To validate the performance of the Poseidon System™ for fluid management during water-aided endoscopic procedures in the colon.
The purpose of this project is to examine the role of machine learning and computer aided diagnostics in automatic polyp detection and to determine in real-time how a computer-aided detection (CADe) algorithm will perform when compared to standard screening or surveillance colonoscopy alone. Design will be a multi-center, prospective, unblinded randomized tandem colonoscopy study. 196 patients referred for either screening or surveillance colonoscopy will be included.
To compare intracorporeal and extracorporeal anastomoses for robotic-assisted and laparoscopic right colectomies
The purpose of this study is to determine if the trendelenberg (TD) position (position in procedures that involves placing the patient at an angle so that their head is lower than their feet on the procedure bed) in select patients undergoing colonoscopy is superior than the left lateral (LL) position (patient laying on their side, traditionally used for colonoscopies) in terms of decreasing time necessary to pass the colonoscope through the left colon, and decreasing the difficulty of the procedure.
The aim of the study is to determine if more force is used during colonoscopy when patients receive monitored anesthesia with propofol versus conscious sedation. Force measurements will be performed using the colonoscopy force monitor (CFM). This device measures the magnitude and direction of force applied to the insertion tube of a standard colonoscope during colonoscopy.
This study will evaluate the expansion of dietary options from clear liquids the entire day to a low reside breakfast and lunch for patients prior to undergoing bowel preparation with MoviPrep® and its effect on preparation quality for colonoscopy.
This feasibility trial will evaluate the ability of the SuMO Tissue Access and Resection System (Apollo Endosurgery, Austin, Texas). The SuMO System utilizes balloons to create a submucosal pocket and electrosurgical cutting device to resect the mucosa. The SuMO elevates the tissue from the underlying muscularis using a balloon to distend the submucosa, similar to what is currently performed with injectable saline in a standard EMR. After dissection of the lesion, a separate cutting device will be utilized to resect the tissue by cutting around the border of the targeted tissue. If needed, a standard loop snare will be used to complete the mucosal resection.
The purpose of this study is to improve the investigators understanding of different training methods in laparoscopic colon surgery.
The purpose of this study is to determine: 1. What quantity of bacteria is spilled into the abdomen during a colon resection 2. If there is a correlation between the quantity and post-operative infection 3. What intralumenal pressure is generated when testing the colonic anastomosis for air leak
To evaluate the performance of PillCam COLON 2 in regards to detection of patients with polyps where colonoscopy is considered as the gold standard reference.
The purpose of this research is to compare two different standard of care surgical methods for the following large bowel (colon) procedures: laparoscopic right colectomy, total colectomy, and left colectomy. The study will compare electrocautery, used with surgical clips and/or surgical staplers, and the Ligasure vessel sealer. The investigators will be looking at which procedure is faster and more cost efficient and the investigators will calculate hospital expenses for the two groups to make comparisons.
This multi-center, prospective, cohort study of 394 subjects that are indicated for standard colonoscopy due to suspected or known colonic disease examines the Given Diagnostic System and the PillCam Colon Capsule in comparison to standard colonoscopy. This study aims a. To evaluate and compare the accuracy of PillCam ™ Colon capsule endoscopy (PCCE) with standard colonoscopy. This study will evaluate the safety of PillCam ™ Colon capsule endoscopy (PCCE)
1.1 To collect pathological tumor specimens of patients with metastatic colorectal cancer in a prospective fashion for correlative studies of response to an oxaliplatin based chemotherapy regimen. 1.2 To determine a gene expression profile that predicts response to an oxaliplatin based chemotherapy regimen in this cohort of patients.
Chronic abdominal pain is common among children, and the majority of cases are attributed to functional abdominal pain disorders. One approach to treating these disorders is by using psychological therapies. This clinical trial aims to see how well pre-recorded guided imagery therapy sessions help children's abdominal pain when delivered via a mobile application (app) on a smartphone or tablet. Participants will complete a baseline abdominal pain and stooling diary to determine eligibility and other surveys. Participants who qualify will be placed in one of two groups by chance: * Immediate Treatment Group * Delayed Treatment Group After randomization, the Immediate Treatment Group will get immediate access to the guided imagery therapy (GIT) mobile app intervention. This intervention asks participants to listen to a 10- to 15-minute GIT session 5 out 7 days weekly for 8 weeks in addition to their usual care for their abdominal pain. Then, participants will complete another abdominal pain and stooling diary and other psychometric surveys at the end of this intervention period. After randomization, the Delayed Treatment group will be observed as they wait 8 weeks without app access. During this phase, these participants will continue to treat their abdominal pain in their usual fashion. After the end of this waiting period, participants will complete another abdominal pain and stooling diary and psychometric surveys again before gaining access to the GIT mobile app intervention. As noted previously, the mobile app intervention will ask participants to listen to a 10- to 15-minute GIT session 5 out of 7 days weekly for 8 weeks in addition to their usual care for their abdominal pain. Another abdominal pain and stooling diary and other psychometric surveys will be collected at the end of this app intervention.
