Background: Early identification of pediatric inflammatory bowel disease (IBD) improves long-term outcomes; yet, significant diagnostic delays persist. This study aimed to establish and validate the optimal model of noninvasive evaluation tests to help clinicians with the early identification of pediatric IBD.

Methods: The study adopted a retrospective development and prospective temporal validation design within the same clinical center.

Background: A congenital duodenal diaphragm (CDD) is a rare cause of duodenal obstruction in infants and children. The traditional approach to treatment has been surgical intervention either with excision and duodenoplasty or with bypass through a duodenoduodenostomy, which is invasive and carries the risk of anastomotic leakage.

Aims: To summarize the key points of differential diagnosis and treatment of a CDD under gastroscopy and to evaluate its efficacy and safety.

Background: Very early-onset inflammatory bowel disease (VEOIBD) with interleukin-10 (IL10R) signaling deficiency usually requires enterostomy in patients who are refractory to traditional treatment. This study aimed to evaluate long-term outcomes after enterostomy for VEOIBD patients with IL10R signaling deficiency.

Methods: The medical records of all patients undergoing enterostomy for signaling deficiency were retrospectively assessed during 2012.

Background And Aims: Objective evaluation of treatment response is critical in the management of Crohn's disease (CD). Compared with endoscopy, intestinal ultrasound (IUS) is non-invasive and well-tolerated. This study is aimed to assess the predictive value of IUS score for treatment response in pediatric CD patients.

Background: Infantile-onset inflammatory bowel disease can be caused by defects in interleukin-10 signalling. The natural history and clinical outcomes of allogeneic haematopoietic stem cell transplantation, medical treatment and surgery have not been thoroughly described.

Aims: This study evaluates disease progression and clinical outcome in patients with interleukin-10 signalling deficiency.

Infliximab is an effective therapy for Crohn's disease (CD). Early non-invasive predictors of disease remission allow for modification of treatments. The aim of this study was to investigate the associations between genetic variants, pharmacokinetics, and infliximab efficacy in pediatric patients with CD.

Background: Defects in interleukin 10 (IL10) and its receptors are particularly involved in very early onset inflammatory bowel disease (VEOIBD). However, large fragment deletions of IL10 receptor A (IL10RA) are rare.

Methods: VEOIBD patients with confirmed mutations in the IL10RA gene were enrolled from January 1, 2019 to June 30, 2020.

Background: intestinal lymphangiectasia is an unusual cause of protein-losing enteropathy due to either congenital malformation or obstruction of the intestinal lymphatics. However, few reports have investigated the use of video capsule endoscopy in children with intestinal lymphangiectasia. This study was performed to evaluate the diagnostic value of video capsule endoscopy for pediatric intestinal lymphangiectasia.

Video capsule endoscopy (VCE) can detect mucosal lesions in the intestine, especially in the small bowel.Our study aims to evaluate the applications of VCE for pediatric gastrointestinal diseases.In this retrospective study, we included all patients who underwent VCE between December 2012 and December 2018.

Objective: To evaluate the value of capsule endoscopy in children with small intestinal diseases with hematochezia as the chief complaint.

Methods: A retrospective analysis was performed on the clinical data and capsule endoscopy findings of 93 children with hematochezia who were admitted to Children's Hospital of Fudan University from May 2015 to January 2019 and underwent capsule endoscopy. According to the capsule endoscopy findings of the jejunum and the ileum, they were divided into a positive lesion group with 39 patients and a negative lesion group with 54 patients.

Background: The aim of this study was to prospectively study the effect of exclusive enteral nutrition (EEN) treatment on Chinese pediatric Crohn's disease (CD) patients.

Methods: Thirty-one newly diagnosed CD patients were enrolled in this study and treated with EEN for 8 weeks. Twelve healthy controls (HCs) donated their fecal samples.

Background: Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract and is also an important cause of bloody stool and anemia in children. However, there are few data about video capsule endoscopy (VCE) for MD in children. This study aimed to evaluate the diagnostic value of VCE for MD in children.

Backgrounds: Due to the decreasing eradication rate of Helicobacter pylori, some novel alternatives have been developed, such as bismuth-containing quadruple therapy and non-bismuth-containing quadruple therapy (sequential and concomitant treatment). Little is known about whether a success rate above 90% can be achieved with these regimens in Chinese children.

Methods: In this prospective, open, comparative cross-sectional study, we recruited treatment-naïve children (aged between 6 and 18 years) with H pylori infection.

Background: Interleukin-10 (IL10) signalling pathway deficiency results in severe very early onset inflammatory bowel disease (VEOIBD), and enterostomy is often inevitable. However, studies in these surgical populations are lacking. This study aims to determine the enterostomy characteristics, postoperative complications and related risk factors in enterostomy patients.

Aim: To determine whether cell division cycle (Cdc)42 is regulated by microRNA (miR)-15a in the development of pediatric inflammatory bowel disease (IBD).

Methods: We cultured 293T cells, used plasmids and performed dual-luciferase assay to determine whether Cdc42 is a miR-15a target gene. We cultured Caco-2 cells, and stimulated them with tumor necrosis factor (TNF)-α.

Background: Interleukin-10 (IL10)/interleukin-10 receptor (IL10R) deficiency is a rare disease with life-threatening infantile-onset colitis. We sought to accurately phenotype this disorder based on a large cohort of patients with a proven defect of IL10 signaling and to clarify the effects of allogeneic hematopoietic stem cell transplantation (HSCT).

Methods: We analyzed the phenotypes of our 61 patients and reviewed 78 other previously reported cases with identified mutations in the genes encoding IL10 or IL10R.

Background: Mutations in tumor necrosis factor alpha-induced protein 3 (TNFAIP3), a key player in the negative feedback regulation of nuclear factor-κB signaling, have recently been recognized as leading to early onset autoinflammatory and autoimmune syndrome. Here, we have reported the phenotypes of 3 infantile onset intractable inflammatory bowel disease (IBD) patients with TNFAIP3 mutations and reviewed previously reported cases to establish phenotypic features associated with TNFAIP3 monogenicity.

Methods: From January 1, 2015, to December 31, 2017, we recruited 58 infantile-onset IBD patients.
