Meta-Analysis Review
20 mg of vonoprazan (VPZ20) is recommended in most countries to treat erosive esophagitis (EE). Whether other doses of vonoprazan, such as 5 mg (VPZ5), 10 mg (VPZ10), 20 mg (VPZ20), and 40 mg (VPZ40) are more effective is unknown. Three databases were electronically searched to identify studies published before November 2021. Network meta-analysis was performed using STATA 14.0. VPZ20 and VPZ40 were comparable to PPI, VPZ5 and VPZ10 in 4- and 8-week healing rates, and this was also detected in patients with refractory EE. All regimens resulted in similar treatment-emergent adverse events (TEAEs). However, VPZ40 ranked first for healing rate and TEAEs; however, VPZ20 ranked worst for TEAEs. Different doses of VPZ are comparable in efficacy and safety, but VPZ40 may be best in both effectiveness and safety.

Review
Esophageal dysmotility is almost universal after esophageal atresia (EA) repair and is mainly related to the developmental anomaly of the esophagus. Esophageal dysmotility is involved in the pathophysiology of numerous symptoms and comorbidities associated with EA such as gastroesophageal reflux disease, aspiration and respiratory complications, and symptoms of dysphagia and feeding disorders. High-resolution esophageal manometry (HREM) has facilitated the characterization of the dysmotility, but there is an incomplete correlation between symptoms and manometrical patterns. Impedance coupled to HREM should help to predict the clinical outcome and therefore personalize patient management. Nowadays, the management of esophageal dysmotility in patients with EA is essentially based on treatment of associated inflammation related to peptic or eosinophilic esophagitis.

Review
Eradication of Helicobacter pylori causes improvement of gastric atrophy and intestinal metaplasia. Gastric acid secretion levels in corpus predominant gastritis increase after eradication. These changes can increase the risk of reflux esophagitis and low-dosage aspirin ulcers. Although eradication may reduce the overall risk of gastric cancer, a certain degree of risk remains, related to the extent of atrophy and intestinal metaplasia. Many post-eradication gastric cancers are the early depressed type, with low levels of epithelial atypia, and therefore can be difficult to distinguish endoscopically from benign erosion. Further research is required in this area.

Review
Obesity is associated with gastroesophageal reflux disease (GERD) and its complications including reflux esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. Traditionally, these associations have been attributed to the mechanical effect of abdominal fat in increasing intra-abdominal pressure, thereby promoting gastroesophageal reflux and causing disruption of antireflux mechanisms at the esophagogastric junction. However, recent studies suggest that visceral adipose tissue (VAT) produces numerous cytokines that can cause esophageal inflammation and impair esophageal mucosal barrier integrity through reflux-independent mechanisms that render the esophageal mucosa especially susceptible to GERD-induced injury. In this report, we review mechanisms of esophageal mucosal defense, the genesis and remodeling of visceral adipose tissue during obesity, and the potential role of substances produced by VAT, especially the VAT that encircles the esophagogastric junction, in the impairment of esophageal mucosal barrier integrity that leads to the development of GERD complications.

Observational Study
The similarities and differences between acute esophageal necrosis and severe reflux esophagitis have not been elucidated. We compared Los Angeles classification Grade C reflux esophagitis, Grade D reflux esophagitis, and acute esophageal necrosis to consider the similarities and differences between acute esophageal necrosis and severe reflux esophagitis.We retrospectively reviewed records of patients who underwent esophagogastroduodenoscopy at a tertiary referral center from January 2012 to December 2019. Data on patients diagnosed as Grade C reflux, Grade D reflux, or acute esophageal necrosis for the first time were extracted for analysis.A total of 213 patients were enrolled in the study, composed of 130 Grade C reflux, 74 Grade D reflux, and 9 acute esophageal necrosis patients. Compared to Grade C reflux patients, Grade D reflux and acute esophageal necrosis patients were more likely to be transfused (P = .013 and P = .011, respectively), to have duodenal ulcers (P = .025 and P = .049, respectively), and to have psychiatric illnesses (P = .022 and P = .018, respectively). Compared to both Grade C and D reflux, acute esophageal necrosis patients were more likely to present with shock (P = .003 and P < .001, respectively), have type 1 diabetes (P = .030 and P = .004, respectively), and present in winter (P < .001 and P < .001, respectively). Significant step-wise differences (Grade C < Grade D < acute esophageal necrosis) were observed in the need for admission (P < .001 and P = .009), coffee ground emesis (P < .001 and P = .022), and stigmata of hemorrhage on endoscopy (P = .002 and P < .001). Admission (P = .003) and coffee ground emesis (P = .003) independently predicted either Grade D reflux or acute esophageal necrosis over Grade C reflux on multivariate analysis.Shock, type 1 diabetes, and winter may predict acute esophageal necrosis, while the need for admission and coffee ground emesis may predict Grade D reflux or acute esophageal necrosis.

Review
Obesity increases gastroesophageal reflux disease through several factors. As a result, Barrett's esophagus, esophageal adenocarcinoma, and gastroesophageal junctional gastric cancer are increasing. Existing studies usually defined obesity by body mass index and analyzed the correlation. Recently, more studies have shown that central obesity is a more important variable in upper gastrointestinal diseases related to gastroesophageal reflux. Studies have reported that weight loss is effective in reducing gastroesophageal reflux symptoms. Obesity also affects functional gastrointestinal diseases. A significant correlation was shown in upper abdominal pain, reflux, vomiting, and diarrhea rather than lower abdominal diseases.

BACKGROUND
Esophageal stricture (ES) is an uncommon clinic entity in pediatrics that may be congenital or acquired in childhood. Acquired noncaustic ES is very rare, and clinical features of affected patients are unknown.
PURPOSE
We aimed to evaluate the clinical findings, and outcomes of patients with acquired noncaustic ES to aid physicians in the early referral of patients to gastroenterologists.
METHODS
The medical data of patients with acquired noncaustic ES who were followed in our gastroenterology clinic between January 2009 and December 2019 were reviewed.
RESULTS
Acquired noncaustic ES was found in 12 of the 4,950 patients (0.24%) who underwent endoscopy during the study period. The main symptoms were dysphagia (58.3%), vomiting (33.3%), and chronic anemia (8.3%). Chronic malnutrition and underweight were found in 66.6% of the patients. The most common etiological factors were radiotherapy, peptic reflux, and achalasia (16.6%, each), while chemotherapy, squamous-cell carcinoma (SC) of the esophagus, eosinophilic esophagitis (EoE), esophageal web, epidermolysis bullosa, and esophageal diverticulum (8.2%, each) were the other etiological factors. Patients with EoE underwent endoscopic bougie dilation in addition to steroid use and elimination diet. Patients with epidermolysis bullosa and esophageal web underwent bougie dilation. Patients with peptic reflux-related ES were initially put on antireflux therapy, but during follow-up, one patient required esophageal replacement with colonic interposition. Patients with radiotherapy-related ES recovered with medical therapy. The patient with initially underwent surgical gastrostomy and tumoral mass excision. The patient then received chemotherapy and radiotherapy and underwent jejunal interposition. Patients with achalasia underwent surgical esophagomyotomy.
CONCLUSION
The presence of solid dysphagia, malnutrition, and an associated disease may alert physicians to the presence of ES.

BACKGROUND
The pathogenesis of gastroesophageal reflux disease (GERD) has not been resolved in detail. Esophageal epithelial cells provide resistance to acidic reflux via several mechanisms, many of which involve buffering acid with bicarbonate and transporting protons. Carbonic anhydrases (CAs) are enzymes that control the acid-base balance by catalyzing the reversible hydration of carbon dioxide to produce bicarbonate and hydrogen ions.
AIMS
We aimed to determine the immunohistochemical expression patterns of CAII, CAIX, and CAXII in the normal esophageal squamous epithelium and in patients with GERD.
METHODS
We evaluated 82 biopsy samples, including 26 with a histologically normal esophagus, 26 with histologically mild esophagitis, and 30 with severe esophagitis. Expression patterns of CAII, CAIX, and CAXII in the esophageal squamous epithelium were determined by immunohistochemical staining.
RESULTS
Cytoplasmic CAII expression was predominantly detected in the upper luminal part of the squamous epithelium and was significantly (p < 0.01) increased in GERD. Expression of CAIX was essentially membranous. The isozyme was constantly present in the peripapillary cells. In the interpapillary areas, clustered expression was observed to emerge and increase significantly (p < 0.01) in esophagitis. CAXII expression was the most abundant of the isozymes and was mainly membranous. In the normal squamous epithelium, CAXII expression was confined to the basal layer; in severe esophagitis, CAXII expression increased significantly in both basal (p < 0.05) and superficial (p < 0.01) halves of the epithelium.
CONCLUSIONS
We demonstrate upregulated expression of CAII, CAIX, and CAXII in GERD. The increase in expression likely contributes to esophageal epithelial resistance to acidic reflux.

Review
Gastroesophageal reflux disease (GERD) is characterized by regurgitation of gastric juices into the esophagus. This has an erosive effect on the mucosa with accompanying symptoms, such as heartburn, acid regurgitation and positional-/exertion--induced chest pain. The associated inflammation in the multi-layered squamous epithelium of the esophagus (esophagitis) can usually be seen macroscopically at gastroscopy and is always possible to demonstrate microscopically as well-characterized changes. GERD is abundant in the adult population in the Western world, and the incidence appears to be increasing. Serious manifestations of GERD include the appearance of esophageal injury (esophagitis) and columnar lined esophagus (Barrett's esophagus) and, in rare cases, peptic stricture. The glandular-transformed (metaplastic) mucosa carries its clinical significance by constituting the basis for continued cell transformation (development of dysplasia), which eventually might lead to esophageal adenocarcinoma (EAC). EAC is an aggressive form of cancer whose incidence continues to increase in particular in the Western part of the world. In this article the potential mechanisms for the development of the metaplastic glandular epithelium and its progression to dysplasia and cancer is reviewed. In addition, recommendations are given on how important signals about future risks can be captured and managed and how these risks can be minimized and preferably prevented.

Review
Over the past 30 years, the prevalence of upper third gastric cancer (GC) and gastroesophageal junction (GEJ) cancer has increased. Total gastrectomy with D2 lymph node dissection is the standard surgical treatment for non-early (T2 or higher) upper third and GEJ cancers, but total gastrectomy often results in post-gastrectomy syndrome (5-50%), consisting of weight loss, dumping syndrome, and anemia. Proximal gastrectomy (PG) has the potential to avoid these postoperative problems by preserving stomach function. However, PG has historically been discouraged by surgeons owing to the high incidence of postoperative reflux esophagitis (20-65%), anastomotic stenosis, and decreased quality of life. In recent years, anti-reflux reconstruction techniques, such as the double flap technique and double-tract reconstruction, have been developed to be performed after PG, and evidence has emerged that these techniques not only reduce the incidence of postoperative reflux esophagitis but also decrease postoperative weight loss and prevent anemia. Prospective studies are underway to determine whether PG with anti-reflux techniques improves patient-reported quality of life. In the present work, we reviewed available evidence for the use of PG for GC and GEJ cancer, including oncologically appropriate patient selection for PG, potential functional benefits of PG over TG, and various types of reconstructions that can be performed after PG, as well as future research on the use of PG.
