Presentation and endoscopic resection technique of neonatal esophageal choristoma: A case report

BACKGROUND Esophageal choristoma is an exceptionally rare congenital non-malignant mass which may present with a range of symptoms and severity according to size, growth and location. CASE SUMMARY In this article, we describe the case of a 12-day-old patient with an esophageal choristoma. The patient presented to the hospital with intermittent episodes of protrusion of unidentified tissue through the mouth, along with apneic episodes and failure to thrive. The mass was subsequently identified as originating from the upper esophagus. Given the mass size and the severity of symptoms, a decision was made to perform a complete endoscopic mucosal resection, the first procedure of its kind. The intervention was successful, with no complications, and the infant achieved full recovery. The endoscopic approach chosen for this case is presented in detail along with the existing literature on the presentation and treatment of similar cases. CONCLUSION Endoscopic mucosal resection is feasible and curative in neonatal esophageal symptomatic masses.
