Challenges of developing and executing a multi-site registry for a novel device with evolving indications for use.

BACKGROUND: The introduction of new technologies in endoscopy has been met with uncertainty, skepticism, and lack of standardization or training parameters, particularly when disruptive devices or techniques are involved. The widespread availability of a novel endoscopic suturing device (OverStitch™) for tissue apposition has enabled the development of applications of endoscopic suturing. METHODS: The American Gastroenterological Association partnered with Apollo Endosurgery to develop a registry to capture in a pragmatic non-randomized study the safety, effectiveness, and durability of endoscopic suturing in approximating tissue in the setting of bariatric revision and fixation of endoprosthetic devices. RESULTS: We highlight the challenges of the adoption of novel techniques by examining the process of developing and executing this multicenter registry to assess real-world use of this endoscopic suturing device. We also present our preliminary data on the safety and effectiveness of the novel device as it is applied in the treatment of obesity. CONCLUSIONS: The Prospective Registry for Trans-Orifice Endoscopic Suturing Applications (ES Registry) was an effective Phase 4, postmarketing registry aimed at capturing pragmatic, real-world use of a novel device. These findings serve to solidify the role of endoscopic suturing in clinical practice.

Analysis of Outcomes in COVID-19 Patients With Varying Degrees of Hyperlipasemia.

OBJECTIVES: Coronavirus disease 2019 (COVID-19) patients may have varying degrees of hyperlipasemia. The aim was to compare outcomes among different levels of hyperlipasemia in patients with COVID-19. METHODS: This is a retrospective study examining outcomes among hospitalized COVID-19 patients with a lipase <3× upper limit of normal (ULN), asymptomatic hyperlipasemia (>3× ULN), secondary pancreatitis (typical respiratory COVID-19 symptoms and found to have pancreatitis), and primary pancreatitis (presenting with pancreatitis). RESULTS: Of 11,883 patients admitted with COVID-19, 1560 patients were included: 1155 patients had normal serum lipase (control group), 270 had elevated lipase <3× ULN, 46 patients had asymptomatic hyperlipasemia with lipase >3× ULN, 57 patients had secondary pancreatitis, and 32 patients had primary pancreatitis. On adjusted multivariate analysis, the elevated lipase <3× ULN and asymptomatic hyperlipasemia groups had worse outcomes with higher mortality (odds ratio [OR], 1.6 [95% confidence interval [CI], 1.2-2.2) and 1.1 [95% CI, 0.5-2.3], respectively), higher need for mechanical ventilation (OR, 2.8 [95% CI, 1.2-2.1] and 2.8 [95% CI, 1.5-5.2], respectively), and longer length of stay (OR, 1.5 [95% CI, 1.1-2.0] and 3.16 [95% CI, 1.5-6.5], respectively). CONCLUSIONS: Patients with COVID-19 with elevated lipase <3× ULN and asymptomatic hyperlipasemia have generally worse outcomes than those with pancreatitis.

Prospective analysis of SARS-CoV-2 dissemination to environmental surfaces during endoscopic procedures.

Background and study aims The COVID-19 pandemic has disrupted routine medical care due to uncertainty regarding the risk of viral spread. One major concern for viral transmission to both patients and providers is performing aerosol-generating procedures such as endoscopy. As such, we performed a prospective study to examine the extent of viral contamination present in the local environment before and after endoscopic procedures on COVID-19 positive patients. Materials and methods A total of 82 samples were collected from 23 surfaces in the procedure area of four COVID-positive patients undergoing upper endoscopic procedures. Samples were collected both before and after the procedure. severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA was extracted and quantified using reverse transcription quantitative polymerase chain reaction with primers to detect nucleocapsid RNA, and results reported as the number of viral copies per square centimeter of contaminated surface. Results A total of six positive samples were detected from three of the four patients. The floor beneath the patient bed was the most common site of viral RNA, but RNA was also detected on the ventilator monitor prior to the procedure and the endoscope after the procedure. Conclusions The risk of SARS-CoV-2 transmission associated with upper endoscopy procedures is low based on the low rate of surface contamination. Some surfaces in close proximity to the patient and endoscopist may pose a higher risk for contamination. Patient positioning and oxygen delivery methods may influence the directionality and extent of viral spread. Our results support the use of appropriate personal protection to minimize risk of viral transmission.

Gastrointestinal endoscopy during the coronavirus pandemic in the New York area: results from a multi-institutional survey.

Background and study aims The coronavirus disease 2019 (COVID-19), and measures taken to mitigate its impact, have profoundly affected the clinical care of gastroenterology patients and the work of endoscopy units. We aimed to describe the clinical care delivered by gastroenterologists and the type of procedures performed during the early to peak period of the pandemic. Methods Endoscopy leaders in the New York region were invited to participate in an electronic survey describing operations and clinical service. Surveys were distributed on April 7, 2020 and responses were collected over the following week. A follow-up survey was distributed on April 20, 2020. Participants were asked to report procedure volumes and patient characteristics, as well protocols for staffing and testing for COVID-19. Results Eleven large academic endoscopy units in the New York City region responded to the survey, representing every major hospital system. COVID patients occupied an average of 54.5 % (18 - 84 %) of hospital beds at the time of survey completion, with 14.5 % (2 %-23 %) of COVID patients requiring intensive care. Endoscopy procedure volume and the number of physicians performing procedures declined by 90 % (66 %-98 %) and 84.5 % (50 %-97 %) respectively following introduction of restricted practice. During this period the most common procedures were EGDs (7.9/unit/week; 88 % for bleeding; the remainder for foreign body and feeding tube placement); ERCPs (5/unit/week; for cholangitis in 67 % and obstructive jaundice in 20 %); Colonoscopies (4/unit/week for bleeding in 77 % or colitis in 23 %) and least common were EUS (3/unit/week for tumor biopsies). Of the sites, 44 % performed pre-procedure COVID testing and the proportion of COVID-positive patients undergoing procedures was 4.6 % in the first 2 weeks and up to 19.6 % in the subsequent 2 weeks. The majority of COVID-positive patients undergoing procedures underwent EGD (30.6 % COVID +) and ERCP (10.2 % COVID +). Conclusions COVID-19 has profoundly impacted the operation of endoscopy units in the New York region. Our data show the impact of a restricted emergency practice on endoscopy volumes and the proportion of expected COVID positive cases during the peak time of the pandemic.
