Gastroesophageal reflux disease is a common, recurrent disease with a high risk of complications if not detected and treated aggressively. Gastroesophageal reflux disease is classified into many levels to facilitate the diagnosis and treatment of the disease more effectively..

Surgery in general or esophageal surgery in particular carries the risk of postoperative complications. One of them is the narrowing of the oesophageal junction, making it difficult for patients to eat and drink. Esophageal stricture after surgery can cause dangerous complications if not treated promptly.
