Overview
Malignant esophageal strictures are narrowing of the esophagus caused by malignancies, leading to dysphagia and potential complications such as reflux esophagitis. Effective palliation often involves stent placement to relieve symptoms 1.Diagnosis
Endoscopic visualization of stricture
Barium swallow to assess stricture location and severity
Biopsy to confirm malignancy 1Management
First-line Treatment: Placement of self-expandable metallic stents (SEMS) for palliation 1
Adjunctive Measures: Use of SEMS with antireflux mechanisms to reduce reflux esophagitis 1Special Populations
No specific data provided for pregnancy, pediatrics, elderly, or comorbidities in the given abstracts 1.Key Recommendations
Consider placement of SEMS with an antireflux mechanism in patients with unresectable malignant gastroesophageal strictures to effectively palliate symptoms and prevent reflux esophagitis (Evidence: Moderate) 1
Monitor patients post-stent placement for signs of reflux using pH monitoring when feasible (Evidence: Weak) 1
Evaluate the need for SEMS without antireflux mechanisms cautiously, given higher incidence of reflux complications (Evidence: Moderate) 1References
