The effect of selective denervation of the pyloric antrum on secretory response to three types of food was determined in 3 dogs with innervated and 4 with denervated stomach pouches. With the antrum in situ this procedure has surprisingly little effect on the total meal responses in innervated ...
Duodenectomies not only decrease motilin secretion, impacting the contraction of the gastric antrum, but also influences the neuromodulation of the gastrointestinal tract, thereby affecting gastrointestinal motility [9, 10]. Postoperative ischemia or edema of the duodenal stump may represent another ...
2.1Epithelial stem cell compartment The inner surface of the stomach is lined by a mucous membrane known as the gastric mucosa which consists of simple columnar epithelium,lamina propria, andmuscularis mucosae. Due to the severe, acidic conditions in the stomach, gastric epithelial layer undergoes t...
Gastric tumors at distal locations such as the pylorus and antrum were easier to detect via gastroscopy, which comprised 60.9% (67/110) of the cancer group. On the contrary, only 10.9% (12/110) were composed of proximal tumors. More intestinal types of gastric cancer (45.4%, 50/110) by...
The pyloric antrum connects to the stomach's body, leading to the narrower pyloric canal, which further connects to the duodenum. The smooth muscle pyloric sphincter regulates stomach emptying. The stomach wall has 5 layers: Mucosa: This is the innermost layer where nearly all stomach cancers ori...

Differentiated early cancer patients had fewer lesions located in the antrum area (69.8% vs 48.3%, P = 0.006), a larger volume (Z = -40.767, P = 0.006), a greater invasion depth (Z = -76.983, P < 0.001), fewer type 0-I lesions (25.0% vs 3.4%, P < 0.001), and more type 0...
1e). Subsequently, the corpus/antrum region was used as a landmark, and the plasmid mix (diluted in 50 µl of elution buffer; QIAGEN) was injected via a 30-gauge syringe into the epithelial compartment in the corpus region generating a small depot (Extended Data Fig. 1f). Tweezer ...
Muc5ac−/− mice are predisposed to spontaneous antro-pyloric epithelial proliferation that is independent of Hp infection The gastric antrum/pylorus of the experimental mice were scored for inflammation, edema, epithelial hyperplasia, dysplasia, and a cumulative total antral pathology index score was...
(which are more frequent in areas with a lower incidence) have a much poorer prognosis than those with tumors arising in the pyloric antrum (more frequent in areas with a higher incidence), with lower 5-year survival rates and higher operative mortality. In addition, accurate screening for ...
