In intestinal pseudo-obstruction, foods and liquids are unable to pass through the intestine, causing a build-up of food, fluid, and gas in all or part of the colon. The symptoms of this condition act like a mechanical bowel obstruction, but no blockage is found when doctors examine the intestine.
Intestinal pseudo-obstruction is caused by problems with the muscles and nerves of the intestine.
Factors that may increase your chances of intestinal pseudo-obstruction:

IV feeding may be necessary to help prevent malnutrition.
Your doctor may prescribe antibiotics to help prevent bacterial infections. In addition, medications can be used to treat muscle problems in the intestines. Changes in your medications may be made to eliminate some medications that can slow recovery from, or worsen, this condition.
In severe cases of intestinal pseudo-obstruction, surgery to remove part or your entire intestine may be necessary.
If the colon does not resume normal function after conservative management, the pressure build-up in the colon can be relieved by removing the trapped air with a colonoscope.
Many cases of intestinal pseudo-obstruction cannot be prevented. But certain measures can be taken after surgery to help avoid the complication of intestinal pseudo-obstruction. These measures include:
