RESUMO
Esophagogastric junction outflow obstruction (EGJOO) is a rapidly evolving diagnosis that can represent early or variant achalasia. Since the publication of the Chicago Classification version 4.0, the criteria for this diagnosis have been more stringent. Currently, the criteria include an elevated median integrated relaxation pressure (IRP) in both the supine and upright positions, elevated intrabolus pressure in at least 20% of supine swallows, dysphagia and/or chest pain, as well as an abnormal timed barium esophagram and/or impedance planimetry testing. Additionally, other secondary causes may result in an elevated IRP and must be excluded. The management of conclusive EGJOO is targeted therapy to the lower esophageal sphincter (LES), although treatment is not straightforward. Overall, adjuvant testing and data should be scrutinized for appropriateness of LES disruption. The spectrum of treatment options includes simple monitoring as well as more invasive therapies such as endoscopic dilation and myotomy. This article explores the newest criteria and management options for clinically relevant EGJOO.
RESUMO
Barrett's esophagus is a premalignant condition portending increased risk of esophageal adenocarcinoma. Given the significant morbidity and mortality of esophageal adenocarcinoma, identification of risk factors for Barrett's esophagus and esophageal adenocarcinoma is crucial. There are a plethora of studies investigating the relationship of obesity with these pathologies. Recent studies reveal that this relationship may specifically be with central adiposity. Increased cell turnover and eventual carcinogenesis is likely precipitated by increased intragastric pressure but also is affected by the complex interplay of increased insulin resistance in patients with increased fat tissue. Further studies are warranted to evaluate if weight loss can decrease progression of Barrett's esophagus.
