Bowel obstruction is a common complication of ovarian cancer, which mostly occurs in the late stage of ovarian cancer. How many times of enemas are needed for ovarian cancer intestinal obstruction depends on the condition, but in general, the number of enemas should not be more than three a day. There are many reasons for ovarian cancer patients to suffer from intestinal obstruction, among which the most common one is that the tumor is large and presses the intestinal lumen, which narrows the lumen and leads to the obstruction of intestinal contents, thus causing intestinal obstruction. However, since ovarian cancer patients are physically weak and enema may cause many complications, enema should not be given more than three times in general. Ovarian cancer patients with intestinal obstruction may suffer from abdominal pain, vomiting, nausea and other symptoms, and they should consult doctor in time and take appropriate treatment plan under doctor’s guidance when uncomfortable symptoms appear.
