In addition, gastric lavage can actually push the gastric contents beyond the pylorus, which enhances absorption. |
|
A septum of connective tissue separates the circular muscle layers of the pylorus and duodenum. |
|
The muscle of the pylorus does, however, show the high degree of myogenic tone characteristic of other sphincters. |
|
If it is exactly in the midline, it may be the duodenal bulb, the pylorus, or the distal antrum. |
|
All gastric operations involving vagotomy included the breach of the pylorus, usually by pyloroplasty. |
|
A clear catheter entered the stomach at the gastrostomy site and had passed the pylorus into the duodenum. |
|
This illustrates the essential place of the closure of the pylorus by tonic contraction in the prevention of such reflux. |
|
Unless a duodenal switch is performed to lessen absorption, the pylorus and small intestine remain intact. |
|
They are virtually absent from both the mynenteric plexus and the circular muscle layer in the cardia and fundus, rising to a maximal density at the level of the pylorus. |
|
As these signs may be absent where numerous tests convincingly demonstrate pylorospasm, we must conclude that there is no essential interrelation between obstruction at the pylorus and hyperkinesis. |
|
It is believed that babies who develop the condition are not born with pyloric stenosis, but that the progressive thickening of the pylorus occurs after birth. |
|
In patients with simple gastroenterostomy, an attempt was first made through pylorus. |
|
It begins at the pylorus, the juncture with the stomach, and ends at the ileocecal valve, the juncture with the colon. |
|
The internal surface of the pylorus is covered with a mucous-membrane lining that secretes gastric juices. |
|
It is horizontal, passing backward and to the right from the pylorus, and lies somewhat behind the wide end of the gallbladder. |
|
It is only partially effective in emptying gastric contents and may propel pills beyond the pylorus. |
|
The esophagus, antrum, pylorus, and duodenum were unremarkable. |
|
Three antral biopsies were obtained within 2-5cm from the pylorus. |
|
The opening of the pylorus after it has contracted may represent, in part, the dilating effect of the contraction of the longitudinal muscle layer of the stomach. |
|
The former includes the fundus and the rostral two-thirds of the corpus, while the latter constitutes the rest of the corpus, the antrum, and the pylorus. |
|
|
It increases lower esophageal sphincter tone, stimulates contractions of smooth gastric muscles and at the same time relaxes the pylorus and duodenum. |
|
The term pylorus is used to refer to the pyloric sphincter and can also be applied to that portion of the stomach immediately above the pyloric sphincter. |
|
The main functions of the pylorus are to prevent intestinal contents from reentering the stomach when the small intestine contracts and to limit the passage of large food particles or undigested material into the intestine. |
|
Another series of experiments was conducted involving rat models where ulcers were induced by acetic acid, pylorus ligation, prednisolone, reserpine and restraint. |
|
Located between the pylorus and the caecum. |
|
The stone was palpable and visible through the pylorus, and an anterior gastrotomy was performed in the antrum. |
|
Histopathological examination of the GI tract revealed capillary congestion and some extravasation of erythrocytes in the superficial mucosa of the fundus and pylorus in both treated and control dogs. |
