Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years and Over|
Inclusion Criteria:- Adult outpatients (18 years or older) - routinely referred for small bowel video capsule endoscopy (CE)
Exclusion Criteria:- dysphagia - severe gastroparesis requiring endoscopic placement of capsule - small bowel obstruction - pregnancy
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

In order to determine the best method for bowel preparation before Capsule Endoscopy, this study seeks to determine in patients undergoing small intestine Capsule Endoscopy if split dose Polyethylene Glycol or single morning dose of Polyethylene Glycol have a benefit in Visualisation quality when compared to clear fluids only. A co-primary outcome will also be the diagnostic yield, as measured by the aggregate of all the active preparation groups compared to than clear fluids only group. Secondary outcome measures will include tolerance of preparations, cleanliness as assessed by a validated 4 point scale, distal small bowel visualization (the last 1/4 of small bowel examination by time) and small bowel transit time (measured as time from first duodenal image to first cecal image). Group Assignment: The groups will have some common instructions: all groups will be instructed to stop iron supplements five days prior to the exam. On the day prior to the exam, patients will be instructed to have a light breakfast and lunch, followed by only clear fluids. Over the day, patients will be encouraged to have at least two litres of clear fluids. On the day of the exam, 80 mg of oral simethicone will be given 10 minutes prior to the exam. The capsule will be ingested at 9:00am, after which fluids may be consumed 2 hours later, and solid food 4 hours later. Patients will be randomly assigned to in a one to one fashion to one of three groups using a central online randomization program. The groups for this project include: A. Control: no additional instructions beyond those above will be given. B. Single dose Polyethylene Glycol: Patients will take 2 litre of Polyethylene Glycol at 6am the day of the exam. C. Split dose Polyethylene Glycol: Patients will take 1 litre of Polyethylene Glycol at 7pm the evening prior to the exam and 1 litre at 6am the day of the exam. Recruitment of patients will be performed from outpatient gastroenterology clinics at Sheffield Teaching Hospitals NHS Trust. After a request for Capsule Endoscopy from a referring physician, the patient will be contacted by telephone by one of the Capsule endoscopy nurse specialists (who are also involved in the study) as per normal practice. The study will be discussed, the procedure explained and a convenient date for the procedure will be agreed with the patient. The patient will be invited to meet with one of the research staff at a mutually agreed time in order to go through the study once more and provide written consent should they agree to participate. Should they wish to participate but would prefer to complete a postal consent form, this will be arranged. The procedure will be completed according to normal practice. Patients will be advised that they can withdraw from the study at any point and choose a preferred option for bowel preparation
