Background: The Rome IV criteria offer symptom-based recommendations for diagnosing functional gastrointestinal diseases (FGID) in children and adolescents without esophagogastroduodenoscopy (EGD). The aim of this study is to evaluate the usefulness of Rome IV criteria for ruling out organic disease in patients with and without alarm symptoms.

Methods: Retrospective research was conducted on children and adolescents who had dyspepsia and underwent EGD.

Early diagnosis of biliary atresia (BA) and the timing of Kasai hepatic portoenterostomy are associated with improved survival rates of the native liver. Acholic stool is a major and earliest sign of BA. We evaluated the awareness and recognition of medical students and primary health care professionals (PHCPs) about neonatal cholestasis and acholic stool as a marker of BA.

Objective: To determine the accuracy of 2D shear-wave elastography (2D-SWE) in pediatric age group patients in differentiating clinically insignificant and significant liver fibrosis using METAVIR fibrosis scoring system as the gold standard.

Introduction: Liver biopsy has long been the gold standard in liver fibrosis diagnosis. However, due to probable complications and sampling variabilities, the need for more accurate and non-invasive techniques has increased.

Portal hypertensive biliopathy may occur in patients with noncirrhotic hepatic fibrosis. Portal hypertensive biliopathy treatment should be focused on management of portal hypertension and relief of biliary obstruction. In patients with noncirrhotic portal fibrosis and symptomatic portal hypertensive biliopathy, portal decompression surgery by proximal splenorenal shunt is one successful treatment option.

Background & Aims: Congenital diarrheal disorders are rare inherited intestinal disorders characterized by intractable, sometimes life-threatening, diarrhea and nutrient malabsorption; some have been associated with mutations in diacylglycerol-acyltransferase 1 (DGAT1), which catalyzes formation of triacylglycerol from diacylglycerol and acyl-CoA. We investigated the mechanisms by which DGAT1 deficiency contributes to intestinal failure using patient-derived organoids.

Methods: We collected blood samples from 10 patients, from 6 unrelated pedigrees, who presented with early-onset severe diarrhea and/or vomiting, hypoalbuminemia, and/or (fatal) protein-losing enteropathy with intestinal failure; we performed next-generation sequencing analysis of DNA from 8 patients.

Chronic granulomatous disease (CGD) is a primary immune deficiency that is commonly diagnosed under the age of 5 years (95%) and is rarely seen in adulthood. CGD may manifest as inflammatory bowel disease (IBD) in childhood. Without proper diagnosis, these patients may be monitored for years as IBD; some may even be regarded as steroid-resistant ulcerative colitis (UC) and end up having a colectomy.
