NBI displays enhanced images of capillaries in the mucosal surface and detailed mucosal texture by irradiating two narrow wave bands (390?445 nm/530?550 nm) which are strongly absorbed by circulating hemoglobin. If signal processing is performed using a pseudo-narrow band image, the state of mucosa tissues and observation conditions influence the results and good effects cannot be obtained. However, with NBI, the wavelength of the irradiating light itself is altered, and capillaries in the mucosal surface and detailed mucosal texture can thus be processed effectively and stably.

Worldwide, stomach cancer (also referred to as gastric cancer) remains one of the most common forms of cancer, affecting approximately 800,000 new individuals annually. However, the rate of stomach cancer has been declining in the United States and western Europe over the past half-century, a trend which has been felt attributable in large part to changes in diet during this period of time. Interestingly, the incidence of cancers located in different portions of the stomach appear to be heading in opposite directions: while those located in the more distal (lower) portion of the stomach have been declining in incidence, there has actually been an increase in cases occurring in the proximal portion of the stomach (closer to the esophagus) and at the gastroesophageal junction.

Stomach cancer is more readily treated when caught early. Unfortunately, by the time it causes symptoms, the disease is often at an advanced stage and may have spread beyond the stomach. Yet there is encouraging news. You can reduce your risk of this serious cancer by making a few changes in your lifestyle.

 Advanced lesions have already invaded the muscularis propria.
 They are associated with metastases to regional lymph nodes or
 to local or distant structures.

 Early gastric lesions are confined to the mucosa or submucosa.
 Most reports are from Japan, as a result of mass screening there.
 Patients with these tumors have a 5-year survival rate of 90%.

 
Gastric Adenocarcinoma. Pathophysiology: The accepted pathway involves transitions from gastritis to gastric atrophy to metaplasia to dysplasia and,finally, to cancer. Several dietary and environmental factors may influence this pathway. Hypochlorhydria: This condition occurs in gastric atrophy and promotes bacterial colonization of the stomach. It leads to increased nitrite formation, which may have a mutagenic effect on the atrophic gastric mucosa.Helicobacter pylori: Antral gastritis caused by H pylori has been linked to the development of gastric cancer. Patients with H pylori gastritis are 3-6 times more likely to develop gastric cancer than individuals without the infection.Certain foods: Starch, pickled vegetables, salted fish and meat, smoked foods, and salt have all been implicated.Cigarette smoking: Those who smoke more than 30 cigarettes per day have a 5-fold increased risk of gastric carcinoma.Several precancerous conditions are recognized: Chronic atrophic gastritis Pernicious anemia Previous partial gastrectomy, Ménétrier disease Gastric dysplasia Adenomatous polyps (20% of all gastric polyps) Hereditary factors.

Another image and video of that small neoplasia, however The cat scan displays that the liver is infiltrated with metastases. CT is primarily used to preoperatively assess patients with gastric carcinoma. CT is to assess the presence and extent of extragastric spread. This information is vital in deciding between palliative surgery and curative radical surgery. Therefore, the main role of CT is to identify patients who would not benefit from radical surgery. Thus, CT is used to stage the tumor and also to monitor the response to treatment.

ALTHOUGH GASTRIC CARCINOMA occurs with reduced frequency, it is still a prevalent disease. Most gastric carcinomas are classified as adenocarcinomas due to glandular growth pattern and/or presumed occurrence of mucin intracellularly Mucin is often identified by periodic acid-Schiff (PAS) and/or alcian blue (AB) positivity. However, neither of these histochemical methods is specific for mucins. Both methods are based upon the identification of glycoproteins. We have previously described that a proportion of gastric carcinomas, particularly of the diffuse type according to Laurén 1965 are neuroendocrine derived and probably of enterochromaffin-like (ECL) cell origin. The so-called signet ring cell carcinomas belong to the diffuse type of gastric carcinomas.

Pathological exams reported a strong connective stroma-reaction associated with a malignant glandular proliferation of independent cells (signet-ring cells), invading all the layers of the digestive tract, the mucosa being usually save not affected.Diagnosis is based on the association of pathological results findings revealed by endoscopic, endoscopic ultrasonography, radiological and surgical examinations. Opposed to the adenocarcinoma, Helicobacter Pylori seems not to be associated with the occurrence of gastric linitis.

Diet appears to play a major role in the development of stomach cancer. Nitroso compounds such as nitrites (found in smoked meats and fish) and nitrates (used in food preservatives), and high salt intake, likely contribute to this disease, whereas fresh vegetables are protective. The question of whether green tea also has any protective effects remains debatable.

A bacteria called Helicobacter pylori represents an additional risk factor for gastric cancer, particularly those cancers occurring in the distal portion (antrum) of the stomach. This infection may lead to inflammation of the superficial layer of the stomach, inducing changes in the cells that line the stomach which eventually results in cancer. It should be stressed, however, that most patients with H. pylori infection do not develop gastric cancer. The independent association between peptic ulcer disease (PUD) and stomach cancer remains questionable, although H. pylori infection is known to be a risk factor for both. Autoimmune gastritis (associated with lack of hydrochloric acid secretion in the stomach and pernicious anemia), and adenomatous gastric polyps, represent other precursors that increase a person's risk of developing stomach cancer. Chronic GERD (gastroesophageal reflux disease) can cause damage to the tissue lining the lower portion of the esophagus and first portion of the stomach (cardia), resulting in the development of cancer at the G-E junction.
