In the case of intestinal obstruction, sometimes the patient can pass stool after one enema, sometimes several enemas fail to pass stool, depending on the type of intestinal obstruction and the severity of the disease. If the intestinal obstruction is caused by fecaliths and the accumulation of feces is not too much, then the feces can be discharged from the body after giving an enema. Paraffin oil, saline, or soap and water are usually used. If the intestinal obstruction is due to an abdominal infection, it may be possible to pass the stool 2-3 times before it is initially passed. If the intestinal obstruction is caused by malignant tumors, even if the enema many times, the laxative effect will be very poor, so you need to go to the hospital as soon as possible to improve the relevant examination, to clarify the cause of the disease. Generally need to check the blood routine, C-reactive protein, abdominal ultrasound or abdominal CT, sometimes also need to check the colonoscopy, according to the results of the drug treatment or surgical treatment, the specific treatment plan can be consulted with the attending physician.
