Evaluation of Plummer-Vinson syndrome in pediatric patients with dysphagia

Aim: In our study, after excluding all other causes of dysphagia in the pediatric age, we tried to present the patients who were followed up and treated with the diagnosis of Plummer-Vinson syndrome(PWS) with iron deficiency anemia and dysphagia. Our aim is to emphasize that there may be dysphagia that can only be cured with anemia treatment and that it can be improved with treatment by a pediatrician. Material method: Pediatric patients who applied to our hospital with the complaint of dysphagia between May 2019-November 2020 were included in the study. After excluding all other causes of dysphagia, patients diagnosed with PWS were evaluated retrospectively. It was aimed to evaluate the age, gender, type, characteristics and duration of dysphagia of the patients retrospectively and to present them in the light of the literature. Results: PWS was detected in 24 of 200 pediatric patients who presented with dysphagia. The proportion of male patients was 37.5%, and their mean age was 97 months. The mean duration of dysphagia complaints was 11.2 months. Four patients had difficulty swallowing liquid food only, 12 patients had solid swallowing difficulties, and 8 patients had difficulty swallowing both solid and liquid food. Anemia was diagnosed by performing a complete blood count and having hemoglobin and hematocrit levels below 2 standard deviations appropriate for age; Those with vitamin B12 levels below 200 pg/ml were defined as cobalamin deficiency. Esophageal web was detected in 4 patients who underwent contrast esophagography. In esophagogastroduodensoscopy, stenosis was treated endoscopically in patients with web. In 20 patients, dysphagia did not persist after six months of iron deficiency anemia treatment. Conclusion: Although the diagnosis of PVS is rare in children, it should be considered and treated in all children with dysphagia associated with iron deficiency anemia. Patients whose complaints continue after treatment at the appropriate dose and duration should be referred for pediatric gastroenterology evaluation.
