Gastroparesis Registry 4
The Gastroparesis Registry 4 (GpR4) is an observational study of patients with symptoms of gastroparesis (Gp) and functional dyspepsia (FD) with either delayed or normal gastric emptying. To better understand these disorders, this registry will capture demographic, clinical, physiological, questionnaire, and patient outcome data to characterize the patients and their clinical course. Participants will complete several questionnaires, complete a nutrient drink test and have a gastric emptying study.

Advanced GastroInstestinal(GI) Surgery Training in Residency and Fellowship.
The aim of this anonymous survey is to identify who teaches GI procedures to general surgical residents during residency training and understand the need as well as desire for an Advanced Surgical GI fellowship amongst senior surgical residents. We also hope to identify the self-reported level of comfort of senior general surgery residents in completing both common and complex GI procedures.

Endoscopic Retrograde Cholangiopancreatography
The risk of post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis(PEP) is influenced by patient and procedure-related factors. Strategies to decrease PEP(Post-Endoscopic Retrograde Cholangiopancreatography Pancreatitis) are of great importance.

Video Tutorial and Oral Explanation Vs Oral Explanation Alone in Colonoscopy Preparation
Colonoscopy which is the standard examination for the exploration of the colon and rectum is performed very frequently. Colon preparation before the examination is an essential step and pescription of the colonic preparation is carried out by the gastroenterologist. However, despite a standardized explanation of the colon preparation, there is heterogeneity in understanding the colonic preparation, which in some cases compromises the quality of the colonoscopy examination. This clinical study aims to investigate whether an explanation of colonic preparation by tutorial films would increase the quality of colon preparation and would reach the recommendations of the Société française d'endoscopie digestive (SFED) in 2019.

Undiluted and Diluted Nutrition
Adult patients after elective major abdominal surgeries who are planned to be admitted to the Intensive Care Unit (ICU) can be included in the trial. Each patient will be fed via the gastrointestinal tract. Half of the patients will receive enteral nutrition (EN) with additional fluids, and the rest will receive undiluted EN. The primary aim of this study is to assess feeding intolerance in both patient groups.

Biological Sample Repository for Gastrointestinal Disorders
The goal of this observational study has the purpose of collecting biological samples from obese patients undergoing evaluation for weight loss by means of medical or endoscopic therapies; and of post bariatric surgery patients presenting with short- and long-term surgical complications. The aim is to enhance the overall understanding of the mechanisms leading to obesity, weight loss, failure to lose weight, and weight regain following treatment. Additional goals are to determine the efficacy of endoscopic and surgical procedures, to identify potential therapeutic targets and disease biomarkers that predict response to therapy.

MTT for Children With ASD Who Have Gastrointestinal Disorders
The investigators propose to investigate Microbiota Transfer Therapy (MTT) for treating children with Autism Spectrum Disorder (ASD) and gastrointestinal problems (primarily constipation and/or diarrhea). MTT involves a combination of 10 days of oral vancomycin (an antibiotic to kill pathogenic bacteria), followed by a bowel cleanse, followed by 12 weeks of Fecal Microbiota (FM).

Microbiota Transplant Therapy for Children With Both Autism Spectrum Disorder and Gastrointestinal Disorders
The investigators propose to investigate Microbiota Transfer Therapy (MTT) for treating patients with Autism-spectrum disorder with Gastrointestinal disorders (constipation, diarrhea, and/or abdominal pain). MTT involves a combination of 14 days of oral vancomycin (an antibiotic to kill pathogenic bacteria), followed by 1 day of bowel cleanse using Miralax, followed by 5 days of high dose MTP-101P with an antacid, followed by 12 weeks of a lower maintenance dose of MTP-101P with an antacid.

Healthy Stool Volunteer Donors for Fecal Microbiota Transplantation Trials
Currently, ANSM recommendations govern FMT (Fecal Microbiota Transplantation) in clinical trials. The collection and validation of these stool donations as part of the trials is complex and not very efficient. It therefore seems essential to identify the limiting factors and the characteristics of Healthy Volunteer Donors to optimize the number of valid stool donations.

ctDNA-guided Surveillance for Stage III CRC, a Randomized Intervention Trial
IMPROVE-IT2 is a randomized multicenter trial comparing the outcomes of ctDNA guided post-operative surveillance and standard-of-care CT-scan surveillance. The hypothesis of this study is that ctDNA guided post-operative surveillance combining ctDNA and radiological assessments could result in earlier detection of recurrent disease and identify more patients eligible for curative treatment.

The Gut-Lung Axis and Respiratory Illness in Children
The goal of this single-centre observational study conducted at the Royal Hospital for Children in Glasgow, Scotland, is to employ a multi-omics approach to investigate the "gut-lung axis" in health and disease. Part A is a cross-sectional study design investigating the postulated bidirectional link between the gut and lung microbiomes in children suffering from respiratory or gastrointestinal conditions. Children with no GI or respiratory issues attending for orthopaedic care will be used as a benchmark for a healthy gut-lung axis. The main questions we aim to answer are: * What does a healthy gut-lung axis look like? * Do children with respiratory issues show an altered gut microbiome? * Do children with GI issues show an altered lung microbiome? Part B is a longitudinal study design, that aims to assess the effects of biologics on the gut-lung axis by comparing the gut and lung microbiomes in children with asthma at two time-points who are indicated to start biologics therapy (Asthma treatment) or will not receive biologics therapy (asthma control). Participants will provide: * airway samples (to investigate the lung microbiome) * blood samples (to assess inflammatory and metabolic factors which may mediate communication between the two sites) whilst under general anaesthetic for a treatment related to their standard of care * stool samples (to assess gut microbiome) * dietary information (food diary and/or food frequency questionnaire) to assess relationships between diet and the gut-lung axis.

The Gut-Brain Study
The purpose of this study is to find out if transplant of fecal matter (stool), also known as fecal microbiota transplantation (FMT), from a healthy person into the intestines of children and young adults with Autism Spectrum Disorder (ASD). For this study children between the ages of 5-17years will be recruited over 2 years. Children will be recruited who receive an ASD diagnosis using the gold-standard Autism Diagnosis Observation Schedule -2 (ADOS-2) using module 1, 2 or 3 (none, limited or no moderate expressive language). Children diagnosed with these modules of the ADOS-2 may be at greater risk for GI disorders and rigid-compulsive behaviors. Additional assessment of rigid-compulsive behaviors and social communication will be done using the Repetitive Behavioral Scales-Revised (RBS-R) and Social Responsiveness Scale-2 (SRS-2), respectively. KBIT (the Kaufman Brief Intelligence Test) is used at baseline to obtain patient IQ. Total evaluation time is approximately 90 minutes. Following baseline symptom evaluation, a medical exam will be performed to determine whether each child is expressing specific GI symptoms. In addition, parents will fill out the Questionnaire for Pediatric Gastrointestinal Symptoms- Rome III (QPGS-III). Once an ASD diagnosis is confirmed, FMT treatment will be initiated, which typically occurs within 4-6 weeks of the initial diagnosis. Half 50% of the children (n=5) will receive the equivalent of 50 g of stools from a healthy donor into the jejunum through upper endoscopy and the other 50% off children (n=5) will receive Saline solution as Placebo control through upper endoscopy. Subjects will have a total of 5 visits within 24 weeks including phone call follow up on Day 7 after FMT.
