Generally speaking, how long it takes to have normal bowel movement after rectal cancer surgery is still very much related to the distance of the tumor from the anal position before surgery. If the distance of the tumor from the anus is more than 10cm, the recovery will be faster, which is normally 2-3 weeks. However, if the distance from the anus is closer, 5-10cm, it may take a longer time to recover, which is about a few months to 1 year. If it is even closer, for example, less than 5cm, it can not do anterior incision surgery, but only abdominal echogenic combined radical treatment, so that it is necessary to do artificial anus, it does not matter the problem of defecation recovery. It is recommended that patients should consult the doctor in time if they have any discomfort, and should not be negligent so as not to delay their condition.
