Covid-19 pandemic impact on colonoscopy service and suggestions for managing recovery
Abstract Background and aim As the post-peak phase of the epidemic is approaching, there is an urgent need of an action plan to help resume endoscopy activity. To manage the Covid-19 pandemic-imposed backlog of postponed colonoscopy examinations, an efficient approach is needed. The practice of on-demand sedation with benzodiazepines and/or opiates will allow most patients to complete a water-aided examination with minimal or no sedation. Other methods reported to minimize patient discomfort during colonoscopy can be used, in addition to water-aided techniques. Unsedated or minimally sedated patients who do not require recovery or require a shorter one allow rapid turnaround. The practice obviates the need for assistance with deep sedation from anesthesiologists, who may be in short supply. Trainee education in water-aided colonoscopy has been demonstrated to confer benefits. This review provides some insights into the impact of Covid-19 on endoscopy services, challenges ahead, and possible solutions to help recovery of colonoscopy work and training
Safety of Thioguanine in Pediatric Inflammatory Bowel Disease:A Multi-Center Case Series
Thioguanine (TG) has been shown as a safe alternative in adults with inflammatory bowel disease (IBD) who did not tolerate conventional thiopurines [azathioprine (AZA)/mercaptopurine]. However, data in pediatric IBD are scarce. Therefore, we aimed to assess the safety of TG as maintenance therapy. METHODS: A retrospective, multicenter cohort study of children with IBD on TG was performed in the Netherlands. TG-related adverse events (AE) were assessed and listed according to the common terminology criteria for AE. RESULTS: Thirty-six children with IBD (median age 14.5 years) on TG (median dose 15 mg/day) were included in 6 centers. Five AE occurred during follow-up [pancreatitis (grade 3), hepatotoxicity (grade 3) (n = 2), Clostridium difficile infection (grade 2), and abdominal pain (grade 2)]. All patients (n = 8) with a previously AZA-induced pancreatitis did not redevelop pancreatitis on TG. CONCLUSIONS: In pediatric IBD, TG seems a safe alternative in case of AZA-induced pancreatitis. Further research assessing long-term TG-related safety and efficacy is needed
Fluid hydration to prevent post-ERCP pancreatitis in average- to high-risk patients receiving prophylactic rectal NSAIDs (FLUYT trial): Study protocol for a randomized controlled trial
Background: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most common complication of ERCP and may run a severe course. Evidence suggests that vigorous periprocedural hydration can prevent PEP, but studies to date have significant methodological drawbacks. Importantly, evidence for its added value in patients already receiving prophylactic rectal non-steroidal anti-inflammatory drugs (NSAIDs) is lacking and the cost-effectiveness of the approach has not been investigated. We hypothesize that combination therapy of rectal NSAIDs and periprocedural hydration would significantly lower the incidence of post-ERCP pancreatitis compared to rectal NSAIDs alone in moderate- to high-risk patients undergoing ERCP. Methods: The FLUYT trial is a multicenter, parallel group, open label, superiority randomized controlled trial. A total of 826 moderate- to high-risk patients undergoing ERCP that receive prophylactic rectal NSAIDs will be randomized to a control group (no fluids or normal saline with a maximum of 1.5 mL/kg/h and 3 L/24 h) or intervention group (lactated Ringer's solution with 20 mL/kg over 60 min at start of ERCP, followed by 3 mL/kg/h for 8 h thereafter). The primary endpoint is the incidence of post-ERCP pancreatitis. Secondary endpoints include PEP severity, hydration-related complications, and cost-effectiveness. Discussion: The FLUYT trial design, including hydration schedule, fluid type, and sample size, maximize its power of identifying a potential difference in post-ERCP pancreatitis incidence in patients receiving prophylactic rectal NSAIDs
Human transmission of blastocystis by fecal microbiota transplantation without development of gastrointestinal symptoms in recipients
Background. Patients with multiple recurrent Clostridioides difficile infections (rCDI) are treated with fecal microbiota transplantation (FMT), using feces provided by healthy donors. Blastocystis colonization of donors is considered an exclusion criterion, whereas its pathogenicity is still under debate. Methods. The introduction of molecular screening for Blastocystis sp. at our stool bank identified 2 donors with prior negative microscopies but positive polymerase chain reactions (PCRs). Potential transmission of Blastocystis sp. to patients was assessed on 16 fecal patient samples, pre- and post-FMT, by PCR and subtype (ST) analyses. In addition, clinical outcomes for the treatment of rCDI (n = 31), as well as the development of gastrointestinal symptoms, were assessed. Results. There was 1 donor who carried Blastocystis ST1, and the other contained ST3. All patients tested negative for Blastocystis prior to FMT. With a median diagnosis at 20.5 days after FMT, 8 of 16 (50%) patients developed intestinal colonization with Blastocystis, with identical ST sequences as their respective donors. Blastocystis-containing fecal suspensions were used to treat 31 rCDI patients, with an FMT success rate of 84%. This success rate was not statistically different from patients transferred with Blastocystis sp.–negative donor feces (93%, 76/82). Patients transferred with Blastocystis sp.–positive donor feces did not report any significant differences in bowel complaints in the first week, after 3 weeks, or

Intubation failure during gastroscopy: Incidence, predictors and follow-up findings
Background: Intubation failure (IF) occurs when an endoscopist is unable to progress via the oropharynx into the upper oesophagus. Aim: To assess incidence and aetiology of IF and predictors of structural pharyngeal abnormalities in patients with IF. Methods: All gastroscopies (n=26,130) performed in our centre, between August 2010 and August 2016 were retrospectively reviewed. Barium radiology and repeat gastroscopy findings were evaluated for structural causes of IF. Patients were categorised into ‘failure to tolerate’ and ‘failure to progress’ based on endoscopy reports. Results: The incidence of IF was 0.95%. Rates of IF varied with endoscopist specialty (p=0.021), but not with patient age, sex or sedation dose. Among cases of IF, structural pharyngeal abnormalities were detected on barium radiology in 28.9%, consisting of cricopharyngeal hypertrophy and/or Zenker’s diverticulum in 73.2%. ‘Failure to progress’ predicted pharyngeal pathology in 55.6%. Predictors of structural causes on barium radiology following IF included: age ≥65 (OR 4.0, 95% CI: 1.8-8.9, p<0.001); indication of dysphagia (OR 5.5, 95% CI: 2.5-11.8, p<0.001), and failure of endoscopic progression (OR 5.2, 95% CI: 2.3-12.0, p<0.001). Conclusion: Patients with IF should be investigated owing to the high risk of underlying pathology, particularly if associated with age ≥65, dysphagia, and failure of endoscopic progression. We propose that IF rates of <1% could be used as a quality indicator in gastroscopy
Microscopic colitis
Microscopic colitis (MC) is viewed as an umbrella term applicable to both lymphocytic and collagenous colitis. The first case was published in 1976, a new entity of chronic watery diarrhea with lymphocytic colitis, with or without a subepithelial collagen deposition. Patients are usually middle-aged women, and the pathogenesis is unknown. The response to steroids and the female predominance underlines an autoimmune disease. Up to 40% NSAID and lanzoprazole-induced MC are well-known. Biopsies during sigmoidoscopy in unexplained diarrhea must be standard. Treatment is empirical. The most important step is to ban all NSAIDs and other MC inducing agents. Immunosuppressive treatment must be considered. However, the disease has a benign course and sometimes is selflimiting
