There are medications that increase peristalsis, such as neostigmine and tegaserod, that can be used in selected patients to help ileus resolve.
A flexible tube may be inserted into the colon to relieve pressure.
Rarely, surgery is required if there is a perforation or other abnormality causing the ileus.
Since ileus is generally the result of injury, surgery, or a medical condition, there is little that can be done to prevent it.
