Essential practice guidelines & consensus statements with global applicability in the field of endoscopy.

Proposal of minimum elements for screening and diagnosis of gastric cancer by an international Delphi consensus (February 2022)

The World Endoscopy Organization Stomach and Duodenal Diseases Committee extracted minimum elements for screening and diagnosis of gastric cancer (GC) in aim to support countries that do not have national guidelines on screening and diagnosis of GC. Current national or international guidelines were collected worldwide and recommendations were classified according to the quality of evidence and were finalized through a modified Delphi method. The minimum elements consist of seven categories: [1] Extraction of high-risk patients of GC before esophagogastroduodenoscopy (EGD), [2] Patients who need surveillance of GC, [3] Method to ensure quality of EGD for detection of GC, [4] Individual GC risk assessment by EGD, [5] Extraction of high-risk patients of GC after EGD [6] Qualitative or differential diagnosis of GC by EGD, and [7] Endoscopic assessment to choose the therapeutic strategy for GC. These minimum elements will be a guide to promote the elimination of GC among countries with a high incidence of GC who lack national guidelines or screening programs.

Resuming Endoscopy During COVID-19 Pandemic: ESGE, WEO and WGO Joint Cascade Guideline for Resource Limited Settings
(April 2021)

The cascade adaptations presented here are in conjunction with return strategies reported previously, and which mainly include pre-screening and risk stratification based on questionnaires and temperature meseaurement. Strategies for multiple use of PPE, especially N95 masks and water-resistant longsleeved gowns, have also been descirbed, and may form an important part of return strategies in resource-poor regions.


WEO Guidance to Endoscopists: Reopening of Endoscopy Services (May 2020)

This update from the WEO COVID-19 Response Taskforce includes additional resources and guidance for reopening endoscopy services in areas where the number of new COVID-19 cases has begun to level off rather than continuing in a sharp upward trajectory and, there is easing of restrictions.


Practical Advice for Management of IBD Patients during the COVID‐19 Pandemic: A World Endoscopy Organization Statement (May 2020)

COVID‐19 is rapidly spreading worldwide and specific literature how to deal with IBD patients is limited so far. Here, the World Endoscopy Organisation (WEO) is providing practical advice for the management of IBD patients during the pandemic covering the diagnostic and therapeutic spectrum.


WEO recommendations on digestive endoscopy and the COVID-19 pandemic (Update 9 April 2020) 

The WEO COVID-19 Response Taskforce endeavors to keep the endoscopy community updated as to advances and guidelines that they may find useful in their practices. This update includes additional options in the recommendations and an updated reference list of guidelines and papers.


WEO recommendations on digestive endoscopy and the COVID-19 pandemic (March 2020)

The World Endoscopy Organization (WEO) recommends endoscopists adhere to local advisories and institutional guidelines for infection control. The following WEO recommendations are intended to provide guidance to endoscopists as they seek to optimize practice in their endoscopy centers as local conditions allow.


Principles and practice to facilitate complete photodocumentation of the upper gastrointestinal tract: World Endoscopy Organization position Statement (2019)

This World Endoscopy Organization (WEO) position statement aims to provide practical guidance to practitioners to carry out complete EGD photodocumentation. Hence, an international group of experts from the WEO Upper GI Cancer Committee formulated the following document using the body of evidence established through literature reviews, expert opinions, and other scientific sources. The group acknowledged that although the procedure should be feasible in any facility, what is needed to achieve a global shift on the concept of completeness is a common written statement of agreement on its potential impact and added value. This best practice statement offers endoscopists principles and practical guidance in order to carry out complete photodocumentation from the hypopharynx to the second duodenal portion.


WEO position statement on hygiene in digestive endoscopy: Focus on endoscopy units in Asia and the Middle East (2016)

The aim of this position statement is to reinforce the key points of hygiene in digestive endoscopy. The present article details the minimum hygiene requirements for reprocessing of endoscopes and endoscopic devices, regardless of the reprocessing method (automated washer-disinfector or manual cleaning) and the endoscopy setting (endoscopy suite, operating room, elective or emergency procedures).


Guidelines for designing a digestive disease endoscopy unit: Report of the World Endoscopy Organization (2013)

A dedicated digestive disease endoscopy unit is structurally and functionally differentiating rapidly as a result of increasing diagnostic and therapeutic possibilities in the last 10–20 years. Publications with practical details are scarce, imposing a challenge in the construction of such a unit. A WEO working group discussed and outlined a practical approach for design and construction of a modern endoscopy unit. Designing the layout is extremely important, necessitating thoughtful planning to provide comfort to the endoscopy staff and patients, and efficient data archiving and transmission.


WEO/WGO Guidelines on endoscope disinfection: a resource-sensitive approach (2011)

Large, comprehensive reviews of transmission of infection during endoscopy have demonstrated that when currently accepted reprocessing practices are followed (in the absence of faulty equipment), there have been no reported episodes of transmission of infection. The fundamental importance of this document is that it represents a truly international consensus of over 150 gastroenterology and digestive endoscopy societies around the world, committed to a simple, uniform, and comprehensive standard to maximize compliance. A particularly novel aspect of the present guideline is the “cascade” concept, which attempts to reconcile a “gold standard” for endoscope reprocessing with a “minimum standard” for areas with more limited local resources.


Recommendations for the ethical performance of Live Endoscopy Demonstrations (2009)

Live demonstrations are traditional and popular methods of teaching practical digestive endoscopy, however criticisms have been expressed that patients may be at disadvantage by agreeing to examination by a visiting specialist, perhaps using unfamiliar equipment and in abnormal circumstances. WEO is strongly in favor of teaching by live demonstration, but believes that the safety and dignity of the patient is paramount.


Position statement for credentialing & quality assurance in endoscopy (2009)

WEO convened a working party to develop guidelines to help healthcare institutions in ensuring high quality endoscopic care. Chaired by Dr Douglas Faigel and Dr Peter Cotton, the working party of interested endoscopists from around the world sought to create international standards for credentialing and quality assurance. The resultant London WEO position statement was presented to the World Congress of Gastroenterology in London, on 25 November 2009, and published in the Journal Endoscopy in December, 2009. The position statement provides guidance on granting and renewal of privileges, determination of competency, and quality assurance and improvement.


Paris endoscopic classification of superficial neoplastic lesions: esophagus, stomach, and colon (2002)

An intensive workshop designed to explore the utility and clinical relevance of the Japanese endoscopic classification of superficial neoplastic lesions of the GI Tract resulted in the Paris classification. This report summarizes conclusions of the workshop and proposes a general framework for the endoscopic classification of superficial lesions of the esophagus, stomach and colon. The clinical relevance of this classification is demonstrated in tables that show the relative proportion of each subtype in the esophagus, stomach and colon, assessing the risk of submucosal invasion and the risk of lymph node metastases.
