pylor-, pyloro-, pylori- +

Posterior pyloromyotomy combined with the Heineke-Mikulicz pyloroplasty (enlargement of a pyloric stricture): A double pyloroplasty is an operation in which a restricted stomach outlet is expanded in order to allow the contents of a stomach to empty into the duodenum.

A surgical operation for the purpose of widening the outlet of the stomach: Finney pyloroplasty is performed in order to enlarge the pyloric canal with the establishment of an inverted U-shaped anastomosis (surgical union of two hollow organs) between the stomach and duodenum after a longitudinal incision.

Excision of the pylorus (opening in a vertebrate from the stomach into the intestine). A gastropylorectomy was necessary for Mr. Smith due to an incurable infection of the pylorus

The enlargement of a pyloric stricture by incising the pylorus longitudinally and suturing the incision transversely: After the Heineke-Mikulicz pyloroplasty was completed and Mrs. Black was recovering, she was very happy that the food she ate could pass through her stomach into the intestine much easier.

Excision of half of the pylorus: Because the elderly Mr. White had a tumor in the lower part of his stomach, a hemipylorectomy had to be performed immediately, and Mr. White underwent the operation very well.

The "pylorus" is a thick muscular ring (sphincter) surrounding the outlet of the stomach into the duodenum.

It closes to prevent unduly large pieces of food from leaving, thus enabling stomach acid and enzymes to break them down further.

Near or around the pylorus or the pyloric part of the stomach; peripyloric: After the doctor examined the elderly Mrs. Dawson, she was informed that she had a juxtapyloric gastric ulcer that was situated close to the pylorus.

Pain in the pyloric region: Because Sam was suffering, particularly in his stomach, he wen to see Dr. Smart, who said that he had a case of pyloralgia in the opening from the stomach into the intestine

The surgical removal, or excision of all or part of the pylorus: Mrs. Green was relieved when the pylorectomy was completed and she was feeling good again, and she was told by the doctor that part of the stomach had to be removed as well.

Relating to the pylorus: The pyloric opening is surrounded by muscular tissue, from the stomach into the duodenum or the first part of the small intestine.

The pyloric distal aperture of the stomach or abomasum, opens into the duodenum.

The term pyloric is used to mean the pyloric part of the stomach, and the pyloric antrum, canal, opening, or sphincter.

A ring of muscles, the pyloric sphincter, serves as a "gate", closing the opening from the stomach to the intestine. It opens periodically, in order to allow the contents of the stomach to move into the duodenum or small intestine.

A rare disorder of the muscle fibers, like the pylorus, failing to relax: A condition of pyloric achalasia causes food to stay trapped in the stomach withoug any blockage or thickening of a muscle.

The initial portion of the pyloric part of the stomach: The pyloric antrum may temporarily become partially or completely shut off from the remainder of the stomach during digestion.

The dilated natural cavity or hollow of the pyloric part of the stomach, is between the body of the pyloric antrum (antrum pyloricum) stomach and the pyloric canal.

The pyloric antrum is the bulging part of the lower end of the stomach between the body of the stomach and the pyloric canal which is near the bottom of the stomach which separates the stomach and the duodenum (small intestine).

A short canal or opening between the stomach and the small intestine: The pyloric canal primarily consists of muscle which can become too narrow, in some circumstances.

When the pyloric canal becomes too narrow, food and liquids may not be able to pass and this can result in symptoms easily feeling full, odorous belching, or nausea and vomiting.

The first part of the duodenum, as seen in a roentgenogram (X-ray) or by fluoroscopy; duodenal bulb: The duodenal cap is the first widened section of the small intestine that links directly to the stomach.

the compression of the pylorus which is he valve-like opening connecting the stomach to the small intestine: Since Joe was having terrible stomach pains, he went to see Dr. Smart who, after examining him thoroughly, told him that he had a pyloric constriction which had to be operated on immediately.

A pyloric constriction is a prominent fold of mucous membrane at the gastroduodenal junction overlying the pyloric sphincter or the thickening of the circular layer of the gastric musculature (stomach muscle) encircling the gastroduodenal junction (place where the stomach and small intestine meet).

Any of several coiled, tubular, mucus-secreting glands situated in the mucus membrane near the pyloric end of the stomach: The pyloric gland produces protective mucus and significant hormone.
