Evidence-based recommendations for functional constipation in infants and children
(Faculty of Medicine, University of Kelaniya, Sri Lanka, 2016) Benninga, M.
Chronic constipation is a common problem in childhood with an estimated prevalence of 3% in the Western world and is probably the most common gastrointestinal complaint in children. According to the ROME-III criteria, functional constipation is defined as a child experiencing 2 or more of the following symptoms: 1) two or fewer defecations in the toilet per week, 2) at least one episode of fecal incontinence per week, 3) stool retentive posturing, 4) painful or hard bowel movements, 5) presence of a large fecal mass in the rectum or 6) large diameter stools that may obstruct the toilet without objective evidence of a pathological condition. Infants up to 4 years of age have to fulfill two or more criteria for at least 1 month while children older than 4 years need at least 2 months of symptoms. Only less than 5% of children with constipation have an underlying disease. In the majority of patients, constipation is difficult to treat and often a long-lasting problem. Up to 50% of children followed for 6-12 mo continue to have symptoms and need ongoing laxative use. Two evidence-based guidelines (the Netherlands and Great Britain) have been developed concerning the diagnostic and therapeutic approach for childhood constipation. To assist healthcare workers worldwide in the management of children with functional constipation, only recently the North American Society for Pediatric Gastroenterology and Nutrition (NASPGHAN) and the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) decided to develop an evidence-based guideline as a joined effort. At present, a thorough medical history and complete physical exam are usually sufficient to confirm the diagnosis of functional constipation. Further laboratory or radiological investigations should only be performed in case of doubt, to exclude an underlying disease. Treatment of childhood constipation consists of four steps: (1) education, (2) disimpaction, (3) prevention of re-accumulation of faeces and (4) follow-up. Surprisingly, there is only limited evidence that laxative treatment is better than placebo in children with constipation. According to the available evidence, lactulose is recommended for children <1 year as first-choice treatment. For children older than 1 year, both lactulose and polyethylene glycol (PEG) with or without electrolytes can be used as first-choice treatment.
Imaging in pediatric disorders of the gut-brain interactions: current best practice and future directions
(Taylor and Francis Group, 2023) Rajindrajith, S.; Hathagoda, W.; Ganewatte, E.; Devanarayana, N.M.; Thapar, N.; Benninga, M.
INTRODUCTION: Disorders of Gut-Brain Interactions (DGBI) are a common clinical problem in children and pose significant challenges to the attending pediatrician. Radiological investigations are commonly ordered to evaluate these children. AREA COVERED: This review focuses on the current best practice of using radiological investigations in DGBIs and how novel radiological investigations could revolutionize the assessment and therapeutic approach of DGBI in children. EXPERT OPINION: We believe imaging in DGBI is still in its early stages, but it has the potential to revolutionize how we diagnose and treat children with DGBI. As the understanding of the gut-brain axis continues to grow, we can expect to see the disappearance of conventional imaging techniques and the emergence of more sophisticated imaging techniques with less radiation exposure in the future which provide more clinically meaningful information regarding the gut-brain axis and its influence on intestinal function. Some of the novel imaging modalities will be able to broaden our horizon of understanding DGBI in children providing more useful therapeutic options to minimize their suffering.
