Endoscopic hemostasis in ulcer gastroduodenal bleeding

Gastroduodenal hemorrhages are bleedings in which blood flows from an ulcerated area affected by an inflammatory process with damage to a blood vessel and from where it flows in a stream or drip into the lumen of the gastrointestinal tract. The stomach and duodenum are most often the source of hemorrhage. This is always a formidable complication and a dangerous condition that often poses a threat to life and often ends in death. However, this is not the only variant of internal bleeding with effusion into the gastrointestinal tract: in a number of diseases - varicose veins of the esophagus, nonspecific ulcerative colitis, Crohn's disease, acute intestinal infections, etc. Hemorrhage can occur in various sections of the tract - from the upper esophagus to the rectum - and these conditions must be clearly differentiated from gastroduodenal bleeding. According to various estimates, the cause of gastroduodenal bleeding in 40-70% is gastric ulcer and duodenal ulcer (this also includes drug-induced ulcers, erosive gastritis, etc.). Much less frequently, and with approximately the same frequency, bleeding occurs due to the growth of a malignant tumor in the gastrointestinal tract or varicose veins of the esophageal and gastric veins (liver cirrhosis, portal hypertension syndrome).