The CRC DRAW study will assess the sensitivity and specificity of the blood-based, Next-Gen CRC Screening Test for the detection of CRC.
This study will evaluate the efficacy and safety of alectinib in participants with Anaplastic Lymphoma Kinase (ALK)-positive locally advanced or metastatic solid tumors other than lung cancer.
The PREEMPT CRC study is a prospective multi-center observational study to validate a blood-based test for the early detection of colorectal cancer by collecting blood samples from average-risk participants who will undergo a routine screening colonoscopy.
The purpose of this study is to determine the safety and tolerability, describe the dose-limiting toxicities (DLTs), and determine the maximum tolerated dose (MTD) (or the highest protocol-defined dose level in the absence of establishing an MTD) of ibrutinib in combination with pembrolizumab in participants with advanced, refractory colorectal cancers.
This is a Phase 1/2, open-label, first-in-human (FIH) study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antineoplastic activity of pralsetinib (BLU-667) administered orally in participants with medullary thyroid cancer (MTC), RET-altered NSCLC and other RET-altered solid tumors.
The purpose of this study is to determine the safety and tolerability of administration of multiple ascending doses of KHK4083 and to select the highest dose tolerated by subjects with moderately active Ulcerative Colitis (UC) followed by a Long-term Extension Therapy (LTE) phase for eligible subjects with a clinical response.
The primary objective of this study is to gather stool samples from subjects with inflammatory bowel disease (IBD) to be added to a test set of stool samples that will be utilized to help select molecular markers and determine the optimal sensitivity and specificity values for the Exact IBD-ACRN surveillance test for colorectal cancer (CRC).
The primary objective of this study is to obtain de-identified, clinically characterized, stool and plasma specimens for use in assessing new markers for the detection of neoplasms of the digestive tract.
This is a study examining the effects of different educational-motivational materials about colorectal cancer screening on perceptions and intentions to get screened. Eligible participants will be randomized to one of three experimental conditions. All participants will be provided information about colon cancer and screening options based on the Centers for Disease Control and Prevention Screen for Life materials. Some participants also will be asked to read a personal narrative about colon cancer screening. This study will determine whether participant's perceptions about and colorectal cancer screening intentions and behaviors differ by which information they read. Participants will complete surveys before, immediately after, and one month after randomization. To assess behavior change, as suggested by grant reviewers and the project officer, we added 6 and 12 month follow up surveys. Participants can complete all study requirements through the study website: http://HealthStudy.wustl.edu
GIC-1001 is a novel, orally-administered, colonic analgesic drug developed as an alternative to i.v. sedation during full colonoscopy. It will be evaluated for efficacy and safety in a multi-center, randomized, double-blind, placebo controlled, dose-ranging, proof of concept Phase 2a trial. Up to 240 patients will receive one of 3 doses of GIC-1001 or its matching placebo. A pharmacokinetic evaluation will be carried out on a subset of patients (N: 24).
The objective of this study is to confirm the sensitivity and specificity of a stool DNA test for detection of colorectal cancer and pre-cancer.
The primary objective is to determine the sensitivity and specificity of the Exact Colorectal Cancer (CRC) screening test for colorectal cancer, using colonoscopy as the reference method. Lesions will be confirmed as malignant by histopathologic examination. The secondary objective is to compare the performance of the Exact CRC screening test to a commercially available FIT assay, both with respect to cancer and advanced adenoma. Lesions will be confirmed as malignant or precancerous by colonoscopy and histopathologic examination.
The objective of this study is to confirm the sensitivity of a stool DNA test for detection of colorectal cancer and pre-cancer. Another objective is to provide anonymous, clinically characterized specimens for a bio-repository for future colorectal cancer-related test development.
The research project addresses the following hypotheses (A) the normal balance of beneficial and detrimental commensal intestinal bacteria is deranged in IBS, with selective alterations in clinically defined patient subsets i.e., diarrhea predominant IBS (D-IBS) and post-infectious IBS (PI-IBS); (B) these changes in intestinal microflora are associated with sub-clinical mucosal inflammation and activation of the mucosal immune system; and (C) activation of the mucosal immune system leads to alterations in gastrointestinal (GI) functions (i.e., motility and sensation) and functional symptoms.
This study is designed to evaluate the safety and effectiveness of an investigational drug, TRN-002 (crofelemer) to relieve the symptoms of diarrhea-predominant irritable bowel syndrome (IBS).
The primary purpose for this study is to compare clinical treatments for patients with functional bowel disorders (irritable bowel syndrome, abdominal pain, painful constipation) in women. We also plan to: 1) determine what clinical features (medical or psychological) determine which patients will improve to these treatments, and 2) understand if there are any physiological features that relate to improvement in symptoms and response to the treatments. We will compare a psychological treatment (cognitive-behavioral therapy - CBT) with education/attention placebo, and an antidepressant drug (desipramine) with a pill placebo. This is the first large-scale study designed to determine the therapeutic effects of these methods, and to also determine interactions among physiologic measures, psychologic and sociodemographic factors, severity of symptoms, and therapeutic improvement including quality of life.
