In an 18-year-old male with a small inflammatory polyp found in the lower esophagus but with normal biopsy results and no significant findings on gastroscopy and colonoscopy, the potential health implications are generally low, especially if there are no symptoms of esophageal dysfunction or alarm features such as dysphagia, weight loss, or persistent reflux unresponsive to treatment. The presence of a small inflammatory polyp in the context of possible reflux may reflect benign mucosal irritation rather than a premalignant lesion or a manifestation of eosinophilic esophagitis (EoE) or other significant pathologyNICE CG184.
Risks associated with such polyps are minimal if biopsies are normal, given no evidence of dysplasia or neoplasia. According to NICE guidelines, surveillance or further aggressive investigation is not routinely recommended unless there are high-risk features such as Barrett's oesophagus with dysplasia, significant reflux symptoms refractory to therapy, or additional alarm signsNICE CG184,NICE NG231.
In the context of possible reflux, appropriate management includes optimizing acid suppression therapy, typically with proton pump inhibitors (PPIs) as first-line treatment, which not only controls acid reflux symptoms but can also aid mucosal healingNICE CG184. Given the age and normal biopsies, a conservative approach with symptom management and avoidance of risk factors (e.g., smoking, alcohol, NSAIDs) is advisableNICE CG184.
Follow-up should be guided primarily by clinical symptoms. If the patient is asymptomatic and there is no histological evidence of pathology such as eosinophilic infiltration or dysplasia, routine surveillance endoscopy is not requiredNICE CG184. However, patients with ongoing symptoms of gastroesophageal reflux disease (GERD) should be monitored clinically and possibly re-investigated if symptoms persist or worsen in line with NICE guidanceNICE CG184.
Given the normal biopsy results, eosinophilic esophagitis—a chronic, Th2-mediated inflammatory disease characterized by ≥15 eosinophils per high-power field—is unlikely, but it should be considered in differential diagnoses when symptoms of esophageal dysfunction such as dysphagia or food impaction occurHindy et al. 2025,Domingues et al. 2025,Bertin et al. 2026. Normal biopsies essentially exclude active eosinophilic inflammation and the need for targeted therapies such as swallowed topical corticosteroids or biologics like dupilumabHindy et al. 2025,Domingues et al. 2025.
Therefore, the recommended management focuses on symptomatic treatment of reflux with PPIs, lifestyle modifications, and reassurance. Endoscopic surveillance is reserved for those with pathological findings such as Barrett’s oesophagus or persistent mucosal abnormalities. Repeat biopsy or endoscopy is indicated only if new symptoms develop or if reflux symptoms are refractory to optimized treatmentNICE CG184,NICE NG231.
