Further Details

Primary Outcome Measures:

  • The average number of spontaneous complete defaecations per week recorded over the period of treatment between scheduled visits.

Secondary Outcome Measures: Assessment of:

  • abdominal pain
  • amount of stool
  • faecal form (Bristol stool scale)
  • rectal bleeding
  • pain on defaecation
  • straining on defaecation
  • stool withholding
  • faecal incontinence (soiling)
  • efficacy (investigator and parental assessment)
  • concomitant laxative treatment

All patients were screened at Day 0 (Visit 1) when baseline assessment of their bowel movements over the previous 14 days were made. Patients were dispensed with Movicol to commence treatment on the following day (Day 1). During the first 5 days the dose was increased on an every second day basis until normal bowel movement was achieved. Thereafter until the end of the study the dosage was titrated according to the stool consistency (diarrhoea, loose stool, hard stools or no bowel movement for 2 days, respectively). Four on-treatment visits were performed on Day 14 (Visit 2), Day 28 (Visit 3), Day 56 (Visit 4) and Day 84 (Visit 5). At each visit bowel movements over the preious period were assessed by the investigator using the patient’s daily diary card data.
