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.

If you have any questions or suggestions, please contact Customer Support at Info@asge.org.

The following information is intended only to provide general information and not as a definitive basis for diagnosis or treatment in any particular case. It is very important that you consult your doctor about your specific condition.

The role of endoscopy in the staging and management of colorectal cancer

Nov 14, 2016, 20:27 PM
Colonoscopy has an important role in the localization of malignant lesions for subsequent identification at the time of surgery. Preoperative endoscopic marking can be helpful in localizing flat, small, or subtle colonic lesions that may be difficult to identify by inspection or palpation during surgery. Marking techniques currently available include endoscopic tattooing and metallic clip placement.5-7 Tattoos with India ink are visible at surgery for up to 5 months.5 No guidelines exist on the optimal placement of tattoos or metallic clips; therefore, close communication with surgical colleagues involved in the subsequent resection is important.

Technology Assessments

Technology evaluations provide a review of existing, new, or emerging endoscopic technologies that have an impact on the practice of GI endoscopy. Evaluations are based on a literature review and a search of the MAUDE (U.S. Food and Drug Administration Center for Devices and Radiological Health) database to identify the reported adverse events of a given technology. When financial guidance is indicated, the most recent coding data and list prices at the time of publication are provided.
