Objective: To explore the value of endoscopic narrow-band imaging in the diagnosis of early-stage esophageal cancer and precancerous lesions in Kazakh patients.
Methods: A total of 106 Kazakh patients with esophageal mucosa lesions diagnosed by routine endoscopy in our hospital from January 2014 to July 2016 were enrolled in this analysis with 30 randomly selected patients with normal endoscopic findings of the esophageal mucosa as the control group. The morphological changes of papillary capillary loop (IPCL) of the esophageal epithelium in the two groups were observed by narrow-band imaging magnifying endoscopy. Pathological examinations were performed for all the patients with esophageal mucosa lesions.
Results: In patients with esophageal mucosa lesions, 10 were diagnosed to have early esophageal cancer, 16 had low-grade tumors, 11 had high-grade tumors and 69 had esophagitis. IPCL typing results showed IPCL type I in all the control subjects, predominantly type IV in patients with early esophageal carcinoma, type II and III in patients with low-grade tumor, type III in patients with high-grade tumor, and type II in patients with esophagitis.
Conclusion: The location and size of the esophageal lesions can be observed clearly by narrow-band imaging magnifying endoscopy. The histopathology of the esophageal mucosa can be analyzed with IPCL classification for diagnosis of early esophageal cancer and precancerous lesions in Kazakhs.

The integrity of esophageal epithelial cells in patients with gastroesophageal reflux disease (GERD) or GERD-like symptoms is the first mechanism of protection to decrease the sensitivity to gastric reflux and heartburn symptoms. We investigated the protective effects of Poliprotect (PPRO), a CE-marked medical device, on esophageal epithelial integrity using in vitro and ex vivo models. In vitro, the protective effects of PPRO were tested on Caco-2 cells.

Introduction: The performance of a high quality esophagogastroduodenoscopy (EGD) is dependent on the mucosal cleanliness. Recently, the Polprep: Effective Assessment of Cleanliness in EGD (PEACE) scale was created to assess the degree of mucosal cleanliness during EGD. The aim of this study was to validate this scoring system in a cohort of international endoscopists.

Background: Eosinophilic esophagitis (EoE) has been described as a chronic allergen/immune-mediated disease characterized by symptoms of esophageal dysfunction and eosinophilic infiltration of the mucosa.
Summary: Over the past decades, EoE has been increasingly recognized in various geographical areas with a high socioeconomic development (mostly industrialized countries) and has evolved from an unknown to a clinically distinct disease with increasing prevalence and incidence. An average age at diagnosis between 30 and 50 years and a male predominance have been consistently observed.

Acute esophageal necrosis (AEN) is an uncommon endoscopic finding characterized by a patchy or diffuse circumferential black pigmentation of the esophageal mucosa, corresponding to ischemic necrosis. It usually presents with upper gastrointestinal bleeding and is thought to be caused by a systemic low blood flow in patients with predisposing risk factors, like advanced age and cardiovascular comorbidities. After initial hemodynamic stabilization, diagnosis is established by esophagogastroduodenoscopy (EGD) with careful biopsies and histological evaluation.
