A previously healthy 58-year-old man presented with a septic thrombosis of the right hepatic vein and a pyogenic liver abscess (PLA) one week after undergoing a screening colonoscopy. Blood cultures and a radiological drainage specimen were both positive for Streptococcus anginosus. Evolution was favourable after six weeks of antibiotherapy. To the authors' knowledge, the present report is the first to describe a PLA following a screening colonoscopy with no intervention. The authors hypothesize that silent microperforations during colonoscopy contributed to the infection. Although 20% to 40% of reported PLA cases are cryptogenic in the literature, it may be because of failure to recognize and report a precipitating factor such as colonoscopy. As more cases similar to the present case are reported, the number of cryptogenic cases may decrease.

Chronic active Epstein‒Barr virus colitis, a rare cause of recurrent diarrhea in an immunocompetent female: a case report.
BMC Infect Dis
January 2025
Center of Infectious Disease, West China Hospital, Sichuan University, Chengdu, China.
Background: Chronic active Epstein-Barr virus (CAEBV) colitis is a rare disease with clinical and endoscopic manifestations very similar to those of inflammatory bowel disease (IBD). In clinical practice, it is easy to be misdiagnosed and mistreated, leading to poor clinical outcomes.
Case Presentation: We report a case of a 56-year-old Chinese woman who presented with 6 years of intermittent severe diarrhea, fever, and abdominal pain.
Impact of narrow band imaging in prediction of histology of advanced colorectal neoplasia.
Sci Rep
January 2025
Department of Internal Medicine, 1st Faculty of Medicine Charles University, Military University Hospital, Prague, Czechia.
We assessed the diagnostic performance of the Narrow-Band Imaging (NBI) International Colorectal Endoscopic Classification (NICE) and the Japan NBI Expert Team classification (JNET) in predicting histological outcomes of advanced colorectal lesions. Additionally, we evaluated the sensitivity and positive predictive value (PPV) of the JNET and NICE classifications individually for high-grade lesions (including HGD adenomas, intramucosal carcinomas, and T1 carcinomas). This was a retrospective analysis of prospectively collected data, involving 211 patients (130 men, mean age 60 years) who underwent colonoscopy with endoscopic resection of advanced colorectal neoplasia (lesions ≥ 10 mm).

Background: An increasing body of evidence has linked fructose intake to colorectal cancer (CRC). African American (AA) adults consume greater quantities of fructose and are more likely to develop right-side colon cancer than European American (EA) adults.
Objective: We examined the hypothesis that fructose consumption leads to epigenomic and transcriptomic differences associated with CRC tumor biology.
British Society of Gastroenterology National Evaluation of Colonoscopy Quality: Findings from the National Endoscopy Database.

Population Health Sciences Institute, Newcastle University Centre for Cancer, Newcastle University, Newcastle-upon-Tyne, UK, NE2 4AX; North Tees and Hartlepool NHS Foundation Trust, TS19 8PE.
Background And Aims: Analysis of national colonoscopy quality using automatically uploaded data from a national database, including exploring performance variation.
Methods: Data on all colonoscopies performed in the UK 01/03/2019-29/02/2020 and recorded in the National Endoscopy Database were analysed. Unadjusted key performance indicators were calculated and proportions of endoscopists achieving national standards were determined.
