The basic differences between esophageal and gastric varices are the layers in which the varicose veins form: the lamina propria mucosae and submucosa in the esophageal varices and the submucosa in gastric varices.

Normally, a muscular valve at the lower end of the esophagus, the lower esophageal sphincter (LES), keeps the acid solution in the stomach and out of the esophagus. Smoking decreases the strength of the LES, thereby allowing stomach acids to reflux, or flow backward into the esophagus.

Venous pressure is the vascular pressure in a vein or the atria of the heart. It is much lower than arterial pressure, with common values of 5 mmHg in the right atrium and 8 mmHg in the left atrium. ... Portal venous pressure or the blood pressure in the portal vein. It is normally 5–10 mmHg.

Your body carries blood to your liver through a large blood vessel called the portal vein. Cirrhosis slows your blood flow and puts stress on the portal vein. This causes high blood pressure known as portal hypertension.

However, the two blood vessels are quite different from each other in terms of function. One of the major difference between arteries and veins is that the arteries carry oxygenated blood to all body parts, whereas veins carry the deoxygenated blood to the heart.

The main difference between pharynx and larynx is that pharynx is a part of an alimentary canal, which extends from the nasal cavity and mouth to the larynx and the esophagus whereas larynx is the upper portion of the trachea. Both air and food pass through the pharynx.

Vascular lesions of the small intestine are common causes of gastrointestinal hemorrhage. Arteriovenous malformations (AVMs) are an important vascular cause of gastrointestinal bleeding. An AVM is most often located in the cecum and right side of the colon; however, AVMs of the small intestine are rare.

Ulcers. A peptic ulcer is a sore on the lining of your stomach, small intestine or esophagus. A peptic ulcer in the stomach is called a gastric ulcer. A duodenal ulcer is a peptic ulcer that develops in the first part of the small intestine (duodenum). An esophageal ulcer occurs in the lower part of your esophagus.

Veins begin to dilate and swell as a result of increased blood flow. Cirrhosis is the most common cause of portal hypertension. Cirrhosis is a severe scarring of the liver that often develops due to excessive alcohol consumption or serious infections, such as hepatitis.

The esophagus is the hollow tube that leads from the throat (pharynx) to the stomach. Food does not just fall through the esophagus into the stomach. The walls of the esophagus propel food to the stomach by rhythmic waves of muscular contractions called peristalsis.

When the upper GI tract is coated with barium, the radiologist is able to view and assess the anatomy and function of the esophagus, stomach and duodenum. An x-ray examination that evaluates only the pharynx and esophagus is called a barium swallow or esophagram.

There are three types of peptic ulcers: gastric ulcers, or ulcers that develop in the stomach lining. esophageal ulcers, or ulcers that develop in the esophagus. duodenal ulcers, or ulcers that develop in the duodenum (small intestine)

Hepatitis C and cirrhosis of the liver are medical conditions that can damage and inflame the liver. Hepatitis C is a viral illness, while cirrhosis is scarring of the liver that can occur due to hepatitis C and other medical conditions.

The swollen veins are known as esophageal varices. Esophageal varices may leak blood and eventually rupture. This can lead to severe bleeding and life-threatening complications, including death. When this happens, it's a medical emergency.

Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure that may be used to reduce portal hypertension and its complications, especially variceal bleeding. A TIPS procedure may be done by a radiologist, who places a small wire-mesh coil (stent) into a liver vein.
