<prompt> Answer this question truthfullyWhat is the cause of esophageal stricture?  <response>: <reason> Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated. There are no life-threatening causes of esophageal stricture, however complications resulting from untreated esophageal stricture is common.Esophageal stricture may be caused by: Gastroesophageal reflux disease Caustic ingestions Radiation therapy for thoracic or head and neck tumors Esophageal cancer Congenital causes such as rings and webs Nasogastric intubation Less common causes of esophageal stricture include:Esophageal sclerotherapy Eosinophilic esophagitis Lymphocytic esophagitisDyskeratosis congenita DC Rare dermatologic diseases eg, epidermolysis bullosa dystrophica Mediastinal fibrosis due to tuberculosis or idiopathic fibrosing mediastinitis Drug -induced stricture: Aspirin and anti-inflammatory medications Tetracycline Doxycycline Clindamycin Bisphosphonates Potassium chloride Quinidine preparations Iron compounds Emepronium Alprenolol PinaveriumInfectious esophagitis Candida Herpes simplex virus HSV Cytomegalovirus CMV Human immunodeficiency virus HIVTracheoesophageal fistula repair and esophageal stricture at the anastomosis Esophageal diverticula Increased level of gastric acid exposure to esophageal tissue, for example: Systemic sclerosis Zollinger-Ellison syndrome Nasogastric tube placement Heller myotomy for achalasia Cardiovascular No underlying causes ChemicalPoisoning Caustic ingestion Dental No underlying causes Dermatologic Dyskeratosis congenita DC, epidermolysis bullosa dystrophica Drug Side Effect Drug -induced stricture: Aspirin and anti-inflammatory medications Tetracycline Doxycycline Clindamycin Bisphosphonates Potassium chloride Quinidine preparations Iron compounds Emepronium Alprenolol Pinaverium Ear Nose Throat No underlying causes Endocrine Zollinger-Ellison syndrome, Environmental No underlying causes Gastroenterologic Gastroesophageal reflux disease, Eosinophilic esophagitis, Esophageal diverticula, Zollinger-Ellison syndrome, Systemic sclerosis Genetic No underlying causes Hematologic No underlying causes Iatrogenic Previous surgery on the esophagus, Radiation therapy for thoracic or head and neck tumors, Esophageal sclerotherapy, Tracheoesophageal fistula repair, Nasogastric tube placement, Heller myotomy for achalasia Infectious Disease Infectious esophagitis Candida Herpes simplex virus HSV Cytomegalovirus CMV Human immunodeficiency virus HIV MusculoskeletalOrthopedic No underlying causes Neurologic No underlying causes NutritionalMetabolic No underlying causes ObstetricGynecologic No underlying causes Oncologic No underlying causes Ophthalmologic No underlying causes OverdoseToxicity No underlying causes Psychiatric No underlying causes Pulmonary Mediastinal fibrosis due to tuberculosis or idiopathic fibrosing mediastinitis RenalElectrolyte No underlying causes RheumatologyImmunologyAllergy Systemic sclerosis Sexual No underlying causes Trauma No underlying causes Urologic No underlying causes Miscellaneous No underlying causesList the causes of the disease in alphabetical order.Caustic ingestionsDrug -induced stricture Dyskeratosis congenita DC Eosinophilic esophagitis Esophageal diverticula Esophageal sclerotherapy Gastroesophageal reflux disease Increased level of gastric acid exposure to esophageal tissue Infectious esophagitis Mediastinal fibrosis due to tuberculosis or idiopathic fibrosing mediastinitis Nasogastric intubation Radiation therapy for thoracic or head and neck tumors Rare dermatologic diseases eg, epidermolysis bullosa dystrophica Tracheoesophageal fistula repair and esophageal stricture at the anastomosis
