BACKGROUND: Endoscopic ultrasonography (EUS) has evolved over the past 20 years with the emergence of novel diagnostic and therapeutic indications. Our goal was to identify the best evidence supporting the use of EUS. MATERIALS AND METHODS: A six-step approach was employed to develop recommendations using accepted methodology. Twenty-two experienced endosonographers identified topics and reviewed studies using MeSH (medical subject headings) terminology and free text in PubMed. Medline and society abstracts were reviewed if necessary. The quality of evidence, the strength of recommendations, and level of consensus were graded and voted on. RESULTS: Consensus was reached for several clinical scenarios for which the impact of EUS findings was supported by a high level of evidence. These included diagnosis and staging of esophageal cancer, differential diagnosis of subepithelial lesions, thickened gastric folds, assessment of peritoneal involvement in patients with gastric cancer, mucosa-associated lymphoid tissue lymphoma, diagnosis of common bile duct/gallbladder stones, diagnosis of chronic pancreatitis, differential diagnosis of a solid mass in patients with chronic pancreatitis, differential diagnosis of pancreatic cyst, rectal cancer staging, and diagnosis and staging of non-small-cell lung cancer. The recommendations were adopted by the Brazilian Society of Gastrointestinal Endoscopy. Several indications continue to emerge and require additional validation. Georg Thieme Verlag KG Stuttgart.
