If there is no bowel movement and abdominal pain after the bowel obstruction, it is not improved, and if there is no bowel movement and abdominal pain, it is improved, so it must be combined with the cause of obstruction, clinical manifestations, physical and chemical examination to determine. 1. Causes of obstruction: the existence of obstruction cannot be excluded even after defecation of intestinal obstruction, if intestinal obstruction is caused by intestinal tumor or intestinal polyp, it is necessary to surgically remove the tumor or polyp to achieve clinical relief, and the simple defecation does not mean that the intestinal tract is smooth, but it should be combined with the cause of the obstruction to evaluate. 2. Clinical manifestations: if the patient with intestinal obstruction has gas discharge, and if there is still abdominal pain, nausea, vomiting, etc., it means that the obstruction has not been lifted, and it is necessary to continue the laxative enema, and surgical treatment is needed if necessary. 3. Physicochemical examination: after the exhaust of intestinal obstruction, it is necessary to review the standing abdominal radiograph, to make clear whether there is still liquid and gas plane, if the liquid and gas plane is not significantly improved, even if the exhaust still need to continue treatment, if the intestinal obstruction is caused by the decrease of blood potassium, it is necessary to check the serum ions, if there is no corrective action, even if the exhaust is not represented by a good. Therefore, whether the intestinal obstruction is cured after exhaustion needs to be examined by standing abdominal radiographs, serum ions combined with clinical manifestations and medical history. If there is any change in condition after the occurrence of intestinal obstruction, consult with your doctor promptly.
