What causes a pyloric ulcer?

Why is it called pylorus?

The orifice is surrounded by a sphincter, a band of muscle, called the pyloric sphincter. The word pylorus comes from Greek πυλωρός, via Latin. The word pylorus in Greek means “gatekeeper”, related to “gate” (Greek: pyle) and is thus linguistically related to the word “pylon”.

What is the difference between pylorus and duodenum?

The duodenum is the first section of the small intestine. Together, the pylorus and duodenum play an important role in helping to move food through the digestive system. The pyloric sphincter is a band of smooth muscle that controls the movement of partially digested food and juices from the pylorus into the duodenum.

What is the stomach area of a horse called?

Basic Anatomy
The equine gastrointestinal tract can be divided into two main sections: the foregut and the hindgut. The foregut consists of the stomach and small intestine while the hindgut or large intestine is made up of the cecum and colon.

How do you fix a pyloric sphincter?

The Heineke-Mikulicz method is the most common type of pyloroplasty performed. The surgeon cuts lengthwise through your pylorus, including the ring of muscle that opens and closes it (the pyloric sphincter). Then they sew it back together with crosswise stitches, widening the diameter and relaxing the muscle.

Can the pylorus be removed?

Pyloroplasty involves cutting through and removing some of the pyloric sphincter to widen and relax the pylorus. This makes it easier for food to pass into the duodenum. In some cases, the pyloric sphincter is entirely removed.
