis with hepatomegly and spleenomegly Hematemesis with jaundice Hematemesis with Skin & mucosa hemorrhage Hematemesis with upper abdominal mass Others: NSAIDs, Stress, Burning, Brain operation,

Trauma, Vomiting

Lab.Examination in Localization & Diagnosis of GI Bleeding Endoscopy Barium Radiographs Angiography Radionuclide imaging

Approach to the patient with acute upper gastrintesttinal hemorrhage

Acute upper Gastrointestinal Hemorrhage Rapid assessment Monitor hemodynamic status

Fluid resuscitation Gastric lavage(?)

self-limited (80%) bleeding (10-20%) Empiric medical therapy

Urgent endoscopy

recurrent hemorrhage

endoscopy Site not localized Localized

further assessment

enteroscopy, radioisotope s scan, angiography,

exploratory surgery

Definitive therapy Definitive therapy

Summary of Acute GI Bleeding

Upper GI source bleeding--Hemetemesis Major upper GI bleding-- Hemetemesis & h

emetochezia The more distant from the rectum, the more

likely that melaena occurs The colon lesion--FOB+ or hemetochezia The small bowl lesion-- melena or hemetoc

hezia

The questions should be posed

Prior bleeding episode? Family history of GI diseases Dose the patient have the illness of ulcer?

Cirrhosis?cancer?bleeding disorder? Alcohol? NSAIDs? Any precedes symptoms or signs?

A, Linear ulcers of Crohn's colitis. B, Mucosa surrounding the ulcers is nodular (cobblestoning).

Shigella colitis. Patchy areas of erythema, spontaneous bleeding, and loss of the normal vascular pattern are evident

Salmonella colitis. Diffuse erythema, spontaneous bleeding, and loss of the vascular pattern with formation of telangiectasi

s are present.

Tuberculosis. Linear ulceration runs circumferentially along the interhaustral septum with tiny satellite ulcerations. This must be distinguished from the longitudinal linear ulcerations s

een in inflammatory bowel disease.

Pseudomembranous (antibiotic-associated) colitis. Numerous elevated yellowish plaques are present on th

e mucosal surface.

Amebiasis. Discrete punched-out ulcers are present i

n the right colon.

Severe acute ulcerative colitis. No vascular pattern is discernible. A severe degree of spontaneous bleeding is present
