Study About Contrast Media

Not Applicable

Recruiting

• Conditions: Small Bowel Obstruction

• Registration Number: NCT05678023
• Lead Sponsor: University of Tartu

Brief Summary

Patients hospitalized with adhesive small bowel obstruction (SBO) are randomized to 2 study groups at admission after signing an informed consent form. Water-soluble contrast media (CM) will be administered after 4 or after 24 hours of nasogastric- tube decompression.

Detailed Description

Patients presenting with symptoms of small bowel obstruction (SBO) will be evaluated and if the diagnosis of adhesive small bowel obstruction is made it must be decided what is the treatment of choice.

If immediate surgery is needed- it will not be delayed If patients are eligible for conservative management- they will be randomized to 2 study groups- contrast media (CM) after 4 hours of nasogastric-tube decompression and after 24 hours of nasogastric-tube decompression.

Contrast media challenge acquires radiographs (X-rays) to be taken after an interval (common practice) decided by the surgeon.

If at any point patient needs surgery- it will not be delayed. The results are compared. The hypothesis is, that if CM is administered sooner- it will help SBO resolution
