Management of Bleeding Through a Nasogastric (NG) Tube

Initial Assessment and Management

Perform urgent endoscopic evaluation within 24 hours, with earlier endoscopy for high-risk patients with hemodynamic instability, as recommended by the National Comprehensive Cancer Network 1

Consider upper endoscopy as the first diagnostic step when blood is present in NG aspirate, according to Alimentary Pharmacology and Therapeutics 2

For bleeding gastric varices identified on endoscopy, cyanoacrylate injection is the treatment of choice, as stated by Clinical Gastroenterology and Hepatology 3
Consider balloon-occluded retrograde transvenous obliteration (BRTO) if a gastrorenal shunt is present, as recommended by Clinical Gastroenterology and Hepatology 3
Transjugular intrahepatic portosystemic shunt (TIPS) may be used when there is significant inflow from the coronary vein, according to Clinical Gastroenterology and Hepatology 3

Consider external beam radiation therapy for chronic blood loss due to gastric cancer or radiation-induced damage, as suggested by the National Comprehensive Cancer Network 1
Formalin application may be effective for radiation-damaged tissues, according to Alimentary Pharmacology and Therapeutics 2

After successful hemostasis, monitor for rebleeding through the NG tube, as recommended by the National Comprehensive Cancer Network 1

NG tube insertion should be avoided for three days after acute variceal bleeding, according to Gut 4
Only fine bore tubes should be used in patients with recent variceal bleeding to minimize trauma, as stated by Gut 4
Long-term NG tubes should be changed every 4-6 weeks, alternating nostrils to prevent complications, according to Gut 4
Consider gastrostomy or jejunostomy feeding if enteral nutrition is required for more than 4-6 weeks, as recommended by Gut 4

NG tube-related complications include nasopharyngeal discomfort, nasal erosions, sinusitis, and rarely esophageal damage, according to Gut 5
Monitor for tube displacement, which occurs in approximately 25% of cases, as stated by Gut 5

Consider timing of reintroduction of antithrombotic therapy in consultation with the service that initiated the therapy, as recommended by Gastroenterology 6
