PRIMARY outcome

Timeframe: Day 1

Population: Two patients in the Lumentin group withdrew prior to contrast agent intake and were withdrawn from the efficacy analysis.

SECONDARY outcome

Timeframe: Day 1

Population: Two patients in the Lumentin group withdrew prior to contrast agent intake and were withdrawn from the efficacy analysis.

The bowel filling agent was distributed along the length of small bowel, i.e. the extension. The filling of each of the 5 selected sub-segments of the small bowel in terms of extension was examined on the CT-scan by 2 investigators, independently of each other, and graded using Likert scales between 1 and 9. Extension scale: 1. No sign of contrast agent 2. Trace of contrast agent filling 3. Segment filled to ca. 25% 4. Segment filled to \>25% but \<50% 5. Filled to segment filled to 50% 6. Segment filled \> 50% but \<75% 7. Segment filled to ca. 75% 8. Segment filled to \>75% but \<100% 9. Segment filled to 100% The evaluation was made by 2 independent radiology experts. The Extension score is the sum of the grades in each sub-segment from both evaluations and hence range from 10 to 90.

SECONDARY outcome

Timeframe: Day 1

Population: Two patients in the Lumentin group withdrew prior to contrast agent intake and were withdrawn from the efficacy analysis.

The bowel filling agent caused a local widening of the bowel loop, distension. The filling of each of the 5 selected sub-segments of the small bowel in terms of distension was examined on the CT-scan by both the 2 investigators independently of each other, and graded using Likert scales between 1 and 9. Distension scale: 1. No identifiable contrast agent 2. A minimal amount of contrast agent is identified 3. Small amount of contrast agent, insufficient for placing a ROI of 6 mm 4. Amount of contrast agent just allowing for a ROI of 6 mm 5. Medium filled bowel loop 6. Slightly better than grade 5 7. Good filling 8. Optimal filling 9. Excellent or almost over distended The evaluation was made by 2 independent radiology experts. The Distension score is the sum of the grades in each sub-segment from both evaluations and hence range from 10 to 90.

Timeframe: Day 1

Population: Two patients in the Lumentin group withdrew prior to contrast agent intake and were withdrawn from the efficacy analysis.

Diagnostic ability when examining Abd-CT was assessed on the CT-scan by the 2 investigators independently of each other. The following features were assessed: * Small bowel appearance * Parenchymal organs, i.e. Pancreas, ovaries, urinary bladder * Mesenterium and omentum using a Likert scales of 1-9 ranging, where: 1.Impossible to observe details 5\. Medium 9\. Excellent resolution The evaluation was made by 2 independent radiology experts. The Diagnostic ability score is the sum of the scores of each feature from both evaluations and hence range from 6 to 54.

SECONDARY outcome

Timeframe: Day 1

Population: Lumentin 44 is a foam containing air, and it could be suspected that the air bubbles would not withstand the condition in the stomach/intestines. Therefore, the end point Degradation of Contrast Agent was only valid for Lumentin 44 and it was included to prove the resisting power of Lumentin 44 and not to compare the IMP with Omnipaque or Movprep.

Degradation of Lumentin 44 was founded on the 2 characteristics; coalescence and syneresis or drainage. Coalescence: 0\. No bubbles visually detectable at the CT-scan 1\. Bubbles visually detectable at the CT-scan Syneresis or drainage: 0\. No syneresis or drainage, i.e. separation of air and liquid phases, observed 1\. Syneresis or drainage observed Signs of degradation were assessed on the CT-scan, by both Investigator and Sub-Investigator, independently of each other, in each of the 5 selected sub-segments of the small bowel. The degradation of contrast agents score is the sum of the scores in each sub-segment and range from 0 to 10.
