Introduction

Introduction Esophageal dilation is divided into primary and secondary. The expansion that occurs above the esophageal stricture is a secondary expansion, and the primary expansion is divided into two types: extensive expansion and limited expansion. 1, extensive expansion, also known as congenital expansion, the cause of the disease is unknown, esophageal neuromuscular dysfunction caused by the full esophageal dilation. 2, limited expansion: bulging diverticulum often due to congenital dysplasia of the smooth muscle layer of the esophageal wall, the surface of the mucosal part caused by the bulging of the place, mostly occurred at the junction of the pharynx, esophagus, a small number occurred in the lower esophagus. Traumatic diverticulum often causes scar contraction due to chronic inflammation of the tissues around the esophagus (such as lymph node tuberculosis), which is formed by pulling the esophageal wall, and occurs mostly in the anterior wall of the esophagus.

1, congenital expansion due to the expansion of the esophagus, also known as giant esophageal disease, esophageal neuromuscular dysfunction caused by full esophageal dilation.

2, the limited expansion of the esophagus, that is, diverticulum is often divided into two types of bulging (true) diverticulum and traction (pseudo) diverticulum. The bulging diverticulum protrudes more from the posterior wall, and the sag is sag in front of the spine due to the increase of the diverticulum. Traumatic diverticulum often causes scar contraction due to chronic inflammation of the tissues around the esophagus (such as lymph node tuberculosis), which is formed by pulling the esophageal wall, and occurs mostly in the anterior wall of the esophagus.

Diagnosis

Differential diagnosis

The differential diagnosis of esophageal achalasia and esophageal cancer and cardiac cancer is the most important. The X-ray features of cancerous esophageal stricture are local mucosal destruction and disorder, and the stenosis is moderately dilated. Esophageal achalasia often causes extreme expansion.
