Recommendations were graded on the strength of the supporting evidence (Grades 1A-3). Definitions of the recommendation grades are presented at the end of the "Major Recommendations" field.

Summary

Barrett's Esophagus (BE)

• The role of endoscopic ultrasonography (EUS) in evaluating patients with BE and high-grade dysplasia (HGD) is to exclude the presence of occult cancer, submucosal invasion, and malignant lymphadenopathy (1C).
• The routine application of EUS in BE with low-grade dysplasia or without dysplasia is not recommended (3).

Esophageal Cancer

• In esophageal cancer, EUS provides accurate locoregional staging that is superior to computerized tomography (CT) scanning (1C+).
• Preoperative EUS staging of esophageal cancer is cost effective and can guide preoperative management (1C+).

Gastric Cancer and Lymphoma

• EUS is useful in the locoregional staging of gastric carcinoma and lymphomas (1C+).
• EUS may be used to monitor response to therapy with disease regression in gastric lymphoma (1C).

Rectal Cancer

• EUS is accurate in the preoperative locoregional staging of rectal cancer (1C+).
• Preoperative EUS staging of rectal cancer is cost effective and can guide preoperative management (1C+).

Submucosal Lesions

• When a submucosal lesion is identified, EUS should be considered to further characterize the lesion (1C).
• EUS-fine-needle aspiration (FNA) or core biopsy can help establish a tissue diagnosis and potentially characterize malignant risk (1C+).
• EUS should be performed before consideration of endoscopic removal of SML (3).

Pancreatic Cancer

• Pancreatic adenocarcinoma can be accurately identified, staged, and diagnosed by EUS and EUS-FNA (1C+).
• Neuroendocrine tumors can be localized and sampled by EUS (3).

Chronic and Acute Pancreatitis

• EUS is the most sensitive imaging study for the detection of structural changes of chronic pancreatitis (1C).
• EUS has been shown to be useful for identifying the presence of bile duct stones in cases of acute gallstone pancreatitis and in selecting patients for endoscopic retrograde cholangiopancreatography (ERCP) at intermediate risk for choledocholithiasis (1C).

Autoimmune Pancreatitis

• EUS, EUS–FNA, and EUS core biopsy can help establish the diagnosis of autoimmune pancreatitis (3).

Pancreatic Cystic Lesions

• EUS is useful for the characterization of the morphology of pancreatic cystic lesions (1C).
• EUS can be used to guide drainage of benign inflammatory lesions (3).

Fecal Incontinence and Perianal Disease

• Internal and external anal sphincter defects can be accurately identified by EUS in the evaluation of fecal incontinence (1C).
• EUS may be used for the identification and characterization of abscesses and perianal fistulae (3).

Choledocolithiasis

• EUS is highly accurate in the detection of choledocolithiasis and has fewer complications than ERCP (1C).

Mediastinal Lymphadenopathy

• EUS-FNA is a safe and accurate method for obtaining a tissue diagnosis in patients with mediastinal adenopathy (1C+).

Lymph Nodes

• Use of EUS and EUS-FNA to differentiate benign from malignant lymph nodes should be considered in patients when results would alter treatment (1C+).

Therapeutic EUS

• EUS-guided celiac neurolysis can provide significant reduction of pancreatic cancer pain (1C).
