Treatment of GERD complications (Barrett’s, peptic stricture) and extra-oesophageal syndromes

Abstract

Apart from typical reflux symptoms and oesophagitis, the clinical presentation of GERD can be dominated by mucosal complications of reflux (Barrett's oesophagus, oesophageal adenocarcinoma, Peptic structure) or by extra-oesophageal syndromes, most notably asthma, laryngitis, or chronic cough. Managing these entities is much less straightforward than with oesophagitis. With respect to adenocarcinoma, metaplasia and dysplasia are recognised precursors, but the potential of these lesions to evolve to cancer has not been shown to lessen as a result of treatment, medical or surgical. Consequently, management focuses on strategies to identify and eliminate high-grade dysplasia and intramucosal cancer, lesions that are potentially curable by endoscopic ablation or surgical resection. With respect to the extra-oesophageal GERD syndromes, these are increasingly recognised as multifactorial conditions with reflux as an exacerbating factor. Treatment trials have been generally disappointing and the clinical challenge remains in accurately identifying afflicted patients who might benefit from more intensive medical or surgical reflux treatment.
