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. FOBt 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 1g Hematochezia usually represents a lower GI source bleeding pper 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

BENIGN GASTRIC ULCER The classical presentation of gastric ulcer with weight loss and indigestion made worse by eating 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
