Four cancer cases after esophageal atresia repair: Time to start screening the upper gastrointestinal tract

引用

World Journal of Gastroenterology 2018年第9期24卷 1056-1062页

作者： Floor WT Vergouwe Madeleine Gottrand Bas PL Wijnhoven Hanneke IJsselstijn Guillaume Piessen Marco J Bruno René mh Wijnen Manon CW Spaander Department of Gastroenterology and Hepatology Erasmus MC University Medical Center Department of Pediatric Surgery Erasmus MC University Medical Center - Sophia Children's Hospital Department of Pediatrics Jeanne de Flandre Children’s Hospital - Univ.Lille CHU Lille Department of Surgery Erasmus MC University Medical Center Department of Digestive and Oncological Surgery Claude Huriez Hospital - Univ.Lille CHU Lille

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.
