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. For more information, see the American Society for Gastrointestinal Endoscopy clinical practice guideline development policy and checklist.

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 the management of patients with diarrhea

Nov 14, 2016, 20:27 PM
Diarrheal illnesses can be associated with significant morbidity and mortality, especially in high-risk populations such as the very young, the elderly, and those with comorbid medical illnesses. Diarrhea is defined in adults by abnormal stool weight (O200 g/day), consistency (loose or liquid), and/or frequency (O3 times/day).2,3 A 4-week symptom duration is generally considered as a cutoff point to distinguish acute (%4 weeks) from chronic (O4 weeks) diarrhea.2,3 Because the causes of acute and chronic diarrhea are often different, the need, threshold, and timing of endoscopic evaluation for acute versus chronic diarrhea are different. This document describes the role of endoscopy in the management of patients with diarrhea, with separate discussions for immunocompetent and immunocompromised patients, and is an update of a previous ASGE guideline.4 There are few indications for endoscopy in the management of acute diarrhea, and, although these are briefly discussed, the document primarily focuses on the evaluation on chronic diarrhea.

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.
