It is not normal to have no stool for several days after treatment of intestinal obstruction, because the etiology of intestinal obstruction usually includes adhesive intestinal obstruction, mechanical intestinal obstruction, and strangulated intestinal obstruction. In addition to mechanical intestinal obstruction, strangulated intestinal obstruction is also associated with blood flow obstruction, which requires timely surgical treatment; otherwise, ischemic necrosis of the intestinal tube may easily occur and cause toxic shock. Most of the intestinal obstruction is caused by adhesion of intestinal tube after abdominal surgery, and most of them adopt conservative treatment, that is, fasting, gastrointestinal decompression, anti-infection and rehydration treatment, and most of the adhesion intestinal obstruction can be relieved in 3-5 days through the above conservative treatment, and the anus can resume venting and defecation. Therefore, if the bowel obstruction is still not defecating for a few days after treatment, it means that the effect of cure has not been achieved, and it is necessary to continue the treatment, and if necessary, surgery.
