Esophageal varices seven days after banding, showing ulceration at the site of banding The upper two thirds of the esophagus are drained via the esophageal veins , which carry deoxygenated blood from the esophagus to the azygos vein , which in turn drains directly into the superior vena cava .
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 ...
A treatment used sometimes is endoscopic band ligation. [27] In 2010, a team of Japanese surgeons performed a "novel endoscopic ablation of gastric antral vascular ectasia". [10] The experimental procedure resulted in "no complications". [10] Relapse is possible, even after treatment by argon plasma coagulation and progesterone. [21]
Banding is a medical procedure which uses elastic bands for constriction. Banding may be used to tie off blood vessels in order to stop bleeding, as in the treatment of bleeding esophageal varices. [1] The band restricts blood flow to the ligated tissue, so that it eventually dies and sloughs away from the supporting tissue.
Portal hypertension is defined as increased portal venous pressure, with a hepatic venous pressure gradient greater than 5 mmHg. [3] [4] Normal portal pressure is 1–4 mmHg; clinically insignificant portal hypertension is present at portal pressures 5–9 mmHg; clinically significant portal hypertension is present at portal pressures greater than 10 mmHg.

Complications of the disorder include stricture of the esophagus, which can lead to food bolus obstruction, and weight loss. Treatment of lymphocytic esophagitis includes medications meant to target the esophagus topically, such as budesonide, but also procedures to deal with complications, such as esophageal dilation.
The esophageal balloon should not remain inflated for more than six hours, to avoid necrosis. The gastric lumen is used to aspirate stomach contents. [citation needed] Generally, Sengstaken–Blakemore tubes and Minnesota tubes are used only in emergencies where bleeding from presumed varices is impossible to control with medication alone.
Gastric varices are dilated submucosal veins in the lining of the stomach, which can be a life-threatening cause of bleeding in the upper gastrointestinal tract.They are most commonly found in patients with portal hypertension, or elevated pressure in the portal vein system, which may be a complication of cirrhosis.
