The yellow water after bowel cleansing suggests that the intestinal preparation is not perfect, it is not recommended to do colonoscopy, it is generally recommended to wait until after the water is clear before performing colonoscopy.
Before doing a colonoscopy, you need to drink a laxative to empty the intestines, so that it is easy to observe the intestinal situation. Yellow water, suggesting that the intestinal tract has not been completely cleaned up, there is part of the fecal residue residue, which can lead to obstruction of the field of vision during the colonoscopy, can not see the intestinal mucosal lesions or failure to enter the mirror, and so on.
Clean up the bowel and pull the watery stool and then colonoscopy is the best, at this time the intestinal tract does not have any attachment residue, will not affect the field of vision, easy to observe the whole intestinal tract.
As a gastroenterologist, if a patient needs to undergo colonoscopy and has yellow water, we would recommend that the patient continue to wait until he/she has a clear watery stool before undergoing the examination. Except for special circumstances, the specific instructions.
