Oesophageal adenocarcinoma following gastric band surgery in two patients

Abstract

Oesophageal adenocarcinoma following gastric band surgery has only been reported three times previously. The incidence is higher in morbidly obese patients, and its pathogenesis is correlated to reflux-induced microenvironmental changes. Bariatric surgery is transformative and its potential benefit for a substantial population is huge. Although no causal relationship with bariatric procedures has been evidenced to date, symptoms of adenocarcinoma—particularly anorexia, weight loss and dysphagia—can easily be overshadowed by alterations in eating patterns associated with weight-loss procedures. We report two cases of oesophageal adenocarcinoma in patients who had undergone a gastric banding procedure, and invite readers to consider the role that pre- and post-operative acid reflux dynamics may have precipitating neoplastic disease, and how endoscopic surveillance may play a role in prevention.
