E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Colonoscopy is considered the reference standard for detection of colonic neoplasia. Polyp detection is dependent on quality standards including colonoscopist and patient related factors. Optimal bowel preparation is associated with lower polyp miss rates. Improving tolerability of bowel cleansing may encourage patient compliance. Lowering the intake of bowel preparation would increase patient tolerability. We hypothesize that the small dose Picoprep is as efficacious for bowel cleansing as small dose Moviprep (PEG) and that Picoprep is as safe as Moviprep and may be more tolerable for patients. |
Coloscopie is de standaard voor de detectie van darmkanker en darmpoliepen. Het ontdekken van poliepen is afhankelijk van de ervaring van de endoscopist en de voorbereiding van de patient. Optimale darmvoorbereiding is geassocieerd met het minder missen van poliepen maar wel een belasting voor de patient. Vermindering van het in te nemen volume zal de patiententrouw doen toenemen.We veronderstellen dat een de verminderde dosering bij het gebruik van picoprep en moviprep dezelfde goede voorbereiding zal geven en dezlefde veiligheid, maar dat de kleinere dosis van picoprep de acceptatie van de patient zal vergroten. |

Veiligheid voor de patient door afname van bloed en nabellen |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patient 18 years and older, who have to uindergo a colonoscopy and who are able to give their informed consent and are eligible to undergo bowel-cleansing |
Patienten ouder dan 18 jaar bij wie een indicatie bestaat voor coloscopie en die in staat zijn hun informed consent te geven en die de darmvoorbereiding kunnen ondergaan |
|
E.4 | Principal exclusion criteria |
Patients with significant gastroparesis or gastric outlet obstruction; ileus; known or suspected bowel obstruction or perforation; severe chronic renal failure (creatinine clearance < 30mL/minute); severe congestive heart failure (AHA class III or IV); toxic colitis or megacolon. Also, patients with a subtotal colectomy or a colostomy will be excluded because of insufficient remaining colonic surface to evaluate the effects of bowel cleansing. |
Patienten met significant gastroparese of maaguitgangsstenose; ileus; bekende of vermoede darm obestructie of perforatie; ernstig nierlijden (kreatinine klaring < 30mL/minute); ernstig hartfalen (AHA classe III or IV); toxische colitis of megacolon. Patienten met een subtotale colectomie of een colostoma worden uitgesloten omdat er te weinig overblijvend darmoppervlakte is voor een effectieve beoordeling. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
Preparation efficacy is evaluated by the blinded colonoscopist. Bowel preparation is assessed by the validated Ottawa Bowel Preparation Scale and the Boston Bowel Preparation Scale based on the preparation scores from three segments of the colon (right colon, transverse colon and left colon), as well as a score for overall colonic fluid. A questionnaire is used to assess tolerance of the bowel preparation. This questionnaire is will assess items as bloating, cramping, nausea and overall burden. All items are scored on a 5-point Likert scale. |
De darmvoorberiding wordt blind door de endoscopist beoordeeld aan de hand van 2 gevalideerde vragenlijsten (Ottawa Bowel Preparation Scale and the Boston Bowel Preparation Scale) die de 3 segmenten van het colon (rechter, transversum en linker) colon scoren en een score geven voor de hoeveelheid vocht. tevens wordt met een vragenlijst de tolerantie van de darmvoorbereiding zoals opgeblazen gevoel, misselijkheid, braken, belasting inschatten op een 5-punts Likert schaal. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Endoscopist once after the colonoscopy, patient once after taking the preparation. |
De endoscopist direct na de coloscopy, de patient na inname van de darmvoorbereiding |
|
E.5.2 | Secondary end point(s) |
Adverse events will be recorded for 30 days after colonoscopy. Blood will be collected after the prep and right before the procedure to assess electrolyte shifts and tested for bicarbonate, blood urea nitrogen, calcium, chloride, creatinine, magnesium, phosphate, potassium, sodium, haemoglobin and hematocrite. |
Compliacties worden gedurende 30 dagen na de coloscopie opgevolgd. Bloed wordt afgenomen voor de start en na het voltooien van de voorbereiding en onderzocht op bicarbonaat, ureum, calcium, chloor, kreatinine, magnesium, fosfaat, kalium, natrium, haemoglobine and hematocriet. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Blood sampling twice and a telephone call after 30 days |
Tweemaal bloedafname en een telefonische afspraak na 30 dagen. |
