Background & Aims: Intestinal failure (IF) in neonatal and pediatric patients is associated with substantial morbidity. Management of IF includes the formation of a double enterostomy (DES) of the small bowel. Parenteral nutrition (PN) is frequently required, which is expensive. Recycling chyme from the proximal DES limb distally is an alternative therapy, but standardized data on this intervention is lacking. This review systematically evaluated the existing literature on chyme recycling (CR) in neonatal and pediatric populations.
Methods: Medical databases were systematically searched for articles reporting CR in neonatal and pediatric populations. Articles documenting CR indications, methods, clinical outcomes, benefits and adverse events (AEs) were reviewed. A narrative synthesis was performed on the extracted data.
Results: This review identified 20 full-text articles, in which 289 patients received CR, most commonly following necrotizing enterocolitis (n = 117 patients). The most common motivators for CR were proximally located DES (n = 7 articles) and to support nutrition and growth (n = 7 articles). Proximal DES output collection was predominantly manual (n = 11 articles), whereas distal CR was mostly automated (n = 12 articles), using customized peristaltic or syringe infusion pumps. Clinical benefits encompassed PN reduction (n = 19 patients) or cessation (n = 122 patients), weight gain, normalization of fluid balance, improvement in liver function tests and distal gut maturation. Technical problems commonly included tube dislodgement, leakage and effluent reflux (n = 9 articles). AEs included intestinal perforation (n = 3 patients) and haemorrhage (n = 1 patient).
Conclusions: From the limited available data, CR is demonstrated as an effective therapeutic intervention for small bowel DES in pediatric and neonatal patients. However, standardized methods that improve the delivery of and minimise AEs associated with the intervention are needed.

Documented worldwide, impaired immunity is a cardinal signature resulting from loss of dietary zinc, an essential micronutrient. A steady supply of zinc to meet cellular requirements is regulated by an array of zinc transporters. Deletion of the transporter Zip14 (Slc39a14) in mice produced intestinal inflammation.

Background: Videocapsule endoscopy (VCE) is a valuable tool for investigating gastrointestinal (GI) diseases in dogs. Its use is not recommended in dogs ≤4.3 kg, because of risks of GI endoscopic capsule (EC) retention and bowel obstruction.

We describe a case of familial Mediterranean fever (FMF) with sigmoid colon stricture. The patient, a woman in her 30 s, had a 12-year history of ileocolitis-type Crohn's disease. The colonoscope could not pass because of the sigmoid colon stricture, and the patient was referred to our hospital with complaints of abdominal pain and fever.

Background: Ration composition may significantly impact the nutrient absorption, duodenal parameters, intestinal health and feed efficiency of animals.
Objectives: The objective of this study was to analyse the impact of concentrate- and forage-based diets on essential morphological parameters of the duodenum, including villus height, villus width, crypt depth and goblet cell density, in three different lamb breeds.
Methods: Forty-five lambs, aged between 2.

Inflammatory bowel disease (IBD) with the two predominant endophenotypes-Crohn's disease (CD) and ulcerative colitis (UC)-represents a group of chronic gastrointestinal inflammatory conditions. Since most genetic associations with IBD are often limited to independent subtypes, we reported a genome-wide association study (GWAS) cross-trait analysis combined with CD and UC to enhance statistical power. Initially, we detected 256 association signals at 54 genomic susceptibility loci and further characterized the functionality of variants within these regions.
