 | | A nasogastric tube may be inserted to confirm that the source of the bleeding is the upper gastrointestinal tract, but up to 15% of patients will have a false negative aspirate, usually because of pyloric spasticity or occlusion preventing duodenal bleeding from refluxing into the stomach. |
 | | We recommend endoscopy in all patients with an upper gastrointestinal bleed, despite suggestions in the literature that endoscopy might be withheld or delayed in certain populations, such as young adults with improving symptoms and without further bleeding. |
 | | However, repeat therapy carries a higher risk of complications, especially perforation, so we tend to avoid a repeat endoscopy in patients with a persistent massive gastrointestinal bleed, a large ulcer, or an ulcer in a hard-to-reach location, like the curve between the duodenal bulb and the second portion of the duodenum. |
