Bowel preparation for small bowel capsule endoscopy: standard regimen with 2 L polyethylene glycol versus 1 L polyethylene glycol plus ascorbate.

Background/aims: Optimization of bowel preparation for small bowel capsule endoscopy (SBCE) is debated. Guidelines recommend 2 L of iso-osmolar polyethylene glycol (PEG) to improve SBCE visibility. We compared the efficacy of the standard 2 L PEG solution with a 1 L PEG plus ascorbate (PEG-ASC) preparation, which has already been established for large-bowel preparation.

Effect of antithrombotic therapies on small bowel bleeding: an European multicenter retrospective study.

Background/aims: Small bowel bleeding (SBB) is the main indication for videocapsule endoscopy (VCE); the diagnostic yield (DY) could be influenced by antithrombotic therapies. We explored the effects of these therapies on SBB.

Methods: Consecutive patients from two centers (Milan, Italy and Sheffield, UK) who underwent VCE between March 2001 and July 2020 were considered.

Mannitol for bowel preparation: Efficacy and safety results from the SATISFACTION randomised clinical trial.

Background: Bowel preparation represents a significant issue to high-quality colonoscopy. Oral mannitol requires a single dose, is of low volume, and has a pleasant taste and rapid action.

Aims: This SATISFACTION study compared single-dose (same day) oral mannitol 100 g/750 mL with standard split-dose PEG-ASC2 L (MoviPrep®).

Clinical features and risk factors for colorectal gas explosion during digestive endoscopy and surgery: a systematic review.

Background And Aims: Colorectal gas explosion (CGE) is an exceptional but potentially fatal complication of digestive endoscopy or surgery. The role played by bowel preparations and endoscopic or surgical devices in the risk of CGE is still unclear. We conducted a systematic review of the literature to identify risk factors for CGE.

Advanced Endoscopic Imaging for Assessing Mucosal Healing and Histologic Remission in Inflammatory Bowel Diseases.

Recent advances in the field of endoscopy have found fertile ground for application in inflammatory bowel diseases (IBD). Mucosal healing is a primary goal of IBD therapy, and current evidence shows that histologic remission (HR) is an additional desirable outcome. However, with the use of standard endoscopy, a considerable number of patients with histologically active disease go unrecognized.

Computer aided villi morphometric quantification in video-capsule enteroscopy: A newly developed software to quantify small bowel atrophy.

Background And Aims: Small bowel capsule endoscopy (SBCE) has an established role in patients with non-responsive celiac disease (CeD). A non-invasive method to quantify small bowel atrophy is still lacking.

Methods: We analysed SBCE frames from CeD patients from 2018 to 2020.

Incomplete small bowel capsule endoscopy: Risk factors and cost-effectiveness of real-time viewing.

International guidelines recommend real-time viewing (RTV) in capsule endoscopy for gastric emptying monitoring, yet it is often overlooked in clinical practice. We aimed to assess risk factors for incomplete small bowel capsule endoscopy (SBCE) and evaluate the clinical relevance and cost-effectiveness of RTV implementation. We included consecutive SBCEs from 2013 to 2020.

Pan-enteric Capsule Endoscopy to Characterize Crohn's Disease Phenotypes and Predict Clinical Outcomes in Children and Adults: The Bomiro Study.

Background: Pan-enteric capsule endoscopy (PCE) provides useful information for the management of Crohn's disease (CD), especially in children. No study has evaluated the ability of PCE to characterize CD phenotypes and outcomes in children and adults.

Methods: In a prospective multicenter observational study, we recruited patients with CD >6 years from 4 centers in Italy.

Can artificial intelligence replace endoscopists when assessing mucosal healing in ulcerative colitis? A systematic review and diagnostic test accuracy meta-analysis.

Backgrounds And Aims: Mucosal healing (MH) in inflammatory bowel diseases (IBD) is an important landmark for clinical decision making. Artificial intelligence systems (AI) that automatically deliver the grade of endoscopic inflammation may solve moderate interobserver agreement and the need of central reading in clinical trials.

Methods: We performed a systematic review of EMBASE and MEDLINE databases up to 01/12/2022 following PRISMA and the Joanna Briggs Institute methodologies to answer the following question: "Can AI replace endoscopists when assessing MH in IBD?".

Validation of a new optical diagnosis training module to improve dysplasia characterization in inflammatory bowel disease: a multicenter international study.

Background And Aims: Inflammatory bowel disease (IBD) increases risk of dysplasia and colorectal cancer. Advanced endoscopic techniques allow for the detection and characterization of IBD dysplastic lesions, but specialized training is not widely available. We aimed to develop and validate an online training platform to improve the detection and characterization of colonic lesions in IBD: OPtical diagnosis Training to Improve dysplasia Characterization in Inflammatory Bowel Disease (OPTIC-IBD).

The carbon cost of inappropriate endoscopy.

Background And Aims: Digestive endoscopy is a resource-intensive activity with a conspicuous carbon footprint and an estimated rate of inappropriateness. However, the carbon costs of inappropriate endoscopic procedures still remain obscure. Here we evaluated the environmental impact of inappropriate endoscopic examinations.

Clinical impact of videocapsule endoscopy and device-assisted enteroscopy in non-bleeding small bowel lesions.

Background: Videocapsule endoscopy (VCE) and double-balloon enteroscopy (DBE) are part of the diagnostic and therapeutic work-up of indications other than suspected small bowel bleeding (OSBB). The literature is currently lacking studies describing these procedures in this particular setting.

Objectives: We assessed the clinical impact of VCE and DBE in a large monocentric cohort of OSBB patients, as compared to a control group of suspected small bowel bleeding (SSBB) patients who underwent enteroscopy over the same period.

Personalize, participate, predict, and prevent: 4Ps in inflammatory bowel disease.

Inflammatory bowel disease (IBD), which includes Crohn's disease (CD) and ulcerative colitis (UC), is a complex, immune-mediated, disorder which leads to several gastrointestinal and systemic manifestations determining a poor quality of life, disability, and other negative health outcomes. Our knowledge of this condition has greatly improved over the last few decades, and a comprehensive management should take into account both biological (i.e.

Pharmacokinetics of oral mannitol for bowel preparation for colonoscopy.

This study aimed to define the pharmacokinetics (PKs) of oral mannitol used as an osmotic laxative for bowel preparation for colonoscopy. The PKs of oral mannitol was evaluated in a substudy as part of a phase II dose-finding, international, multicenter, randomized, parallel-group, endoscopist-blinded study. Patients were randomly assigned to take 50, 100, or 150 g mannitol.

Artificial Intelligence Enabled Histological Prediction of Remission or Activity and Clinical Outcomes in Ulcerative Colitis.

Background & Aims: Microscopic inflammation has significant prognostic value in ulcerative colitis (UC); however, its assessment is complex with high interobserver variability. We aimed to develop and validate an artificial intelligence (AI) computer-aided diagnosis system to evaluate UC biopsies and predict prognosis.

Methods: A total of 535 digitalized biopsies (273 patients) were graded according to the PICaSSO Histologic Remission Index (PHRI), Robarts, and Nancy Histological Index.

Factors influencing the presence of potentially explosive gases during colonoscopy: Results of the SATISFACTION study.

This study tested the hypothesis that bowel preparation with mannitol should not affect the colonic concentration of H and CH . Therefore, the SATISFACTION study, an international, multicenter, randomized, parallel-group phase II-III study investigated this issue. The phase II dose-finding part of the study evaluated H , CH , and O concentrations in 179 patients randomized to treatment with 50 g, 100 g, or 150 g mannitol.
