E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The purpose of the study is to investigate the effect of maintenance treatment with macrogol 3350 + electrolytes (PEG 3350 + E) in the treatment of childhood constipation in a randomized, placebo-controlled design. |
Formålet med studiet er at undersøge effekten af vedligeholdelsesbehandling med polyethylen glycol 3350 (PEG) til børn med simpel obstipation i et randomiseret, dobbeltblindet, placebokontrolleret design. |

- Changes in stool frequency, fecal incontinence episodes and abdominal pain.
|
•Forbrug af studiemedicin.

E.3 | Principal inclusion criteria |
• Referred children to the pediatric out patient clinic with either constipation or fecal incontinence, age 2 to 16 years.
• Children must meet the ROME III criteria. This means that children below 4 years must meet at least 2 of the following criteria during a month, children above 4 years must meet at least 2 of the criteria at least once a week for 2 months:
• Two or fewer bowel movements weekly.
• More than one episode of fecal incontinence weekly.
• Painful defecation.
• Occasional passage of large stools.
• Display of retentive posturing and withholding behavior.
• Large stools in the rectum identified by digital examination or palpable on abdominal examination.
Rome III criteria is developed by scientists and widely internationally accepted among research in childhood constipation.

Børn henvist til børneafdelingen med obstipation mellem 2 og 16 år.
Børnene skal opfylde ROME III kriterierne for funktionel forstoppelse:
ROME III kriterierne
Børn under 4 år skal opfylde minimum 2 af nedenstående kriterier igennem en måned, børn over 4 år skal opfylde minimum 2 af kriterierne mindst én gang om ugen igennem 2 måneder.
• To eller færre afføringer/uge.
• Fækal inkontinens mere end en gang om ugen.
• Smertefuld defækation.
• Passage af store mængder afføring der kan obstruere toilettet.
• Adfærd med tilbageholdelse af afføring.
• Stor mængde fæces i ampullen ved rektaleksploration.
Rome III kriternerne er internationalt udviklede og accepterede kriterier mhp. at opnå sammenlignelige studier af bl.a. obstipation hos børn.
|

E.4 | Principal exclusion criteria |
Children not eligible for participation is children who receive treatment with medications known to affect bowel function, apart from laxatives, within a 2-month period and children e.g. with known organic causes of constipation including Hirschsprung disease, previous surgery on the colon or inflammatory bowel disease. |
Barnet kan ikke inkluderes, hvis det er i behandling med medicin som er kendt for at påvirke tarmfunktionen, fraset laksantia, inden for en 2 måneders periode, eller hvis barnet lider af anden gastrointestinal sygdom som f.eks. mb. Hirschsprung, tidligere operation på colon eller inflammatorisk tarmsygdom. |
