It can be caused by or associated with gastroesophageal reflux disease, [1] esophagitis, a dysfunctional lower esophageal sphincter, disordered motility, lye ingestion, or a hiatal hernia. Strictures can form after esophageal surgery and other treatments such as laser therapy or photodynamic therapy. While the area heals, a scar forms, causing ...
Esophageal endoscopic ultrasound can provide staging information regarding the level of tumor invasion, and possible spread to regional lymph nodes. The location of the tumor is generally measured by the distance from the teeth. The esophagus (25 cm or 10 in long) is commonly divided into three parts for purposes of determining the location.
SEMS are used to treat additional complications of cancer, such as tracheoesophageal fistulas from esophageal cancer, [8] and gastric outlet obstruction from stomach, duodenal, or pancreatic cancer. [9] SEMS and self-expanding plastic stents have also been used for non-malignant conditions that cause narrowing or leaks of the esophagus or colon.
The stricture is about 3 to 5 mm in diameter. The blood that is visible is from the endoscope bumping into the stricture. Esophageal stricture, or narrowing of the esophagus, is usually a complication of acid reflux, most commonly due to gastroesophageal reflux disease (GERD). These patients are usually older and have had GERD for a long time.
Esophageal dysphagia: Lumen Impacted foreign body; Wall: Esophageal atresia; Benign strictures, due to reflux esophagitis, swallowed corrosives, tuberculosis, and radiotherapy, scleroderma/systemic sclerosis; Spasms, due to achalasia, Paterson-Kelly syndrome, esophageal webs, and esophageal rings; Neoplasms, such as esophageal cancer ...
Barrett's esophagus is the dominant pre-malignant lesion of esophageal adenocarcinoma, [18] and has prevalent epigenetic alterations. [19] Esophageal squamous-cell carcinomas may occur as second primary tumors associated with head and neck cancer, due to field cancerization (i.e. a regional reaction to long-term carcinogenic exposure).
For benign esophageal disease such as refractory esophageal strictures, plastic stents are available. Common complications include chest pain, overgrowth of tissue around the stent and stent migration. [citation needed] Esophageal stents may also be used to staunch the bleeding of esophageal varices.

Later manifestations of caustic substance ingestions include esophageal strictures or stenosis; which can result in chronic pain and malnutrition. [1] Esophageal strictures more commonly occur after more severe mucosal injury, occurring in to 71% and 100% of grade 2b and 3 mucosal lesions respectively. [2]
