Esophageal atresia (EA) is one of the most common congenital digestive malformations and requires surgical correction early in life. Dedicated centers have reported survival rates up to 95%. The most frequent comorbidities after EA repair are dysphagia (72%) and gastroesophageal reflux (GER) (67%). Chronic GER after EA repair might lead to mucosal damage, esophageal stricturing, Barrett’s esophagus and eventually esophageal adenocarcinoma. Several long-term follow-up studies found an increased risk of Barrett’s esophagus and esophageal carcinoma in EA patients, both at a relatively young age. Given these findings, the recent ESPGHAN-NASPGHAN guideline recommends routine endoscopy in adults born with EA. We report a series of four EA patients who developed a carcinoma of the gastrointestinal tract: three esophageal carcinoma and one colorectal carcinoma in a colonic interposition. These cases emphasize the importance of lifelong screening of the upper gastrointestinal tract in EA patients.
Core tip: Esophageal atresia (EA) is a common congenital malformation that requires surgical correction early in life. Improved perioperative care and surgical techniques have increased the survival rate. Gastroesophageal reflux and stasis are common after surgical repair and may be associated with an increased esophageal cancer risk. However, data on incidence and risk factors for esophageal carcinogenesis after EA repair are scarce. The recent ESPGHAN-NASPGHAN guideline recommends routine endoscopy in adults born with EA. Here we report four cancer cases at a relatively young age after EA repair: three esophageal carcinoma and one colorectal carcinoma in a colonic interposition.
