Patient Perspective on Safety of Elective Gastrointestinal Endoscopy During the COVID-19 Pandemic.

BACKGROUND: Patients' perception regarding the risks of COVID-19 infection with gastrointestinal (GI) and the preventive measures taken in GI endoscopy units to mitigate infection risk remains unclear. We aimed to assess patients' perception regarding risks of COVID-19 with GI endoscopy and the changes in the endoscopy unit as a result of the ongoing pandemic. METHODS: Outpatients undergoing GI endoscopy at our institution were categorized into those scheduled to undergo GI endoscopy (preprocedure) and those who had recently undergone GI endoscopy during the pandemic (postprocedure). Two separate but similar survey instruments were designed. Patients were asked to respond on a 5-point Likert scale. Responses were stratified as "low," "neutral," and "high" for analysis. RESULTS: A total of 150 and 355 respondents completed the preprocedure and postprocedure surveys, with a combined response rate of 82.5%. Non-white ethnicity was associated with reporting a "high" level of concern for endoscopy related COVID-19 exposure in both the preprocedure (OR 4.09, 95% CI 1.54-10.82) and postprocedure cohorts (OR 2.11, 95% CI 1.04-4.29). 42% of patients in the preprocedure cohort and 11.8% in the postprocedure cohort reported their level of concern for COVID exposure as "high." Among the postprocedure cohort, 88% of the patients were likely to undergo repeat endoscopy during the pandemic if recommended. CONCLUSION: Patients are willing to undergo GI endoscopy during the COVID-19 pandemic. Non-white and older patients, and those undergoing screening examinations were more concerned with the GI endoscopy related COVID-19 transmission risk.

Biopsy channel of the endoscope as a potential source of infectious droplets during GI endoscopy.

BACKGROUND AND AIMS: During endoscopy, droplets with the potential to transmit infectious diseases are known to emanate from a patient's mouth and anus, but they may also be expelled from the biopsy channel of the endoscope. The main goal of our study was to quantify droplets emerging from the biopsy channel during clinical endoscopy. METHODS: A novel light-scattering device was used to measure droplets emanating from the biopsy channel. An endoscopy model was created, and in vitro measurements were carried out during air insufflation, air and water suctioning, and the performance of biopsy sampling. Similar measurements were then made on patients undergoing endoscopy, with all measurements taking place over 2 days to minimize variation. RESULTS: During in vitro testing, no droplets were observed at the biopsy channel during air insufflation or air and water suctioning. In 3 of 5 cases, droplets were observed during biopsy sampling, mostly when the forceps were being removed from the endoscope. In the 22 patients undergoing routine endoscopy, no droplets were observed during air insufflation and water suctioning. Droplets were detected in 1 of 11 patients during air suctioning. In 9 of 18 patients undergoing biopsy sampling and 5 of 6 patients undergoing snare polypectomies, droplets were observed at the biopsy channel, mostly when instruments were being removed from the endoscope. CONCLUSIONS: We found that the biopsy channel may be a source of infectious droplets, especially during the removal of instruments from the biopsy channel. When compared with droplets reported from the mouth and anus, these droplets were larger in size and therefore potentially more infectious.

Coronavirus disease-2019: implications for the gastroenterologist.

PURPOSE OF REVIEW: The COVID-19 pandemic has impacted the practicing gastroenterologist in several ways. Although majority of COVID-19 patients present with respiratory symptoms, gastrointestinal symptoms are also seen. COVID-19 has also disrupted gastrointestinal endoscopy services in numerous ways. There are also concerns regarding the impact of these changes on gastrointestinal cancer screening and management of chronic gastrointestinal diseases. The purpose of this review is to provide an overview of the implications of COVID-19 for the practicing gastroenterologist. RECENT FINDINGS: COVID-19 patients can have gastrointestinal symptoms including diarrhea, nausea and vomiting, abdominal pain and anorexia. Separate from the management of COVID-19 patients, there has been a reduction in endoscopy volume worldwide. This has also resulted in reduction/cessation of in-person clinic visits and an increasing use of telemedicine services. In addition, patients with certain chronic diseases like chronic liver disease or inflammatory bowel disease may have worse outcomes during the COVID-19 pandemic. SUMMARY: Gastroenterologists need to rapidly adapt to the challenges being faced and need to make both systems and practice-based changes to the endoscopy unit and outpatient clinic practices. Gastroenterologists should stay up-to-date with the rapidly evolving literature regarding gastrointestinal symptoms in COVID-19 patients as well as its impact on chronic gastrointestinal illnesses.

Triage of General Gastrointestinal Endoscopic Procedures During the COVID-19 Pandemic: Results From a National Delphi Consensus Panel.

