Poor bowel preparation for visualization means that there is still a large amount of fecal water and sludge in the bowel, which can have an impact on the process of the examination as well as the accuracy of the results.
Poor bowel preparation for observation usually occurs during colonoscopy, meaning that the bowel is not completely emptied, and there is still fecal sludge and loose stools left in the bowel, which may cause the colonoscopy to be unclear and affect the correct judgment. One can try to change the position to continue observation, if the bowel preparation is extremely poor need to re-perform the bowel preparation.
In patients with poor bowel preparation, the contents of the bowel may be removed by mannitol and enema.
Patients whose poor bowel preparation interferes with observation should be re-prepared under the direction of a physician, and the above medications should be taken under the direction of a physician.
