Objective: Duodenoscopy-associated infections and outbreaks are reported globally despite strict adherence to duodenoscope reprocessing protocols. Therefore, new developments in the reprocessing procedure are needed.

Design: We evaluated a novel dynamic flow model for an additional cleaning step between precleaning and manual cleaning in the reprocessing procedure.

Acute diarrhoea can be caused by species, species, , species and (SSYCP). In clinical practice, however, polymerase chain reaction (PCR) for SSYCP is frequently performed as part of the diagnostic work-up for patients with chronic diarrhoea and gastrointestinal complaints. This study postulates that PCR for SSYCP is of limited clinical use in patients with chronic diarrhoea and gastrointestinal complaints.

Duodenoscopy-associated infections occur worldwide despite strict adherence to reprocessing standards. The exact scope of the problem remains unknown because a standardized sampling protocol and uniform sampling techniques are lacking. The currently available multi-society protocol for microbial culturing by the Centers for Disease Control and Prevention, the United States Food and Drug Administration (FDA) and the American Society for Microbiology, published in 2018 is too laborious for broad clinical implementation.

Radiologically inserted gastrostomy (RIG) is an alternative to percutaneous endoscopic gastrostomy (PEG) for patients with eating difficulties who need long-term enteral nutrition. This articles provides an overview of the technique of RIG as well as an analysis of the results of RIG at our institute over the last five years and a discussion of the literature. The number of centres in the Netherlands offering RIG is growing and therefore we want to raise awareness amongst colleagues who are not familiar with this alternative to PEG.

In this case, we present an uncommon gastrointestinal infection in an immunocompromised patient that was solely diagnosed because of close collaboration between treating physicians and microbiologists. The patient is a 42-year-old male who underwent heart transplantation 5 years earlier. He presented with fever, weight loss, diarrhoea and tiredness.

Background And Aims: Worldwide, an increasing number of duodenoscope-associated outbreaks are reported. The high prevalence rate of contaminated duodenoscopes puts patients undergoing ERCP at risk of exogenous transmission of microorganisms. The contributing factors of the duodenoscope design to contamination are not well understood.

Dientamoeba fragilis (D. fragilis) is an intestinal parasite frequently detected in humans with abdominal pain and diarrhoea, but it is also commonly found in asymptomatic subjects. Hence its clinical relevance is often disputed.

Background And Aims: Electromagnetic-guided placement (EMP) of a nasoduodenal feeding tube by trained nurses is an attractive alternative to EGD-guided placement (EGDP). We aimed to compare EMP and EGDP in outpatients, ward patients, and critically ill patients with normal upper GI anatomy.

Methods: In 3 centers with no prior experience in EMP, patients were randomized to placement of a single-lumen nasoduodenal feeding tube either with EGDP or EMP.

Objectives: Electromagnetic (EM)-guided bedside placement of nasoenteral feeding tubes by nurses may improve efficiency and reduce patient discomfort and costs compared with endoscopic placement by gastroenterologists. However, evidence supporting this task shift from gastroenterologists to nurses is limited. We aimed to compare the effectiveness of EM-guided and endoscopic nasoenteral feeding tube placement.

The implementation of polymerase chain reaction (PCR)-based diagnostics of intestinal protozoa has led to higher sensitivity and (subtype) specificity, more convenient sampling, and the possibility for high-throughput screening. PCR for routine detection of human intestinal protozoa in fecal samples is used by an increasing number of clinical laboratories. This paper discusses the recent developments in the diagnosis of intestinal protozoa, with an emphasis on PCR-based diagnostics.

Background: Gastroparesis is common in surgical patients and frequently leads to the need for enteral tube feeding. Nasoenteral feeding tubes are usually placed endoscopically by gastroenterologists, but this procedure is relatively cumbersome for patients and labor-intensive for hospital staff. Electromagnetic (EM) guided bedside placement of nasoenteral feeding tubes by nurses may reduce patient discomfort, workload and costs, but randomized studies are lacking, especially in surgical patients.

Background: Adequate bowel preparation is important for optimal colonoscopy. It is important to identify patients at risk for inadequate bowel preparation because this allows taking precautions in this specific group.

Objective: To develop a prediction score to identify patients at risk for inadequate bowel preparation who may benefit from an intensified bowel cleansing regimen.

Objectives: To determine whether endoscopic clip-assisted nasoenteral feeding tube placement is more effective than standard feeding tube placement with transnasal endoscopy.

Methods: Between August 2009 and February 2011, 143 patients referred for endoscopic nasoenteral feeding tube placement were randomized between clip-assisted and standard nasoenteral tube placement. Endoscopies were performed in the endoscopy unit and intensive care unit in a tertiary referral center in the Netherlands.

Article Synopsis
  • A 44-year-old male exhibited melena and unstable blood pressure, prompting medical investigation.
  • Initial endoscopic exams of both the upper and lower gastrointestinal tracts did not show any issues.
  • A follow-up gastroduodenoscopy revealed a submucosal mass thought to be an ectopic pancreas, later identified as a gastrointestinal stromal tumor.

Background: In patients with proton pump inhibitor (PPI)-resistant symptoms, ambulatory 24-h pH-impedance monitoring can be used to assess whether a relationship exists between symptoms and reflux episodes. Until now, it is unclear whether combined pH-impedance monitoring in these patients should be performed on or off PPI.

Methods: Thirty patients with symptoms of heartburn, chest pain, and/or regurgitation despite PPI twice daily underwent ambulatory 24-h pH-impedance monitoring twice, once on PPI and once after cessation of the PPI for 7 days.

Background: Beneficial effects of probiotics have been reported in liver disease. Inflammatory bowel disease concurs in 90% of primary sclerosing cholangitis (PSC) patients, suggesting that substances originating from the inflamed gut may damage the biliary tree.

Objective: To assess potential beneficial effects of probiotics on serum liver tests, pruritus and fatigue in PSC.
