ASGE Guidelines

ASGE evidence-based guidelines provide clinicians with recommendations for the evaluation, diagnosis, and management of patients undergoing endoscopic procedures of the digestive tract. Guidelines are not a substitute for physicians’ opinion on individual patients. Final decision on an intervention should always be based on local expertise and patient preferences.

All recommendations follow a rigorous process based on a systematic review of medical literature as outlined by the National Academy of Medicine (formerly Institute of Medicine) standards for guideline development.

Whenever possible, guidelines are based on the GRADE (Grading of Recommendation Assessment, Development and Evaluation) methodology.

Panels consist of content experts, stakeholders from other specialties, patient representatives, and members of the ASGE Standards of Practice (SOP) Committee.

Each recommendation is based on consideration of the best medical literature, the balance between risks and benefits, cost-effectiveness, patients’ values, and equity.

Panel members provide ongoing conflict of interest (COI) disclosures, including intellectual conflicts of interest, throughout the development and publication of all guidelines in accordance with the ASGE Policy for Managing Declared Conflicts of Interests.

ASGE strives to provide clinically relevant and practical recommendations, which can help standardize patient care and improve outcomes.

The role of endoscopy in subepithelial lesions of the GI tract

Sep 28, 2017, 11:28 AM
Subepithelial lesions (SELs) of the GI tract are tumors that originate from the muscularis mucosa, submucosa, or muscularis propria. The term subepithelial lesion is preferred to the term submucosal tumor, which should be reserved for those that originate from the submucosal layer. SELs are most commonly found in the stomach, as often as 1 in every 300 endoscopies.2 They usually are identified during routine upper and lower endoscopy as rounded protuberances with normal overlying mucosa. The majority are small (<2 cm in diameter) and found incidentally; however, SELs can present with bleeding, obstruction, or metastases, depending on tumor size, location, and histopathology.

Quality in Endoscopy

Quality documents define the indicators of high-quality endoscopy and how to measure it. ASGE quality indicators are based on a rigorous review process which results in valid metrics for evaluating GI endoscopic procedures.
