by reflux of gastric content.
PathophysiologyAntireflux mechanism includes: LES Esophageal peristalsis Resistant of esophageal mucosa. Saliva Gastric peristalsis
![Page 27: APPROACH TO DYSPHAGIA Dr Nahla Azzam Assistant Prof Consultant, Gastroenterology Unit College of Medicine & K.K.U.H. King Saud University](https://reader031.vdocument.in/reader031/viewer/2022032607/56649ed95503460f94be7a26/html5/thumbnails/27.jpg)

· Although the incidence of squamous cell esophageal cancer has decreased over the past two decades in most Western countries and in parts of Asia, including certain high-risk areas of China
· In the 1960s squamous cell esophageal cancers comprised approximately 90% of all esophageal cancers. However, because of an alarming rise in the incidence of esophageal adenocarcinoma, esophageal adenocarcinoma is now the predominant type of esophageal carcinoma in the United States. This reversal pattern has also been recently noted in some European countries such as Denmark and Scotland.
