Inflammatory fibroid polyp of the esophagus: a systematic review.

Introduction: Esophageal inflammatory fibroid polyp (IFP) is a rare benign tumor of the gastrointestinal tract with limited available data on clinicopathologic features and treatment strategies.

Evidence Acquisition: A systematic review of the literature in PubMed/Medline and Scopus databases was performed for articles concerning esophageal IFP in adult population.

Evidence Synthesis: A total of 16 studies were identified, involving 16 patients with a Male-Female Ratio of 3:1 and mean age of 50.38 years. Clinical presentation of esophageal IFP included progressive dysphagia in 56.3% of cases, with additional symptoms such as epigastric and retrosternal pain, weight loss, vomiting, and melena. Diagnostic modalities involved endoscopy in all cases, with endoscopic ultrasound (EUS) employed in 50% of cases and tissue biopsy performed during endoscopy in 87.5% of the patients. Therapeutic approach of esophageal IFP consisted of surgical resection in 75% of the patients and endoscopic resection in the remaining 25%, with various surgical procedures employed based on tumor location. Follow-up data, available for 11 patients over a median duration of 15.5 months, indicated two instances of recurrence following endoscopic resection, while the other nine patients remained asymptomatic with no evidence of recurrence.

Conclusions: Esophageal IFP is a rare benign tumor of the gastrointestinal tract presenting with dysphagia, regurgitation, and heartburn. Resection, either endoscopic or surgical, is the primary treatment approach. Prognosis for esophageal IFP is favorable, with low recurrence rates. Further research is required to investigate potential risk factors and etiology for this lesion, and to explore novel therapeutic approaches that may improve patient outcomes.
