Is pulling black stomach bleeding?

Lag black stool is not necessarily gastric bleeding, first of all to rule out dietary interference factors, such as whether there is a history of taking animal viscera and blood products, whether there is iron, after excluding interference factors, check stool occult blood positive, suggesting that there may be gastric bleeding, also may be small intestine bleeding, or large intestine distal bleeding. When the condition is relatively stable, improve endoscopic examination as soon as possible to clarify the bleeding situation. If necessary, minimally invasive hemostatic treatment under endoscope can be performed, such as titanium clip hemostasis or electrocoagulation hemostasis. Pay attention to colonoscopy or enteroscopy. During intestinal preparation, closely monitor the patient's blood pressure and heart rate, be alert for massive bleeding. If the bleeding continues to be unrelieved, interventional hemostasis can be performed, or surgical hemostasis can be performed.
