Esophageal Stricture Clinical Presentation

History
- Patients with peptic strictures may present with heartburn, dysphagia, odynophagia, food impaction, weight loss, and chest pain.
- Progressive dysphagia for solids is the most common presenting symptom. This may progress to include liquids.
- Atypical presentations include chronic cough and asthma secondary to aspiration of food or acid.
- The clinician cannot rely on the presence or absence of heartburn to definitely determine whether dysphagia is secondary to a peptic esophageal stricture.
- Of patients with peptic esophageal strictures, 25% have no previous history of heartburn.
- Heartburn may resolve with worsening of a peptic stricture.
- Approximately two thirds of patients with adenocarcinoma in Barrett esophagus have a history of long-standing heartburn.
- The abnormal esophageal motor activity in achalasia can produce a heartburn sensation.
- Important points regarding dysphagia
- The obstruction is usually perceived at a point that is either above or at the level of the lesion.
- Dysphagia for solids and liquids simultaneously should alert the clinician to the possibility of a motility disorder such as achalasia or collagen vascular disorders.
- Dysphagia secondary to a Schatzki ring is usually intermittent and nonprogressive.
- Dysphagia for solids and liquids early in the course of disease should alert the clinician to the possibility of achalasia as an etiology of a peptic esophageal stricture.
- Benign esophageal strictures usually produce dysphagia with slow and insidious progression (ie, months to years) of frequency and severity with minimal weight loss.
- Malignant esophageal strictures result in a rapid progression (ie, weeks to months) of severity and frequency of dysphagia and are associated frequently with significant weight loss.
- Determining whether the patient takes any medications known to cause pill esophagitis is important.
- Determining whether a history of collagen vascular disease or immunosuppression exists may provide clues to the underlying etiology.
Physical
- Physical examination frequently does not provide clues to the cause of dysphagia.
- Assessing the patient's nutritional status is important.
- Patients with collagen vascular diseases may exhibit joint abnormalities, calcinosis, telangiectasias, sclerodactyly, or rashes.
- The presence of atypical gastroesophageal reflux disease may be suggested by hoarse voice, posterior oropharyngeal erythema, diffuse dental erosions, wheezing, or epigastric tenderness.
- Patients with adenocarcinoma of the gastroesophageal junction may have left supraclavicular lymphadenopathy (Virchow node).
Causes
- Proximal or mid esophageal strictures
- Caustic ingestion (acid or alkali)
- Malignancy
- Radiation therapy[3, 4]
- Infectious esophagitis -Candida, herpes simplex virus (HSV), cytomegalovirus (CMV), human immunodeficiency virus (HIV)
- Acquired immunodeficiency syndrome (AIDS) and immunosuppression in patients who have received a transplant
- Medication-induced stricture (pill esophagitis) - Alendronate, ferrous sulfate, nonsteroidal anti-inflammatory drugs (NSAIDs), phenytoin, potassium chloride, quinidine, tetracycline, ascorbic acid.[5] Drug-induced esophagitis often occurs at the anatomic site of narrowing, with the middle one-third behind the left atrium predominating in 75.6%.[6]
- Diseases of the skin - Pemphigus vulgaris, benign mucous membrane (cicatricial) pemphigoid, epidermolysis bullosa dystrophica
- Graft versus host disease
- Idiopathic eosinophilic esophagitis
- Extrinsic compression
- Squamous cell carcinoma
- Sequela of endoscopic submucosal dissection for superficial squamous cell neoplasms.[7]
- Miscellaneous - Trauma to the esophagus from external forces, foreign body, surgical anastomosis/postoperative stricture, congenital esophageal stenosis
- Distal esophageal strictures
- Peptic stricture - Gastroesophageal reflux disease, Zollinger-Ellison syndrome
- Adenocarcinoma
- Collagen vascular disease - Scleroderma, systemic lupus erythematosus (SLE), rheumatoid arthritis
- Extrinsic compression
- Alkaline reflux following gastric resection
- Sclerotherapy and prolonged nasogastric intubation
- Crohn disease
