Filter by:Children with chronic constipation, suspected of having hirschsprungs disease, who are admitted for rectal biopsy will be included in the study. During the procedure, electrophysiological reading from the site chosen for biopsy will be done. Correlation between electrophysiological data and histopathology will be analyzed.
3D high resolution anorectal manometry (3DHRAM) is the most precise tool to assess function and 3D topographic picture of pressures along the anal canal. Until now, it has been used only in adult population to evaluate defecatory disorders. Congenital anorectal disorders are severe conditions and may present wide spectrum of symptoms from gastrointestinal tract. The usefulness of the 3DHRAM hasn't been evaluated in children after surgery for anorectal disorders such as Hirschsprung's disease and anorectal malformations. It may help for better understanding of pathophysiology of anorectal area and allow for planning improved procedures in these patients. Moreover, the investigators study may elucidate the real usefulness of the procedure in management of disorders of gastrointestinal tract in pediatric population.
Comparison of Circular(Soave)and Heart-shaped Anastomosis in Hirschsprung's disease.
1. The investigators previously reported a simple diagnostic scoring system to differentiate Hirschsprung disease (HD) from Hirschsprung disease allied disorders (HAD) in the patients with suspected intestinal dysganglionosis. In the retrospective study, the investigators concluded that the patients with a predicting score of more than 5 are more likely to be diagnosed with HD, whereas a score less than 5 is mostly indicative of HAD. 2. Since it is essential to confirm the accuracy and efficacy of the scoring system in a prospective manner before it is used as a standard procedure, this prospective study is designed and performed.
To identify demographic, clinical, genetic, immunologic and/or microbial (i.e., fecal stream characterization) risk factors that influence the likelihood of development of the HAEC phenotype in children who carry the diagnosis of HD. The newly formed HAEC Collaborative Research Group (HCRG) will utilize the 4 participating centers in the current consortia and recruit additional centers to enroll children diagnosed with Hirschsprung disease. 1a: To recruit 200 patients with Hirschsprung disease without HAEC. 1b: To recruit 200 patients with Hirschsprung disease and HAEC using standardized diagnostic criteria by collaborating with participating members of the HAEC Collaborative Research Group[1]. 1c: To collect clinical and demographic information from well-characterized HD patients both with and without HAEC. 1d: To collect samples blood for DNA for genome wide association study (GWAS) by high throughput SNP technology and mutational analysis of known HSCR genes. 1e: To collect serum samples at the time of recruitment in a subset cohort (n=50 HD only, n=50 HD + HAEC) for serological immune markers known for inflammatory bowel disease (IBD) including ANCA, ASCA, OMPC, I2, and CBir1 and any newly identified markers. 1f: To collect and store fresh fecal specimens for future evaluation by molecular methodologies to determine relative proportions of enteric microflora in a subset cohort (n=50 HD only, n=50 HD + HAEC) of children (<18 years). 1g: To establish a Centralized Data Coordinating Center for data collection, data quality and detailed data analyses (CSMC) and tissue bank (CSMC) to facilitate specimen analysis for this study. The HAEC risk factor identification will be completed by multivariate logistic regression analysis. Genetic association will be studied for each SNP in the GWAS together with all other potential risk factors. Further analysis will be carried out to evaluate multiple SNPs/genes simultaneously.
The present study was designed to compare the efficacy of conservative treatment to operative treatment for improvement of constipation symptoms in infants with short or normal-segment Hirschsprung disease.
Enterocolitis(EC) is the most common and serious postoperative complication of Hirschsprung's disease(HD) with high morbidity and mortality. Probiotics are live microbes that, when administered in adequate amounts, confer health benefit to the host.Based on this previous knowledge on the beneficial effects of probiotics during pro-inflammatory conditions of the gastrointestinal tract, investigators hypothesized that oral probiotics could decrease the incidence and severity of Hirschsprung's disease associated enterocolitis(HAEC).Investigators conducted a prospective, multicenter, randomized and controlled trial to assess whether oral probiotics could decrease the incidence and severity of Hirschsprung's disease associated enterocolitis(HAEC).
Hirschsprung's disease is a complex genetic disorder. The etiology of this disease is not completely understood. It is characterized by the absence of ganglia (nerve cells) in de distal colon. This impairs bowel relaxation which can lead to bowel disfunction, toxic megacolon, ileus and enterocolitis. So far, several genes have been identified that play a role in Hirschsprung's disease. The precise mechanisms however, remain unclear. This study wants to identify new mutations and hopefully clarify more about the etiology of the disease.
CoRDS, or the Coordination of Rare Diseases at Sanford, is based at Sanford Research in Sioux Falls, South Dakota. It provides researchers with a centralized, international patient registry for all rare diseases. This program allows patients and researchers to connect as easily as possible to help advance treatments and cures for rare diseases. The CoRDS team works with patient advocacy groups, individuals and researchers to help in the advancement of research in over 7,000 rare diseases. The registry is free for patients to enroll and researchers to access. Visit sanfordresearch.org/CoRDS to enroll.
Patients undergoing routine rectal suction biopsy will undergo as part of the study an additional Endoscopic mucosal resection. The biopsy results will also be correlated with patient's clinical data including clinical history, Bristol stool scale, anorectal manometry results, and SITZ marker studies. Cost and recovery time will be compared.
