Upper gastrointestinal bleeding affects around 50 to 150 people per 100,000 a year. It represents over 50% of cases of gastrointestinal bleeding. [ 2 ] A 1995 UK study found an estimated mortality risk of 11% in those admitted to hospital for gastrointestinal bleeding.
Upper gastrointestinal bleeding then is reported, and is very commonly represented in elderly patients. [4] Black or bloody stools and hematemesis account for over three quarters of the case presentations. Abdominal pain, nausea, vomiting, and unstable vital signs are common.
Hemosuccus pancreaticus is a rare entity, and estimates of its rate are based on small case series. [1] [2] It is the least frequent cause of upper gastrointestinal bleeding (1/1500) and is most often caused by chronic pancreatitis, pancreatic pseudocysts, or pancreatic tumors. [3] As a result, the diagnosis may easily be overlooked. [4]
Mallory–Weiss syndrome is a condition where high intra-abdominal pressures causes laceration and bleeding of the mucosa called Mallory-Weiss tears. [1] Additionally, Mallory–Weiss syndrome is one of the most common causes of acute upper gastrointestinal bleeding, counting of around 1-15% of all cases in adults and less than 5% in children.
Gastrointestinal bleeding from the upper tract occurs in 50 to 150 per 100,000 adults per year. [8] It is more common than lower gastrointestinal bleeding which is estimated to occur at the rate of 20 to 30 per 100,000 per year. [2] Risk of bleeding is more common in males and increases with age. [2]
Patients with portal hypertensive gastropathy may experience bleeding from the stomach, which may uncommonly manifest itself in vomiting blood or melena; however, portal hypertension may cause several other more common sources of upper gastrointestinal bleeding, such as esophageal varices and gastric varices. On endoscopic evaluation of the ...
Forrest's classification is instrumental when stratifying patients with upper gastrointestinal hemorrhage into high and low risk categories for mortality.It is also a significant method of prediction of the risk of rebleeding and very often is used for evaluation of the endoscopic intervention modalities.

Gastric antral vascular ectasia (GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [1] [2] The condition is associated with dilated small blood vessels in the gastric antrum, which is a distal part of the stomach. [1] The dilated vessels result in intestinal bleeding. [3]
