“…The European Society of Gastrointestinal Endoscopy recommends that for quality control, eight images should be taken to illustrate the examination of the stomach in its totality (complementary images should be taken in the case of a specific lesion) 78 . Detection of subtle gastric mucosal changes during examination requires the use advanced endoscopic techniques, such as narrow-band imaging (NBI) with or without magnification (NBI-ME), which has high sensitivity and specificity 78, 79 . NBI endoscopy may also help in assessing the extent of the lesions, and in improving safety margins and cure rates during endoscopic resection of EGC.…”

Synopsis Gastric Cancer (GC) is 3rd leading cause of cancer related death worldwide; only 28.3% of are expected to survive >5 years. Although GC incidence has declined in the US during the last decade, an increase in the incidence of GC has been estimated for 2016. GC risk factors include, male gender, having >60 years, infectious agents such as H. pylori, GC family history, certain occupations, tobacco use, and diet, among others. Prognosis of GC is largely dependent on the tumor stage at diagnosis and classification as intestinal or diffuse type, which has worse prognosis. Although promising chemoprevention agents have been reported to decrease GC risk, none have been implemented into clinical practice to date. Risk assessment and surveillance guidelines have been implemented in Asian countries with high incidence of GC, whereas in the US, only the American Society for Gastrointestinal Endoscopy has recently published guidelines for the screening and management gastric lesions. Importance of diagnosis of GC at an early stage is imperative since 5 year survival rates can approximate 90% in this setting.

“…Endoscopy with optic image magnification and NBI allows the assessment of the network of fine blood vessels, which correlates well with histopathological findings and increases the possibility of early differentiation of gastric polyps already during endoscopy; dense distribution of irregular capillaries on the polyp surface is characteristic of GHPs[31]. …”

Gastric polyps become a major clinical problem because of high prevalence and tendency to malignant transformation of some of them. The development of gastric hyperplastic polyps results from excessive proliferation of foveolar cells accompanied by their increased exfoliation, and they are macroscopically indistinguishable from other polyps with lower or higher malignant potential. Panendoscopy allows detection and differentiation of gastric polyps, usually after obtaining histopathological biopsy specimens. Unremoved gastric hyperplastic polyps may enlarge and sometimes spontaneously undergo a sequential progression to cancer. For this reason, gastric hyperplastic polyps larger than 5 mm in size should be removed in one piece. After excision of polyps with atypical focal lesion, endoscopic surveillance is suggested depending on histopathological diagnosis and possibility of confirming the completeness of endoscopic resection. Because of the risk of cancer development also in gastric mucosa outside the polyp, neighboring fragments of gastric mucosa should undergo microscopic investigations. This procedure allows for identification of patients who can benefit most from oncological endoscopic surveillance. If Helicobacter pylori (H. pylori) infection of the gastric mucosa is confirmed, treatment strategies should include eradication of bacteria, which may prevent progression of intestinal metaplasia. The efficacy of H. pylori eradication should be checked 3-6 mo later.

The endoscopic finding of a gastric polyp and the histopathologic report that follows may leave clinicians with questions that have not been addressed in formal guidelines: do all polyps need to be excised, or can they just be sampled for biopsy? If so, which ones and how many should be sampled? What follow-up evaluation is needed, if any? This review relies on the existing literature and our collective experience to provide practical answers to these questions. Fundic gland polyps, now the most frequent gastric polyps in Western countries because of widespread use of proton pump inhibitors, and hyperplastic polyps, the second most common polyps notable for their association with gastritis and their low but important potential for harboring dysplastic or neoplastic foci, are discussed in greater detail. Adenomas have had their name changed to raised intraepithelial neoplasia and are decreasing in parallel with Helicobacter pylori infection; however, they do retain their importance as harbingers of gastric cancer, particularly in East Asia. Gastrointestinal stromal tumors have low incidence and no known associations, but their malignant potential is high; early diagnosis and proper management are crucial. Although rare and benign, inflammatory fibroid polyps need to recognized, particularly by pathologists, to avoid misdiagnosis. Gastric neuroendocrine tumors (carcinoids) are important because of their association with either atrophic gastritis or the multiple endocrine neoplasia syndromes; those that do not arise in these backgrounds have high malignant potential and require aggressive management. The review concludes with some practical suggestions on how to approach gastric polyps detected at endoscopy.
