Benign esophageal strictures, characterized by fibrotic narrowing of the esophageal lumen, are frequently encountered in clinical practice. Benign esophageal strictures are associated with a multifactorial etiology and may occur across various age and population groups. Common causes of benign esophageal strictures include gastroesophageal reflux disease (peptic stricture), esophageal injury secondary to surgery (anastomotic strictures), radiotherapy, caustic agent ingestion, or endoscopic resection. Benign esophageal strictures are categorized into simple and complex types based on their size, area involved, surface features, extent of luminal narrowing, and margins. Esophageal strictures often present clinically with dysphagia and may lead to severe complications. Regardless of the underlying cause, therapy is aimed at relief of dysphagia and prevention of stricture recurrence. Benign esophageal strictures are commonly treated using endoscopic balloon or bougie dilation, followed by disease-specific approaches to treat underlying inflammation. However, based on the underlying cause, the risk of recurrence of benign esophageal strictures is 10~30%. Therapeutic options for refractory or recurrent esophageal strictures include endoscopic incisional therapy, esophageal stent placement, or intralesional injection of steroids or mitomycin C. The pathophysiology of esophageal strictures is complicated, and thorough understanding and patient cooperation are important for optimal management. Physicians should familiarize themselves with the various dilation strategies available and their application for management of specific types of stenotic lesions. In this article, we review the evaluation and management of patients with esophageal strictures.
