3D High Resolution Anorectal Manometry in Children After Surgery for Anorectal Disorders

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 ...

Phase N/A

POEM Trial: Multi-center Study Comparing Endoscopic Pneumodilation and Per Oral Endoscopic Myotomy (POEM)

The aim of the study is to compare the efficacy of per-oral endoscopic myotomy (POEM) to the efficacy of pneumodilation as the initial treatment of symptomatic idiopathic achalasia. It is hypothesized that POEM has a higher long-term efficacy than pneumodilation in treatment of therapy-naive patients with idiopathic achalasia.

Phase N/A

Hirschsprung Disease Genetic Study

Hirschsprung disease (HSCR) is a birth defect resulting from the absence of nerve (ganglion) cells in the gastrointestinal tract. Hirschsprung disease has a population incidence of 1/5000 live births and most often occurs as an isolated condition. However, approximately 30% of HSCR cases are associated with other birth defects such ...

Phase N/A

Identification Genetic Immunologic and Microbial Markers of Hirschsprung Associated Enterocolitis in Children With Hirschsprung Disease

Emerging data suggests that the distinct phenotype of HAEC in children with HD may be the result of the complex interplay between host genetics, immune response and environmental triggers. Data suggest that approximately 20-30 percent of patients with HD develop HAEC. Thus, well-designed, multi-disciplinary investigations of genetic, immune and microbial ...

Phase N/A

Genetic Mosaicism in Hirschsprung's Disease

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 ...

Phase N/A

Minimally Invasive Surgery of the Gastro-esophageal Junction

This study will assess short and long term outcomes of individuals undergoing minimally invasive surgery of the gastro-esophageal junction (MISGEJ). Patients will respond to questionnaires on an annual basis evaluating quality of life and functionality following MISGEJ. Hospital charts will also be reviewed on an annual basis to assess patient ...

Phase N/A

POEM- Peroral Endoscopic Myotomy for Esophageal Motility Disorders

POEM has recently described as an alternative treatment for achalasia in humans. In this procedure the esophageal sphincter is incised through a submucosal tunnel in the esophagus. In this study we aim to perform POEM on achalasia patients.

Phase N/A

Outcome of Symptoms in Patients Undergoing a Heller Myotomy

Patients will answer questionnaires before and after surgery to evaluate their symptoms of achalasia and will also have their charts reviewed for relevant medical information.

Phase N/A

Esophageal Cancer Risk Registry

We will enroll patients with esophageal cancer, patients who are at risk for developing esophageal cancer, and patients who have a non-cancerous esophageal disorder. All patients will be asked to fill out a questionnaire about their general health and personal habits, and about their relatives' medical history; this will be ...

Phase N/A

Anterior Orientation vs Posterior Orientation in Per Oral Endoscopic Myotomy POEM for the Treatment of Achalasia

Achalasia is one of the most studied esophageal motility disorders. The etiology of Achalasia is autoimmune, neurodegenerative, or viral immune. Achalasia is a consequence of the degeneration of ganglion cells in the myenteric plexus of the esophageal body and the lower esophageal sphincter (LES). The end result of the inflammatory ...
