pylor-, pyloro-, pylori- +

The strong band of muscle between the stomach and the small intestine.

A narrowing of the pylorus, the opening between the stomach and into the small intestine.

Surgical dilation or expanding the opening of a contracted or tighter pylorus opening.

Relating to or a reference to the pylorus or the opening from the stomach into the intestine and the duodenum (the first part of the intestine).

Inflammation involving the pyloric outlet of the stomach and the duodenum which is the first or proximal part of the small intestine, extending from the pylorus to the jejunum (part of the small intestine), so called because it is about twelve fingerbreadths in length.

The excision of the pylorus (opening from the stomach and the first part of the small intestine) and the connecting part of the stomach.

Longitudinal surgical incision through the anterior wall of the pyloric canal to the level of the submucosa (tissue), to treat hypertrophic pyloric stenosis which is the narrowing of the pyloric canal due to narrowing of the pyloric canal due to muscular hypertrophy (abnormal enlargement) of the surrounding circular muscle.

Pyloric stenosis occurs more often in boys than in girls, and is rare in children older than six months because the condition is usually diagnosed by the time a child is six months old.

1. The surgical alteration to widen the pylorous in order to facilitate the passage of food from the stomach to the duodenum or small intestine.
2. A surgical operation to widen the opening between the stomach and the small intestine, which allows stomach contents to pass more freely from the stomach.

With the patient under anesthesia the pyloric opening is dilated or expanded and diarrhea is a common postoperative complication.

3. An elective surgical procedure in which the lower portion of the stomach, the pylorus, is cut and resutured, to relax the muscle and to widen the opening into the intestine.

Pyloroplasty is a treatment for high-risk patients for gastric or peptic ulcer disease.

A peptic ulcer is a sore on the stomach where the lining of the stomach or duodenum has been eaten away by stomach acid and digestive juices.

The end of the pylorus is surrounded by a strong band of muscle (pyloric sphincter), through which the contents of the stomach are emptied into the duodenum (the first part of the small intestine). Pyloroplasty widens this opening into the duodenum.

Downward displacement (out of position) of the pyloric end of the stomach.

An endoscopic (internal) inspection of the pylorus.

1. A surgical formation of a fistula (opening) from the abdominal surface into the stomach near the pylorus.
2. A surgical opening through the abdominal wall into the stomach near the pylorus.

1. The opening from the stomach into the top of the small intestine or duodenum.
2. The valve which releases food from the stomach into the intestines.
3. The passage at the lower end of the stomach that opens into the duodenum.
4. A muscular or myovascular structure that opens or closes an orifice or lumen of an organ.
