Overview

The exact pathogenesis of [disease name] is not fully understood.

OR

It is thought that esophageal stricture is the result of lower pressure of esophageal sphincter in gastroesophageal reflux disease, esophageal motor disorder, inflammation and fibrosis and scar of esophagus  scarry esophagus and esophageal anastomosis strictures.

OR

[Pathogen name] is usually transmitted via the [transmission route] route to the human host.

OR

Following transmission/ingestion, the [pathogen] uses the [entry site] to invade the [cell name] cell.

OR

[Disease or malignancy name] arises from [cell name]s, which are [cell type] cells that are normally involved in [function of cells].

OR

The progression to [disease name] usually involves the [molecular pathway].

OR

The pathophysiology of [disease/malignancy] depends on the histological subtype.

Pathophysiology

Pathogenesis

• The exact pathogenesis of [disease name] is not fully understood.

OR

• It is thought that esophageal stricture is the result of lower pressure of esophageal sphincter in gastroesophageal reflux disease, , esophageal motor disorderor, [hypothesis 3]. inflammation and fibrosis and scar of esophagus  scarry esophagus and esophageal anastomosis strictures.all possible variations of scarry esophageal strictures according their etiology, localization and the extension Histologically, the mucosal epithelium and lamina propria had regenerated as in the normal area. In the EBD group, the circumferential stricture site showed marked thickening, and there were hypertrophic scars associated with epithelial defects on the luminal surface. Histologically, defects of the mucosal epithelium and full-thickness proliferation of connective tissue were observed.

Genetics

• [Disease name] is transmitted in [mode of genetic transmission] pattern.
• Genes involved in the pathogenesis of [disease name] include [gene1], [gene2], and [gene3].
• The development of [disease name] is the result of multiple genetic mutations.

Associated Conditions

• The most important conditions/diseases associated with esophageal stricture include:
  • gastroesophageal reflux disease

Gross Pathology

• On gross pathology, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].

Microscopic Pathology

• On microscopic histopathological analysis, [feature1], [feature2], and [feature3] are characteristic findings of [disease name].

Normal physiology:

Gastric acid frequently get back as reflux to esophagus. Lower esophageal sphincter normally prevent large amount of gastric acid reflux. The esophagus normally has the ability to clear gastric acid effect by normal esophageal peristalsis.