BACKGROUND AND AIMS: As the COVID-19 pandemic moves into the postpeak period, the focus has now shifted to resuming endoscopy services to meet the needs of patients who were deferred. By using a modified Delphi process, we sought to develop a structured framework to provide guidance regarding procedure indications and procedure time intervals. METHODS: A national panel of 14 expert gastroenterologists from throughout the US used a modified Delphi process, to achieve consensus regarding: (1) common indications for general endoscopy, (2) critical patient-important outcomes for endoscopy, (3) defining time-sensitive intervals, (4) assigning time-sensitive intervals to procedure indications. Two anonymous rounds of voting were allowed before attempts at consensus were abandoned. RESULTS: Expert panel reached consensus that procedures should be allocated to one of three timing categories: (1) time-sensitive emergent = scheduled within 1 week, (2) time-sensitive urgent = scheduled within 1-8 weeks, (3) nontime sensitive = defer to > 8 weeks and reassess timing then. The panel identified 62 common general endoscopy indications (33 for EGD, 21 for colonoscopy, 5 for sigmoidoscopy). Consensus was reached on patient-important outcomes for each procedure indication, and consensus regarding timing of the procedure indication was achieved for 74% of indications. Panelists also identified adequate personal-protective-equipment, rapid point-of-care testing, and staff training as critical preconditions before endoscopy services could be resumed. CONCLUSION: We used the validated Delphi methodology, while prioritized patient-important outcomes, to provide consensus recommendations regarding triaging a comprehensive list of general endoscopic procedures.

Triaging advanced GI endoscopy procedures during the COVID-19 Pandemic: consensus recommendations using the Delphi method

Background and Aims There remains a lack of consensus on which gastrointestinal endoscopic procedures should be performed during the COVID-19 pandemic, and which procedures could be safely deferred without significantly impacting outcomes. Methods We selected a panel of 14 expert endoscopists. We identified 41 common indications for advanced endoscopic procedures from the ASGE Appropriate Use of GI Endoscopy guidelines. Using a modified Delphi method, we first achieved consensus on patient-important outcome for each procedural indication. Panelists prioritized consensus patient-important outcome when categorizing each indication into one of the following 3 procedural time periods: (1) time-sensitive emergent (schedule within 1 week), (2) time-sensitive urgent (schedule within 1 to 8 weeks), and (3) non-time sensitive (defer for >8 weeks and then reassess the timing). Three anonymous rounds of voting were allowed before attempts at consensus were abandoned. Results All 14 invited experts agreed to participate in the study. The prespecified consensus threshold of 51% was achieved for assigning patient-important outcome/s to each advanced endoscopy indication. The prespecified consensus threshold of 66.7% was achieved for 40 out of 41 advanced endoscopy indications in stratifying them into 1 of 3 procedural time periods. For 12 out of 41 indications 100% consensus, and for 20 out of 41 indications 75% to 99% consensus was achieved. Conclusions By using a Modified Delphi method that prioritized patient-important outcomes, we developed consensus recommendations on procedural timing for common indications for advanced endoscopy. These recommendations and the structured decision framework provided by our study can inform decision-making as endoscopy services are reopened.

What constitutes urgent endoscopy? A social media snapshot of gastroenterologists' views during the COVID-19 pandemic.

Background and study aims There is a consensus among gastroenterology organizations that elective endoscopic procedures should be deferred during the COVID-19 pandemic. While the decision to perform urgent procedures and to defer entirely elective procedures is mostly evident, there is a wide "middle ground" of time-sensitive but not technically urgent or emergent endoscopic interventions. We aimed to survey gastroenterologists worldwide using Twitter to help elucidate these definitions using commonly encountered clinical scenarios during the COVID-19 pandemic. Methods A 16-question survey was designed by the authors to include common clinical scenarios that do not have clear guidelines regarding the timing or urgency of endoscopic evaluation. This survey was posted on Twitter. The survey remained open to polling for 48 hours. During this time, multiple gastroenterologists and fellows with prominent social media presence were tagged to disseminate the survey. Results The initial tweet had 38,795 impressions with a total of 2855 engagements. There was significant variation in responses from gastroenterologists regarding timing of endoscopy in these semi-urgent scenarios. There were only three of 16 scenarios for which more than 70 % of gastroenterologists agreed on procedure-timing . For example, significant variation was noted in regard to timing of upper endoscopy in patients with melena, with 44.5 % of respondents believing that everyone with melena should undergo endoscopic evaluation at this time. Similarly, about 35 % of respondents thought that endoscopic retrograde cholangiopancreatography should only be performed in patients with choledocholithiasis with abdominal pain or jaundice. Conclusion Our analysis shows that there is currently lack of consensus among gastroenterologists in regards to timing of semi-urgent or non-life-threatening procedures during the COVID-19 pandemic. These results support the need for the ongoing development of societal guidance for these "semi-urgent" scenarios to help gastroenterologists in making difficult triage decisions.
