Active clinical trials for "Hirschsprung Disease"

Hirschsprung's Disease (HD) and anorectal malformations (ARM) are both paediatric diseases of the colon and rectum. Both of these conditions require surgery in order to correct them, frequently needing sections of the bowel to be removed. Some complications of removing parts of the bowel include forming a stricture (a narrowing of the place where the bowel is reattached), and leak from the join. These can be devastating complications, and can significantly impact a patient's quality of life. Indocyanine green (ICG) is a medication that binds to blood vessels and can be visualized using special cameras in the operating room. Once it binds, it "lights up" green on this equipment. This lends the advantage of being able to better see which parts of the bowel get good blood flow. The theory is that good blood flow can reduce the risks of previously mentioned complications. This has been shown to be true in a variety of bowel surgeries in adults. ICG has also been shown to be safe in children. Given that HD and ARM are both relatively rare conditions (~1/5000 live births), research in this area needs to be strategic. The investigators want to ensure that the investigators can recruit enough patients to the study using this protocol such that if this were to be scaled up to a multi-centre trial in the future, the investigators could demonstrate feasibility. The investigators will collect data both on the feasibility of recruitment as the primary outcome and secondary outcomes including stricture, leak, length of stay in hospital, and return to hospital.

The purpose of this study is to assess the efficacy of neuromodulation for treatment of chronic constipation and fecal incontinence in pediatric patients and to evaluate the differences between the invasive vs. non-invasive approach.

Comparison of Circular(Soave)and Heart-shaped Anastomosis in Hirschsprung's disease.

The objective of this prospective study is to compare the diagnostic accuracy of rectal suction biopsy (RSB) compared to full thickness rectal biopsy (FTB) in the diagnosis of Hirschsprungs Disease (HD) in children. The secondary objective to compare cost-effectiveness of the two procedures

The overall aim is twofold: 1) to stretch the borderline regarding the present knowledge of clinical and economic cost-effectiveness of eHealth as an aid for facilitating and supporting self-management in families with long-term childhood illness, and 2) to develop a sustainable multidisciplinary research environment for advancing, evaluating, and implementing models of eHealth to promote self-management for children and their families. A number of clinical studies are planned for, covering different parts of paediatric healthcare. The concept of child-centred care is essential. Experienced researchers from care science, medicine, economics, technology, and social science will collaborate around common issues. Expertise on IT technology will analyse the preconditions for using IT; economic evaluations will be performed alongside clinical studies; and cultural and implementation perspectives will be used to analyse the challenges that arise from the changes in relations among children, family and professionals, which may occur as a result of the introduction of eHealth. Child health is not only important in itself. Investments in child health may also generate significant future gains, such as improved educational and labour market performance. Six complex, long-term and costly challenges in paediatric healthcare are planned for, involving eHealth technology such as interactive video consultation, pictures, on-line monitoring, and textual communication. The research follows an international framework for developing and evaluating complex interventions in healthcare. End-users (families) and relevant care providers (professionals in health and social care) will participate throughout the research process. The overall aim is certainly to analyse eHealth as an aid for facilitating and supporting self-management. However, the plan also includes the research issue whether eHealth at the same time improves the allocation of scarce health care- and societal resources.

Congenital central hypoventilation syndrome (CCHS) is a rare disorder of autonomic and respiratory regulation that frequently alters oxygen delivery to the brain. In CCHS, neurocognitive function has been of great concern because of the potential for repeated hypoxemia and hypercarbia in activities of daily living in addition to hypoventilation with related hypoxemia and hypercarbia during sleep. As the world's leading referral center for CCHS, the Center for Autonomic Medicine in Pediatrics (CAMP) is engaged in ongoing research to identify factors that impact neurocognitive performance in patients with CCHS in order to optimize clinical management and improve long term neurocognitive outcomes. The purpose of this IRB-approved research study is to implement the NIH Toolbox as a standard measurement of cognitive health in patients with CCHS. Further, the study aims to determine how intrinsic and extrinsic disease factors such as age at diagnosis, PHOX2B mutation type and genotype, and nature of past and present artificial respiratory intervention affect the NIH Toolbox Cognitive scores of individuals with CCHS. Eligible participants will complete a 45-minute NIH Toolbox assessment and parents (or adult participants) will complete an associated, 15-minute Research Electronic Data Capture (REDCap) questionnaire.

