Gatekeeper Channel

Gatekeeper channel

The pyloric canal (Canalis pylorus, PNA; synonyms Pyloric canal, Cardinal canal) is a narrow canal lined with mucous membrane, passing through the thickness of the stomach wall and connecting the stomach with the duodenum. It has a characteristic narrowing during the transition to the pyloroduodenal section of the intestine.

Together with the wall of the stomach, the pyloric canal forms its greater curvature (oblique curvature), the magnitude of which varies individually. The width of the canal of normal patency can be measured transversely only in 2 sections of it in relation to the lengths



**The pyloric canal** is a short canal that connects the stomach to the duodenum. It is part of the human digestive system and is responsible for transporting food from the stomach to the intestines. This canal is also called the pyloric canal because it is located in an area of ​​the stomach called the pylorus.

The pyloric canal is about 3-5 cm long and 8-15 mm wide. It begins at the entrance to the stomach, where the stomach passes into the duodenum, and ends at the border between the stomach and duodenum. The gatekeeper channel has several functions:

1. Transporting food from the stomach to the duodenum. 2. Regulation of the amount of gastric juice entering the intestines. 3. Protection of the intestinal mucosa from the action of hydrochloric acid from the stomach. 4. Removing excess bile and enzymes from food that are not needed in the intestines. 5. Regulation of intestinal motor activity by releasing prostaglandins and other hormones. 6. Accumulation of gastric mucus to protect the stomach lining. 7. Strengthening contact between the stomach, intestines and gallbladder.

The main diseases of the pyloric canal are inflammation, ulcers, tumors, abnormal contractions and malposition. Pyloric canal diseases can cause abdominal pain, nausea, vomiting, loss of appetite, and weight loss. To treat these conditions, your doctor may prescribe medication, surgery, or a combination of medication and surgery.



The Pyloric canal is a narrow canal 7 cm long, extending from the lower part of the stomach, communicating with the large duodenum and opening at the neck of the gallbladder. This process in the form of a triangle in front of the hepatoduodenal ligament has the characteristic name “vesical depression”. In some places, the Pyloric canal forms communications with other parts of the gastrointestinal tract: the omental bursa, the hepatointestinal ligament, the small duodenum and the esophagus.
