The US National Library of Medicine and National Institutes of Health manage PubMed.gov which comprises of more than 29 million records, papers, reports for biomedical literature, including MEDLINE, life science and medical journals, articles, reviews, reports and books.
BioPortfolio aims to cross reference relevant information on published papers, clinical trials and news associated with selected topics - speciality.
For example view all recent relevant publications on Epigenetics and associated publications and clincial trials.
Confocal laser endomicroscopy (CLE) has been shown to predict relapse in inflammatory bowel disease (IBD), but its value in the detection of postoperative recurrence in Crohn's disease (CD) is unknown. The aims of this pilot study performed in CD patients after ileocolonic resection were (1) to compare the macroscopic appearance of the neoterminal ileum according to the endoscopic Rutgeerts score with the microscopic findings provided by CLE 6 to 12 months after surgery, and (2) to assess the predictive val...
Polypectomy competency varies significantly among providers. Poor polypectomy technique may lead to interval cancer and/or adverse events. Our aim was to determine the effect of a polypectomy skills report card upon subsequent polypectomy performance.
Few large Western series examine risk factors for recurrence after endoscopic resection (ER) of large (≥20 mm) colorectal laterally spreading tumors. Recurrence beyond initial surveillance is seldom reported and differences between residual/recurrent adenoma and late recurrence are not scrutinised. We report the incidence of recurrence at successive surveillance intervals, identify risk factors for recurrent/residual adenoma and late recurrence, and describe the outcomes of ER of recurrent adenomas.
The incidence of metachronous gastric cancer (MGC) in patients whose primary gastric neoplasm is discovered after Helicobacter pylori (H pylori) eradication remains unclear. Here, we evaluated the long-term effect of previous H pylori eradication on development of MGC after endoscopic submucosal dissection (ESD).
We aimed to develop risk stratification models for advanced colorectal neoplasia (ACRN) and colorectal cancer (CRC) based on fecal hemoglobin (f-Hb) concentration and clinical risk factors.
The aim of this study was to examine clinical outcomes and adverse events (AEs) of self-expandable metal stents (SEMSs) in the management of malignant colonic obstruction (MCO).
Minimum EUS and ERCP volumes that should be offered per trainee in "high quality" advanced endoscopy training programs (AETPs) are not established. We aimed to define the number of procedures required by an "average" advanced endoscopy trainee (AET) to achieve competence in technical and cognitive EUS and ERCP tasks to help structure AETPs.
It is standard of care to perform ileocolonoscopy within a year of ileocolonic resection for Crohn's disease (CD) and to guide management decisions based on the Rutgeert score (RS). The modified RS subdivides i2 into lesions confined to the anastomosis (i2a) or >5 aphthous lesions in the neoterminal ileum (i2b). There is uncertainty, however, if i2a lesions incur an increased risk of disease recurrence. The primary aim of this study was to compare the rates of endoscopic progression between i2a and i2b when...
Colonic endoscopic submucosal dissection (ESD) is more difficult than rectal ESD because of poor maneuverability of the endoscope due to physiological flexion, peristalsis and respiratory movements. The aim of this study is to assess the usefulness of the pocket-creation method (PCM) for colonic ESD compared with the conventional method (CM) regardless of lesion shape or location.
Endoscopic stricturotomy is a novel technique in the treatment of anastomotic strictures in Crohn's disease (CD). The aim of this study was to compare the outcome of patients with ileocolonic anastomotic stricture treated with endoscopic stricturotomy (ESt) versus ileocolonic resection (ICR).
Cold snare polypectomy (CSP) and jumbo forceps polypectomy (JFP) have been shown to be effective for removing diminutive colorectal polyps (DCPs) (≤5 mm). However, no study has compared complete resection rates between CSP and JFP for DCPs. The aim of this study was to compare the efficacy and safety of JFP to CSP for the removal of DCPs.
Self-expanding metal stents (SEMSs) when deployed across the gastroesophageal junction (GEJ) can lead to reflux with risks of aspiration. A SEMS with a tricuspid anti-reflux valve (SEMS-V) was designed to address this issue. The aim of this study was to evaluate the efficacy and safety of this stent.
A fecal immunochemical test (FIT) is often repeated annually, even after a recent colonoscopy. However, there are no published data on the proper approach to FIT-positive patients after a recent colonoscopy. We compared colorectal cancer (CRC) and advanced colorectal neoplasia (ACRN) prevalence based on the interval since the last colonoscopy.
Colonoscopy insertion is painful for some patients, constituting one of the main barriers to screening colonoscopy. Few studies have assessed the impact of the supine position (SP) on colonoscopy insertion, especially for unsedated patients. The aim of this randomized controlled trial (RCT) is to clarify this issue.