This study explores the use of an exclusive human milk diet versus standard feeding practices to compare the influence on feeding outcomes and the gut bacteria in infants with intestinal differences.

Approximately 340 babies are born with Hirschsprung's disease (HSCR) or an anorectal malformation (ARM) per year in the UK. Most require corrective surgery in the newborn or early infancy period. In both conditions, there is both variability in the severity of the condition and the type of operative technique used. Many children do well following surgery and have good continence in later life. However a significant proportion of children suffer from a lifetime of constipation or incontinence. This has a significant impact on their social and psychological welfare and is a significant burden on healthcare resources. Due to the variation in practice, there are limited data on long-term outcomes following surgery for children with HSCR or ARMs. Where studies have been performed, they often include small numbers, non-standardised outcome measures and short follow-up periods. It is therefore difficult to ascertain the effectiveness of different management strategies. However, a recent Delphi process has been carried out to establish 10 core measures in HSCR to improve outcome reporting. This research group has a long track record in this research area, specifically in the determination of long-term outcomes of children with HSCR, leading to well cited papers within the literature. In the last 2 decades there has been a significant change in the surgical techniques used in HSCR, however the underlying evidence base for this is still lacking. This study seeks to follow-on from previous studies looking specifically at the long-term outcomes in children with HSCR. Furthermore, the aim is to widen the study to encompass all children treated at Alder Hey and also to use the same methodology to assess long-term outcomes for children with ARMs, as both groups of patients experience similar long term morbidity. This will provide qualitative and quantitative data aiding counselling parents of children with HSCR/ARM.

Hirschsprung's disease (HD) is a rare disease defined as a congenital absence of enteric ganglia, resulting usually in neonatal bowel obstruction. The current treatment is the operative removal of the aganglionic bowel and anastomosis to the ganglionic zone considered as 'healthy'. However, postoperative course remains unpredictable. Functional intestinal disorders are present in up to 45% of patients and can occur in the immediate postoperative period or few weeks/years later. Until now, there are neither predictive factors of postoperative digestive complications nor established treatment for postoperative dysmotility in HD. Abnormalities in enteric nervous system (ENS) phenotype and functions in the 'healthy' ganglionic segment are increasingly suspected to be directly responsible for postoperative intestinal dysfunctions in HD. Therefore, approaches aimed at restoring the nitrergic phenotype could be of major therapeutical interest. Among targets regulating the nitrergic phenotype of ENS are the microbiota and/or derived metabolites. Indeed preclinical animal models deficient in bacterial sensing molecules have a loss of nitrergic neurons and reduced colonic transit. Conversely, microbiota transfer to newborn germ-free mice restored colonic transit time. Alternatively the investigators has shown that bacterial metabolites such as short-chain fatty acids, in particular butyrate, can increase nitrergic phenotype and enhance colonic motility in a gut immaturity animal model. Therefore the investigators hypothesize preoperative butyrate enema will reduce postoperative intestinal complications at short-term and medium/long-term.

With an increasing body of evidence to support a causal link between drinking milk that contain cow's milk protein (CMP) and the development of gastrointestinal disturbance in infants, many clinicians avoid the use of CMP containing feed in high risk babies. Delivery of adequate nutritional intake is one of the great challenges in the care of newborn infants, particularly those born preterm or with gastrointestinal problems. Whilst there are recognised benefits of human milk, a diet of exclusive human milk may not meet the nutritional demands of the infant. To close this gap, breast milk fortifier (BMF) is typically added to human milk. However, addition of BMF may be associated with gastrointestinal disturbance, possibly due to the fact that it contains CMP. This research study is to test the tolerability and safety of a new human milk-based BMF in neonates with gastrointestinal problems. It is hoped that this may provide an opportunity for high risk infants, to receive the benefits of human milk whilst minimising the risks reported to be associated with CMP. Eligible infants will be those in whom nutritional supplementation of breast is deemed clinically necessary, a weight of greater than 1.0kg at the time of starting fortifier and at least one of: previous gastrointestinal surgery congenital gastrointestinal anomaly medically treated gastrointestinal disease previously suspected intolerance of CMP based breast milk fortifier in the absence of other gastrointestinal disease Infants will be started on human milk-based BMF once they are tolerating 100 mls per kilo per day of human breast milk. The human milk-based fortifier will be commenced at half the recommended dose for 48 hours then increase to full strength. This will be continued until the infant reaches 44 weeks corrected gestational age, or until such time as they are deemed to no longer require the additional nutrition.
